If we xfs_mdrestore an image from a non-crc filesystem, lo and behold the restored image has gained a CRC: # db/xfs_metadump.sh -o /dev/sdc1 - | xfs_mdrestore - test.img # xfs_db -c "sb 0" -c "p crc" /dev/sdc1 crc = 0 (correct) # xfs_db -c "sb 0" -c "p crc" test.img crc = 0xb6f8d6a0 (correct) This is because xfs_sb_from_disk doesn't fill in sb_crc, but xfs_sb_to_disk(XFS_SB_ALL_BITS) does write the in-memory CRC to disk - so we get uninitialized memory on disk. Fix this by always initializing sb_crc to 0 when we read the superblock, and masking out the CRC bit from ALL_BITS when we write it.

Thus all the other filesystems are just wasting memory with these fields. On the other hand it isn't simple to just move these fields to filesystem specific part of inode because there is generic code which needs to peek into the fields and it is cumbersome to provide helpers into which fs has to stuff the field it is storing elsewhere. We create a simple infrastructure which allows for optional inode fields stored in the fs-specific part of the inode. Accessing these fields has a slightly worse performance as we have to lookup their offset in the offset table stored in the superblock but in most cases this is acceptable. Notably, this offset-table mechanism is faster than having fs-specific hook functions which would need to be called to provide pointers to desired fields.

Thus filesystems which don't need it save 2 pointers in their inodes (would be 3 after we add project quota support into generic quota). I have patches to move inode->i_data.private_list into filesystem private part of the inode which is going to save another 2 pointers using the same mechanism. However I didn't want to mix those in. The patch series also contains a change to quotactl so that each filesystem can set quota types it supports. This is in the end unrelated change (originally it was necessary for i_dquot moving but in the end I changed things so that it's not anymore). I can move that into a separate series but I was somewhat reluctant to do that since that would mean another 6 one-line patches to the same files we are changing here... Comments are welcome.

We cannot just pass quota pointers from filesystems to quota functions because during quotaon and quotaoff we have to traverse list of all inodes and manipulate i_dquot pointers for each inode. Firstly, we setup optional inode field so that it points at i_dquot array in struct inode and convert quota code to use the accessor function.

In addition to simplifying the callers this also prepares for passing a per-operation O_DSYNC flag. Two callers didn't quite fit that scheme: - dio_complete didn't both to update ki_pos as we don't need it on a iocb that is about to be freed, so we had to add it. Additionally it also synced out written data in the error case, which has been changed to operate like the other callers. - gfs2 also used generic_write_sync to implement a crude version of fallocate. It has been switched to use an open coded variant instead.

It might make sense to add a = check: if (field < IF_FIELD_NR) but I'm not sure if the overhead is worthwhile, unless it can always be resolved at compile time. That might be possible since this is a static inline function.

The initial loop in this patch should be looping through all the log items on the buffer to see which items have xfs_iflush_done as their callback function. But currently, only the log item passed to the function has its callback compared to xfs_iflush_done. If the log item pointer passed to the function does have the xfs_iflush_done callback function, then all the log items on the buffer are removed from the li_bio_list on the buffer b_fspriv and could be removed from the AIL eventhough they may have not been written yet.

Looks like a bug, but what I don't know from this description is the symptoms and impact of this bug being hit? Is there a risk of filesystem corruption on crash or power loss? Perhaps it's a data loss issue? I can't tell, and for anyone scanning the commit logs to determine if they need to backport the fix will be asking the same questions. Also, is there a reproducable test case for it? > Signed-off-by: Mark Tinguely > --- > fs/xfs/xfs_inode_item.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > Index: b/fs/xfs/xfs_inode_item.c > =================================================================== > --- a/fs/xfs/xfs_inode_item.c > +++ b/fs/xfs/xfs_inode_item.c > @@ -615,7 +615,7 @@ xfs_iflush_done( > blip = bp->b_fspriv; > prev = NULL; > while (blip != NULL) { > - if (lip->li_cb != xfs_iflush_done) { > + if (blip->li_cb != xfs_iflush_done) { Looks correct, but more info needed...

There are already xfs_fsr tests that are dependent on forkoff being set to correctly defrag a file successfully. The fact that nobody has noticed that these fail tends to imply nobody runs xfstests with a 32 bit userspace on 64 bit kernels....

I've got some hacked up xfs_io support, but Milosz was planning a slight revision of the syscall interface that I'm still waiting for. How would you want to automatically test for data integrity? That requires a powerfail or crash unfortunately and we don't have good infrastructure for that yet. I've tested it by adding a printk that RWF_DSYNC triggers the same code path as O_DSYNC.

E.g., it attempts to allocate zeroed blocks over the range specified by the caller. The XFS implementation kills all delalloc blocks currently over the aligned range, converts the range to allocated zero blocks (unwritten extents) and handles the partial pages at the ends of the range by sending writes through the pagecache. The current implementation suffers from several problems associated with inode size. If the aligned range covers an extending I/O, said I/O is discarded and an inode size update from a previous write never makes it to disk. Further, if an unaligned zero range extends beyond eof, the page write induced for the partial end page can itself increase the inode size, even if the zero range request is not supposed to update i_size (via KEEP_SIZE, similar to an fallocate beyond EOF). Update xfs_zero_file_space() to forego using buffered I/O for partial pages. Instead, convert the block aligned (rather than page aligned) range to unwritten extents, update the partial blocks on disk and use existing pagecache functionality to ensure cached pages are consistent with data on disk. Signed-off-by: Brian Foster --- This passes xfstests and survived an overnight fsx run (+300m ops) on a 1k fsb fs. The tradeoff that I've observed from this implementation is that fzero is now also likely to trigger the problem described in the recently posted xfs/053 test: http://oss.sgi.com/archives/xfs/2014-09/msg00473.html This is slightly unfortunate, but as I understand it that problem is more fundamentally associated with extent conversion and writeback vs. any particular fs operation that might expose it.

I was looking in this code for a way an inode could be removed from the AIL but not written to disk. I have a metadata dump that shows a truncate on two inodes just before a clean unmount. The free space btrees are updated but neither inode has been updated. A clean shutdown will wait until the AIL is empty, so something removed the inode from the AIL but did not write the latest changes to disk. Yes, there were earlier changes to inode/chunk in previous pushes. This results in the blocks being both free and allocated....if we are lucky, we get a XFS_WANT_CORRUPTED_GOTO forced shutdowns because of partial frees in xfs_free_ag_extent(). Most of the time it is reallocated and that leads to all kinds of data/metadata corruption. I tried to recreate the problem with truncates on files while unmounting but have not gotten the correct combination. I have been chasing the ghost of the duplicate allocation corruption problem for months and I did not want to over state my beliefs until I could replicate the problem.

We have the infrastructure in xfstests to do this in a generic way: use dm-flakey. The fsync tests (generic/311, generic/32[23]) that Josef wrote that use dm-flakey to prevent writes after the IOs have completed and check that the data is there after remount. Similarly, for xfs specific tests we have older tests that use the shutdown ioctl (e.g. xfs/137-139) by using the godown function to shut the filesystem down and prevent unmount from writing metadata. On remount the data should be present. So there's a couple of different ways you can do this...

If the inode is dirty in reclaim (i.e. has outstanding dirty fields in the log item) then it will be written - the presence in the AIL is not necessary for this to occur. These dirty flags are only cleared when the inode is flushed to the buffer and attached to it, so the presence of these fields assumes the inode is in the AIL. i.e. if reclaim didn't write the inodes out, it means the last operation that happened on these inodes was xfs_iflush() and they were cleaned and written to disk correctly. > so something removed the inode from the AIL but did > not write the latest changes to disk. Yes, there were earlier > changes to inode/chunk in previous pushes. Let's look at this from a different perspective: how does the inode get attached to the buffer in the first place so it can be removed from the AIL in xfs_iflush_done()? The only way inodes get attached to the buffer through xfs_buf_attach_iodone() via either xfs_iflush() or xfs_ifree_cluster(). xfs_iflush() is only called when an inode is either being pushed from the AIL or being reclaimed and it is dirty. xfs_ifree_cluster() is only called when an inode chunk is being deallocated. Hence, any inode on the buffer iodone list is either currently being written or the extent it lies in has just been freed and it will never get written. When an inode chunk is being freed via xfs_ifree_cluster(), all the inodes attached to the buffer have their iodone functions changed to xfs_istale_done(). Hence we have the situation where all the inodes on a buffer have the same callbacks: either xfs_istale_done() or xfs_iflush_done(). And on buffer IO completion, all the inodes on the buffer should be cleaned at the same time, and hence all should have their completions run. If the inode is modified by another transaction while the push is in progress, the inode will be moved forward in the AIL. It will have a more recent LSN than the flush in progress. Hence this check in xfs_iflush_done() when determining if the inode should be removed from the AIL: if (iip->ili_logged && blip->li_lsn == iip->ili_flush_lsn) { log_items[i++] = blip; } i.e. it only removes the item from the AIL if the flush LSN is unchanged from when the inode was flushed to the buffer. Hence I can't see how the existing code can result in removing a dirty inode from the AIL without it being written to the buffer first (and hence cleaned), nor if such a problem occurred how such a dirty inode can make it through reclaim during unmount without being seen as dirty and written to disk. I agree that we should fix the code to be exactly correct, but I can't see how the code as is stands behaves any differently from the fixed version, nor how it would be responsible for the problem in the metadump you analysed.... I'll rework the commit message appropriately.

There's significant complexity now in xfs_buf_iorequest() to specifically handle this sort of synchronous IO pattern, but there's all sorts of nasty surprises in different error handling code dependent on who owns the buffer references and the locks. Pull this pattern into a single helper, where we can hide all the synchronous IO warts and hence make the error handling for all the callers much saner. This removes the need for a special extra reference to protect IO completion processing, as we can now hold a single reference across dispatch and waiting, simplifying the sync IO smeantics and error handling. In doing this, also rename xfs_buf_iorequest to xfs_buf_submit and make it explicitly handle on asynchronous IO. This forces all users to be switched specifically to one interface or the other and removes any ambiguity between how the interfaces are to be used. It also means that xfs_buf_iowait() goes away.

Internal buffer write error handling is a mess due to the unnatural split between xfs_bioerror and xfs_bioerror_relse(). xfs_bwrite() only does sync IO and determines the handler to call based on b_iodone, so for this caller the only difference between xfs_bioerror() and xfs_bioerror_release() is the XBF_DONE flag. We don't care what the XBF_DONE flag state is because we stale the buffer in both paths - the next buffer lookup will clear XBF_DONE because XBF_STALE is set. Hence we can use common error handling for xfs_bwrite(). __xfs_buf_delwri_submit() is a similar - it's only ever called on writes - all sync or async - and again there's no reason to handle them any differently at all.

The issue is that this is racy w.r.t. synchronous IO - the submitter can see b_error being set before the IO is complete, and hence we cannot differentiate between submission failures and completion failures. Add an internal b_io_error field protected by the b_lock to catch IO completion errors, and only propagate that to the buffer during final IO completion handling. Hence we can tell in xfs_buf_iorequest if we've had a submission failure bey checking bp->b_error before dropping our b_io_remaining reference - that reference will prevent b_io_error values from being propagated to b_error in the event that completion races with submission.

The IO "hold reference" is owned by the submitter, and released when the submission is complete. The IO reference is released when both the submitter and the bio end_io processing is run, and so if the io completion work is run from IO completion context, it is run without an IO reference. Hence we can get the situation where the submitter can submit the IO, see an error on the buffer and unlock and free the buffer while there is still IO in progress. This leads to use-after-free and memory corruption. Fix this by taking a "sync IO hold" reference that is owned by the IO and not released until after the buffer completion calls are run to wake up synchronous waiters. This means that the buffer will not be freed in any circumstance until all IO processing is completed.

The second pass to call xfs_buf_iowait() can be replaced with blocking on xfs_buf_lock() - the buffer will be unlocked when the async IO is complete. This formalises a sane the method of waiting for async IO - take an extra reference, submit the IO, call xfs_buf_lock() when you want to wait for IO completion. i.e.: bp = xfs_buf_find(); xfs_buf_hold(bp); bp->b_flags |= XBF_ASYNC; xfs_buf_iosubmit(bp); xfs_buf_lock(bp) error = bp->b_error; .... xfs_buf_relse(bp); While this is somewhat racy for gathering IO errors, none of the code that calls xfs_buf_delwri_submit() will race against other users of the buffers being submitted. Even if they do, we don't really care if the error is detected by the delwri code or the user we raced against. Either way, the error will be detected and handled.

However, we currently force the log after marking the filesystem as shut down, hence allowing IO to the log *after* we have marked both the filesystem and the log as in an error state. Clean this up by forcing the log before we mark the filesytem with an error. This replaces the pure CIL flush that we currently have which works around this same issue (i.e the CIL can't be flushed once the shutdown flags are set) and hence enables us to clean up the logic substantially.

The initial loop in this patch should be looping through all the log items on the buffer to see which items have xfs_iflush_done as their callback function. But currently, only the log item passed to the function has its callback compared to xfs_iflush_done. If the log item pointer passed to the function does have the xfs_iflush_done callback function, then all the log items on the buffer are removed from the li_bio_list on the buffer b_fspriv and could be removed from the AIL even though they may have not been written yet. This problem is masked by the fact that currently all inodes on a buffer will have the same calback function - either xfs_iflush_done or xfs_istale_done - and hence the bug cannot manifest in any way. Still, we need to remove the landmine so that if we add new callbacks in future this doesn't cause us problems.

Unaligned start and end offsets are zeroed through the page cache and the internal, aligned blocks are converted to unwritten extents. If EOF is page aligned and covered by a delayed allocation extent. The inode size is not updated until I/O completion. If a zero range request discards a delalloc range that covers page aligned EOF as such, the inode size update never occurs. For example: $ rm -f /mnt/file $ xfs_io -fc "pwrite 0 64k" -c "zero 60k 4k" /mnt/file $ stat -c "%s" /mnt/file 65536 $ umount /mnt $ mount /mnt $ stat -c "%s" /mnt/file 61440 Update xfs_zero_file_space() to flush the range rather than discard delalloc blocks to ensure that inode size updates occur appropriately. [dchinner: Note that this is really a workaround to avoid the underlying problems. More work is needed (and ongoing) to fix those issues so this fix is being added as a temporary stop-gap measure. ] Signed-off-by: Brian Foster Reviewed-by: Dave Chinner Signed-off-by: Dave Chinner commit 07d08681d26e99d8ba3bc4e56380f2cc04d3ff3b Author: Brian Foster Date: Thu Oct 2 09:42:06 2014 +1000 xfs: restore buffer_head unwritten bit on ioend cancel xfs_vm_writepage() walks each buffer_head on the page, maps to the block on disk and attaches to a running ioend structure that represents the I/O submission. A new ioend is created when the type of I/O (unwritten, delayed allocation or overwrite) required for a particular buffer_head differs from the previous. If a buffer_head is a delalloc or unwritten buffer, the associated bits are cleared by xfs_map_at_offset() once the buffer_head is added to the ioend. The process of mapping each buffer_head occurs in xfs_map_blocks() and acquires the ilock in blocking or non-blocking mode, depending on the type of writeback in progress. If the lock cannot be acquired for non-blocking writeback, we cancel the ioend, redirty the page and return. Writeback will revisit the page at some later point. Note that we acquire the ilock for each buffer on the page. Therefore during non-blocking writeback, it is possible to add an unwritten buffer to the ioend, clear the unwritten state, fail to acquire the ilock when mapping a subsequent buffer and cancel the ioend. If this occurs, the unwritten status of the buffer sitting in the ioend has been lost. The page will eventually hit writeback again, but xfs_vm_writepage() submits overwrite I/O instead of unwritten I/O and does not perform unwritten extent conversion at I/O completion. This leads to data corruption because unwritten extents are treated as holes on reads and zeroes are returned instead of reading from disk. Modify xfs_cancel_ioend() to restore the buffer unwritten bit for ioends of type XFS_IO_UNWRITTEN. This ensures that unwritten extent conversion occurs once the page is eventually written back.

If we xfs_mdrestore an image from a non-crc filesystem, lo and behold the restored image has gained a CRC: # db/xfs_metadump.sh -o /dev/sdc1 - | xfs_mdrestore - test.img # xfs_db -c "sb 0" -c "p crc" /dev/sdc1 crc = 0 (correct) # xfs_db -c "sb 0" -c "p crc" test.img crc = 0xb6f8d6a0 (correct) This is because xfs_sb_from_disk doesn't fill in sb_crc, but xfs_sb_to_disk(XFS_SB_ALL_BITS) does write the in-memory CRC to disk - so we get uninitialized memory on disk. Fix this by always initializing sb_crc to 0 when we read the superblock, and masking out the CRC bit from ALL_BITS when we write it.

For example: $ xfs_io -fc "pwrite `echo "2^63-1-1" | bc` 1" /mnt/file wrote 1/1 bytes at offset 9223372036854775806 1.000000 bytes, 1 ops; 0.0000 sec (22.711 KiB/sec and 23255.8140 ops/sec) $ stat -c %s /mnt/file 9223372036854775807 $ umount /mnt ; mount /mnt/ $ stat -c %s /mnt/file 0 This occurs because XFS calculates the new file size as io_offset + io_size, I/O occurs in block sized requests, and the maximum supported file size is not block aligned. Therefore, a write to the max allowable offset on a 4k blocksize fs results in a write of size 4k to offset 2^63-4096 (e.g., equivalent to round_down(2^63-1, 4096), or IOW the offset of the block that contains the max file size). The offset plus size calculation (2^63 - 4096 + 4096 == 2^63) overflows the signed 64-bit variable which goes negative and causes the > comparison to the on-disk inode size to fail. This returns 0 from xfs_new_eof() and results in no change to the inode on-disk. Update xfs_new_eof() to explicitly detect overflow of the local calculation and use the VFS inode size in this scenario. The VFS inode size is capped to the maximum and thus XFS writes the correct inode size to disk.

This is the third revision of the series. The others are available here: http://oss.sgi.com/archives/xfs/2014-09/msg00260.html http://oss.sgi.com/archives/xfs/2014-09/msg00169.html In response to feedback for v2, the changes in v3 include: ** trie size is reduced from 245kB to 90kB by using algorithmic decomposition * robustness fixes to the trie generator mkutf8data.c * mkutf8data.c moved to scripts/, utf8 normalization module moved to lib/, and compiled under CONFIG_UTF8_NORMALIZATION * removed CONFIG_XFS_UTF8_DEMAND_LOAD, now it is unconditional * the unicode version is stored in the superblock, checked at mount time, and passed through to the normalization module. * add a versioned fsgeometry ioctl, and xfs_info bits to print the unicode version * TODO don't overload asciici feature bit * TODO fix patch klunkiness in xfs_da_mount In response to the initial feedback, the changes in version 2 include: * linux-fsdevel in the To: line, * Updated design notes, * Separation of the fs-independent trie and support code into utf8norm.ko, * A mechanism for loading the normalization module only when necessary. I'll post the whole series for completeness sake. Many on -fsdevel will not be interested in the xfs-specific bits, but it may be helpful to have the full series as an example and for testing purposes. First there is a set of kernel bits, then some libxfs/xfsprogs stuff, and finally a test. (Note: I am not posting the unicode database files due to their large size. There are scripts to download them from unicode.org in the relevant commit headers.) Thanks, Ben Here are Olaf's design notes: ----------------------------------------------------------------------------- Unicode/UTF-8 support for XFS So we had a customer request proper unicode support... * What does "supporting unicode" actually mean? >From a text processing point of view, what a filesystem does with filenames is simple: it stores and retrieves them, and compares them for equality. It may reject certain byte sequences as invalid filenames (for example, no filename can contain an ASCII NUL). I've been taking it as a given that when a file is created with a certain byte sequence as its name, then a subsequent directory listing will contain that same byte sequence among the names listed. That things ought to work like that is either obvious to the point of being axiomatic, or -- I suppose -- not. The reader gets one (1) guess as to which camp I'm in. This leaves comparing names for equality, and in my view this is what "supporting unicode" revolves about. The present state of affairs is that different byte sequences are different filenames. This amounts to tolerating unicode without actually supporting it. To support unicode we have to interpret filenames. What happens when (part of) a filename cannot be interpreted? We can reject the filename, interpret the parts we can, or punt and accept it as an uninterpreted blob. Rejecting ill-formed filenames was my first choice, but I came around on the issue: there are too many ways in which you can end up with having to deal with ill-formed filenames that would leave a user with no recourse but to move whatever they're doing to a different filesystem. Unpacking a tarball with filenames in a different encoding is an example. Partial interpretation of an ill-formed filename just strikes me as the kind of bad idea that most half-houses are. I admit that I have no stronger objection to this than the fact that it makes the code even more complicated and fragile. Which leaves "blob" as the preferred option by default for coping with ill-formed filenames. When comparing well-formed filenames, the question now becomes which byte sequences are considered to be alternative spellings of the same filename. This is where normalization forms come into play, and the unicode standard has quite a bit to say about the subject. If all you're doing is comparison, then choosing NFD over NFC is easy, because the former is easier to calculate than the latter. If you want various spellings of "office" to compare equal, then picking NFKD over NFD for comparison is also an obvious choice. (Hand-picking individual compatibility forms is truly a bad idea.) Ways to spell "office": "o_f_f_i_c_e", "o_f_fi_c_e", and "o_ffi_c_e", using no ligatures, the fi ligature, or the ffi ligature. (Some fool thought it a good idea to add these ligatures to unicode, all we get to decide is how to cope.) The most contentious part is (should be) ignoring the codepoints with the Default_Ignorable_Code_Point property. I've included the list below. My argument, such as it is, is that these code points either have no visible rendering, or in cases like the soft hyphen, are only conditionally visible. The problem with these (as I see it) is that on seeing a filename that might contain them you cannot tell whether they are present. So I propose to ignore them for the purpose of comparing filenames for equality. Finally, case folding. First of all, it is optional. Then the issue is that you either go the language-specific route, or simplify the task by "just" doing a full casefold (C+F, in unicode parlance). Looking around the net I tend to find that if you're going to do casefolding at all, then a language-independent full casefold is preferred because it is the most predictable option. See http://www.w3.org/TR/charmod-norm/ for an example of that kind of reasoning. All of these choices can be argued with, but I do believe that the particular combination of choices I made is a defensible one. The code refers to these normalization forms as nfkdi and nfkdicf. * XFS-specific design notes. XFS uses byte strings for filenames, so UTF-8 is the expected format for unicode filenames. This does raise the question what criteria a byte string must meet to be UTF-8. We settled on the following: - Valid unicode code points are 0..0x10FFFF, except that - The surrogates 0xD800..0xDFFF are not valid code points, and - Valid UTF-8 must be a shortest encoding of a valid unicode code point. In addition, U+0 (ASCII NUL, '\0') is used to terminate byte strings (and is itself not part of the string). Moreover strings may be length-limited in addition to being NUL-terminated (there is no such thing as an embedded NUL in a length-limited string). The code uses ("leverages", in corp-speak) the existing XFS infrastructure for case-insensitive filenames. Like the CI code, the name used to create a file is stored on disk, and returned in a lookup. When comparing filenames the normalized forms of the names being compared are generated on the fly from the non-normalized forms stored on disk. If the borgbit (the bit enabling legacy ASCII-based CI in XFS) is set in the superblock, then case folding is added into the mix. This is the nfkdicf normalization form mentioned above. It allows for the creation of case-insensitive filesystems with UTF-8 support. * Implementation notes. Strings are normalized using a trie that stores the relevant information. The trie itself is about 250kB in size, and lives in a separate module. The trie is not checked in: instead we add the source files from the Unicode Character Database and a program that creates the header containing the trie. The key for a lookup in the trie is a UTF-8 sequence. Each valid UTF-8 sequence leads to a leaf. No invalid sequence does. This means that trie lookups can be used to validate UTF-8 sequences, which why there is no specialized code for the same purpose. The trie contains information for the version of unicode in which each code point was defined. This matters because non-normalized strings are stored on disk, and newer versions of unicode may introduce new normalized forms. Ideally, the version of unicode used by the filesystem is stored in the filesystem. The trie also accounts for corrections made in the past to normalizations. This has little value today, because any newly created filesystem would be using unicode version 7.0.0. It is included in order to show, not tell, that such corrections can be handled if they are added in future revisions. The algorithm used to calculate the sequences of bytes for the normalized form of a UTF-8 string is tricky. The core is found in utf8byte(), with an explanation in the preceeding comment. The non-XFS-specific supporting code functions have the prefix 'utf8n' if they handle length-limited strings, and 'utf8' if they handle NUL-terminated strings. ---- # Derived Property: Default_Ignorable_Code_Point # Generated from # Other_Default_Ignorable_Code_Point # + Cf (Format characters) # + Variation_Selector # - White_Space # - FFF9..FFFB (Annotation Characters) # - 0600..0605, 06DD, 070F, 110BD (exceptional Cf characters that should be visible) 00AD ; Default_Ignorable_Code_Point # Cf SOFT HYPHEN 034F ; Default_Ignorable_Code_Point # Mn COMBINING GRAPHEME JOINER 061C ; Default_Ignorable_Code_Point # Cf ARABIC LETTER MARK 115F..1160 ; Default_Ignorable_Code_Point # Lo [2] HANGUL CHOSEONG FILLER..HANGUL JUNGSEONG FILLER 17B4..17B5 ; Default_Ignorable_Code_Point # Mn [2] KHMER VOWEL INHERENT AQ..KHMER VOWEL INHERENT AA 180B..180D ; Default_Ignorable_Code_Point # Mn [3] MONGOLIAN FREE VARIATION SELECTOR ONE..MONGOLIAN FREE VARIATION SELECTOR THREE 180E ; Default_Ignorable_Code_Point # Cf MONGOLIAN VOWEL SEPARATOR 200B..200F ; Default_Ignorable_Code_Point # Cf [5] ZERO WIDTH SPACE..RIGHT-TO-LEFT MARK 202A..202E ; Default_Ignorable_Code_Point # Cf [5] LEFT-TO-RIGHT EMBEDDING..RIGHT-TO-LEFT OVERRIDE 2060..2064 ; Default_Ignorable_Code_Point # Cf [5] WORD JOINER..INVISIBLE PLUS 2065 ; Default_Ignorable_Code_Point # Cn 2066..206F ; Default_Ignorable_Code_Point # Cf [10] LEFT-TO-RIGHT ISOLATE..NOMINAL DIGIT SHAPES 3164 ; Default_Ignorable_Code_Point # Lo HANGUL FILLER FE00..FE0F ; Default_Ignorable_Code_Point # Mn [16] VARIATION SELECTOR-1..VARIATION SELECTOR-16 FEFF ; Default_Ignorable_Code_Point # Cf ZERO WIDTH NO-BREAK SPACE FFA0 ; Default_Ignorable_Code_Point # Lo HALFWIDTH HANGUL FILLER FFF0..FFF8 ; Default_Ignorable_Code_Point # Cn [9] .. 1BCA0..1BCA3 ; Default_Ignorable_Code_Point # Cf [4] SHORTHAND FORMAT LETTER OVERLAP..SHORTHAND FORMAT UP STEP 1D173..1D17A ; Default_Ignorable_Code_Point # Cf [8] MUSICAL SYMBOL BEGIN BEAM..MUSICAL SYMBOL END PHRASE E0000 ; Default_Ignorable_Code_Point # Cn E0001 ; Default_Ignorable_Code_Point # Cf LANGUAGE TAG E0002..E001F ; Default_Ignorable_Code_Point # Cn [30] ..

Signed-off-by: Olaf Weber --- [v2: the trie is now separated into utf8norm.ko; utf8version is now a function and exported; introduced CONFIG_XFS_UTF8; removed supporting code due to vger size constraint. --bpm] [v3: moved trie generator to scripts/; introduced CONFIG_UTF8_NORMALIZATION. --bpm] --- lib/Kconfig | 8 + lib/Makefile | 13 + scripts/Makefile | 1 + scripts/mkutf8data.c | 3239 ++++++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 3261 insertions(+) create mode 100644 scripts/mkutf8data.c diff --git a/lib/Kconfig b/lib/Kconfig index a5ce0c7..c92dfd8 100644 --- a/lib/Kconfig +++ b/lib/Kconfig @@ -515,4 +515,12 @@ source "lib/fonts/Kconfig" config ARCH_HAS_SG_CHAIN def_bool n +# +# utf8 normalization module +# +config UTF8_NORMALIZATION + tristate "UTF-8 normalization support" + help + Say Y here to enable utf8 normalization support. + endmenu diff --git a/lib/Makefile b/lib/Makefile index d6b4bc4..b0b0d57 100644 --- a/lib/Makefile +++ b/lib/Makefile @@ -196,3 +196,16 @@ quiet_cmd_build_OID_registry = GEN $@ clean-files += oid_registry_data.c obj-$(CONFIG_UCS2_STRING) += ucs2_string.o + +$(obj)/utf8data.h: $(src)/ucd/*.txt $(objtree)/scripts/mkutf8data FORCE + $(call cmd,mkutf8data) +quiet_cmd_mkutf8data = MKUTF8DATA $@ + cmd_mkutf8data = $(objtree)/scripts/mkutf8data \ + -a $(src)/ucd/DerivedAge-7.0.0.txt \ + -c $(src)/ucd/DerivedCombiningClass-7.0.0.txt \ + -p $(src)/ucd/DerivedCoreProperties-7.0.0.txt \ + -d $(src)/ucd/UnicodeData-7.0.0.txt \ + -f $(src)/ucd/CaseFolding-7.0.0.txt \ + -n $(src)/ucd/NormalizationCorrections-7.0.0.txt \ + -t $(src)/ucd/NormalizationTest-7.0.0.txt \ + -o $@ diff --git a/scripts/Makefile b/scripts/Makefile index 72902b5..80fcf43 100644 --- a/scripts/Makefile +++ b/scripts/Makefile @@ -16,6 +16,7 @@ hostprogs-$(CONFIG_VT) += conmakehash hostprogs-$(BUILD_C_RECORDMCOUNT) += recordmcount hostprogs-$(CONFIG_BUILDTIME_EXTABLE_SORT) += sortextable hostprogs-$(CONFIG_ASN1) += asn1_compiler +hostprogs-$(CONFIG_UTF8_NORMALIZATION) += mkutf8data HOSTCFLAGS_sortextable.o = -I$(srctree)/tools/include HOSTCFLAGS_asn1_compiler.o = -I$(srctree)/include diff --git a/scripts/mkutf8data.c b/scripts/mkutf8data.c new file mode 100644 index 0000000..1d6ec02 --- /dev/null +++ b/scripts/mkutf8data.c @@ -0,0 +1,3239 @@ +/* + * Copyright (c) 2014 SGI. + * All rights reserved. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it would be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Message-ID: <20141003215414.GB1865@sgi.com> References: <20141003214758.GY1865@sgi.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20141003214758.GY1865@sgi.com> User-Agent: Mutt/1.5.20 (2009-06-14) From: Olaf Weber Supporting functions for UTF-8 normalization are in utf8norm.c with the header utf8norm.h. Two normalization forms are supported: nfkdi and nfkdicf. nfkdi: - Apply unicode normalization form NFKD. - Remove any Default_Ignorable_Code_Point. nfkdicf: - Apply unicode normalization form NFKD. - Remove any Default_Ignorable_Code_Point. - Apply a full casefold (C + F). For the purposes of the code, a string is valid UTF-8 if: - The values encoded are 0x1..0x10FFFF. - The surrogate codepoints 0xD800..0xDFFFF are not encoded. - The shortest possible encoding is used for all values. The supporting functions work on null-terminated strings (utf8 prefix) and on length-limited strings (utf8n prefix).

To store the decomposition the caller of utf8lookup()/utf8nlookup() must provide a 12-byte buffer, which is used to synthesize a leaf with the decomposition. Trie size is reduced from 245kB to 90kB. This change also contains a number of robustness fixes to the trie generator mkutf8data.c.

Whether a filesystem uses case-insensitive lookups is determined by a superblock bit set during filesystem creation. This means that normal use cannot create two files that both match the same filename.

Convert sb_pad to sb_utf8version in the super block.

Message-ID: <20141003220757.GS1865@sgi.com> References: <20141003214758.GY1865@sgi.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20141003214758.GY1865@sgi.com> User-Agent: Mutt/1.5.20 (2009-06-14) From: Olaf Weber Supporting functions for UTF-8 normalization are in utf8norm.c with the header utf8norm.h. Two normalization forms are supported: nfkdi and nfkdicf. nfkdi: - Apply unicode normalization form NFKD. - Remove any Default_Ignorable_Code_Point. nfkdicf: - Apply unicode normalization form NFKD. - Remove any Default_Ignorable_Code_Point. - Apply a full casefold (C + F). For the purposes of the code, a string is valid UTF-8 if: - The values encoded are 0x1..0x10FFFF. - The surrogate codepoints 0xD800..0xDFFFF are not encoded. - The shortest possible encoding is used for all values. The supporting functions work on null-terminated strings (utf8 prefix) and on length-limited strings (utf8n prefix).

To store the decomposition the caller of utf8lookup()/utf8nlookup() must provide a 12-byte buffer, which is used to synthesize a leaf with the decomposition. Trie size is reduced from 245kB to 90kB. This change also contains a number of robustness fixes to the trie generator mkutf8data.c.

Whether a filesystem uses case-insensitive lookups is determined by a superblock bit set during filesystem creation. This means that normal use cannot create two files that both match the same filename.

The xfs_utf8_ci_nameops use the nfkdicf normalization when comparing filenames, and are installed if both the utf8bit and the borgbit are set in the superblock. Normalized filenames are not stored on disk. Normalization will fail if a filename is not valid UTF-8, in which case the filename is treated as an opaque blob.

It is based on code that does testing in the trie generator. Here too we are using the NormalizationTest-7.0.0.txt file from the unicode distribution. We check that the normalization in libxfs is working and then run checks on a filesystem mounted on /mnt (currently this is hardcoded). Note that there are some 'blacklisted' unichars which normalize to reserved characters.

This patch actually addresses that particular problem, yet introduces another similar variant of the problem. The original cause is "leakage" of speculative preallocation blocks into the addressable range of the file (within eof) without any pages associated with the delalloc extent. This means that it isn't necessarily sufficient to writeback a particular delalloc range to convert it. This sets a landmine for direct I/O or inode eviction to step on when it comes time to perform I/O over the range or clean the inode. For example: # xfs_io -fc "pwrite 0 128k" -c "fzero -k 1m 54321" /mnt/file wrote 131072/131072 bytes at offset 0 128 KiB, 32 ops; 0.0000 sec (786.164 MiB/sec and 201257.8616 ops/sec) # xfs_io -d -c "pread 128k 128k" /mnt/file Segmentation fault The first command creates a delalloc extent with preallocation and then runs a non-file-size-extending zero range beyond the end of the file with an unaligned end offset (note that doing the zero range within the same process is required to ensure prealloc isn't trimmed by close()). As discussed above, this results in an internal I/O that increases i_size and leaks the previous preallocation within eof. The subsequent command simply attempts a delalloc read across where the preallocation would have started. It attempts a writeback of the range where the dellaloc exists, but there are no pages in the particular range of I/O to drive extent conversion and hence the request ultimately falls over. I haven't looked into the xfs_io crash, but the intent of the command is to reproduce the direct I/O BUG(): kernel: kernel BUG at fs/xfs/xfs_aops.c:1392! I don't reproduce the umount problem with this same sequence. I suspect this is because a writeback over the broader range of the file (e.g., 0-128k) will ultimately convert the extent. I suspect some sequence that can create contiguous but separate delalloc extents would lead to the problem on umount (e.g., a delalloc extent that has no page cache coverage whatsoever). I'm pretty sure I've seen this before when playing around with collapse but I can't quite recall how it occurs. This is important to dig into as well as anything that can lead to this naked delalloc extent scenario can cause this problem. The patch here addresses the zero range problem simply by avoiding xfs_iozero(). It introduces a similar problem... > fs/xfs/xfs_bmap_util.c | 110 +++++++++++++++++++++++++++++++++++-------------- > 1 file changed, 78 insertions(+), 32 deletions(-) > > diff --git a/fs/xfs/xfs_bmap_util.c b/fs/xfs/xfs_bmap_util.c > index d8b77b5..f2d58e2 100644 > --- a/fs/xfs/xfs_bmap_util.c > +++ b/fs/xfs/xfs_bmap_util.c > @@ -1364,7 +1364,17 @@ xfs_free_file_space( > goto out; > } > > - > +/* > + * Preallocate and zero a range of a file.

This leads to the same delalloc blocks not covered by pagecache problem. I suspect the fix is to truncate the pagecache in smaller portions as we proceed through the function, but I'll have to give it a try. I *think* it's important to handle the truncate before making any extent modifications lest weird things happen with writeback.

This is a bug within the zero range code - we should never try to sub-block zeroing beyond EOF unless we are extending the file size and need to zero blocks/prealloc that already exists. Extending the file should only be done through xfs_setattr_size(). If the range to be zeroed beyond EOF is smaller than a block, then we should just prealloc the entire block because the EOF extension (whenever it is done) will do IO that results in the block being fully zeroed, anyway. > The patch here addresses the zero range problem simply by avoiding > xfs_iozero().

Or we could just punch the delalloc blocks on failure. i.e. punching delalloc blocks is used only for error handling (like in the buffer write error handling case). It will at least "zero" the delalloc portions of the range on failure...

Further, the size of the structure that is filled in is determined by the version of the ioctl being called, not the xfs_fs_geometry() function. Hence the caller already knows the size of the structure being used, and hence does not need xfs_fs_geometry() to tell it that information. So I don't think this change is necessary.

Drop the typedef, and the structure needs to be 64 bit size aligned so we don't get problems with 32 bit userspace on 64 bit kernels (e.g. we have a v1 compat ioctl handler because of this issue). Further, lets avoid needing to rev the ioctl again in future by adding a bunch of "must be zero" padding to the new structure so we can extend the information we push to userspace easily. i.e. padding only becomes meaningful when the superblock flag that exposes meaning is set. i.e. userspace can do this to conditionally access the ut8version value if it is meaningful: utf8_ver = 0; if (geo.flags & XFS_FSOP_GEOM_FLAGS_UTF8) utf8_ver = geo->utf8version; i.e. let's make the new structure forwards compatible with new features... > @@ -115,6 +117,15 @@ xfs_fs_geometry( > XFS_FSOP_GEOM_FLAGS_LOGV2 : 0); > geo->logsunit = mp->m_sb.sb_logsunit; > } > + if (new_version >= XFS_FSOP_GEOM_VERSION5) { > + geo->version = XFS_FSOP_GEOM_VERSION5; > + geo->flags |= (xfs_sb_version_hasutf8(&mp->m_sb) ? > + XFS_FSOP_GEOM_FLAGS_UTF8 : 0); > + geo->utf8version = mp->m_sb.sb_utf8version; > + if (bytes) > + *bytes = sizeof(xfs_fsop_geom_v2_t) + > + sizeof(geo->utf8version); Further indication that the *bytes variable should die. > + } > return 0; > } > > diff --git a/fs/xfs/xfs_fsops.h b/fs/xfs/xfs_fsops.h > index 74e1fee..b723f36 100644 > --- a/fs/xfs/xfs_fsops.h > +++ b/fs/xfs/xfs_fsops.h > @@ -18,7 +18,7 @@ > #ifndef __XFS_FSOPS_H__ > #define __XFS_FSOPS_H__ > > -extern int xfs_fs_geometry(xfs_mount_t *mp, xfs_fsop_geom_v2_t *geo, > +extern int xfs_fs_geometry(xfs_mount_t *mp, void *buffer, > int new_version, size_t *bytes); > extern int xfs_growfs_data(xfs_mount_t *mp, xfs_growfs_data_t *in); > extern int xfs_growfs_log(xfs_mount_t *mp, xfs_growfs_log_t *in); > diff --git a/fs/xfs/xfs_ioctl.c b/fs/xfs/xfs_ioctl.c > index 1657ce5..6308680 100644 > --- a/fs/xfs/xfs_ioctl.c > +++ b/fs/xfs/xfs_ioctl.c > @@ -859,6 +859,34 @@ xfs_ioc_fsgeometry_v2( > return 0; > } > > +STATIC int > +xfs_ioc_fsgeometry( > + struct xfs_mount *mp, > + void __user *arg) > +{ > + xfs_fsop_geom_t fsgeo; > + int version, error; > + size_t bytes; > + > + /* offsetof(version)?

This avoids git bisects landing on commits in the series where the filesystem says it supports the feature bit it doesn't actually work.

The way it fell out, I didn't end up using xfs_iozero() at all. Technically, it still has the potential to do sub-block zeroing post-eof, but it doesn't matter because it isn't doing buffered I/O. Sure, it's pointless in the post-eof case, but not problematic and not something I thought worth complicating the code over. FWIW, I also don't really see any reason to reintroduce xfs_iozero() into this rework. The larger point is that the current, broken zero range seems to also be a primary cause of the umount and direct I/O delalloc asserts that I see via generic/269. BTW, any thoughts on how we could end up with contiguous but independent delalloc extents in the in-core list? > > The patch here addresses the zero range problem simply by avoiding > > xfs_iozero().

IOW, we can probably get this behavior with a significantly more simple implementation that basically consists of a page cache truncate, a call to xfs_free_file_space() and a call to xfs_alloc_file_space(). That unnecessarily punches out all extents rather than just the delalloc extents, but also naturally leaves the file in an expected state (the range is zeroed) if the preallocation fails anywhere along the way. I'm wondering if it's worth it. Thoughts?

So, what happens if this memory allocation fails in the middle of a create transaction? (Hint: transaction is dirty at this point in time) The rest of the code in this patch has similar issues to what I've already pointed out.

I see no reason apart from "it's less typing" to drop the use of the xfs-name structure, but it removes a key piece of documentation from the code. i.e. that the name/namelen are an inseparable tuple and cannot be separated. Indeed, lots of the utf8 xfs code declares norm/normlen tuples on the stack for temporary use, so really this comes down to a matter of taste. And in that matter, I'd prefer that we keep the existing name abstaction and propagate it into the new code rather than the other way around.

(use xfs_logprint -t to determine that) xfs_repair -n ignores dirty logs, so the state on disk it may be reporting on can be inconsistent and that inconsistency is "fixed" by running log recovery. > Phase 1 - find and verify superblock... > - reporting progress in intervals of 15 minutes > Phase 2 - using internal log > - scan filesystem freespace and inode maps... > out-of-order bno btree record 83 (332943 42) block 27/4681 > out-of-order bno btree record 90 (322762 76) block 27/4681 > out-of-order bno btree record 91 (331903 125) block 27/4681 That implies that some updates to the btree block haven't occurred that compact out the old entries (that are now out of order). That can either occur due to writes going missing, or log recovery not being run.... Most of the issues could be caused by having a dirty log that needs recovery, so that is the first thing to check. Note that a non-dry-run xfs_repair will warn and abort if the log is dirty, unlike "xfs_repair -n".

=09=09=09=09=09=09=09Yesterday was a big day for us. And we really wanted i= t to be a great day for you.=09=09=09=09=09=09 =09=09=09=09=09=09=09But at the end of the day, we know that your experienc= e was less than pleasant. =09=09=09=09=09=09=09 =09=09=09=09=09=09=09We did not live up to the promises we made and for tha= t we are really and truly sorry.=20

=09=09=09=09=09=09=09 =09=09=09=09=09=09=09It took enormous effort from everyone at Flipkart, man= y months of preparation and pushing our capabilities and systems to the lim= it to be able to create this day. We were looking at fulfilling the dreams = of millions of Indian consumers through deals and offers we had painstaking= ly put together for months. =09=09=09=09=09=09=09

=09=09=09=09=09=09=09And though we saw unprecedented interest in our produc= ts and traffic like never before, we also realized that we were not adequat= ely prepared for the sheer scale of the event. We didn't source enough prod= ucts and deals in advance to cater to your requirements. To add to this, th= e load on our server led to intermittent outages, further impacting your sh= opping experience on our site. =09=09=09=09=09=09=09

=09=09=09=09=09=09=09An unprecedented 1.5 million people shopped at Flipkar= t yesterday. While we stand humbled by the sheer faith that such a large nu= mber of customers have shown in us, we are unhappy that we were unable to l= ive up to the expectations of millions more who wanted to buy from us yeste= rday. =09=09=09=09=09=09=09

=09=09=09=09=09=09=09And this is not acceptable to us. =09=09=09=09=09=09=09

=09=09=09=09=09=09=09Delighting you, and every single one of our customers,= is absolutely the top most priority for Flipkart and we have worked very h= ard over the last seven years to earn your trust. Yesterday, we failed that= trust. We have learnt some valuable lessons from this and have started wor= king doubly hard to address all the issues that cropped up during this sale= .=20 =09=09=09=09=09=09=09

=09=09=09=09=09=09=09Price Changes =09=09=09=09=09=09=09As we were preparing various deals and promotional pri= cing in the lead up to the sale, the pricing of several products got ?chang= ed to their non-discounted rates for a few hours?. We realise that this bre= aks the trust our customers have put in us. We are truly sorry for this and= will ensure that this never happens again. =09=09=09=09=09=09=09

=09=09=09=09=09=09=09Out-of-stock Issues =09=09=09=09=09=09=09We ran out of the stock for many products within a few= minutes (and in some cases, seconds) of the sale going live. For example, = most of our special deals were sold out as soon as they went live. We had e= nsured availability, anywhere from hundreds to a few lakh units for various= products, but it was nowhere near the actual demand. We promise to plan mu= ch better for future promotions and ensure that we minimise the out-of-stoc= k issues. =09=09=09=09=09=09=09

=20 =09=09=09=09=09=09=09Cancellations =09=09=09=09=09=09=09We had large number of people buying specific products= simultaneously. This led to some instances of an order getting over-booked= for a product that was sold out just a few seconds ago. We are working rou= nd-the-clock to ensure availability of additional units for these products = and will do our level best to ensure that we minimise any cancellations. =09=09=09=09=09=09=09

=20 =09=09=09=09=09=09=09Website Issues ?We realise that the shopping experience for many of you was frustrating du= e to errors and unavailability of the website at times. We had deployed nea= rly 5000 servers and had prepared for 20 times the traffic growth - but the= volume of traffic at different times of the day was much higher than this.= We are continuing to significantly scale up all our back end systems so th= at we do a much, much better job next time. =09=09=09=09=09=09=09

=20 =09=09=09=09=09=09=09Everything that we have achieved at Flipkart is purely= on the basis of our customer's trust and faith. This is why we come to wor= k each day and continue to remain extremely passionate about building the b= est possible customer experience for Indian consumers. We failed to live up= to this promise yesterday and would like to apologise once again to every = single customer for our failure. =09=09=09=09=09=09=09

=20 =09=09=09=09=09=09=09Thank you. =09=09=09=09=09=09=09

range operation is analogous to fallocate with the exception of converting the range to zeroes. E.g., it attempts to allocate zeroed blocks over the range specified by the caller. The XFS implementation kills all delalloc blocks currently over the aligned range, converts the range to allocated zero blocks (unwritten extents) and handles the partial pages at the ends of the range by sending writes through the pagecache. The current implementation suffers from several problems associated with inode size. If the aligned range covers an extending I/O, said I/O is discarded and an inode size update from a previous write never makes it to disk. Further, if an unaligned zero range extends beyond eof, the page write induced for the partial end page can itself increase the inode size, even if the zero range request is not supposed to update i_size (via KEEP_SIZE, similar to an fallocate beyond EOF). The latter behavior not only incorrectly increases the inode size, but can lead to stray delalloc blocks on the inode. Typically, post-eof preallocation blocks are either truncated on release or inode eviction or explicitly written to by xfs_zero_eof() on natural file size extension. If the inode size increases due to zero range, however, associated blocks leak into the address space having never been converted or mapped to pagecache pages. A direct I/O to such an uncovered range cannot convert the extent via writeback and will BUG(). For example: $ xfs_io -fc "pwrite 0 128k" -c "fzero -k 1m 54321" ... $ xfs_io -d -c "pread 128k 128k" If the entire delalloc extent happens to not have page coverage whatsoever (e.g., delalloc conversion couldn't find a large enough free space extent), even a full file writeback won't convert what's left of the extent and we'll assert on inode eviction. Rework xfs_zero_file_space() to avoid buffered I/O for partial pages. Align to blocksize rather than page size and use uncached buffers to zero partial blocks. Preallocate the outward block-aligned range to provide fallocate allocation semantics and convert the inward range to unwritten extents to zero the range.

Better to have QUOTA at the start, and TYPE in the name, so maybe: enum quota_types { QUOTA_TYPE_USR = 1 << USRQUOTA, QUOTA_TYPE_GRP = 1 << GRPQUOTA, QUOTA_TYPE_PRJ = 1 << PRJQUOTA, }; or maybe "enum quota_type_mask" or similar. I prefer named enums over #defines since this makes it more clear when declaring variables like "allowed_types" what valid values are instead of just "int" that someone might mistakenly set to USRQUOTA directly or something.

So there's no guarantee that this list will be in any way complete. Besides, we already have amore robust offline tool for generating such a list: $ man xfs_ncheck .... xfs_ncheck with no -i arguments generates an inode number and pathname list of all files on the given filesystem. ... It will also tell you when it fails to resolve a pathname or inode number due to corruption, so you have direct indication of what inodes and/or paths are broken.

If we don't modify the patch and continue with the uncached zeroing mechanism, we need to add a big warning about why we avoid the page cache for partial block zeroing. (i.e. to prevent ioend completions from updating inode size incorrectly and causing data corruption). > trace_xfs_zero_file_space(ip); > > - granularity = max_t(uint, 1 << mp->m_sb.sb_blocklog, PAGE_CACHE_SIZE); > + blksize = 1 << mp->m_sb.sb_blocklog; If we are now doing sub-page block manipulation, we have the issue with racing page faults failing to refault after the extent map has changed underneath partial pages.

Hence I'd split this into separate check+flush start, check+flush end branches that also check whether they are beyond EOF or in the EOF page we've already written. > + /* > + * Punch out the pagecache and delalloc extents in the range. > + * truncate_pagecache_range() handles partial page zeroing for us. > + */ > + truncate_pagecache_range(VFS_I(ip), offset, offset + len - 1); > + if (end_boundary > start_boundary) { > + xfs_ilock(ip, XFS_ILOCK_EXCL); > + error = xfs_bmap_punch_delalloc_range(ip, > + XFS_B_TO_FSBT(mp, start_boundary), > + XFS_B_TO_FSB(mp, > + end_boundary - start_boundary)); > + xfs_iunlock(ip, XFS_ILOCK_EXCL); > + } I see this if (end_boundary > start_boundary) check repeatedly - if this case is true, we are zeroing within a single block. If that block is within EOF, then all we need to do is call xfs_iozero() and we are done. Perhaps we should special case this right at the start of the function (similar to the special sub-single-block case in xfs_free_file_space()). > + > + /* > + * Now handle start and end sub-block zeroing.

Again, this does not need to happen if the start/end is beyond EOF, as a truncate up will completely zero the underlying blocks if that are allocated and in the written state. Hence I'm not sure that we actually need to do it this way. If we do this: if (isize needs update) filemap_write_and_wait_range(eof_block) truncate_pagecache_range(start, end) if (partial_and_within_eof(start_page)) filemap_write_and_wait_range(start_page) if (partial_and_within_eof(end_page)) filemap_write_and_wait_range(end_page) xfs_bmap_punch_delalloc_range(start, end) We should get the partial blocks correctly zeroed in the page cache, then the correctly zeroed pages written to disk, and then we punch out the delalloc blocks in the middle, thereby zeroing the in-memory extent tree to match the pagecache after the truncation we just did. > > - /* convert the blocks */ > + /* > + * Finally, preallocate the unaligned range and convert the block > + * aligned range to unwritten.

One call is all that is needed, and if we special case the (end_boundary > start_boundary) condition early on then there's only one range needed here.

How should we go about packaging this up for mainline inclusion? Additionally, I've been testing it with out application in and in the test environment we've a 30% reduction in average response time. We might be kind of a best case since we do a fair amount of CPU / IO bound work overlapped and this lets us skip the threadpool queue in a huge chunk of the cases.

OK, QUOTA_TYPE_USR etc. looks good. I'm not so sure about named enum. I'd be fine with named enum for USRQUOTA, GRPQUOTA, etc. - i.e., types which should have one of the named values but for a bitmask with arbitrary combinations of flags it looks confusing to me (although technically it would work).

The Linux kernel 3.2 logged many "soft lockup" messages which looks to be related to XFS: see kernel messages at the end of this email (it's only an extract of first messages, there are more later). I'm trying to find with google if the bug is known or not. "soft lockup" looks to be a "common" bug on Linux, but it's hard (for me) to check if existing bug reports are similar to our issue or not. And how can I check if it's an hardware issue or a Linux kernel (XFS?) issue? The following issues look similiar: - http://oss.sgi.com/archives/xfs/2013-06/msg00865.html : Centos, Linux kernel 2.6.32 This email mentions two bugzilla issues, probably the following ones, but I'm not allowed to see them :-/ https://bugzilla.redhat.com/show_bug.cgi?id=896224 https://bugzilla.redhat.com/show_bug.cgi?id=921961 - https://retrace.fedoraproject.org/faf/reports/98448/ : Fedora 18, Linux kernel 3.8 - https://bugs.centos.org/view.php?id=6287 : Linux 2.6.32 - https://lkml.org/lkml/2013/10/16/263 : RC version of Linux (3.12.0-rc1), maybe not reliable Some info about the server: - Dell PowerEdge R720xd/0X6H47 - Ubuntu 12.04 - Linux kernel 3.2.0-51-generic - Intel(R) Xeon(R) CPU E5-2665 0 @ 2.40GHz : 32 cores - 2 NUMA nodes There are 26 disks, HDD and SSD. All partitions used to store Swift objects are formatted with XFS, only a few system partitions are formatted as ext4 (and ext3 for /boot). There are 2 disk controllers: internal and a PCI Express controller. Victor Linux kernel messages: BUG: soft lockup - CPU#28 stuck for 22s!

That said, I'm not sure I see the benefit of adding code to detect scenarios that are already correctly handled. E.g., the pages don't need to be written back, so they won't be. It's also just as possible that offset and offset+len fall into the same page and we call writeback twice. I believe I originally had the start/end checks as separate checks and combined them at some point just to keep things simple (e.g., we have to do I/O anyways if one of the start of end is unaligned). I can break it back up into independent checks, but I'm hesitant to sprinkle more logic just to prevent things like calling filemap_write_and_wait_range() one time too many to no practical benefit. > > + /* > > + * Punch out the pagecache and delalloc extents in the range. > > + * truncate_pagecache_range() handles partial page zeroing for us. > > + */ > > + truncate_pagecache_range(VFS_I(ip), offset, offset + len - 1); > > + if (end_boundary > start_boundary) { > > + xfs_ilock(ip, XFS_ILOCK_EXCL); > > + error = xfs_bmap_punch_delalloc_range(ip, > > + XFS_B_TO_FSBT(mp, start_boundary), > > + XFS_B_TO_FSB(mp, > > + end_boundary - start_boundary)); > > + xfs_iunlock(ip, XFS_ILOCK_EXCL); > > + } > > I see this if (end_boundary > start_boundary) check repeatedly - if > this case is true, we are zeroing within a single block.

The 'if (end_boundary > start_boundary)' check means that the range covers one or more full blocks. We could add an optimization for the single/double block case as the original implementation had, but I'd prefer to do that as a separate patch considering the amount of testing I've done with this implementation so far. > > + > > + /* > > + * Now handle start and end sub-block zeroing.

I'll echo my previous sentiment with regard to keeping this simple. I'm not against follow-on optimizations to take better consideration of eof, to add an xfs_iozero() short-circuit, etc., but this took enough finagling and debugging to try and get right that I'd really prefer to keep this first version as simple as possible. > Hence I'm not sure that we actually need to do it this way.

If the pages happen to be cached and clean, we'd read what we expect until they are evicted and have to go back to disk. If they aren't cached, we'd still skip the on-disk update and probably detect it sooner. If they are cached and dirty, then perhaps that will work. So this is the reason for the current order: partial writeback, fix up pagecache, kill delalloc extents and update partial blocks on disk. I'm trying to document as much as possible in comments. Perhaps I should update the associated comment to make that bit more clear? FWIW, tracking down these kind of fsx issues is also why I'm particularly conservative about this patch at this point. I've played with various combinations of cache management and sub-block zeroing and had to track down numerous problems to try and get that part working. I've not been able to reproduce any corruption issues and I haven't seen a delalloc assert in ~450 some odd iterations of generic/269 on a setup that typically reproduces within 10-30 iterations. I did finally hit a getbmap delalloc assert, but I'm pretty sure I've seen that one for normal post-eof preallocation, e.g., not indicative of stray delalloc within eof. > > > > - /* convert the blocks */ > > + /* > > + * Finally, preallocate the unaligned range and convert the block > > + * aligned range to unwritten.

We want to make sure the partial/edge blocks are allocated but they cannot be converted to unwritten, so both calls are necessary. If you take a look back at v1, this basically reduces three alloc calls down to two in a manner that still does allocation linearly. Note that I did reproduce failures last night in generic/009 and xfs/242 that point out the length parameter in the first call is wrong. It passes the end offset rather than length. I expect for the second call to hit ENOSPC if the first one has. The reasoning here is that even though the allocation fails, we could still run though and convert some of the range up until we hit the point of allocation failure. Put another way, what I'd really like here is an xfs_bmap_convert_range() function that iterates similar to xfs_bmap_punch_delalloc_range() but converts all existing normal extents to unwritten without doing any block allocation. This means we could convert the range to zero value and put off preallocation (and the possibility of ENOSPC) to the absolute final step. That in turn means that even on ENOSPC, we'll have always zero-valued the range. That was also something I was considering looking into once this patch is merged. If the current logic is too ugly or I'm misjudging behavior, I could just wait until said helper exists and return immediately on allocation failure for now. Thoughts?

E.g., it attempts to allocate zeroed blocks over the range specified by the caller. The XFS implementation kills all delalloc blocks currently over the aligned range, converts the range to allocated zero blocks (unwritten extents) and handles the partial pages at the ends of the range by sending writes through the pagecache. The current implementation suffers from several problems associated with inode size. If the aligned range covers an extending I/O, said I/O is discarded and an inode size update from a previous write never makes it to disk. Further, if an unaligned zero range extends beyond eof, the page write induced for the partial end page can itself increase the inode size, even if the zero range request is not supposed to update i_size (via KEEP_SIZE, similar to an fallocate beyond EOF). The latter behavior not only incorrectly increases the inode size, but can lead to stray delalloc blocks on the inode. Typically, post-eof preallocation blocks are either truncated on release or inode eviction or explicitly written to by xfs_zero_eof() on natural file size extension. If the inode size increases due to zero range, however, associated blocks leak into the address space having never been converted or mapped to pagecache pages. A direct I/O to such an uncovered range cannot convert the extent via writeback and will BUG(). For example: $ xfs_io -fc "pwrite 0 128k" -c "fzero -k 1m 54321" ... $ xfs_io -d -c "pread 128k 128k" If the entire delalloc extent happens to not have page coverage whatsoever (e.g., delalloc conversion couldn't find a large enough free space extent), even a full file writeback won't convert what's left of the extent and we'll assert on inode eviction. Rework xfs_zero_file_space() to avoid buffered I/O for partial pages. Align to blocksize rather than page size and use uncached buffers to zero partial blocks. Preallocate the outward block-aligned range to provide fallocate allocation semantics and convert the inward range to unwritten extents to zero the range.

It's contending on the AIL lock, which is then causing contention on the next layer of locking above that (the iclog locks). There were lots of optimisations for AIL contention issues around the 3.2 timeframe as a result of the more widespread use of the recently introduced delayed logging functionality (which was made the default config in 3.2). I'm pretty sure these symptoms were a result of a bug that caused out-of-order items to be placed on the AIL, hence causing a walk of the AIL to find the insertion point for every item being added to the AIL rather than using the cursor to track the current insertion point and avoid repeated insertion point lookups. You best bet would be to upgrade to a more recent kernel rather than try to indentify and backport a bunch of fixes to an old kernel...

Then grab your favorite metrics tool that talks to graphite/influxdb (I like https://github.com/joelandman/sios-metrics for obvious reasons), and start collecting data. I'm told we have 800 threads writing to nearly as many files concurrently on a single XFS on a 12+2 spindle RAID6 LUN. Achieved data rate is currently ~300 MiB/s. Some of these are files are supposedly being written at a rate of only 32KiB every 2-3 seconds, while some (two) are ~50 MiB/s. I need to determine how many bytes we're writing to each of the low rate files, and how many files, to figure out RMW mitigation strategies. Out of the apparent 800 streams 700 are these low data rate suckers, one stream writing per file. Nary a stock RAID controller is going to be able to assemble full stripes out of these small slow writes. With a 768 KiB stripe that's what, 24 seconds to fill it at 2 seconds per 32 KiB IO? I've been playing with bcache for a few days but it actually drops throughput by about 30% no matter how I turn its knobs. Unless I can get Kent to respond to some of my questions bcache will be a dead end. I had high hopes for it, thinking it would turn these small random IOs into larger sequential writes. It may actually be doing so, but it's doing something else too, and badly. IO times go through the roof once bcache starts gobbling IOs, and throughput to the LUNs drops significantly even though bcache is writing 50-100 MIB/s to the SSD. Not sure what's causing that. >> Thanks, Stan >> >> _______________________________________________ xfs mailing list >> xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs >> > > _______________________________________________ > xfs mailing list > xfs@oss.sgi.com > http://oss.sgi.com/mailman/listinfo/xfs From victor.stinner@enovance.com Thu Oct 9 02:12:04 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay3.corp.sgi.com [198.149.34.15]) by oss.sgi.com (Postfix) with ESMTP id 566987F3F for ; Thu, 9 Oct 2014 02:12:04 -0500 (CDT) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay3.corp.sgi.com (Postfix) with ESMTP id E5750AC006 for ; Thu, 9 Oct 2014 00:12:00 -0700 (PDT) X-ASG-Debug-ID: 1412838714-04bdf0287862d00001-NocioJ Received: from smtp2-g21.free.fr (smtp2-g21.free.fr [212.27.42.2]) by cuda.sgi.com with ESMTP id I94Q4Xyhv1TpOaKr (version=TLSv1 cipher=AES256-SHA bits=256 verify=NO) for ; Thu, 09 Oct 2014 00:11:55 -0700 (PDT) X-Barracuda-Envelope-From: victor.stinner@enovance.com X-Barracuda-Apparent-Source-IP: 212.27.42.2 Received: from smithers.localnet (unknown [IPv6:2a01:e34:ec8d:4c70:f66d:4ff:fe37:2fab]) by smtp2-g21.free.fr (Postfix) with ESMTPS id 9B0644B010F; Thu, 9 Oct 2014 09:10:50 +0200 (CEST) From: Victor Stinner To: xfs@oss.sgi.com Cc: Dave Chinner Subject: Re: Can you help me to investiage a soft lockup?

I don't know the Linux kernel enough to feel confident to backport changes. So upgrading is the safest option. Eric Sandeen gave me the same advice. We will try to upgrade to Linux 3.13.

The code that is being removed here was for the case when you could have multiple filenames that match for a lookup, which was only possible when the ascii-ci bit was implemented as a mount option. The mount option was never merged, and the ascii-ci bit is implemented at mkfs and is not changeable over the lifetime of the filesystem. So today this code is not doing us much good. Maybe there are performance implications where you have a hash collision, but mostly I think it makes sense to remove this code from a maintainability standpoint. -Ben From bfoster@redhat.com Thu Oct 9 14:00:48 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id A3DDF7F3F for ; Thu, 9 Oct 2014 14:00:48 -0500 (CDT) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay2.corp.sgi.com (Postfix) with ESMTP id 74DEB304075 for ; Thu, 9 Oct 2014 12:00:45 -0700 (PDT) X-ASG-Debug-ID: 1412881243-04bdf0287710e470001-NocioJ Received: from mx1.redhat.com (mx1.redhat.com [209.132.183.28]) by cuda.sgi.com with ESMTP id l3PDVkF8Fl1HGSbz (version=TLSv1 cipher=AES256-SHA bits=256 verify=NO) for ; Thu, 09 Oct 2014 12:00:44 -0700 (PDT) X-Barracuda-Envelope-From: bfoster@redhat.com X-Barracuda-Apparent-Source-IP: 209.132.183.28 X-ASG-Whitelist: Client Received: from int-mx11.intmail.prod.int.phx2.redhat.com (int-mx11.intmail.prod.int.phx2.redhat.com [10.5.11.24]) by mx1.redhat.com (8.14.4/8.14.4) with ESMTP id s99J0hrV024649 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-GCM-SHA384 bits=256 verify=FAIL) for ; Thu, 9 Oct 2014 15:00:43 -0400 Received: from bfoster.bfoster ([10.18.41.237]) by int-mx11.intmail.prod.int.phx2.redhat.com (8.14.4/8.14.4) with ESMTP id s99J0hJu008029 for ; Thu, 9 Oct 2014 15:00:43 -0400 Received: by bfoster.bfoster (Postfix, from userid 1000) id ABDBE120064; Thu, 9 Oct 2014 15:00:41 -0400 (EDT) From: Brian Foster To: xfs@oss.sgi.com Subject: [PATCH] xfs: create zero range helper to convert existing extents to unwritten Date: Thu, 9 Oct 2014 15:00:41 -0400 X-ASG-Orig-Subj: [PATCH] xfs: create zero range helper to convert existing extents to unwritten Message-Id: <1412881241-34838-1-git-send-email-bfoster@redhat.com> X-Scanned-By: MIMEDefang 2.68 on 10.5.11.24 X-Barracuda-Connect: mx1.redhat.com[209.132.183.28] X-Barracuda-Start-Time: 1412881244 X-Barracuda-Encrypted: AES256-SHA X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 The zero range mechanism makes multiple xfs_alloc_file_space() calls to try convert as much of a range as possible to unwritten in the event of allocation failure. The problem is that the subsequent conversion call will progress no further than the first preallocate call if the latter happened to fail, because we have no ability to do extent conversion without preallocation. Create a helper to iterate a range of a bmap and convert all existing, normal extents to unwritten. Call the helper from xfs_zero_file_space() to accomplish the goal specified above. This allows zero range to put off preallocation to the final step and thus ensures the range is zero valued before any significant preallocation is attemped.

This applies on top of v3: http://oss.sgi.com/archives/xfs/2014-10/msg00149.html Lightly tested, but I'm throwing some workloads at it now and so far, so good. Thoughts appreciated.

Yes, I know what the code did - it allowed us to support mixed case ascii-ci filesystems. All you've said is "if we remove mixed case support the code is cleaner" but not addressed the issue at hand. I'll try asking the same question a different way: if we keep this code, will it work for mixed case unicode filesystem or do we have to re-implement mixed case matching differently?

A good place to start might be here: http://www.brendangregg.com/perf.html Specifically his iosnoop tool is a simple template that you can customise to your own needs: http://www.brendangregg.com/blog/2014-07-16/iosnoop-for-linux.html http://www.brendangregg.com/blog/2014-07-23/linux-iosnoop-latency-heat-maps.html Cheers, Dave. -- Dave Chinner david@fromorbit.com From david@fromorbit.com Thu Oct 9 16:13:45 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id 53D687F3F for ; Thu, 9 Oct 2014 16:13:45 -0500 (CDT) Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by relay2.corp.sgi.com (Postfix) with ESMTP id 32E28304070 for ; Thu, 9 Oct 2014 14:13:45 -0700 (PDT) X-ASG-Debug-ID: 1412889222-04cbb018ab163b90001-NocioJ Received: from ipmail06.adl2.internode.on.net (ipmail06.adl2.internode.on.net [150.101.137.129]) by cuda.sgi.com with ESMTP id arHTv5PV1Kymjjdh for ; Thu, 09 Oct 2014 14:13:43 -0700 (PDT) X-Barracuda-Envelope-From: david@fromorbit.com X-Barracuda-Apparent-Source-IP: 150.101.137.129 X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: AhMcADr5NlR5LODnPGdsb2JhbABggw5TWII2tS0GkzCBXYVqBAICgQgXAQYBAQEBODmEAwEBAQMBOhwjBQsIAxgJJQ8FJQMHGhOINgcOwn0BEwQYhgiKJAeDLYEeBZY7hw+BL5BlhWgggW0pL4JKAQEB Received: from ppp121-44-224-231.lns20.syd7.internode.on.net (HELO dastard) ([121.44.224.231]) by ipmail06.adl2.internode.on.net with ESMTP; 10 Oct 2014 07:43:40 +1030 Received: from dave by dastard with local (Exim 4.80) (envelope-from ) id 1XcL1n-0003y6-EI; Fri, 10 Oct 2014 08:13:39 +1100 Date: Fri, 10 Oct 2014 08:13:39 +1100 From: Dave Chinner To: Stan Hoeppner Cc: xfs@oss.sgi.com Subject: Re: gather write metrics on multiple files Message-ID: <20141009211339.GD4376@dastard> X-ASG-Orig-Subj: Re: gather write metrics on multiple files References: <543611CF.6030904@hardwarefreak.com> <543613E7.70508@gmail.com> <54361C04.5090404@hardwarefreak.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <54361C04.5090404@hardwarefreak.com> User-Agent: Mutt/1.5.21 (2010-09-15) X-Barracuda-Connect: ipmail06.adl2.internode.on.net[150.101.137.129] X-Barracuda-Start-Time: 1412889222 X-Barracuda-URL: http://192.48.176.25:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.10387 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On Thu, Oct 09, 2014 at 12:24:20AM -0500, Stan Hoeppner wrote: > On 10/08/2014 11:49 PM, Joe Landman wrote: > > On 10/09/2014 12:40 AM, Stan Hoeppner wrote: > >> Does anyone know of a utility that can track writes to files in > >> an XFS directory tree, or filesystem wide for that matter, and > >> gather filesystem blocks written per second data, or simply > >> KiB/s, etc?

Most don't have the memory available to track that many active write streams, and those that do probably can't proritise writeback sanely given how slowly most cachelines would be touched. The fast writers would simply tune over the slower writer caches way too quickly. Perhaps you need to change the application to make the slow writers buffer stripe sized writes in memory and flush them 768k at a time... > I've been playing with bcache for a few days but it actually drops > throughput by about 30% no matter how I turn its knobs.

Just started earlier today. Turns out the buffer sizes and buffer count are configurable, not hard coded, at least in the test harness. AIUI the actual application creates variable sized buffers on the fly. In which case the test harness doesn't accurately simulate the real app. So the numbers we might achieve optimizing the harness may not reflect reality, same for the storage subsystem tweaks for that matter. Which brings up a whole other set of questions regarding what we're actually doing.... >> I've been playing with bcache for a few days but it actually drops >> throughput by about 30% no matter how I turn its knobs.

Initially it appears it is optimized for read caching as bcache seems to be. I've tested bcache on 3.12 and 3.17 and its write throughput on the latter is even worse, both being ~30-40 lower than native. Latency goes through the roof, and iostat shows the distribution across the LUNs is horribly uneven. Atop that, running iotop at 1 second intervals shows no IO on one LUN or the other for 1-2 seconds at a time. And when both do show IO the rates are up and down all over the place. Runnig native IO the rates are constant and the spread between LUNs in 2-3%. Not sure what the problem is here with bcache, but it certainly doesn't behave as I expected it would. It's really quite horrible for this workload. And that's when attempting to push only ~360 MB/s per LUN. Kent doesn't seem interested in assisting thus far. Which is a shame. Having bcache running on hundreds of systems of this caliber would be a feather in his cap, and a validation of his work. Natively we're currently achieving about 2.3 GB/s write throughput across 14 RAID6 LUNs (12+2) on two controllers in an active-active multipath setup. If bcache was performing how I'd think it should, with the right number of SSDs I'd think we could be knocking on the 3 GB/s door.

Hi Dave,
i do and have to use Option -L but it was with success. I reboot the system and tried to copy the files again and after a view hundreds of MB the failure occures again. A actually do xfs_repair -L again, but i think the problem still exists. Any idea where the problem cames from and what i could do? I will now check the smart values.

Looks like a handful of corrupted inode blocks, with the main problem being that the inodes 3469995058-3469995060 (i.e. 3 inodes) do not have the corect magic numbers in them. the rest of the inodes in that chunk are corrupt in some way, too, so it would seem that there's been some kind of write error to these inodes. xfs_repair should fix this problems without issues.

When function xlog_cil_push_now called in xlog_cil_force_lsn, and the xlog_cil_push run in workqueue just reaches the= point for setting cil->xc_current_sequence, the xlog_cil_force_lsn got the lock and check the "sequence =3D=3D cil->xc_current_sequence && !list_empty(&cil->xc_cil)" for restart. The statement "sequence =3D=3D cil->xc_current_sequence" is true, but the cil->xc_cil is empty according to the xlog_cil_push removed the items in cil->xc_cil without lock protectionl. So the function xlog_cil_force_lsn will return NULLCOMMITLSN, which means the cil log for current sequence will not be submitted to disk. And if there is no more operations(for example, when unmount fs, this situation happened in xfs_unmountfs->xfs_log_sbcount->xfs_trans_commit), the xfs will hang up.

Hi Emmanuel,
i acknowledge your answer. i think its an hardware problem. i looked now for over 4 houres to find out how i match ata14. with the disk, but no script or tool like lshw shows the correct match. I also use an extra sata3 controller with Marvel 88SE9230 Chip on it. My Kernel is from stable wheezy 3.2.0-4-amd64 and i think its an bug for this card / controller. I know this is not longer an xfs Problem, but perhabs someone can help to solve this problem.

That means that xlog_cil_force_lsn() should see the ctx either on the committing list and wait for it (commit_lsn != NULL), or not on the committing list at all. If it's not on the committing list yet, xlog_cil_push() won't have either drained the ctx or updated the sequence number, as it adds to the committing list first and that requires the push lock (which xlog_cil_force_lsn() holds and doesn't release until after the restart check). Am I missing something? Do you reproduce a problem with the latest tree that includes the above patch?

The problem with this is that it can delay work that is scheduled for immediate execution, such as the work from sync_inodes_sb(). This can happen since mod_delayed_work() can now steal work from a work_queue. This fixes the problem by using queue_delayed_work() instead. This is a regression caused by 839a8e8660b6 "writeback: replace custom worker pool implementation with unbound workqueue". The reason that this causes a problem is that laptop-mode will change the delay, dirty_writeback_centisecs, to 60000 (10 minutes) by default. In the case that bdi_wakeup_thread_delayed() races with sync_inodes_sb(), sync will be stopped for 10 minutes and trigger a hung task. Even if dirty_writeback_centisecs is not long enough to cause a hung task, we still don't want to delay sync for that long. We fix the problem by using queue_delayed_work() when we want to schedule writeback sometime in future. This function doesn't change the timer if it is already armed. For the same reason, we also change bdi_writeback_workfn() to immediately queue the work again in the case that the work_list is not empty. The same problem can happen if the sync work is run on the rescue worker.

The patchset fixes XFS and ext4. I've checked and btrfs doesn't need fixing because it doesn't support blocksize < pagesize. If that's ever going to change btrfs will likely need a similar treatment. ocfs2, ext2, ext3 are OK since they happily allocate blocks during writeback. For other filesystems like gfs2, ubifs, nilfs, ceph,... I'm not sure whether they support blocksize < pagesize at all. Interesting is also NFS which may care but I don't understand its ->page_mkwrite() handler good enough to judge. Changes since v1: - changed helper function name and moved it to mm/truncate.c - I originally thought we can make the helper function update i_size to simplify the interface but it's actually impossible due to generic_write_end() lock ordering constraints. - used round_up() instead of ALIGN() - taught truncate_setsize() to use the helper function Honza From jack@suse.cz Fri Oct 10 09:24:08 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id 7D4ED7F4E for ; Fri, 10 Oct 2014 09:24:08 -0500 (CDT) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay1.corp.sgi.com (Postfix) with ESMTP id 4EC778F8059 for ; Fri, 10 Oct 2014 07:24:08 -0700 (PDT) X-ASG-Debug-ID: 1412951045-04bdf028792a5570001-NocioJ Received: from mx2.suse.de (cantor2.suse.de [195.135.220.15]) by cuda.sgi.com with ESMTP id VfpcUWUA9DXUAEpx (version=TLSv1 cipher=AES256-SHA bits=256 verify=NO) for ; Fri, 10 Oct 2014 07:24:06 -0700 (PDT) X-Barracuda-Envelope-From: jack@suse.cz X-Barracuda-Apparent-Source-IP: 195.135.220.15 Received: from relay1.suse.de (charybdis-ext.suse.de [195.135.220.254]) by mx2.suse.de (Postfix) with ESMTP id 2E58FADD7; Fri, 10 Oct 2014 14:24:03 +0000 (UTC) Received: by quack.suse.cz (Postfix, from userid 1000) id 92B4F81FCA; Fri, 10 Oct 2014 16:24:01 +0200 (CEST) From: Jan Kara To: linux-fsdevel@vger.kernel.org Cc: linux-ext4@vger.kernel.org, Dave Chinner , xfs@oss.sgi.com, cluster-devel@redhat.com, Steven Whitehouse , Mark Fasheh , Joel Becker , ocfs2-devel@oss.oracle.com, reiserfs-devel@vger.kernel.org, Jeff Mahoney , Dave Kleikamp , jfs-discussion@lists.sourceforge.net, tytso@mit.edu, viro@zeniv.linux.org.uk, Jan Kara Subject: [PATCH] ext4: Speedup WB_SYNC_ALL pass Date: Fri, 10 Oct 2014 16:23:20 +0200 X-ASG-Orig-Subj: [PATCH] ext4: Speedup WB_SYNC_ALL pass Message-Id: <1412951028-4085-16-git-send-email-jack@suse.cz> X-Mailer: git-send-email 1.8.1.4 In-Reply-To: <1412951028-4085-1-git-send-email-jack@suse.cz> References: <1412951028-4085-1-git-send-email-jack@suse.cz> X-Barracuda-Connect: cantor2.suse.de[195.135.220.15] X-Barracuda-Start-Time: 1412951046 X-Barracuda-Encrypted: AES256-SHA X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests=BSF_SC0_MISMATCH_TO X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.10411 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.00 BSF_SC0_MISMATCH_TO Envelope rcpt doesn't match header When doing filesystem wide sync, there's no need to force transaction commit (or synchronously write inode buffer) separately for each inode because ext4_sync_fs() takes care of forcing commit at the end (VFS takes care of flushing buffer cache, respectively).

So when flusher thread comes later when filesystem is frozen, it tries to write back dirty pages, ext3_journalled_writepage() tries to start a transaction and hangs waiting for frozen fs causing a deadlock because a holder of s_umount semaphore may be waiting for flusher thread to complete. The fix is luckily relatively easy. We don't have to start a transaction in ext3_journalled_writepage() when a page is just dirty (and doesn't have PageChecked set) because in that case all buffers should be already mapped (mapping must happen before writing a buffer to the journal) and it is enough to write them out. This optimization also solves the deadlock because block_write_full_page() will just find out there's no buffer to write and do nothing.

The purpose is to avoid an unnecessary IPI. Let's take an example. My test box has cpu 0-7, one socket. Say request is added from CPU 1, blk_complete_request() occurs at CPU 7. Without the reverted patch, softirq will be done at CPU 7. With it, an IPI will be directed to CPU 0, and softirq will be done at CPU 0. In this case, doing softirq at CPU 0 and CPU 7 have no difference from cache sharing point view and we can avoid an ipi if doing it in CPU 7. An immediate concern is this is just like QUEUE_FLAG_SAME_FORCE, but actually not. blk_complete_request() is running in interrupt handler, and currently I/O controller doesn't support multiple interrupts (I checked several LSI cards and AHCI), so only one CPU can run blk_complete_request(). This is still quite different as QUEUE_FLAG_SAME_FORCE. Since only one CPU runs softirq, the only difference with below patch is softirq not always runs at the first CPU of a group.

This is caused by the following race of two ext4_xattr_release_block() calls: CPU1 CPU2 ext4_xattr_release_block() ext4_xattr_release_block() lock_buffer(bh); /* False */ if (BHDR(bh)->h_refcount == cpu_to_le32(1)) } else { le32_add_cpu(&BHDR(bh)->h_refcount, -1); unlock_buffer(bh); lock_buffer(bh); /* True */ if (BHDR(bh)->h_refcount == cpu_to_le32(1)) get_bh(bh); ext4_free_blocks() ... jbd2_journal_forget() jbd2_journal_unfile_buffer() -> JH is gone error = ext4_handle_dirty_xattr_block(handle, inode, bh); -> triggers the warning We fix the problem by moving ext4_handle_dirty_xattr_block() under the buffer lock. Sadly this cannot be done in nojournal mode as that function can call sync_dirty_buffer() which would deadlock.

Commit 85816794240b ("fanotify: Fix use after free for permission events") introduced a double free issue for permission events which are pending in group's notification queue while group is being destroyed. These events are freed from fanotify_handle_event() but they are not removed from groups notification queue and thus they get freed again from fsnotify_flush_notify(). Fix the problem by removing permission events from notification queue before freeing them if we skip processing access response.

This was because ncp_rmdir checked to see if a dentry could be unhashed before allowing it to be removed. Since 1d2ef5901483004d74947bbf78d5146c24038fe7 introduced a change that incremented dentry->d_count causing it to always be greater than 1 unhash would always fail. Thus causing the error path in ncp_rmdir to always be taken. Removing this error path is safe as unhashing is still accomplished by calls to dput from vfs_rmdir.

This is done in the context of the flusher thread, and hence completely ties up the flusher thread for the backing device until all the dirty inodes have been synced. On filesystems that are dirtying inodes constantly and quickly, this means the flusher thread can be tied up for minutes per sync call and hence badly affect system level write IO performance as the page cache cannot be cleaned quickly. We already have a wait loop for IO completion for sync(2), so cut this out of the flusher thread and delegate it to wait_sb_inodes(). Hence we can do rapid IO submission, and then wait for it all to complete.

Doing writeback on lots of little files causes terrible IOPS storms because of the per-mapping writeback plugging we do. This essentially causes imeediate dispatch of IO for each mapping, regardless of the context in which writeback is occurring. IOWs, running a concurrent write-lots-of-small 4k files using fsmark on XFS results in a huge number of IOPS being issued for data writes. Metadata writes are sorted and plugged at a high level by XFS, so aggregate nicely into large IOs. However, data writeback IOs are dispatched in individual 4k IOs - even when the blocks of two consecutively written files are adjacent - because the underlying block device is fast enough not to congest on such IO. This behaviour is not SSD related - anything with hardware caches is going to see the same benefits as the IO rates are limited only by how fast adjacent IOs can be sent to the hardware caches for aggregation. Hence the speed of the physical device is irrelevant to this common writeback workload (happens every time you untar a tarball!) - performance is limited by the overhead of dispatching individual IOs from a single writeback thread.

However if we are rescheduled, we are guaranteed to run on an online cpu so we can easily just get the cpu id in can_use_console(). We can lose a bit of performance when we enable interrupts in vprintk_emit() and then disable them again in console_unlock() but OTOH it can somewhat reduce interrupt latency caused by console_unlock(). We differ from (reverted) commit 939f04bec1a4 in that we avoid calling console_unlock() from vprintk_emit() with lockdep enabled as that has unveiled quite some bugs leading to system freezes during boot (e.g. https://lkml.org/lkml/2014/5/30/242, https://lkml.org/lkml/2014/6/28/521).

This allows a filesystem to return a page fault if there is not enough space available, user exceeds quota or similar problem happens, rather than silently discarding data later when writepage is called. However VFS fails to call ->page_mkwrite() in all the cases where filesystems need it when blocksize < pagesize. For example when blocksize = 1024, pagesize = 4096 the following is problematic: ftruncate(fd, 0); pwrite(fd, buf, 1024, 0); map = mmap(NULL, 1024, PROT_WRITE, MAP_SHARED, fd, 0); map[0] = 'a'; ----> page_mkwrite() for index 0 is called ftruncate(fd, 10000); /* or even pwrite(fd, buf, 1, 10000) */ mremap(map, 1024, 10000, 0); map[4095] = 'a'; ----> no page_mkwrite() called At the moment ->page_mkwrite() is called, filesystem can allocate only one block for the page because i_size == 1024. Otherwise it would create blocks beyond i_size which is generally undesirable. But later at ->writepage() time, we also need to store data at offset 4095 but we don't have block allocated for it. This patch introduces a helper function filesystems can use to have ->page_mkwrite() called at all the necessary moments.

That makes sense at the first sight (and definitely is a valid implementation of the spec) but at the second sight it isn't very useful. If anyone bothers with looking for holes / data, he should be better told we don't really know so that he can fall back to his chosen backup strategy (think of e.g. cp(1)). This is a userspace API change however the kernel interface is there only for two years so hopefully userspace is still prepared to handle EINVAL return value.

But it makes the old rq_affinity = 1 not work any more. The root cause is that if the 'cpu' and 'req->cpu' is in the same group and cpu != req->cpu, ccpu will be the same as group_cpu, so the completion will be excuted in the 'cpu' not 'group_cpu'. This patch fix problem by simpling removing group_cpu and the codes are more explicit now. If ccpu == cpu, we complete in cpu, otherwise we raise_blk_irq to ccpu.

This can happen because even though bdi_unregister() cancels all pending flushing work, nothing really prevents new ones from being queued from balance_dirty_pages() or other places. Fix the problem by clearing BDI_registered bit in bdi_unregister() and checking it before scheduling of any flushing work.

I've checked and that doesn't seem to happen anywhere else in the kernel. So let's move printk() from under that lock. As a side note this problem has existed for a long time but it was uncovered by my patch resulting in extended lockdep coverage of printk code.

Thus filesystems which don't need it save 2 pointers in their inodes (would be 3 after we add project quota support into generic quota). I have patches to move inode->i_data.private_list into filesystem private part of the inode which is going to save another 2 pointers using the same mechanism. However I didn't want to mix those in. The patch series also contains a change to quotactl so that each filesystem can set quota types it supports. This is in the end unrelated change (originally it was necessary for i_dquot moving but in the end I changed things so that it's not anymore). I can move that into a separate series but I was somewhat reluctant to do that since that would mean another 6 one-line patches to the same files we are changing here... If noone has any objections, I'd like to queue this series into my tree for the next merge window. For that I'd prefer to get acks from affected fs maintainers (the changes are pretty trivial and I don't feel it's a must but still I'd prefer fs maintainers to ack they are aware of the changes). Honza Changes since v1: * Inode field names are now named enum * Quota type masks now have names like QTYPE_MASK_{USR|GRP|PRJ} instead of opencoding shifts.

Thus all the other filesystems are just wasting memory with these fields. On the other hand it isn't simple to just move these fields to filesystem specific part of inode because there is generic code which needs to peek into the fields and it is cumbersome to provide helpers into which fs has to stuff the field it is storing elsewhere. We create a simple infrastructure which allows for optional inode fields stored in the fs-specific part of the inode. Accessing these fields has a slightly worse performance as we have to lookup their offset in the offset table stored in the superblock but in most cases this is acceptable.

I've had a neil poulton network space for some time now - it freaked out a while ago and I managed to rig it up to a Ubuntu liveCD via a SATA dock and rescue the files. This has now happened again - the drive would not get out of a cycle and was not spinning properly. Bring out the dock and liveCD (this time Knoppix). All good. This time however as I eagerly copied files to another drive (a USB powered lacie rugged thing) and left it overnight i woke up to an error. I was copying around 500GB in a few diffferent chunks. The first error it reported was I think error 15? mount structure needs cleaning... I then tried with a Ubuntu liveCD - same error. This is maybe where I made a bit of an error of my own. In an attempt to shake it out of it's stupor I 'stupidly' plugged it into windows and opened up the disk utility (sorry I'm generally mac based) and deleted in total 5 partitions (3x8mb, 1x250odd mb & 1x600mbish partition) This left the partition that I assumed contained all my files: a 920GB partition. Tried to look at it again on Linux & (both Knoppix & Ubuntu) and the error message had changed slightly. It now reads: "Error mounting /dev/sdc2 at /media/ubuntu/e8b90eb2-8718-4964-939d-8a2b899b68bd: Command-line `mount -t "xfs" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdc2" "/media/ubuntu/e8b90eb2-8718-4964-939d-8a2b899b68bd"' exited with non-zero exit status 32: mount: Structure needs cleaning" This drive has all my audio and video stored on it! Any help to move me toward a solution would be much appreciated! Thanks for your time...

We've been seeing this a lot over the past few kernel releases and there have been a variety of fixes in error paths and such so it's hard to say precisely what might be causing this. Some examples: aad3f375 xfs: xfs_vm_write_end truncates too much on failure 72ab70a1 xfs: write failure beyond EOF truncates too much data 4ab9ed57 xfs: kill buffers over failed write ranges properly It looks like those are in the stable tree as of 3.15, so you could give that a try and see if it helps. Otherwise, can you post xfs_info for the filesytem? Do you have particular workloads or sequences of operations that tend to reproduce this?

I suppose that shouldn't effect things either way, but I'm not really sure what the disk utility might do. It might be worth checking whether 'file -s ' still identifies the partition as an XFS filesystem..? Beyond that, I'd suggest to capture and post the logs of the failed mount and perhaps the output of 'xfs_repair -n .' This will attempt a dry-run (e.g., no modifications) check and repair of the filesystem. Brian > This drive has all my audio and video stored on it!

The loop in xfs_inumbers() needs to fill the user-supplied buffers, and iterates via xfs_btree_increment, reading new ags as needed. But the first time through the loop, if xfs_btree_increment() succeeds, we continue, which triggers the ++agno at the bottom of the loop, and we skip to soon to the next ag - without the proper setup under next_ag to read the next ag. Fix this by removing the agno increment from the loop conditional, and only increment agno if we have actually hit the code under the next_ag: target. Cc: stable@vger.kernel.org Signed-off-by: Eric Sandeen --- p.s. it's alarming that apparently no test in the dump group detects this problem! I'll look into it.

This "array of offsets" approach is asking for trouble. Please, don't go there - playing that way with type safety is a bad idea.

I'll look into it. The dump tests must not create more than an inode chunks worth of files in each AG.

What we actually have it two loops in one: do { while (inobt records exist) { /* format record */ } } while (++agno < mp->m_sb.sb_agcount) But the inner loop is not implemented as a loop, it's implemented split across two iterations on the outer loop (i.e. increment in one iteration, formatting in the next). Hence the bug. The code should really be further factored to: do { /* read agi */ error = xfs_ialloc_read_agi(agno, &agbp) if (error) break; error = xfs_inumbers_ag(...); if (error) break; xfs_buf_relse(agbp); agino = 0; agno++; } while (agno < mp->m_sb.sb_agcount) So that the AG is traversed and records processed within it's own cursor-based traversal loop inside xfs_inumbers_ag(), not split across the outer ag scope loop. I'll take the first patch right away, but can you follow up with the above refactoring, Eric?

The loop in xfs_inumbers() needs to fill the user-supplied buffers, and iterates via xfs_btree_increment, reading new ags as needed. But the first time through the loop, if xfs_btree_increment() succeeds, we continue, which triggers the ++agno at the bottom of the loop, and we skip to soon to the next ag - without the proper setup under next_ag to read the next ag. Fix this by removing the agno increment from the loop conditional, and only increment agno if we have actually hit the code under the next_ag: target.

The changes outlined in the tag description include everything that is not in your tree, but I has a question about that because there are commits in the branch that are already in your tree. i.e. I have generated this pull-req from the base tree I've been working on (3.17-rc2) but there have already been commits merged into a more recent upstream tree (3.17-rc4) in this tree. When I generate the pull request from the underlying 3.17-rc2 branch, it includes all those commits, both in the summary and the diffstat. If I base the pull request off 3.17, the base commit is the last one that was merged into your tree, and the diffstat and commit list reflect that. So my question is this: Which tree should I generate the pull request from? I flipped a coin an generated this one from 3.17-rc2, but if you'd prefer to see just the commits/diffstat that aren't in your tree, let me know and I'll do it differently next time.... -Dave.

This is normal and expected for stuff that has gotten into my tree other ways (ie bugfixes that were cherrypicked to be backported from development trees etc). I'm used to it, and while I hope people minimize it (not only because of multiple commits showing up with the same patch, but because it can easily cause stupid merge conflicts because the development tree then made further changes on top of the same patch), it's also very much considered "normal development". That said, when there are actual *common* commits as in your case (as opposed to cherrypicked commits that generate duplicate commits with the same patch), I would generally suggest you just let "git merge-base" figure it all out from my latest tree. That way it takes into account the stuff that you sent earlier on its own. But this is not a big deal. > So my question is this: Which tree should I generate the pull > request from? I flipped a coin an generated this one from 3.17-rc2, > but if you'd prefer to see just the commits/diffstat that aren't in > your tree, let me know and I'll do it differently next time.... Normally, I'd suggest the easiest way to handle things is to have a "linus" branch that tracks my upstream, and then just generate the pull request off that. Git will figure out the latest merge base and just do the right thing, and you don't need to really think about where you forked things off, and which parts you have already sent to me. As mentioned, even then the diffstat doesn't always end up being exactly right, because the history with partially merged branches, and with potential cherry-picked commits. So I am not surprised or upset if the diffstat doesn't always match, it happens quite commonly. I go on a rant when that i sdue to bad development practices, but I don't see anything like that in your tree. Some people avoid this by actually generating a test-merge (to warn me about upcoming conflicts etc), and then generate the diffstat from that test merge instead of just using the plain "git diff" in the git-pull-request helper scripts. Whatever works. This is not a huge deal, exactly because it's "normal development" (unlike the back-merges issue). And in this case, it looks like you don't even have cherry-picks, but just shared common branches, some of which you sent earlier. It looks like the diffstat if you just use my current tree as the other point of the git merge-base is correct, although I haven't actually done the merge itself yet (still waiting for the build for the previous merge to finish).

It's advisable to try to create an image of the disk on another one, and work for this image, because this disk will probably die any time now.

E.g., it attempts to allocate zeroed blocks over the range specified by the caller. The XFS implementation kills all delalloc blocks currently over the aligned range, converts the range to allocated zero blocks (unwritten extents) and handles the partial pages at the ends of the range by sending writes through the pagecache. The current implementation suffers from several problems associated with inode size. If the aligned range covers an extending I/O, said I/O is discarded and an inode size update from a previous write never makes it to disk. Further, if an unaligned zero range extends beyond eof, the page write induced for the partial end page can itself increase the inode size, even if the zero range request is not supposed to update i_size (via KEEP_SIZE, similar to an fallocate beyond EOF). The latter behavior not only incorrectly increases the inode size, but can lead to stray delalloc blocks on the inode. Typically, post-eof preallocation blocks are either truncated on release or inode eviction or explicitly written to by xfs_zero_eof() on natural file size extension. If the inode size increases due to zero range, however, associated blocks leak into the address space having never been converted or mapped to pagecache pages. A direct I/O to such an uncovered range cannot convert the extent via writeback and will BUG(). For example: $ xfs_io -fc "pwrite 0 128k" -c "fzero -k 1m 54321" ... $ xfs_io -d -c "pread 128k 128k" If the entire delalloc extent happens to not have page coverage whatsoever (e.g., delalloc conversion couldn't find a large enough free space extent), even a full file writeback won't convert what's left of the extent and we'll assert on inode eviction. Rework xfs_zero_file_space() to avoid buffered I/O for partial pages. Use the existing hole punch and prealloc mechanisms as primitives for zero range. We punch out the pagecache beforehand to eliminate unnecessary writeback. The hole punch mechanism handles partial block zeroing for us and facilitates the use of a single prealloc call over the entire range, which increases the odds of contiguous allocation. Signed-off-by: Brian Foster --- This is v4, but effectively an alternate implementation to v3 that reduces zero range to a hole punch and preallocate operation. I originally reproduced a hang with v3 + my unwritten conversion helper patch that I thought somehow related to said helper, but I have seen what appears to be the same thing with this patch after a couple hundred cycles of generic/269. That leads me to believe that there is a more general problem perhaps related to the increased extent manipulation going on in either implementation (whether for conversion or removal). I don't reproduce such a failure with focused hole punch testing on tot, but I do reproduce other assert failures that I suspect just mask the ability to reproduce this one. In short, all three of these configurations pass basic correctness tests for me. v3 has been the most reliable in stress tests. v3+unwritten conversion and v4 seem to reproduce this hang after a while. v4 is probably the most simple implementation of the three.

Hi Emmanuel, so that should be what you = asked for? I did a reset in terminal and tried the dmesg, so I hope this d= idn't wipe any data on the failed mount which I had completed before. I'm = about to try mouning as read only - fingers crossed!
Cheers,
Tom

Most probably disk is badly damaged, dead= or dying. It's advisable to
try to create an image of the disk on anot= her one, and work for this
image, because this disk will probably die a= ny time now. It's no use
trying to repair a filesystem on a bad drive, = which is the cause of the
errors from the beginning.

If all you= care is to get your files back, just try to mount the volume
in read-o= nly, non-recovery mode :

mount -o ro,norecovery /dev/sdc2 /tmp/moun= t

Then proceed by copying whatever you can get. Consider that any f= ile
that gives an error is lost.

The other option is Kroll Ontra= ck or similar services, of course.

OK, that's exactly what I would have done if the coin flip landed the other way.

That's good to know - I'm trying to keep the topic branches as stable as possible so you can see when they were first pushed into the tree, if/when fixes are appended to them and the dependencies between them so bisects won't break. If you do see something wrong or dodgy, just yell. ;) > Some people avoid this by actually generating a test-merge (to warn me > about upcoming conflicts etc), and then generate the diffstat from > that test merge instead of just using the plain "git diff" in the > git-pull-request helper scripts. Whatever works. This is not a huge > deal, exactly because it's "normal development" (unlike the > back-merges issue). *nod* Definitely "normal development" - I do that "test merge" as part of my day-to-day workflow. My test tree (i.e. what I point overnight xfstests runs at) is your TOT + the current XFS for-next + any patch sets I'm reviewing, testing and/or developing.... Thanks for the info, Linus.

THose are IO errors, and the "Unrecovered read error" and "critical medium error" messages indicate that the drive has lost the data in those sectors permanently. i.e. the disk has physically failed and it needs to be replaced. As Emmanuel has already mentioned, the best you can probably do at this point mount the filesystem "-o ro,norecover" and copy everything you can off onto a new drive....

You're now into disaster recovery territory. Use ddrescue to image the filesystem, then something like photorec or some other data recovery tool to scrape the image for intact files that otherwise couldn't be pulled from the mounted filesystem.

The metadata information from the drive may be inaccurate because the log is corrupted. Then some folder data may have been lost and prevent you from recovering the files that are in some folders. After you're done copying all files you can from the disk, you can try to make a mirror image on another drive at least as big as this one, and run xfs_repair on the image. After that you could eventually get more data back (it depends upon the extent of the damage to the actual data and file structure). To copy the disk on another one, you can use ddrescue or dd with "noerror" option. --=20 ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | | +33 1 78 94 84 02 ------------------------------------------------------------------------ From bfoster@redhat.com Tue Oct 14 06:38:11 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay3.corp.sgi.com [198.149.34.15]) by oss.sgi.com (Postfix) with ESMTP id 204D37F3F for ; Tue, 14 Oct 2014 06:38:11 -0500 (CDT) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay3.corp.sgi.com (Postfix) with ESMTP id BE64BAC010 for ; Tue, 14 Oct 2014 04:38:10 -0700 (PDT) X-ASG-Debug-ID: 1413286687-04bdf0287637fab0001-NocioJ Received: from mx1.redhat.com (mx1.redhat.com [209.132.183.28]) by cuda.sgi.com with ESMTP id V8s4tbrPXzJCKhlg (version=TLSv1 cipher=AES256-SHA bits=256 verify=NO) for ; Tue, 14 Oct 2014 04:38:08 -0700 (PDT) X-Barracuda-Envelope-From: bfoster@redhat.com X-Barracuda-Apparent-Source-IP: 209.132.183.28 X-ASG-Whitelist: Client Received: from int-mx14.intmail.prod.int.phx2.redhat.com (int-mx14.intmail.prod.int.phx2.redhat.com [10.5.11.27]) by mx1.redhat.com (8.14.4/8.14.4) with ESMTP id s9EBc0Ts007157 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-GCM-SHA384 bits=256 verify=FAIL); Tue, 14 Oct 2014 07:38:00 -0400 Received: from bfoster.bfoster ([10.18.41.237]) by int-mx14.intmail.prod.int.phx2.redhat.com (8.14.4/8.14.4) with ESMTP id s9EBbxTJ031730; Tue, 14 Oct 2014 07:37:59 -0400 Received: by bfoster.bfoster (Postfix, from userid 1000) id BF7B6120064; Tue, 14 Oct 2014 07:37:58 -0400 (EDT) Date: Tue, 14 Oct 2014 07:37:58 -0400 From: Brian Foster To: Dave Chinner Cc: xfs@oss.sgi.com Subject: Re: [PATCH v4] xfs: rework zero range to prevent invalid i_size updates Message-ID: <20141014113758.GA64776@bfoster.bfoster> X-ASG-Orig-Subj: Re: [PATCH v4] xfs: rework zero range to prevent invalid i_size updates References: <1413220285-24886-1-git-send-email-bfoster@redhat.com> <20141014001806.GG5267@dastard> <20141014005058.GH5267@dastard> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20141014005058.GH5267@dastard> User-Agent: Mutt/1.5.23 (2014-03-12) X-Scanned-By: MIMEDefang 2.68 on 10.5.11.27 X-Barracuda-Connect: mx1.redhat.com[209.132.183.28] X-Barracuda-Start-Time: 1413286688 X-Barracuda-Encrypted: AES256-SHA X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 On Tue, Oct 14, 2014 at 11:50:58AM +1100, Dave Chinner wrote: > On Tue, Oct 14, 2014 at 11:18:06AM +1100, Dave Chinner wrote: > > I'm running 3.17 + for-next + a handful of local patches, but this > > is the only patch that modifies anything in this area.

I do reproduce with v4 and v3. Note that this is the assert for having at least 1 indirect block reservation, so it's a separate problem (not a stale delalloc problem): http://oss.sgi.com/archives/xfs/2014-09/msg00337.html What looks like is going on here is this patch regresses current for-next due to our previous zero range workaround to flush on zero range. This was originally reproducible on tot, the zero range flush quiets it down by forcing delalloc conversion, and this patch reintroduces it simply by eliminating the flush. I've just recently got back to fixing that problem. I have a couple patches that need more testing, but I'll try to get them posted for review today.

There was some discussion of this in the v2 posting of this rfc. http://marc.info/?l=linux-xfs&m=141176024430150&w=2 Olaf's "readme" example at the above link is a pretty good example of what we're facing.

If you definately want to keep this code around I'll look into this, but right now I don't have plans to extend the patchset to support mixed case insensitivity in a single filesystem. -Ben From bpm@sgi.com Tue Oct 14 10:34:47 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=RP_MATCHES_RCVD autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id 3144F7F3F for ; Tue, 14 Oct 2014 10:34:47 -0500 (CDT) Received: from whiskey.americas.sgi.com (whiskey.americas.sgi.com [128.162.233.19]) by relay2.corp.sgi.com (Postfix) with ESMTP id E95B0304059; Tue, 14 Oct 2014 08:34:46 -0700 (PDT) Received: by whiskey.americas.sgi.com (Postfix, from userid 4600) id 671744266DC; Tue, 14 Oct 2014 10:34:46 -0500 (CDT) Date: Tue, 14 Oct 2014 10:34:46 -0500 From: Ben Myers To: Dave Chinner Cc: linux-fsdevel@vger.kernel.org, olaf@sgi.com, xfs@oss.sgi.com Subject: Re: [PATCH 08/16] xfs: change interface of xfs_nameops.hashname Message-ID: <20141014153446.GB2199@sgi.com> References: <20141003214758.GY1865@sgi.com> <20141003215844.GG1865@sgi.com> <20141006221708.GI2301@dastard> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20141006221708.GI2301@dastard> User-Agent: Mutt/1.5.20 (2009-06-14) On Tue, Oct 07, 2014 at 09:17:08AM +1100, Dave Chinner wrote: > On Fri, Oct 03, 2014 at 04:58:44PM -0500, Ben Myers wrote: > > From: Olaf Weber > > > > With the introduction of the xfs_nameops.normhash callout, all uses of the > > hashname callout now occur in places where an xfs_name structure must be > > explicitly created just to match the parameter passing convention of this > > callout.

The function has problems dividing up the indirect reserved blocks for scenarios where a single delalloc extent is split in two. Particularly, there aren't always enough blocks reserved for multiple extents in a single extent reservation. The solution to this problem is to allow the extent removal code to steal from the deleted extent to meet indirect reservation requirements. Move the block of code in xfs_bmapi() that updates the icsb fdblocks counter to after the call to xfs_bmap_del_extent() to allow the codepath to update the extent record before the free blocks are accounted. Also, reshuffle the code slightly so the delalloc accounting occurs near the xfs_bmap_del_extent() call to provide context for the comments.

When removing a delalloc range, it updates the indirect block reservation appropriately based on the removal. It currently enforces that the new indirect block reservation is less than or equal to the original. This is normally the case in all situations except for in certain cases when the removed range creates a hole in a single delalloc extent, thus splitting a single delalloc extent in two. It is possible with small enough extents to split an indlen==1 extent into two such slightly smaller extents. This leaves one extent with 0 indirect blocks and leads to assert failures in other areas (e.g., xfs_bunmapi() if the extent happens to be removed). Refactor the indirect reservation code into a new helper function invoked by xfs_bunmapi(). Allow the helper to steal blocks from the deleted extent if necessary to satisfy the worst case indirect reservation of the new extents. This is safe now that the caller does not update icsb counters until the extent is removed (such stolen blocks simply remain accounted as allocated). Fall back to the original reservation using the existing algorithm and warn if we end up with extents without any reservation at all to detect this more easily in the future. This allows generic/033 to run on XFS without assert failures.

For this to be achieved, XFS need to export a rename2() method, which I included in the first patch. The second patch is the real implementation of the RENAME_EXCHANGE flags, which most of the work I based on xfs_rename(). I'd like some suggestions about the way I handled journaling, probably XFS_TRANS_RENAME is not the best way to log the changes during the RENAME_EXCHANGE, and we might need a new journal type for this specific reason. BTW, this patchset passed the xfstests 23, 24 and 25 (specifically for RENAME_EXCHANGE), and I also tested the projectID inheritance problem, where both paths must be under the same projectID to be able to change (I'm going to implement this test into the xfstests too).

>=C2=A0 =C2=A0 It just create=C2=A0 a small dump file, and if I run the = same xfsdump again (or umount the filesystem), it will hang, like:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/= commit/fs/xfs?id=3Da8b1ee8bafc765ebf029d03c5479a69aebff9693

addresses the small backup file, and

[PATCH] xfs: bulkstat doesn't release AGI buffer on error

(on the list) most likely addresses the hang, I think.

WARN_ON(!mutex_is_locked(&inode->i_mutex)); because XFS doesn't use i_mutex but its private rwlock. I forgot to check dmesg after running xfstests for XFS and didn't notice this. Anyway, the solution is to just remove the assertion since it doesn't hold for all filesystems. Patch for that is attached. Thanks Fengguang for catching this.

If xfs_trans_commit() fails, we fall through to the error block and call xfs_trans_cancel(). This is incorrect on commit failure. If xfs_trans_reserve() fails, we jump to the error block, cancel the tp and restore the superblock qflags to oldsbqflag. However, oldsbqflag has been initialized to zero and not yet updated from the original flags so we set the flags to zero. Fix up the error handling in xfs_qm_log_quotaoff() to not restore flags if they haven't been modified and not cancel the tp on commit failure.

XFS_RENAME_SPACE_RES() covers directory removal and insertion. Here we are doing neither, which makes me wonder whether we need a block reservation at all. It does appear that we have a sf dir case where the inode number could cause a format conversion. Perhaps we need something that calculates the blocks required for the insertion of the max of both names (it seems like the conversion would only happen once, but we don't know which way)? I haven't spent a ton of time in directory code, so I could easily be missing something. The tr_rename log reservation considers four inodes, two directory modifications, a target inode unlink (the overwrite case), and alloc btree mods for directory blocks being freed. IIUC, the exchange case should only ever log four inodes and the possible dir format conversion (e.g., no unlink, no dir block frees). We could define a new tr_rename_xchg reservation that encodes that and documents it appropriately in the comment. It might be worth getting a second opinion from Dave or somebody before going too far ahead on the logging work... > + if (error == -ENOSPC) { > + spaceres = 0; > + error = xfs_trans_reserve(tp, &M_RES(mp)->tr_rename, 0, 0); > + } > + if (error) { > + xfs_trans_cancel(tp, 0); > + goto std_return; > + } > + > + /* > + * Attach the dquots to the inodes > + */ > + error = xfs_qm_vop_rename_dqattach(inodes); > + if (error) { > + xfs_trans_cancel(tp, cancel_flags); > + goto std_return; > + } > + > + /* > + * Lock all participating inodes.

That said, I wonder if we're splitting things at the right level because it looks like xfs_rename() could handle everything we have in xfs_cross_rename() up to about this point. I definitely don't think we should go too far and try to handle all of this in one function, even if there is some duplication in the directory name replacement and inode link management.

Could we do something like pass the flags (or some new parameter) to xfs_rename() and convert the meat of the directory update calls into a couple internal helpers? For example: xfs_rename(...) { /* setup tp, lock inodes, etc. */ if (rename_exchange) error = xfs_rename_exchange_int(...); else error = xfs_rename(...); if (error) ... /* tp completion handling */ return xfs_trans_commit(...); abort_return: ... return error; } ... and that could be done with another refactoring patch to prepare xfs_rename().

As below, the new dentry always gets the old mode. I suspect we don't care about the mode of the original dentry in traditional rename since that entry goes away. It looks like it would be set to 0 here in the exchange case, however, rather than ndentry->d_inode->i_mode (which we can't assume exists for the non-exchange case).

That smells like a splice architecture bug. splice write puts the pipe lock outside the inode locks, but splice read puts the pipes locks *inside* the inode locks. The recent commit 8d02076 "(->splice_write() via ->write_iter()") which went into 3.16 will be what is causing this. It replaced a long standing splice lock inversion problem (XFS iolock vs i_mutex http://oss.sgi.com/archives/xfs/2011-08/msg00122.html) by moving to a ->write_iter call under the pipe_lock. Only XFS reports this issue because XFS is the only filesystem that serialises splice reads against truncate, concurrent writes into the same region, extent manipulation functions via fallocate() (e.g. hole punch), etc. and it does so via the inode iolock that it takes in shared (read) mode during xfs_file_splice_read(). > josh > > [1] https://bugzilla.redhat.com/show_bug.cgi?id=1152813 > > [14689.265161] ====================================================== > [14689.265175] [ INFO: possible circular locking dependency detected ] > [14689.265186] 3.18.0-0.rc0.git2.1.fc22.x86_64 #1 Not tainted > [14689.265190] ------------------------------------------------------- > [14689.265199] atomic/1144 is trying to acquire lock: > [14689.265203] (&sb->s_type->i_mutex_key#13){+.+.+.}, at: > [] xfs_file_buffered_aio_write.isra.10+0x7a/0x310 > [xfs] > [14689.265245] > but task is already holding lock: > [14689.265249] (&pipe->mutex/1){+.+.+.}, at: [] > pipe_lock+0x1e/0x20 > [14689.265262] > which lock already depends on the new lock. > > [14689.265268] > the existing dependency chain (in reverse order) is: > [14689.265287] > -> #2 (&pipe->mutex/1){+.+.+.}: > [14689.265296] [] lock_acquire+0xa4/0x1d0 > [14689.265303] [] mutex_lock_nested+0x85/0x440 > [14689.265310] [] pipe_lock+0x1e/0x20 > [14689.265315] [] splice_to_pipe+0x2a/0x260 > [14689.265321] [] > __generic_file_splice_read+0x57f/0x620 > [14689.265328] [] generic_file_splice_read+0x3b/0x90 > [14689.265334] [] xfs_file_splice_read+0xb0/0x1e0 [xfs] > [14689.265350] [] do_splice_to+0x6c/0x90 > [14689.265356] [] SyS_splice+0x6dd/0x800 > [14689.265362] [] system_call_fastpath+0x16/0x1b splice read -> iolock(shared) -> pipe lock. > [14689.265368] > -> #1 (&(&ip->i_iolock)->mr_lock){++++++}: > [14689.265424] [] lock_acquire+0xa4/0x1d0 > [14689.265494] [] down_write_nested+0x5e/0xc0 > [14689.265553] [] xfs_ilock+0xb9/0x1c0 [xfs] > [14689.265629] [] > xfs_file_buffered_aio_write.isra.10+0x87/0x310 [xfs] > [14689.265693] [] xfs_file_write_iter+0x8a/0x130 [xfs] > [14689.265749] [] new_sync_write+0x8e/0xd0 > [14689.265811] [] vfs_write+0xba/0x200 > [14689.265862] [] SyS_write+0x5c/0xd0 > [14689.265912] [] system_call_fastpath+0x16/0x1b write(2) -> i_mutex -> iolock(exclusive) > [14689.265963] > -> #0 (&sb->s_type->i_mutex_key#13){+.+.+.}: > [14689.266024] [] __lock_acquire+0x1b0e/0x1c10 > [14689.266024] [] lock_acquire+0xa4/0x1d0 > [14689.266024] [] mutex_lock_nested+0x85/0x440 > [14689.266024] [] > xfs_file_buffered_aio_write.isra.10+0x7a/0x310 [xfs] > [14689.266024] [] xfs_file_write_iter+0x8a/0x130 [xfs] > [14689.266024] [] iter_file_splice_write+0x2ec/0x4b0 > [14689.266024] [] SyS_splice+0x381/0x800 > [14689.266024] [] system_call_fastpath+0x16/0x1b splice write -> pipe lock -> i_mutex [ -> iolock(exclusive) ] This reminds me of the mmap_sem and all the problems we have because we can't serialise page faults against IO path and data manipulation functions (e.g. hole punch).

Additionally the I don't see the 4-bytes per inode saving, what am I missing? Frankly, I don't see a difference in readability but since you and Al agree on that I concede to your taste :) > indirection could easily be optimized away by directly passing the > dquot array in various functions, but for now I'd like to keep it > simple. So after I wrote a patch to avoid the indirection in most places (we cannot avoid it during quotaon and quotaoff but those are corner cases) I also think it's better to leave it for a separate patch series. It's mostly trivial but there's lot of churn when functions prototypes change, names need to change, etc. and with that I'd probably do other cleanups of the quota API towards filesystems (to somewhat reduce number of functions). So I'll just change the patches to use the function call instead of indirection table as you suggest.

I'm basically seeing a writepage attempted for a page over a delalloc extent (imap in writepage reflects this), but at some point before we get into the allocation (I suspect between where we release and reacquire ilock in xfs_map_blocks() to iomap_write_allocate()) the delalloc blocks that relate this particular page to the extent disappear. An in-core extent dump after doing the allocation but before inserting into the extent tree shows the range to be allocated as a hole. Indeed, the allocator saw a hole (wasdel == 0) and ended up doing the full allocation while the transaction had a reservation for a delalloc conversion, which we end up overrunning. It's not quite clear to me how this is happening. I would expect truncate_pagecache_range() to serialize against writeback via page lock. Regardless, the scenario of writing back pages into unallocated space that writeback thinks is covered by delayed allocation suggests something racing with delalloc punching. The problem seems to disappear if I comment it out from zero range, so we might want to kill the above hunk entirely for the time being. Brian > > + /* > + * Punch a hole and prealloc the range.

All buffers are now 768K multiples--6144, 768, 768, and I'm told the app should be writing out full buffers. However I'm not seeing the throughput increase I should given the amount that the RMWs should have decreased, which, if my math is correct, should be about half (80) the raw actuator seek rate of these drives (7.2k SAS). Something isn't right. I'm guessing it's the controller firmware, maybe the test app, or both. The test app backs off then ramps up when response times at the controller go up and back down. And it's not super accurate or timely about it. The lowest interval setting possible is 10 seconds. Which is way too high when a controller goes into congestion. Does XFS give alignment hints with O_DIRECT writes into preallocated files? The filesystems were aligned at make time w/768K stripe width, so each prealloc file should be aligned on a stripe boundary. I've played with the various queue settings, even tried deadline instead of noop hoping more LBAs could be sorted before hitting the controller. Can't seem to get a repeatable increase. I've nr_requests at 524288, rq_affinity 2, read_ahead_kb 0 since reads are <20% of the IO, add_random 0, etc. Nothing seems to help really.

However I'm not seeing the throughput increase I should given the amount that the RMWs should have decreased, which, if my math is correct, should be about half (80) the raw actuator seek rate of these drives (7.2k SAS). Something isn't right. I'm guessing it's the controller firmware, maybe the test app, or both. The test app backs off then ramps up when response times at the controller go up and back down. And it's not super accurate or timely about it. The lowest interval setting possible is 10 seconds. Which is way too high when a controller goes into congestion. > > Does XFS give alignment hints with O_DIRECT writes into preallocated files? The filesystems were aligned at make time w/768K stripe width, so each prealloc file should be aligned on a stripe boundary. I've played with the various queue settings, even tried deadline instead of noop hoping more LBAs could be sorted before hitting the controller. Can't seem to get a repeatable increase. I've nr_requests at 524288, rq_affinity 2, read_ahead_kb 0 since reads are <20% of the IO, add_random 0, etc. Nothing seems to help really. Some additional background: Num. Streams = 350 WRITING: Num. Write Threads = 100 Avg. Write Rate = 72 KiB/s Avg. Write Intvl = 10666.666 ms Num. Write Buffers = 426 Write Buffer Size = 768 KiB Write Buffer Mem. = 327168 KiB Group Write Rate = 25200 KiB/s Avg. Buffer Rate = 32.812 bufs/s Avg. Buffer Intvl. = 30.476 ms Avg. Thread Intvl. = 3047.600 ms The 350 streams are written to 350 preallocated files in parallel. Yes, a seek monster. Writing without AIO currently. I'm bumping the rate to 2x during the run but that isn't reflected above. The above is the default setup. The app can't dump the running setup.

Those are usually important details, but in this case the information that matters is already present. There is a ratio of 31 (thirty one) between 'swidth' and 'sunit' and assuming that this reflects the geometry of the RAID5 set and given commonly available disk sizes it can be guessed that with amazing "bravery" someone has configured a RAID5 out of 32 (thirty two) high capacity/low IOPS 3TB drives, or something similar. It is even "braver" than that: if the device name "/data/fhgfs/fhgfs_storage" is dedscriptive, this "brave" RAID5 set is supposed to hold the object storage layer of a BeeFS highly parallel filesystem, and therefore will likely have mostly-random accesses. This issue should be moved to the 'linux-raid' mailing list as from the reported information it has nothing to do with XFS. BTW the 100MB/s aggregate over 31 drives means around 3MB/s per drive, which seems pretty good for a RW workload with mostly-random accesses with high RMW correlation. It is notable but not surprising that XFS works well even with such a "brave" choice of block storage layer, untainted by any "cowardly" consideration of the effects of RMW and using drives designed for capacity rather than IOPS.

You apparently have 31 effective SATA 7.2k RPM spindles with 256 KiB chunk, 7.75 MiB stripe width, in RAID5. That should yield 3-4.6 GiB/s of streaming throughput assuming no cable, expander, nor HBA limitations. You're achieving only 1/3rd to 1/2 of this. Which hardware RAID controller is this? What are the specs? Cache RAM, host and back end cable count and type? When you say read or write is fast individually, but read+write is slow, what types of files are you reading and writing, and how many in parallel? This combined pattern is likely the cause of the slowdown due to excessive seeking in the drives. As others mentioned this isn't an XFS problem. The problem is that your RAID geometry doesn't match your workload. Your very wide parity stripe is apparently causing excessive seeking with your read+write workload due to read-modify-write operations. To mitigate this, and to increase resiliency, you should switch to RAID6 with a smaller chunk. If you need maximum capacity make a single RAID6 array with 16 KiB chunk size. This will yield a 496 KiB stripe width, increasing the odds that all writes are a full stripe, and hopefully eliminating much of the RMW problem. A better option might be making three 10 drive RAID6 arrays (two spares) with 32 KiB chunk, 256 KiB stripe width, and concatenating the 3 arrays with mdadm --linear. You'd have 24 spindles of capacity and throughput instead of 31, but no more RMW operations, or at least very few. You'd format the linear md device with # mkfs.xfs -d su=32k,sw=8 /dev/mdX As long as your file accesses are spread fairly evenly across at least 3 directories you should achieve excellent parallel throughput, though single file streaming throughput will peak at 800-1200 MiB/s, that of 8 drives. With a little understanding of how this setup works, you can write two streaming files and read a third without any of the 3 competing with one another for disk seeks/bandwidth--which is your current problem. Or you could do one read and one write to each of 3 directories, and no pair of two would interfere with the other pairs. Scale up from here. Basically what we're doing is isolating each RAID LUN into a set of directories. When you write to one of those directories the file goes into only one of the 3 RAID arrays. Doing this isolates RMWs for a given write to only a subset of your disks, and minimizes the amount of seeks generated by parallel accesses.

Not all drives seek at the same rate. Typically for a RAID 6 array, every disk you add to the width of the lun slows the seek rate for full stripe writes by 2-3%. So a 12+2 lun is going to have an average seek rate of 25-30% lower than a 2+1 lun on full stripe writes.... > > Something isn't right.

The controller should not have any problems with this.

Why do you want to queue half a million IOs once the CTQ depth has overflowed? That's a major latency problem right there. You've got latency problems, so your should be removing any source of potential or variable latency in the IO stack. e.g. turning off all IO scheduler queuing, reducing CTQ depth and using write through caching so you can observe the behaviour of the raw luns. Strip it right back, then observe... > Some additional background: > > Num. Streams = 350 > WRITING: > Num. Write Threads = 100 > Avg. Write Rate = 72 KiB/s > Avg. Write Intvl = 10666.666 ms > Num.

If you don't know the physical layout of the files and what disks in the storage array they map to, then you can't determine what the seek times should be. If you can't work out what the seek times should be, then you don't know what the stream capacity of the storage should be. Keep in mind that single extent files are optimised for read performance, not write performance. i.e. by default XFS trades off some write performance to improve file read performance. Optimising for highest write speeds means linearising all writes (i.e. reducing seeks), while XFS's default behaviour is to separate them into different regions of the disk (increasing seeks). IOWs, write rates are likely to go up if you allow files to be fragmented and interleaved to make writes more sequential. The down side is that reads will then seek, but if reads aren't the primary workload, nor a performance sensitive operation, then perhaps you're optimising for the wrong operation....

The rename log reservation is the worse case that a rename operation requires - it is not specific to a particular rename instance. This new reanme type fits within the existing definition, so we should just use it unchanged. What it comes down to is that there is no point in trying to define reservations for every single possible type of operation we can do - it's just too much maintenance overhead to verify that they are correct after some incidental change. If we define the worst case, then everything else is covered and we don't have to care about whether we have the reservation for a specific case right, or indeed whether we are using the correct reservation for a specific rename transaction.... > > + if (error == -ENOSPC) { > > + spaceres = 0; > > + error = xfs_trans_reserve(tp, &M_RES(mp)->tr_rename, 0, 0); > > + } > > + if (error) { > > + xfs_trans_cancel(tp, 0); > > + goto std_return; > > + } This is not necessary. The spaceres == 0 case in the rename is for adding new directory entries at ENOSPC and that is checked by xfs_dir_canenter(). We are not calling that function (because we aren't adding a name) and therefore we can't run without a full space reservation.

Indeed, is restoring them even the right thing to do? The commit *may* have made it to disk, but a subsequent error during completion handling resulted in the commit failing....

I would expect > truncate_pagecache_range() to serialize against writeback via page lock. It does. But the problem won't be truncate_pagecache_range(), it will be that punching delalloc blocks doesn't serialise against the page lock. i.e. we run truncate_pagecache_range/truncate_setsize without holding inode locks, and they serialise against writeback via page locks. However, we run xfs_bmap_punch_delalloc_range() holding inode locks, but no page locks. Hence both can serialise against writeback, but not against each other. therefore: writeback zero range page_lock page is delalloc XFS_ILOCK_SHARED XFS_ILOCK_EXCL map delalloc xfs_iunlock punch delalloc range xfs_iunlock XFS_ILOCK_EXCL pagecache_truncate_range allocate HOLE!!!! page_lock xfs_iunlock starts page writeback unlocks page waits on writeback removes page from cache Basically, we back to the fundamental problem that we can't manipulate extent state directly if there are *unlocked* pages in the page cache over that range because we hold meaningful writeback state on the page. > Regardless, the scenario of writing back pages into unallocated space > that writeback thinks is covered by delayed allocation suggests > something racing with delalloc punching. The problem seems to disappear > if I comment it out from zero range, so we might want to kill the above > hunk entirely for the time being. Yes, but I think I see the way forward now. xfs_vm_writepage() needs to unconditionally map the page it is being passed rather than relying on the state of bufferheads attached to the buffer. We can't serialise the page cache state against direct extent manipulations, therefore we have to make all decisions based on one set of state we can serialise access to sanely. The issue is that we can't currently serialise extent manipulations against writeback easily, but I think I see a neat and easy way to do this, and it mirrors a technique we already use(*): add a cursor to track the active map we are operating on so that we know if we are about to modify and extent we are currently writing to. Actually, a cursor solves a couple of other problems in this mapping code - see the big comment in xfs_iomap_write_allocate() about using a single map to avoid lookup/unlock/lock/allocate race conditions with truncate/hole-punch. So I think I have a solution that moves us towards the goal of "die, bufferheads, die" and solves these writeback vs page cache vs extent manipulation issues - let me do a bit more thinking about it and I'll write something up. Cheers, Dave. (*) we use a cursor for a similar purpose during AIL traversal: to detect item deletion while the AIL lock was dropped that would cause us to follow an invalid list pointer. -- Dave Chinner david@fromorbit.com From david@fromorbit.com Sun Oct 19 20:48:28 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id 1B0F87F4E for ; Sun, 19 Oct 2014 20:48:28 -0500 (CDT) Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by relay1.corp.sgi.com (Postfix) with ESMTP id 0717D8F8039 for ; Sun, 19 Oct 2014 18:48:27 -0700 (PDT) X-ASG-Debug-ID: 1413769704-04cb6c2ef9a8ad0001-NocioJ Received: from ipmail06.adl2.internode.on.net (ipmail06.adl2.internode.on.net [150.101.137.129]) by cuda.sgi.com with ESMTP id WMaFy3mIp6obbpUq for ; Sun, 19 Oct 2014 18:48:24 -0700 (PDT) X-Barracuda-Envelope-From: david@fromorbit.com X-Barracuda-Apparent-Source-IP: 150.101.137.129 X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: AhIlAF9pRFR5LODnZGdsb2JhbABbgw5TWLkPBpMCgV2FawQCAoENFwEEeYQDAQEEOhwVDhAIAxgJJQ8FJQMhE4g+DsAGAQEBBwIBHxiGC4gXghcHhEsFlkaHEoFtmEEpL4JLAQEB Received: from ppp121-44-224-231.lns20.syd7.internode.on.net (HELO dastard) ([121.44.224.231]) by ipmail06.adl2.internode.on.net with ESMTP; 20 Oct 2014 12:17:51 +1030 Received: from dave by dastard with local (Exim 4.80) (envelope-from ) id 1Xg24c-0008Qg-Dv; Mon, 20 Oct 2014 12:47:50 +1100 Date: Mon, 20 Oct 2014 12:47:50 +1100 From: Dave Chinner To: "Kaul, Yaniv" Cc: "xfs@oss.sgi.com" , fstests@vger.kernel.org, esandeen@redhat.com Subject: Re: Can't build RPM of xfstests Message-ID: <20141020014750.GL7169@dastard> X-ASG-Orig-Subj: Re: Can't build RPM of xfstests References: <648473255763364B961A02AC3BE1060D03C7940C13@MX19A.corp.emc.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <648473255763364B961A02AC3BE1060D03C7940C13@MX19A.corp.emc.com> User-Agent: Mutt/1.5.21 (2010-09-15) X-Barracuda-Connect: ipmail06.adl2.internode.on.net[150.101.137.129] X-Barracuda-Start-Time: 1413769704 X-Barracuda-URL: http://192.48.176.15:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests=BSF_SC0_MISMATCH_TO X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.10750 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.00 BSF_SC0_MISMATCH_TO Envelope rcpt doesn't match header [ cc fstests@vger.kernel.org ] On Sun, Oct 12, 2014 at 02:58:50AM -0400, Kaul, Yaniv wrote: > I'm getting the sources from https://kernel.googlesource.com/pub/scm/fs/xfs/xfstests-dev (as I can't use git directly, only over HTTP(s) due to company policy) > I'm trying to compile the RPM on either CentOS 6.5 or 7, both fail identically.

I run it just fine out of a checked-out git repo, and it doesn't require installation; on the other hand, making it palatable for a proper FHS-compliant distro package would require a fair bit of restructuring beyond just the packaging scripts. And... I honestly have no idea how the Makepkgs stuff is supposed to work. I've never been a fan of upstream containing packaging bits anyway; different distros have different requirements, and the Makepkgs script has always seemed weird. RPM/specfiles are supposed to drive the build - the build isn't supposed to drive rpm. I think it'd be best to make a distro-specific specfile which knows how to handle an xfstests tarball. Trying to reverse engineer Makepkgs doesn't sound fun to me; rpmbuild knows how to do this stuff. Dropping a generic RPM specfile into the top level dir would probably be enough to get it off the ground even if it doesn't conform to any particular distro's packaging rules. I think it's up to those who want rpms to dig into this, for now. Dumping all files into /opt/xfstests is probably simplest, since FHS-compliance is probably a long ways off. -Eric From bernd.schubert@fastmail.fm Mon Oct 20 03:00:45 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=FREEMAIL_FROM,T_DKIM_INVALID autolearn=ham version=3.3.1 X-Original-To: xfs@OSS.SGI.com Delivered-To: xfs@OSS.SGI.com Received: from relay.sgi.com (relay3.corp.sgi.com [198.149.34.15]) by oss.sgi.com (Postfix) with ESMTP id 19DC37F4E for ; Mon, 20 Oct 2014 03:00:45 -0500 (CDT) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay3.corp.sgi.com (Postfix) with ESMTP id A68C9AC001 for ; Mon, 20 Oct 2014 01:00:41 -0700 (PDT) X-ASG-Debug-ID: 1413792036-04bdf038d0bd2e0001-ps1ADW Received: from out3-smtp.messagingengine.com (out3-smtp.messagingengine.com [66.111.4.27]) by cuda.sgi.com with ESMTP id 9UR18FAmQuseAy6i (version=TLSv1 cipher=AES256-SHA bits=256 verify=NO) for ; Mon, 20 Oct 2014 01:00:36 -0700 (PDT) X-Barracuda-Envelope-From: bernd.schubert@fastmail.fm X-Barracuda-Apparent-Source-IP: 66.111.4.27 Received: from compute4.internal (compute4.nyi.internal [10.202.2.44]) by gateway2.nyi.internal (Postfix) with ESMTP id 220D1205D2 for ; Mon, 20 Oct 2014 04:00:36 -0400 (EDT) Received: from frontend1 ([10.202.2.160]) by compute4.internal (MEProxy); Mon, 20 Oct 2014 04:00:36 -0400 DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; d=fastmail.fm; h= x-sasl-enc:message-id:date:from:mime-version:to:subject :references:in-reply-to:content-type:content-transfer-encoding; s=mesmtp; bh=hWnU18p2mj91DHgJPkr4msMKRZU=; b=ZCOz0CQhl0n1wHUfvk hRU91Be3s9Z2cTc+TzAyHZmz1DOBC/2GLDONGOvDqOiqr1qOj/fmo2uLgERBHqX9 UYrUGezDm9USRjjVWngMdN8o1/Kk0dWmJFaOtIiHrDC8wQ2z7UeJQqMMx4M913OK KSgDEJM+enu4jvUgOldhQMyK0= DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; d= messagingengine.com; h=x-sasl-enc:message-id:date:from :mime-version:to:subject:references:in-reply-to:content-type :content-transfer-encoding; s=smtpout; bh=hWnU18p2mj91DHgJPkr4ms MKRZU=; b=hp21pldvjjR0N1wYwncu6ALSbOpP6Iv00lgJUPHmbWvUL2YRAPe0D2 7W8w36fOZ1mhIuqYCkB+P5w+X1BVkrPa1MXkt9s0xCbW6r/f1PuZhNaefKAzq5Gl MkQ0ovzL6EoZuIXxuJZHCjmOOfJofXhNyJr6980GDmjx0HTDVGR1k= X-Sasl-enc: CmSlk1JZxt8XvOLZHi3VE6oORY1dR5uYS1iEhv8Rt2X9 1413792035 Received: from [192.168.1.22] (unknown [86.195.66.223]) by mail.messagingengine.com (Postfix) with ESMTPA id 8C035C00013; Mon, 20 Oct 2014 04:00:35 -0400 (EDT) Message-ID: <5444C122.4080104@fastmail.fm> Date: Mon, 20 Oct 2014 10:00:34 +0200 From: Bernd Schubert User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Thunderbird/31.1.2 MIME-Version: 1.0 Newsgroups: gmane.comp.file-systems.xfs.general To: Peter Grandi , Linux fs XFS Subject: Re: Problem about very high Average Read/Write Request Time References: <20141018143848.3baf3266@galadriel.home> <21571.36364.518119.806191@tree.ty.sabi.co.uk> X-ASG-Orig-Subj: Re: Problem about very high Average Read/Write Request Time In-Reply-To: <21571.36364.518119.806191@tree.ty.sabi.co.uk> Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: out3-smtp.messagingengine.com[66.111.4.27] X-Barracuda-Start-Time: 1413792036 X-Barracuda-Encrypted: AES256-SHA X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests=DKIM_SIGNED, DKIM_VERIFIED X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.10756 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- -0.00 DKIM_VERIFIED Domain Keys Identified Mail: signature passes verification 0.00 DKIM_SIGNED Domain Keys Identified Mail: message has a signature On 10/19/2014 12:10 PM, Peter Grandi wrote: >>> I am using xfs on a raid 5 (~100TB) and put log on external >>> ssd device, the mount information is: /dev/sdc on >>> /data/fhgfs/fhgfs_storage type xfs >>> (rw,relatime,attr2,delaylog,logdev=/dev/sdb1,sunit=512,swidth=15872,noquota). >>> when doing only reading / only writing , the speed is very >>> fast(~1.5G), but when do both the speed is very slow (100M), >>> and high r_await(160) and w_await(200000). > >> What are your kernel version, mount options and xfs_info output ?

I don't know if they are following FHS, but I doubt they use /opt.

What still isn't clear is how this gets past the pagecache truncate in such a state. The zero range path truncates pagecache before the delalloc punch, which does serialize on the page lock. If it gets the lock it completely tosses the page, which it looks like the mapping checks in writepage should handle. If it doesn't get the lock or the page is writeback, it looks like it waits on writeback. This is an fsx workload so it is single threaded I/O. I'm not quite seeing how we get through the writeback/pagecache truncate in a state with a delalloc page. > punch delalloc range > xfs_iunlock > XFS_ILOCK_EXCL pagecache_truncate_range > allocate HOLE!!!! page_lock > xfs_iunlock Ah, so this makes sense according to the code as it is today because we punch delalloc blocks and then truncate pagecache. Note that this zero range rework does the pagecache truncate first, then punches out the delalloc blocks. Hence my expectation of either seeing the page tossed or the extent converted before getting to the delalloc punch. > starts page writeback > unlocks page > waits on writeback > removes page from cache > > Basically, we back to the fundamental problem that we can't > manipulate extent state directly if there are *unlocked* pages in > the page cache over that range because we hold meaningful writeback > state on the page. > > > Regardless, the scenario of writing back pages into unallocated space > > that writeback thinks is covered by delayed allocation suggests > > something racing with delalloc punching.

I'm all for condensing our page state management towards killing buffer_head. Tracking down some of these issues has helped clarify the general problem for me and also shows that instances are quite difficult to root cause. This one in particular is a zero range operation that presumably works (no fsx failures), only to cause an implicit error in an asynchronous path (writeback) sometime later. That makes it difficult to detect and equally difficult to try and narrow down. > The issue is that we can't currently serialise extent manipulations > against writeback easily, but I think I see a neat and easy way to > do this, and it mirrors a technique we already use(*): add a cursor > to track the active map we are operating on so that we know if we > are about to modify and extent we are currently writing to. > Ok, so I take it this would allow us to mark an extent as "under modification" or "in-use" in the sense of its state is significant for a code sequence larger than an ilock critical section (i.e., an imap, extent-conversion, writeback sequence). Therefore, one side can invalidate another if a modification is made, or conversely the other side could simply block on the operation if that is more appropriate. I _think_ I get where you're going there, but I await more details. ;) I'll post a new version of this patch regardless because as mentioned previously, I'd like to get some kind of checkpoint into the tree that works correctly (no asserts), even if the implementation is not ideal. I've not been able to reproduce any asserts so far without the delalloc punch, but I'd also like to see if any of your subsequent testing uncovers anything else.

E.g., it attempts to allocate zeroed blocks over the range specified by the caller. The XFS implementation kills all delalloc blocks currently over the aligned range, converts the range to allocated zero blocks (unwritten extents) and handles the partial pages at the ends of the range by sending writes through the pagecache. The current implementation suffers from several problems associated with inode size. If the aligned range covers an extending I/O, said I/O is discarded and an inode size update from a previous write never makes it to disk. Further, if an unaligned zero range extends beyond eof, the page write induced for the partial end page can itself increase the inode size, even if the zero range request is not supposed to update i_size (via KEEP_SIZE, similar to an fallocate beyond EOF). The latter behavior not only incorrectly increases the inode size, but can lead to stray delalloc blocks on the inode. Typically, post-eof preallocation blocks are either truncated on release or inode eviction or explicitly written to by xfs_zero_eof() on natural file size extension. If the inode size increases due to zero range, however, associated blocks leak into the address space having never been converted or mapped to pagecache pages. A direct I/O to such an uncovered range cannot convert the extent via writeback and will BUG(). For example: $ xfs_io -fc "pwrite 0 128k" -c "fzero -k 1m 54321" ... $ xfs_io -d -c "pread 128k 128k" If the entire delalloc extent happens to not have page coverage whatsoever (e.g., delalloc conversion couldn't find a large enough free space extent), even a full file writeback won't convert what's left of the extent and we'll assert on inode eviction. Rework xfs_zero_file_space() to avoid buffered I/O for partial pages. Use the existing hole punch and prealloc mechanisms as primitives for zero range. This implementation is not efficient nor ideal as we writeback dirty data over the range and remove existing extents rather than convert to unwrittern. The former writeback, however, is currently the only mechanism available to ensure consistency between pagecache and extent state. Even a pagecache truncate/delalloc punch prior to hole punch has lead to inconsistencies due to racing with writeback. This provides a consistent, correct implementation of zero range that survives fsstress/fsx testing without assert failures. The implementation can be optimized from this point forward once the fundamental issue of pagecache and delalloc extent state consistency is addressed.

Those tags are basically meaningless from a release perspective, though. As it is, for the purpose of the discussion I'll argue that we don't need official release versions or tarballs and that anyone who needs packages for xfstests is Doing it Wrong(tm). Realistically, the current head commit ID works just fine as a release version and so I don't think we don't need tarballs or released versions of xfstests. xfstests is developer rather than end user focussed and so it is assumed that you understand git if you have a need for running xfstests... i.e. this works as a test machine deployment method and is easily scriptable and deployable on test machines: # # cd /opt # git clone # cd xfstests # make # # ./check -g auto And with that, there is no need for packaging.... That said, xfstests needs to be flexible so it can operate in all sorts of different environments, so how I do things really doesn't matter that much. If people really need xfstests to build RPMs so they can deploy RPMs, then like I said I'll take patches to make that work...

Yep, doesn't do much - s/LTINSTALL/INSTALL/ pretty much. Looks like a fine place to start. Rather than using Makepkgs, it may make more sense to just drop a sane generic .spec file into the top dir, then rpmbuild -ta would work. But then ... we don't distribute xfstests tarballs ... ;) -Eric > I don't maintain that so I don't know why the patch is needed. > > Greg > From greg.freemyer@gmail.com Mon Oct 20 18:32:32 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=FREEMAIL_FROM,T_DKIM_INVALID autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id AE2907F4E for ; Mon, 20 Oct 2014 18:32:32 -0500 (CDT) Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by relay2.corp.sgi.com (Postfix) with ESMTP id 9B36530404E for ; Mon, 20 Oct 2014 16:32:32 -0700 (PDT) X-ASG-Debug-ID: 1413847950-04cb6c2efbdd710001-NocioJ Received: from mail-wg0-f47.google.com (mail-wg0-f47.google.com [74.125.82.47]) by cuda.sgi.com with ESMTP id Sbqqqes3HSWsatWr (version=TLSv1 cipher=RC4-SHA bits=128 verify=NO) for ; Mon, 20 Oct 2014 16:32:31 -0700 (PDT) X-Barracuda-Envelope-From: greg.freemyer@gmail.com X-Barracuda-Apparent-Source-IP: 74.125.82.47 Received: by mail-wg0-f47.google.com with SMTP id x13so62852wgg.30 for ; Mon, 20 Oct 2014 16:32:30 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:in-reply-to:references:from:date:message-id:subject:to :cc:content-type; bh=7Bt6ZlOu0Gvsy9EfARh1RF4noGMEf6eBEXlSszkQ5Ko=; b=d5N67EYjh1b+A6PI+vDE1rbAvg5uFjVsURNaGXj+HBh2iQxToIWNQ1bbsf4+PEt5iy zC9Gvx9F0j86u6W9mePiDSbBr6mOnMxSkpJ+m2j7SbENUp+A9bPMFgL3T9FuAmuzcQWD oNnY89yT+uzYoRltskvArQCnCnjP08HoopzDJIPOqjFsGODJBMzjz9zHQR3ZNTL/Z4B2 NhoL8kEdjoXGu0etpjkA7i35pxEOK+ZKqhlFc+auxQDG+KuKSBQDhizkB7ql7p8apE0Y acBsgmZdEwgsoBjrd/oehQVYG2brWpySk8XpNFYuYWVId1WDk0ztDJ/iX6W/2iLArVfL SV9g== X-Received: by 10.194.57.210 with SMTP id k18mr8757578wjq.110.1413847950231; Mon, 20 Oct 2014 16:32:30 -0700 (PDT) MIME-Version: 1.0 Received: by 10.180.194.194 with HTTP; Mon, 20 Oct 2014 16:31:50 -0700 (PDT) In-Reply-To: <20141020230840.GP17506@dastard> References: <648473255763364B961A02AC3BE1060D03C7940C13@MX19A.corp.emc.com> <20141020014750.GL7169@dastard> <54448313.7040602@sandeen.net> <30CA1845-C213-49EA-8809-F1E7A98AE7F9@gmail.com> <54451427.9060306@sandeen.net> <20141020230840.GP17506@dastard> From: Greg Freemyer Date: Mon, 20 Oct 2014 19:31:50 -0400 Message-ID: Subject: Re: Can't build RPM of xfstests To: Dave Chinner X-ASG-Orig-Subj: Re: Can't build RPM of xfstests Cc: Eric Sandeen , "Kaul, Yaniv" , Eric Sandeen , fstests@vger.kernel.org, "xfs@oss.sgi.com" Content-Type: text/plain; charset=UTF-8 X-Barracuda-Connect: mail-wg0-f47.google.com[74.125.82.47] X-Barracuda-Start-Time: 1413847950 X-Barracuda-Encrypted: RC4-SHA X-Barracuda-URL: http://192.48.176.15:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests=DKIM_SIGNED, DKIM_VERIFIED X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.10781 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- -0.00 DKIM_VERIFIED Domain Keys Identified Mail: signature passes verification 0.00 DKIM_SIGNED Domain Keys Identified Mail: message has a signature -- Greg Freemyer On Mon, Oct 20, 2014 at 7:08 PM, Dave Chinner wrote: > On Mon, Oct 20, 2014 at 08:54:47AM -0500, Eric Sandeen wrote: >> On 10/20/14 6:55 AM, Greg Freemyer wrote: >> >> > Opensuse is building rpms of 1.1.1 so the build infrastructure isn't >> > too badly broken.

A potential use case with openSUSE and why I "think" they packaged it is to include a subset of xfstest in there automated testing. As of the last 9 months openSUSE's "factory" release has adopted a rolling release mechanism similar to rawhide, but possibly a little more reliable. Many submissions to factory (the rawhide equivalent) are pushed through a ring of automated QA tests. Separately on a daily basis the entire current factory release is pushed through a series of automated QA tests. If all QA tests pass, then a full factory snapshot is automatically released for end-user incorporation. My hope is that xfstests is packaged by openSUSE so it can easily be incorporated into that series of automated tests. If they are not yet doing that, then having xfstests packaged simplifies the future incorporation of xfstests into the auto-QA cycle. Overview: https://openqa.opensuse.org/tests/ Table of automated test results: https://openqa.opensuse.org/tests/ Notice for example that ext4 is a testsuite selection in the testsuite pull down. I assume that testsuite uses xfstests to exercise ext4 prior to an automated release of factory. The 2014-10-17 build of a couple days ago is an example of a build that failed the ext4 testsuite: https://openqa.opensuse.org/tests/27955 The 2014-10-18 build on the otherhand worked: https://openqa.opensuse.org/tests/28263 It is interesting to look through the various screen shots captured by the automated test system. I don't see automated tests for xfs or btrfs which is a surprise since both of them are default filesystem choices for factory. (btrfs is the default choice for / and xfs is the default for /home). Note: openSUSE still will do formal releases and the next one is openSUSE 13.2 due out next month. 13.2 should be getting lots of manual testing in addition to the automated QA testing.

Sure - i'm just pointing out that you don't need RPM to do that - git it just as good for deploying automated testing infrastructure ;) .... > Notice for example that ext4 is a testsuite selection in the testsuite > pull down.

It appears to be a "can we install opensuse" installer test that happens to be run on ext4. i.e. it's really product level testing (i.e. whether the opensuse build worked) not whether the filesystem works as it's supposed to. > I don't see automated tests for xfs or btrfs which is a surprise since > both of them are default filesystem choices for factory. (btrfs is > the default choice for / and xfs is the default for /home). Seeing as it's not actually doing filesystem level testing, it probably doesn't matter at all.

Not yet, as your report lacks any details necessary to even make a guess what the cause of your problem might be.

Sorry my delay to reply, I was in a software conference this week, and barely accessed my e-mails. I can certainly re-do this patch to avoid the name change. I used a new name to follow the VFS convention, although I also agree we 'should' get rig of several versions and keep just newer updates to the same syscalls. So, I'll re-do this patch and send a V2.

Thus filesystems which don't need it save 2 pointers in their inodes (would be 3 after we add project quota support into generic quota). The patch series also contains a change to quotactl so that each filesystem can set quota types it supports. This is in the end unrelated change (originally it was necessary for i_dquot moving but in the end I changed things so that it's not anymore). I can move that into a separate series but I was somewhat reluctant to do that since that would mean another 6 one-line patches to the same files we are changing here... If people like the patches, I will queue this series into my tree for the next merge window. For that I'd prefer to get acks from affected fs maintainers (the changes are pretty trivial and I don't feel it's a must but still I'd prefer fs maintainers to ack they are aware of the changes). Honza Changes since v1: * Inode field names are now named enum * Quota type masks now have names like QTYPE_MASK_{USR|GRP|PRJ} instead of opencoding shifts. Changes since v2: * Use ->get_dquots callback instead of inode fields framework * rebased on Linus' tree as of 3.18-rc1 + something.

In this specific case it is not an assumption, thanks to the prominent fact that the original poster was testing (locally I guess) and complaining about concurrent read/writes, which result in random like arm movement even if each of the read and write streams are entirely sequential. I even pointed this out, probably not explicitly enough: >> when doing only reading / only writing , the speed is very >> fast(~1.5G), but when do both the speed is very slow >> (100M), and high r_await(160) and w_await(200000). BTW the 100MB/s aggregate over 31 drives means around 3MB/s per drive, which seems pretty good for a RW workload with mostly-random accesses with high RMW correlation. Also if this testing was appropriate then it was because the intended workload was indeed concurrent reads and writes to the object store. It is not a mere assumption in the general case either; it is both commonly observed and a simple deduction, because of the nature of distributed filesystems and in particular parallel HPC ones like Lustre or BeeGFS, but also AFS and even NFS ones. * Clients have caches. Therefore most of the locality in the (read) access patterns will hopefully be filtered out by the client cache. This applies (ideally) to any distributed filesystem. * HPC/parallel servers tend to whave many clients (e.g. for an it could be 10,000 clients and 500 object storage servers) and hopefully each client works on a different subset of the data tree, and distribution of data objects onto servers hopefully random. Therefore it is likely that many clients will access with concurrent read and write many different files on the same server resulting in many random "hotspots" in each server's load. Note that each client could be doing entirely sequential IO to each file they access, but the concurrent accesses do possibly widely scattered files will turn that into random IO at the server level. Just about the only case where sequential client workloads don't become random workloads at the server is when the client workload is such that only one file is "hot" per server. There is an additional issue favouring random access patterns: * Typically large fileservers are setup with a lot of storage because of anticipated lifetime usage, so they start mostly empty. * Most filesystems then allocate new data in regular patterns, often starting from the beginning of available storage, in an attempt to minimize arm travel time usually (XFS uses various heuristics, which are somewhat different whether the option 'inode64' is specified or not). * Unfortunately as the filetree becomes larger new allocations have to be made farther away, resulting in longer travel times and more apparent randomness at the storage server level. * Eventually if the object server reaches a steady state where roughly as much data is deleted and created the free storage areas will become widely scattered, leading to essentially random allocation, the more random the more capacity used. Leaving a significant percentage of capacity free, like at least 10% and more like 20%, greatly increases the chance of finding free space near to put new data near to existing "related" data. This increases locality, but only at the single-stream level; therefore is usually does not help that much widely shared distributed servers; and in particular does not apply that much to object stores, because usually they obscure which data object is related to which data object. The above issues are pretty much "network and distributed filesystems for beginners" notes, but in significant part also apply to widely shared non network and non distributed servers on which XFS is often used, so they may be usefully mentioned in this list.

If what I'm told about the controller statistics screen is correct, RMWs, or "small destages", are far less than 0.5% of total destages. However that rate didn't change noticeably when I switched to stripe aligned buffer sizes of 768K vs 160K. Watching the stats in real time shows zero small destages for long periods of time, then a burst of them, then nothing again. I'm told the firmware ignores all low rate IOs so cache lines can be dedicated to the fast writers, and it only waits 3 seconds to assemble full stripes for writeback. So what I'm seeing maybe doesn't match what I'm being told. I've been given no docs for the controllers because they haven't apparently been written yet. I must trust what I'm told. Again, these controllers are in a beta stage of development. Hot LUNs isn't an issue as we have one filesystem per LUN, and one LUN per controller. At least in this test rig. >>> should be about half (80) the raw actuator seek rate of these >>> drives (7.2k SAS). > > Not all drives seek at the same rate.

And partial stripe writes will hit a subset of disks, thus the associated RMW read will cause extra seeks on one or more of these, and possibly two others to read parity (RAID6). The rig I'm testing at the moment has two 12+1 RAID5 arrays so, only one parity seek on RMW. >>> Something isn't right. I'm guessing it's >>> the controller firmware, maybe the test app, or both.

When a controller goes into congestion I see await and avgqu-sz in iostat jump from 15-50ms steady state up into the hundreds, then into the thousands of ms if we don't back down the IOs being submitted. This is with O_DIRECT, and with and without using AIO. Once we do back it down the controller eventually recovers after tens of seconds to a minute or so, and wait and queue size drop back down to 'normal'. Due to the number of streams write-through mode would simply make every IO an RMW and throughput would be abysmal. I've been testing a two LUN config with 402 streams per LUN, per XFS filesystem, but the design is up to 14 LUNs. So we're talking in excess of 5600 IO streams with the test harness, possible over 10k in customer hands, or 2600 to 5000 IO streams per controller. So writeback and sorting high rate sectors into stripes is mandatory. With the to LUN setup I'm working with I see the controllers go into congestion and iostats await jumps from 10-50ms steady state up into the hundreds and low thousands of ms. And avgqu-sz just soars. Whether this is due to poor writeback performance or seeking the drives to death remains to be seen. Could be a combination of both. >>> Does XFS give alignment hints with O_DIRECT writes into >>> preallocated files? > > What do you mean? if the file is preallocated and aligned, then > the IO alignment is wholly up to the application. i.e. if the > application is not doing aligned IO, then there's nothing the > filesystem can do to align it... I mean during writeout to the block layer. O_DIRECT writes from the app must be multiples of 4K. Does XFS do anything different on writeout if the app writes 160k vs 768k, when the FS was created with alignment, writing to files created with posix_fallocate()? Does XFS group them into clusters of 1536 sectors? Or does it just sling pages (8 sectors) to the block layer? Forgive my ignorance. Our mentoring sessions never got this deep into the stack. Though we did touch the surface on CDBs and DMA from memory to the HBA in one discussion. >>> The filesystems were aligned at make time >>> w/768K stripe width, so each prealloc file should be aligned on >>> a stripe boundary. > > "should be aligned"? You haven't verified they are aligned by using > with 'xfs_bmap -vp'? If I divide the start of the block range by 192 (768k/4k) those files checked so far return a fractional value. So I assume this means these files are not stripe aligned. What might cause that given I formatted with alignment? >>> I've played with the various queue settings, >>> even tried deadline instead of noop hoping more LBAs could be >>> sorted before hitting the controller.

Why do you want to queue half a million IOs > once the CTQ depth has overflowed? That's a major latency problem > right there. As I said I was hoping this would give the elevator a larger window in which to sort IOs into sequential writes. The documentation of nr_requests is pretty sparse. Says the kernel will use only as many as needed, IIRC. The default is 128 and I saw additional throughput with 8192. I bumped it up to 131072, then 524288 as a test. Neither of the last two seems to help or hurt, but 8192 helped, with noop. > You've got latency problems, so your should be removing any source Latency is only a problem once the controller becomes saturated and congested. This occurs somewhere between 250-400 MB/s, but is variable. It seems to depend on which sets of files are being written at a given moment. Due to the scattered file layout across all 44 AGs it seems logical to me that seeking up/down the platters is the primary problem. We're riting 403 files in parallel, albeit at different rates. If at one moment we're mostly hitting AGs 0-10 we're not seeking all that much. The next moment we may be writing two high rates files, one in AG0 and one in AG44, and 50 medium rate files in AGs 12-35. The application data rate hasn't changed, but our seek distance, pattern, and times, are dramatically increased. I've not yet performed a full file location analysis as we generate over 27k files, and I've not figured out a way to automate this. But I have already recommended we optimize the file layout, if possible, to avoid this situation, as I know we already have this seek latency problem to some degree. > of potential or variable latency in the IO stack. e.g. turning off > all IO scheduler queuing, reducing CTQ depth and using write through > caching so you can observe the behaviour of the raw luns. Strip it > right back, then observe... As I said we can't do write-through. And I'm pretty sure the latency is seek latency, not IO path latency. The disks are slow, 7.2k, in parity RAID, and we're writing 400 files concurrently--2 fast, 50 medium, and 350 slow, along with 20% random reads thrown in, so reading 80 files concurrently with the writes. All against 12 effective 7.2k spindles in RAID5, or RAID6. Common sense, or should I say experience, tells me the performance cliff is insufficient actuator bandwidth for the workload as we currently lay out the files across the AGs. So this is where I'm focusing my efforts at the moment. >> Some additional background: >> >> Num. Streams = 350 >> WRITING: >> Num. Write Threads = 100 >> Avg. Write Rate = 72 KiB/s >> Avg.

Interestingly, I tried to explain this on day one during my site visit, but nobody wanted to listen: "We don't have to worry about file layout with EXT4. We shouldn't have to with XFS. We should just be able to create our directories and files how we want on a single mount point. etc, etc". 6 weeks later, they're finally ready to listen, somewhat, after all other tweaking has led to very few gains. Nobody wants to rewrite their app, whether the test harness group, or the production app group, to get performance. This is their first time through this. AAIU, their previous product didn't use a filesystem, but wrote raw to the storage, similar to how some DB vendors used to do it. So simply getting them to listen to knew ways of doing things is difficult. I guess on the plus side they may keep extending my contract as they find more value in the advice and information I'm providing. Moving so slow and chewing through concrete walls is frustrating, however. > Keep in mind that single extent files are optimised for read > performance, not write performance. i.e. by default XFS trades off > some write performance to improve file read performance.

Ok, so their idea in using preallocated files was to guarantee space and prevent file and free space fragmentation. They loop through the files once they fill, overwriting them at some point for reuse, IIUC. The large stream files are 2.5-4.8 GB, and those are the largest, the mediums are 1.5-2.7 GB, the smalls are 197-314 MB. We should be able to split them up across the AGs in a manner in which the heads are sweeping only one or two adjacent AGs at a time for each 402 IOs, walking from the outer platter edge to inner as we progress through the files. I've checked a few of the large and they are two extents each, one very large one in AG13 and a very small one in AG15. This is a result of spillage when AG13 filled, I assume. A binary creates the directories and files and I've not seen the source yet. I'm guessing it's done in parallel instead of serially, so the directories are likely scattered across the AGs in a random order. Speaking of this, when I straighten this out, how does one create a large number of directories serially as to ensure placement on sequential AGs? Do waits need to be added between each mkdir, for example? > IOWs, write rates are likely to go up if you allow files to be > fragmented and interleaved to make writes more sequential. With this many write streams and slow disks I think the primary goal should be minimizing large distance seeks during writes (i.e. AG0 to AG43 and back, platter edge to platter edge). Proper file placement matching the application's write pattern should achieve this. Does it matter then if we use preallocated or allocated files? Sticking with prealloc files prevents fragmentation, and thus free space btree lookup slowdowns. Or am I missing you here? > The down side is that reads will then seek, but if reads aren't the > primary workload, nor a performance sensitive operation, then > perhaps you're optimising for the wrong operation.... Perhaps. I think it's more likely we just haven't been on exactly the same page, probably because I'd not explained things thoroughly enough to this point. My next test is to be 44 O_DIRECT write threads in parallel, writing one allocated file in each AG, then 22 files each in AG0 and AG1. This to demonstrate the throughput differences due to full stroke platter seeking vs localized short stroke seeking. Sure, I'll lose some allocation parallelism but it should still demonstrate the point. I need something to convince the guys that modifying their app has promise.

I'm still looking for that one good recipe to fix xfsdump in my i686 Pentium 4 dungeon here, currently using yesterday morning's git kernel + xfs-oss/for-next. The test dataset is a basic slackware-current setup, regular kernel source, -stable kernel source, on v5-superblock/finobt XFS (mkfs.xfs -m crc=1,finobt=1 ...). The dataset uses about 7 GB of disk space. This letter is half-baked thoughts, only here to express the idea "don't think you're out of the woods yet!" in some primitive manner. The first patch seems to get rid of the earliest xfsdump premature SUCCESS, the one where xfsdump ran for less than 10 seconds and left a dump file of less than 1 MB. BTW, in the commit message and to `git log xfs-oss/for-next`, the commit message for the patch starts "caused a regression in xfs_inumbers" but does not mention which commit caused the regression. With the second patch applied, the dump size increases to about 1 decimal GB before exiting, same size in three different runs. I think I tried the patch "xfs: Check error during inode btree iteration in xfs_bulkstat()"--no other similar patches in my mailing list patchset download-- and xfsdump dumped up to 1.2 decimal GB, same size in two different runs. These patches are being run through xfstests as I work, so there's nothing there to report yet. It was only this morning that I got tar to complete a system backup without asserting in some way (hangcheck timer expires, stack varies), and the last oops got into that uncomfortable xfs_dir3_leaf area. Should this happen again, I'll either post some traces or the output of `xfsdump -v 3 ...` I was rushed into work today and couldn't grab the logs. Should `xfsdump -v 3 ...` report SUCCESS for one code and an error for the second return code, that second code has been "unknown error." I've never run xfsdump at -v 3 before and don't know if that is normal. The rest is still being fleshed out. tar seems to be OK, so long as xfsdump has not been invoked beforehand. tar has not been run enough times to get a true 1:1 correlation on it, though. The current goal is to reconstruct the filesystem and see if all problems magically go away. So far, xfs_repair has reported no errors on this filesystem. Thanks!

Why don't you keep this bitmask in the dquot.c instead of pushing it to the caller? So far usage of s_dquot is mostly confined to dquot.c (with a few leaks to the filesystems using it), so keeping it that way seems like a good idea.

So there are two reasons: 1) Currently if you call quotactl() with invalid quota type you'll get EINVAL. To maintain this with addition of project quotas you need to check the types early before calling check_quotactl_permission() and other checks. 2) I didn't want filesystem quotactl callbacks to deal with quota types they don't support. Sure each fs could do a type check in the callback but this looked easier. Now I see your point about s_dquot and I can move allowed_types out of s_dquot if that makes you happier. But otherwise what I did still seems as the best solution to me.

It is lots of text and does not help the op at all. And the claim/speculation that the parallel file system would introduce random access is also wrong. Before anyone can even start to speculate, the op first needs to provide the exact IO pattern and information about /dev/sdc.

It is pleasing that you seem to know at least that by themselves =ABLow speed and high latencies=BB are indeed not sufficient. But in =ABthe specific case=BB what is sufficient to make a good guess is what I wrote, which you seem to have been unable to notice or understand. >> BTW the 100MB/s aggregate over 31 drives means around 3MB/s >> per drive, which seems pretty good for a RW workload with >> mostly-random accesses with high RMW correlation. > The op did not provide sufficient information about the IO > pattern to know if there is RMW or random access involved. The op of =ABthe specific case=BB reported that the XFS filesystem is configured for a 32-wide RAID5 set and that: > when doing only reading / only writing , the speed is very > fast(~1.5G), but when do both the speed is very slow and perhaps your did not notice that; or did not notice or understand that I wrote subsequently, as you seemed to be requesting a detailed explanation of my conclusion, that: >> [ ... ] concurrent read/writes, which result in random like >> arm movement even if each of the read and write streams are >> entirely sequential. [ ... ] Because then there are at least two hotspots, the read one and the write one, except in the very special case that an application is reading and writing the same block each time. Even worse, since in =ABthe specific case=BB we have an "imaginative" 32-wide RAID5 unless the writes are exactly aligned with the large stripes there is going to be a lot of RMW resulting in the arms going back and forth (and even if aligned many RAID implementation still end up doing a fair bit of RMW). Knowing that and that it is a 32-wide RAID5 and the disks are 3TB in size (low IOPS per GB) and that the result is poor for single threaded but reasonable for double threaded, and that XFS in general behaves pretty well should be sufficient to give a reasonable guess: >>>>> This issue should be moved to the 'linux-raid' mailing list >>>>> as from the reported information it has nothing to do with >>>>> XFS. But I am just repeating what you seem to have been unable to read or understand... PS: as to people following this discussions, there can be many reasons why that 31-wide RAID5, which is such a very "brave" setup, is behaving like that on randomish access patterns arising from concurrent read-write, such as initial sync still going on, not so good default settings or scheduling of so many hw (as suggested by the 'sdc' instead of 'md$N') RAID HAs, etc., and some of these interact with how XFS operates, but it is indeed a discussion for the Linux RAID list at least first.

Perhaps you have missed the explicit qualification =ABin the general case=BB of =ABdistributed filesystems and in particular parallel HPC ones=BB or perhaps you lack familiarity with =ABLustre or BeeGFS, but also AFS and even NFS ones=BB most of which have client caches and usually enabled, and that might justify your inability to consider =ABthe general case=BB. >> Therefore most of the locality in the (read) access patterns >> will hopefully be filtered out by the client cache.

It is good but somewhat pointless that you can understand the meaning of =ABmost of the locality in the (read) access patterns will hopefully be filtered out by the client cache=BB and agree with it, and supply an example, but unfortunately you seem to have the naive expectation that: >> Local or remote file system does not matter here. It can matter as: * In the local case there is a single cache for all concurrent applications, while in the distributed case there is hopefully a separate cache per node, which segments the references (as well as hopefully providing a lot more cache space). * In the purely local case there is usually just one level of caching, in the distribured case usually there are two levels, often resulting in rather different access patterns to the object stores in the server. So the degree of filtering can be and often is quite different; which is usually quite important because network transfers add a cost. As to these three comments I am perplexed: >> Therefore it is likely that many clients will access with >> concurrent read and write many different files on the same >> server resulting in many random "hotspots" in each server's >> load. > If that would be important here there would be no difference > between single write and parallel read/write.

Because you seem rather confusedm, as my explanation was the answer to this question you asked: >>> Where do you get the assumption from that FhGFS/BeeGFS is >>> going to do random reads/writes or the application of top >>> of it is going to do that? and in it you mention no special case like =AB1-thread write=BB, or =AB2-thread read/write=BB. Also such simple special cases don't happen much in =ABthe object storage layer=BB of any realistic =ABhighly parallel filesystem=BB, which are often large with vast and varied workloads, as I tried to remind you: >> HPC/parallel servers tend to whave many clients (e.g. for >> an it could be 10,000 clients and 500 object storage >> servers) and hopefully each client works on a different >> subset of the data tree, and distribution of data objects >> onto servers hopefully random. Therefore there are likely to be many dozens or even hundreds of threads accessing objects per object store, with every pattern of read and write and to rather unrelated objects, not just 1 or 2 threads and single write or read/write. That's one reason why XFS is so often used for those object stores: it is particularly well suited to highly multithreaded access patterns to many files, as the XFS has benefited from quite a bit of effort in finer grained locking, and XFS uses some mostly effective heuristics to distribute files across the storage it uses in hopefully "best" ways. >> The above issues are pretty much "network and distributed >> filesystems for beginners" notes, > It is lots of text In my original reply I was terse and did not explain every reason why =ABthe object storage layer of a BeeFS highly parallel filesystem=BB is =ABlikely have mostly-random accesses=BB because I assumed it is common knowledge among somewhat skilled readers; but to a point I am also patient with beginners, even those who seem to become confused about which question they themselves asked. Also I am trying to quote context because you seem confused as to what the content of even your questions is. > and does not help the op at all. That seems unfortunately right, as to me you still seem very confused as to the workloads likely experienced by object stores for highly parallel filesystems despite my efforts in trying to answer in detail the question you asked: >>> Where do you get the assumption from that FhGFS/BeeGFS is >>> going to do random reads/writes or the application of top >>> of it is going to do that? At least as I already pointed out my answer to your question is at least somewhat topical for the XFS list, for example by hinting about using less "brave" configurations than 32-disk RAID5 sets. > And the claim/speculation that the parallel file system would > introduce random access is also wrong. As far as I can see it was only who you mentioned that because I discussed just the consequences of the likely access patterns of =ABthe application of top of it=BB part of your question. It seemed strange to me that you would ask why =ABFhGFS/BeeGFS is going to do random reads/writes=BB because filesystems typically don't do =ABread/writes=BB except as a consequence of application requests, so I ignored that other part of your question.

I've some other issue here.
The xfsdump work, but xfsrestore can't restore the dump file cor= rectly.
Got a lot of message like:
/sbin/xfsrestore: NOTE: ino = 131 salvaging file, placing in orphanage/7772637.4193481073/resource98761.i= ni
and
/sbin/xfsrestore: NOTE: ino 50858443 gen 697595483 not = referenced: placing in orphanage

Compare the file, some files = are not restored.

the xfsdump will hang after this message:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/= commit/fs/xfs?id=3Da8b1ee8bafc765ebf029d03c5479a69aebff9693

addresses the small backup file, and

[PATCH] xfs: bulkstat doesn't release AGI buffer on error

(on the list) most likely addresses the hang, I think.

Peter, I really don't care if you are right or wrong, your response is entirely inappropriate for this forum. Wheaton's Law: "Don't Be a Dick." Bernd is entitled to point out how tenuous your thread of logic is - if he didn't I was going to say exactly the same thing - it is based entirely on a house of assumptions you haven't actually verified. An appropriate response would be to ask the OP to describe their workload and storage in more detail so you can verify which of your asumptions were correct and which weren't, and take the discussion =66rom there. But instead of taking the evidence-based verification path, you've resorted to personal attacks to defend your tenuous logic. That is out of line and not acceptible behaviour. Knowledge is not a cudgel to beat people down with. Nobody really cares how much you know, nor do they need you to try to prove you know more than they do. If you succeed in proving how much of an Expert(tm) you are, then the only thing that people will remember about you is "what a dick that guy is". Unfortunately, Peter, you've made a habit of this behaviour. Every discussion thread you enter ends up with you abusing someone because they dared to either question your assertions or didn't understand what you said precisely. Indeed, I've come to assosicate your name with such behaviour over the past couple of years, to the point where I see your name in a thread and I wonder what will trigger you to abuse someone before I've even read the email. With this email, you've finally reached my Intolerable Dickhead On The Internet Threshold. Given that this is on the XFS mailing list, and I'm the XFS Maintainer it falls to me to draw a line in the sand: such behaviour is not acceptible in this forum. In future, Peter, please do not post to the list if you can't be nice or stay on topic. We don't need you to "help" by abusing people; we get along and solve problems just fine without you. Hence if you can't play nicely with others then please go away and don't come back. -Dave. --=20 Dave Chinner david@fromorbit.com --tThc/1wpZn/ma/RB Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJUSsh0AAoJEK3oKUf0dfodJVIP/3AtghnSkekVnecW1ohKMQJb Ts/SrT1mv7FlrOdPMRctk88zgn8f47i+7b7nyjLXOZNJ/aQfT2V70OKB3C4o1p5q AdSDSBU4h1EY3E3QpL+Jy0Yal1whL5UucLkXsrnoFR490KtZZPpjfJ2qigKB7P7X tXKEo4GLvWbPzZcOngiO7X2T7dvSft/8p+2sdbNBPkgKSI8QxaZmNco0aRpRwPJ8 RbrKO3enlJ9lQK+V8MYgOvk+TWoW6w6xONEa9LSN15yYUID+GX4koo9HRoG3UiX1 yxNDfvUKBLKwGpnjHSI8h2+wjKZW4JZvEcn2rcbAevpS0d06ZYL+irZoSFqazs48 9OtmV0S1mknEyD1r+ga/NtxJZrsjajlvq4Rn1G4jblbMtmtV+oVlg4La4IDfKBIG rXTeYcehp1Pj2e8uj0VV+dgxwXCIwKeEeh8QZ36zb9BkWZZlJpc3TTP4/3iAVF1h hcn+k+FHnM5tawzU3LVxRmbKS+8oyB7F2S1X6wLYt1/1lb/t/MIt7SAAwuGRITlZ H0OM0+sTWzDFfPMwluoBSu6iiEJJae+12klfSfPgvMzamD4mvVvr/cWqHtOWlxT4 X2JsfoCNIklUCMHpd7lvyWpRTTj/ErjFNJH52Hxx7RTjRPTkKWa/8BGyACsBDwFK MAUdgT5xA1cOxh/zcgQs =a4+W -----END PGP SIGNATURE----- --tThc/1wpZn/ma/RB-- From stan@hardwarefreak.com Fri Oct 24 17:07:39 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id 495B97F37 for ; Fri, 24 Oct 2014 17:07:39 -0500 (CDT) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay1.corp.sgi.com (Postfix) with ESMTP id 0B47B8F8039 for ; Fri, 24 Oct 2014 15:07:35 -0700 (PDT) X-ASG-Debug-ID: 1414188454-04bdf038cf3c5140001-NocioJ Received: from greer.hardwarefreak.com (mo-65-41-216-221.sta.embarqhsd.net [65.41.216.221]) by cuda.sgi.com with ESMTP id T9AB0K5ADfIl4KUQ for ; Fri, 24 Oct 2014 15:07:34 -0700 (PDT) X-Barracuda-Envelope-From: stan@hardwarefreak.com X-Barracuda-Apparent-Source-IP: 65.41.216.221 X-Barracuda-User-Whitelist: xfs@oss.sgi.com Received: from [134.64.128.163] (unknown [192.65.45.20]) by greer.hardwarefreak.com (Postfix) with ESMTPA id EC0176C0FA; Fri, 24 Oct 2014 17:07:33 -0500 (CDT) Message-ID: <544ACDC4.1070501@hardwarefreak.com> Date: Fri, 24 Oct 2014 17:08:04 -0500 From: Stan Hoeppner User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Icedove/24.7.0 MIME-Version: 1.0 To: Eric Sandeen , xfs@oss.sgi.com Subject: Re: makefs alignment issue References: <544AB289.8010005@hardwarefreak.com> <544AB338.2050905@sandeen.net> X-ASG-Orig-Subj: Re: makefs alignment issue In-Reply-To: <544AB338.2050905@sandeen.net> Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: mo-65-41-216-221.sta.embarqhsd.net[65.41.216.221] X-Barracuda-Start-Time: 1414188454 X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 On 10/24/2014 03:14 PM, Eric Sandeen wrote: > On 10/24/14 3:11 PM, Stan Hoeppner wrote: >> Just remade a couple of filesystems and received an alignment msg I >> don't recall receiving previously: >> >> # mkfs.xfs -f -d su=64k,sw=12 /dev/s2d_a1l003 >> mkfs.xfs: Specified data stripe width 1536 is not the same as the volume >> stripe width 2048 > > so specified geometry that differs from the underlying device... > >> meta-data=/dev/s2d_a1l003 isize=256 agcount=44, >> agsize=268435440 blks >> = sectsz=512 attr=2, projid32bit=0 >> data = bsize=4096 blocks=11709285376, imaxpct=5 >> = sunit=16 swidth=192 blks >> naming =version 2 bsize=4096 ascii-ci=0 >> log =internal log bsize=4096 blocks=521728, version=2 >> = sectsz=512 sunit=16 blks, lazy-count=1 >> realtime =none extsz=4096 blocks=0, rtextents=0 >> >> >> /dev/s2d_a1l003 is an alias to dm-0 which is a dm-multipath device to a >> LUN on hardware RAID.

There are some heuristics in mkfs to ignore things that just obviously don't make sense. Perhaps we should ignore anything with a sector-sized "stripe unit". (I'll also ask the dm folks why they set it this way). Dave, any thoughts? > So it seems I can safely ignore this mkfs msg. Probably so, but it'd be nice to get rid of it if we could, either by ignoring sector-sized "stripe units" or changing what dm reports; not sure. -Eric > Thanks, > Stan > From sandeen@sandeen.net Fri Oct 24 17:27:05 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id CA8117F37 for ; Fri, 24 Oct 2014 17:27:05 -0500 (CDT) Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by relay2.corp.sgi.com (Postfix) with ESMTP id B8897304039 for ; Fri, 24 Oct 2014 15:27:02 -0700 (PDT) X-ASG-Debug-ID: 1414189621-04cbb070c82c44a0001-NocioJ Received: from sandeen.net (sandeen.net [63.231.237.45]) by cuda.sgi.com with ESMTP id Zsb1zvwVLFPUibNY for ; Fri, 24 Oct 2014 15:27:01 -0700 (PDT) X-Barracuda-Envelope-From: sandeen@sandeen.net X-Barracuda-Apparent-Source-IP: 63.231.237.45 Received: from liberator.sandeen.net (liberator.sandeen.net [10.0.0.4]) (using TLSv1.2 with cipher DHE-RSA-AES128-SHA (128/128 bits)) (No client certificate requested) by sandeen.net (Postfix) with ESMTPSA id 7110963C5FD5; Fri, 24 Oct 2014 17:27:01 -0500 (CDT) Message-ID: <544AD234.3060100@sandeen.net> Date: Fri, 24 Oct 2014 17:27:00 -0500 From: Eric Sandeen MIME-Version: 1.0 To: Stan Hoeppner , xfs@oss.sgi.com Subject: Re: makefs alignment issue References: <544AB289.8010005@hardwarefreak.com> <544AB338.2050905@sandeen.net> <544ACDC4.1070501@hardwarefreak.com> <544AD077.4080305@sandeen.net> X-ASG-Orig-Subj: Re: makefs alignment issue In-Reply-To: <544AD077.4080305@sandeen.net> Content-Type: text/plain; charset=windows-1252 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: sandeen.net[63.231.237.45] X-Barracuda-Start-Time: 1414189621 X-Barracuda-URL: http://192.48.176.25:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.10891 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On 10/24/14 5:19 PM, Eric Sandeen wrote: > On 10/24/14 5:08 PM, Stan Hoeppner wrote: >> >> On 10/24/2014 03:14 PM, Eric Sandeen wrote: > > ... > >>>> Any ideas how to verify what's going on here and fix it?

It seems file alignment isn't a big problem after all as the controllers are doing relatively few small destages, about 1/250th of full stripe destages. And some of these are journal and metadata writes. ... >>> The 350 streams are written to 350 preallocated files in parallel. >> >> And they layout of those files are?

SG0, SG1, and SG2 are the large, medium, and small file counts respectively.

The directory structure is setup so that each group directory has one subdir per stream and multiple files which are written in succession as they fill, and we start with the first file in each directory. SG0 has two streams/subdirs, SG1 has 50, and SG2 has 350. Write stream rates: SG0 2@ 94.0 MB/s, SG1 50@ 2.4 MB/s SG2 350@ 0.14 MB/s This is 357 MB/s aggregate targeted at a 12+1 RAID5 or 12+2 RAID6, the former in this case. In either case we can't maintain this rate. A ~36-45 hour run writes all files once. During this duration we see the controller go into congestion hundreds of times. Wait goes up, bandwidth down, and we drop application buffers because they're on a timer. If we can't write a buffer in X seconds we drop it. The directory/file layout indicates highly variable AG access patterns throughout the run, thus lots of AG-to-AG seeking, thus seeking lots of platter surface all the time. It also indicates large sweeps of the actuators when concurrent file accesses are in low and high numbered AGs. And this tends to explain the relatively stable throughput some of the time with periods of high IO wait and low bandwidth at other times. Too much seek delay with these latter access patterns. I haven't profiled the application to verify which files are written in parallel at a given point in the run, but I think that would be a waste of time given the file/AG distribution we see above. And I don't have enough time left on my contract to do it anyway. I've can attach tree or 'ls -lavR' output if that would help paint a clearer picture of ho the filesystem is organized.

With tonight's kernel + xfs-oss/for-next and a lot of "-v 3" arguments, it went like this: 1) xfsdump'ed my v5/finobt /. Exit code was SUCCESS, return code was SUCCESS. 2) Did something like `gzip -dc dump.0.gz | xfsrestore -t -`. Exit code was SUCCESS, return code was SUCCESS. 3) Did a `find / -mount -type f -exec md5sum {} \; | tee ~/MD5SUMS` 4) Zeroed /dev/sda4, then made a new FS using `mkfs.xfs -m crc=1,finobt=1 /dev/sda4` # (12 GB) 5) xfsrestore'd the v5/finobt / from another partition. Exit code was SUCCESS, return code was SUCCESS. xfsrestore claimed 19494 directories and 268540 or 298540 files. I thought I read 268540 lines for the MD5SUMS file and 298540 from the xfsrestore output. Eyes must be blurring... 6) Tried to reboot into the v5/finobt /. No /etc/inittab, cannot boot. In fact, if files were restored to /etc, they were nested fairly deeply. 7) From another partition, I ran commands like this: find /mnt/v5xfs -mount -type d | wc -l # 19494 directories find /mnt/v5xfs -mount -type f | wc -l # 118417 files 8) Tried the restore onto a non-XFS filesystem. Still it restored all 19494 directories but only 118417 files. This was somewhat disconcerting to have all that SUCCESS and have it followed by failure. I'm rather puzzled that the backups had different results last time. AFAIK, writes were completing before block issues were fixed, they just took an extremely long time when enough I/O was built up. Anyway, that was an update, and I'll try some tar restore results next time. tar is fairly demonstrative about errors, though. If the backup went OK, then the restore should go OK as well. Good luck!

That there is a ratio of 31 is a verified fact, and so is that the reported size of the block device was 100TB. Much of the rest is arithmetic and I indicated that there were was some guesswork involved, mostly assuming that those reported facts were descriptive of the actual configuration. Simply for brevity I did not also point out specifically that the reported facts that =ABhigh r_await(160) and w_await(200000)=BB and the "Subject:" =ABvery high Average Read/Write Request Time=BB contributed to indicating a (big) issue with the storage layer. and that the presumed width of the array of 32 is congruentn with typical enclosure capacities. Another poster went far further in guesswork, and stated what I was describing as guesses instead as obvious facts: http://oss.sgi.com/archives/xfs/2014-10/msg00337.html > As others mentioned this isn't an XFS problem. The problem is that > your RAID geometry doesn't match your workload. Your very wide > parity stripe is apparently causing excessive seeking with your > read+write workload due to read-modify-write operations. and went on to make a whole discussion wholly unrelated to XFS based on that: > To mitigate this, and to increase resiliency, you should > switch to RAID6 with a smaller chunk. If you need maximum > capacity make a single RAID6 array with 16 KiB chunk size. > This will yield a 496 KiB stripe width, increasing the odds > that all writes are a full stripe, and hopefully eliminating > much of the RMW problem. =20 > A better option might be making three 10 drive RAID6 arrays > (two spares) with 32 KiB chunk, 256 KiB stripe width, and > concatenating the 3 arrays with mdadm --linear. The above assumptions and offtopic suggestions have been unquestioned; by myself too, even if I disagree with some of the recommendations, also as I think them premature because we don't know what the requirements really are beyond what can be guessed from =ABthe reported information=BB. That's also why I suggested to continue the discussion on the Linux RAID list. The guess that the filesystem was meant to be an object store is also based on a verified fact: > if the device name "/data/fhgfs/fhgfs_storage" is dedscriptive, > this "brave" RAID5 set is supposed to hold the object storage > layer of a BeeFS Also BP did not initially question my analysis of the 100TB filesystem case, but asked a wholly separate question asking to explain this aside: > the object storage layer of a BeeFS highly parallel filesystem, > and therefore will likely have mostly-random accesses. To that question I provided a reasonable and detailed *technical* explanation, both as to the specific case and in general, and linking it to both the original question by QH and to the list topic which is XFS. As a reminder this thread seems to me to contain 3 distinct even if connected *technical* topics: * Whether the report about the 100TB RAID based XFS filesystem contained evidence indicating an XFS issue or a RAID issue; this was introduced by QH. * Whether concurrent randomish read-writes tend to be the workload observed by object stores in large parallel HPC systems; this was introduced by BP. * Whether concurrent randomish read-write would happen in the use of that specific filesystem as an object store; this was introduced by myself to link QH's original question to BP's new question, because strictly speaking BP's question seemed to me offtopic in the XFS mailing list. Then BP seemed to switch topics again by mentioning 1 and 2 threaded read-write in the context of the general issue of the access patterns of large parallel HPC filesystem object stores, and that seemed strange to me, as I commented, so I ignore it. > appropriate response would be to ask the OP to describe their > workload and storage in more detail Indeed, and I suggested to move the discussion to the Linux RAID mailing list for that purpose, because the evidence quoted above seemed to indicate that a 32-wide RAID5 was involved, as in: > This issue should be moved to the 'linux-raid' mailing list as > from the reported information it has nothing to do with XFS. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D This left free QH to report more information as someone asked to indicate the issue was relevant more to the XFS list than to the Linux RAID list, or to move to the Linux RAID list with more details. Again, the suggestion to continue the discussion in another list that seemed more useful to QH was based on simple inferences based on 3 reported facts: 31 ratio, 100TB size, "fast" single threaded speed vs. slow concurrent read/write speeds (and the concurrent high wait times). You and BP are entitled to think those are not good guesses (just as SH instead took them as good ones) and it would be interesting if you provided substantive reason why the suggestion to continue the discussion in the Linux RAID list was inappropriate, but you haven't contributed any other than your say-so. Also while suggestions have been made to QH to provide more details and/or move the discussion to the Linux RAID list by different people, notably this has not happened yet.

I forgot to ask (and you forgot to report...!) what version of xfsprogs you're using.... Currently, blkid_get_topology() in xfsprogs does: /* * Blkid reports the information in terms of bytes, but we want it in * terms of 512 bytes blocks (just to convert it to bytes later..) * * If the reported values are the same as the physical sector size * do not bother to report anything. It will just cause warnings * if people specify larger stripe units or widths manually. */ val = blkid_topology_get_minimum_io_size(tp); if (val > *psectorsize) *sunit = val >> 9; val = blkid_topology_get_optimal_io_size(tp); if (val > *psectorsize) *swidth = val >> 9; so in your case sunit probably wouldn't get set (can you confirm with # blockdev --getpbsz that the physical sector size is also 512?) But the optimal size is > physical sector so swidth gets set. Bleah... can you just collect all of: # blockdev --getpbsz --getss --getiomin --getioopt for your underlying devices, and I'll dig into how xfsprogs is behaving for those values. I have a hunch that we should be ignoring stripe units of 512 even if the "width" claims to be something larger. -Eric From g.fernandez@tbs-education.fr Sat Oct 25 10:57:29 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.9 required=5.0 tests=HTML_MESSAGE,MISSING_HEADERS autolearn=no version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id 924137F5F for ; Sat, 25 Oct 2014 10:57:29 -0500 (CDT) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay1.corp.sgi.com (Postfix) with ESMTP id 601178F8049 for ; Sat, 25 Oct 2014 08:57:29 -0700 (PDT) X-ASG-Debug-ID: 1414252644-04bdf038cf3e0380001-NocioJ Received: from mx.tbs-education.fr (mx.tbs-education.fr [212.99.31.10]) by cuda.sgi.com with ESMTP id mchrNVV1Eiy1Qf2d; Sat, 25 Oct 2014 08:57:25 -0700 (PDT) X-Barracuda-Envelope-From: g.fernandez@tbs-education.fr X-Barracuda-Apparent-Source-IP: 212.99.31.10 Received: from mx.tbs-education.fr (unknown [127.0.0.1]) by IMSVA (Postfix) with ESMTP id 678387864C; Sat, 25 Oct 2014 17:57:33 +0200 (CEST) Received: from SP-BDDEXCH-2.DE-Enseignement.local (unknown [192.168.81.58]) by mx.tbs-education.fr (Postfix) with ESMTP id 196D47864A; Sat, 25 Oct 2014 17:57:33 +0200 (CEST) Received: from SP-BDDEXCH-1.DE-Enseignement.local ([fe80::806:957e:5193:d3e5]) by SP-BDDEXCH-2.DE-Enseignement.local ([fe80::d5d3:c6a8:5d96:b652%17]) with mapi id 14.03.0123.003; Sat, 25 Oct 2014 17:57:23 +0200 From: =?iso-8859-1?Q?FERNANDEZ_Genevi=E8ve?= CC: "w.melissa@yahoo.com" , "w.merv@yahoo.com" , "w.mia74@yahoo.com" , "w.rozema@rocmn.nl" , "w.sam.warner@gmail.com" , "w.sandra90@yahoo.com" , "w.sandras@yahoo.com" , "w.taylor@yahoo.com" , "w.taylor_jr@yahoo.com" , "w.tduley@yahoo.com" , "w.vandenbrink@rocmn.nl" , "w.vandervalk@rocmn.nl" , "w.vanessa45@yahoo.com" , "w.vanlaarhoven@rocmn.nl" , "w.vanloon@rocmn.nl" , "w.vaughn16@yahoo.com" , "wade.lawrence@aol.com" , "wade.lowe@msn.com" , "wade.mcbride@cs.com" , "websitevrageneducatie@rocmn.nl" , "wenning@kvsa.nl" , "wesley.lagerwey@knvb.nl" , "wieckowski@mwconstruction.com.pl" , "wieckowski@sil-pro.pl" , "willemjanvanloon@3dprintconsult.nl" , "william@netproteus.net" , "williams@soderhamn.se" , "wina_jozef_keren@yahoo.com" , "www.karami1373@yahoo.com" , "xfs@oss.sgi.com" , "xfs-masters@oss.sgi.com" , "xtremeevents@rocmn.nl" , "y.degrunt@rocmn.nl" , "y.helmich@gmail.com" , "y.hogt@rocmn.nl" , "y.leupen@rocmn.nl" , "yuk.lau@ousd.k12.ca.us" , "yvonne.hogt@award.nl" , "zahrohnuriah@yahoo.com" , "zorgsymposium@rocmn.nl" Subject: Helpdesk support.

Just a hunch? :) If the same interface is used for Linux logical block devices (md, dm, lvm, etc) and hardware RAID, I have a hunch it may be better to determine that, if possible, before doing anything with these values. As you said previously, and I agree 100%, a lot of RAID vendors don't export meaningful information here. In this specific case, I think the RAID engineers are exporting a value, 1 MB, that works best for their cache management, or some other path in their firmware. They're concerned with host interface xfer into the controller, not the IOs on the back end to the disks. They don't see this as an end-to-end deal. In fact, I'd guess most of these folks see their device as performing magic, and it doesn't matter what comes in or goes out either end. "We'll take care of it." I don't know what underlying SCSI command is used for populating optimal_io_size. I'm guessing this has different meaning for different folks. You say optimal_io_size is the same as RAID width. Apply that to this case: hardware RAID 60 LUN, 4 arrays 16+2 RAID6, 256 KB stripe unit, 4096 KB stripe width 16 MB LUN stripe width optimal_io_size = 16 MB Is that an appropriate value for optimal_io_size even if this is the RAID width? I'm not saying it isn't. I don't know. I don't know what other layers of the Linux and RAID firmware stacks are affected by this, nor how they're affected.

What I'm trying to do is use parallel dd w/O_DIRECT to write 44 files in parallel to 44 directories, thus all 44 AGs, in one test, then write 44 files to one dir, one AG, in another test. The purpose of this quick/dirty exercise is to demonstrate throughput differences due to full platter seeking in the former case and localized seeking in the latter case. But of course the problem I'm running into in the single directory case is that the filestreams allocator starts writing all of the 44 files into the appropriate AG, but then begins allocating extents for each file in other AGs.

When a parity array's throughput drops 2 orders of magnitude, from ~1.5 GB/s to 100 MB/s, RMW is historically the most likely cause, especially with such a wide stripe.

XFS is a layer of the Linux IO stack, and none of these layers exist in isolation.

I don't know if this is a cultural thing or other, but that's the way they seem to operate. There is rarely interaction with them, no follow ups, no additional information provided. So I tend to give them many ideas on the obvious path to work with in my reply, after asking for additional information, which will likely never arrive. Moving the thread to linux-raid wouldn't help. And I'm sure you know Dave didn't come down on you due to the guesswork in your posts, but because of your delivery style, and attitude and behavior towards others. It seems the latter prompted his critique of the former.

That turns it on (if it's not enabled by default these days). I need to turn off the behavior I'm seeing, whether it's due to the filestreams allocator or default inode64. Then again it may not be possible to turn it off... Anyone have other ideas on how to accomplish my goal? Parallel writes to a single AG on the outer platter edge vs the same to all AGs across the entire platter? I'm simply trying to demonstrate the differences in aggregate bandwidth due to the extra seek latency of all AGs case.

Obviously this removes block allocation contention from your experiment, but it's not clear if that's relevant to your test. If I create a smaller, but analogous fs to yours, I seem to get this behavior from just doing an fallocate of each file in advance. E.g., Create directory 0, fallocate 44 files all of which end up in AG 0. Create directory 1, fallocate 44 files which end up in AG 1, etc. >From there you can do direct I/O overwrites to 44 files across each AG or 44 files in any single AG.

I figured preallocating would get me what I want but I've never used fallocate, nor dd into fallocated files. Is there anything special required here with dd, or can I simply specify the filename to dd, and make sure bs + count doesn't go beyond EOF?

Deja vu. This is an isochronous RAID array you are having trouble with, isn't it?

I'm not saying it isn't. I don't know. I don't know what > other layers of the Linux and RAID firmware stacks are affected by this, > nor how they're affected. yup, i'd expect minimum = 4MB (i.e stripe unit 4MB so we align to the underlying RAID6 luns) and optimal = 16MB for the stripe width (and so with swalloc we align to the first lun in the RAID0). This should be passed up unchanged through the stack if none of the software layers are doing other geometry modifications (e.g. more raid, thinp, etc).

This is of course defeating the purpose of the tests. That's caused by allocator contention. When you try to write 44 files to the same dir in parallel, they'll all start with the same target AG, but then when one thread is allocating into AG 43 and has the AG locked, a second attempt to allocate to than AG will see the AG locked and so it will move to find the next AG that is not locked. Remember, AGs were not originally designed for confining physical locality - they are designed to allow allocator parallelism. Hence once the file has jumped to a new AG it will try to allocate sequentially from that point onwards in that same AG, until either ENOSPC or further contention. Hence with a workload like this, if the writes continue for long enough each file will end up finding it's own uncontended AG and hence mostly end up contiguous on disk and not getting blocked waiting for allocation on other files. When you have as many writers as there are AGs, however, such a steady state is generally not possible as there will always be files trying to write into the same AG. As it is, filestreams is not designed for this sort of parallel workload. filestreams is designed to separate single threaded streams of IO into different locations, not handle concurrent writes into multiple files in the same directory. As it is, the inode64 will probably demonstrate exactly the same behaviour because it will start by trying to write all the files to the same AG and hence hit allocator contention, too.

At minimum 4MB how does that affect journal writes which will be much smaller, especially with a large file streaming workload, for which this setup is appropriate? Isn't the minimum a hard setting?

But they sure do come in handy when used this way with preallocated files.

That's exactly what xfs_bmap was showing. Some files had extents in 3-4 AGs, some in 8 or more AGs. > As it is, filestreams is not designed for this sort of parallel > workload. filestreams is designed to separate single threaded > streams of IO into different locations, not handle concurrent writes > into multiple files in the same directory. Right. I incorrectly refered to the filestreams allocator as I didn't know of the inode64 congestion control mechanism at that time. I simply had recalled one of your emails where you and Christoph were discussing mods to the filestreams allocator, and the file pattern to the AGs looked familiar. > As it is, the inode64 will probably demonstrate exactly the same > behaviour because it will start by trying to write all the files to > the same AG and hence hit allocator contention, too. I was using the inode64 allocator, and yes, it did. Brian saved my bacon as I wanted to use preallocated files but didn't know exactly how. I knew all their extents would be in the AG I wanted them in, given the way I intended to do it. And doing this demonstrated what I anticipated. Writing 2GB into each of 132 files with 132 parallel dd processes with O_DIRECT, 264GB total, I achieved: AG0 only 1377 MB/s AGs 0-43 767 MB/s Due to the nature of the application, we should be able to distribute the files in such a manner that only 1 or 2 adjacent AGs are being accesses concurrently. This will greatly reduce head seeking, increasing throughput, as demonstrated above. All thanks to the allocation group architecture of XFS. We'd not be able to do this with any other filesystem AFAIK.

The location of parity doesn't dtermine that it is isochronous in behaviour or not.

I mentioned this in that > (rather lengthy) previous reply. Right, but if you had a 768k stripe width and a 1MB cache segment size, a cache segment operation would require two stripe widths to be operated on, and only one would be a whole stripe width. hence the possibility of doing more IOs than are necessary to populate or write back cache segments. i.e. it's a potential reason for why the back end disks didn't have anywhere near the expected seek capability they were supposed to have.... > >> optimal_io_size.

No, "minimum_io_size" is for "minimum *efficient* IO size" not the smallest supported IO size. The smallest supported IO sizes and atomic IO sizes are defined by hw_sector_size, physical_block_size and logical_block_size.

Areca). I've started seeing kernel crashes in October, as per the netconsole logs attached, on two of the machines (one HP, one Supermicro). The traces look quite similar, the machine in question cannot write anything to its own filesystem when this happens so the logs are made over the network. The XFS filesystem is not root (that's ext4), but one for data (OS containers), on both machines. When I run xfs_check and xfs_repair on the filesystem after the kernel crash & reboot, no issue is ever found. This may very well have nothing to do with XFS kernel code you wrote and maintain, but in that case, could you, from looking at the traces, tell me whether it maybe looks like something issue related to vm/paging just ending up in XFS related code path?

Hi,

I'm running OpenVZ (= OS container) kernel variant of RHEL6 kernel on
several amd64 mac= hines by different manufacturers (HP and Supermicro)
and differen= t RAID cards (HP and Areca).

I've started seei= ng kernel crashes in October, as per the netconsole
logs attached= , on two of the machines (one HP, one Supermicro). The
traces loo= k quite similar, the machine in question cannot write
anything to= its own filesystem when this happens so the logs are made
over t= he network. The XFS filesystem is not root (that's ext4), but
one for data (OS containers), on both machines. When I run xfs_check
=
and xfs_repair on the filesystem after the kernel crash & reboot, = no
issue is ever found.

This may very we= ll have nothing to do with XFS kernel code you wrote
and maintain= , but in that case, could you, from looking at the traces,
tell m= e whether it maybe looks like something issue related to
vm/pagin= g just ending up in XFS related code path?

I'm= happy to test any suggestions/fixes for this if it is XFS related.

Thank you,

However for large filesystems (which are mainly those that require high performance) the ability to shrink would be really needed. People usually do not have double the space so to move files to a smaller XFS filesystem, and the inability of XFS to shrink forbids major reorganizations of the storage systems. Currently, for that reason I use ext4. Performance is still decent and flexibility is higher due to the ability to shrink, but I would use XFS if it could shrink. I suppose shrinking ability is not even planned, is it? Thank you S.

It's the lack of buffering/blocking that makes it isochronous. Above I was referring to something you said last year: http://oss.sgi.com/archives/xfs/2013-06/msg00981.html "And at the other end of the scale, isochronous RAID arrays tend to have dedicated parity disks so that data read and write behaviour is deterministic and therefore predictable from a high level...." >>> FWIW, do your problems go away when you make you hardware LUN width >>> a multiple of the cache segment size? >> >> Hadn't tried it.

That's a very good point. And would be performance suicide for a vendor pushing 224 drive arrays packed w/7.2 drives. I don't think that's what's happening here though, as testing with 132 parallel dd threads shows 1375 MB/s to the outer most AG. Peak single thread buffered dd write is ~1500 - 1800 MB/s depending on file size, etc. So with the right parallel workload we can achieve pretty close t peak LUN throughput. >>>> optimal_io_size.

So would it be better for RAID vendors to simply populate these values with zeros instead of values that don't match the LUN geometry, as is the case with the arrays I've been working with? BTW, where/how are these values obtained? Are they returned to a SCSI inquiry? If so, which SCSI command?

Prior to this patch, we reset only sunit *or* swidth, if either was equal to physical block size, but not necessarily both. Change the heuristic so that if either the discovered sunit or the discovered swidth is physical block size, we reset *both* to zero and ignore the geom completely. While we're at it, don't pass &dummy in for multiple arguments to blkid_get_topology(); that'll mean that inside the function, the last assignment wins, and could lead to unexpected results.

Not formally planned, there are bits and pieces out there (i.e. the inode mover) which are part of what it might take to achieve a shrinker. Another option, rather than fs shrinking, is to use the dm-thinp target, which would allow you to allocate a large-but-sparse block device, create a very large filesystem on that, and add or remove storage as needed.

Yes, I think you're right, but my point is this is a kernel which we don't maintain. Anyway, I don't know for sure offhand what this could be; upstream ef5d437f71afdf4afdbab99213add99f4b1318fd looks related, but TBH I'm not sure if it's specific to S390. -Eric From david@fromorbit.com Tue Oct 28 19:23:01 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay1.corp.sgi.com [137.38.102.111]) by oss.sgi.com (Postfix) with ESMTP id BE6C17F37 for ; Tue, 28 Oct 2014 19:23:01 -0500 (CDT) Received: from cuda.sgi.com (cuda1.sgi.com [192.48.157.11]) by relay1.corp.sgi.com (Postfix) with ESMTP id 8EE968F8035 for ; Tue, 28 Oct 2014 17:22:58 -0700 (PDT) X-ASG-Debug-ID: 1414542175-04bdf038d04e9e80001-NocioJ Received: from ipmail06.adl6.internode.on.net (ipmail06.adl6.internode.on.net [150.101.137.145]) by cuda.sgi.com with ESMTP id z4CMAtCBLrvgdhXU for ; Tue, 28 Oct 2014 17:22:56 -0700 (PDT) X-Barracuda-Envelope-From: david@fromorbit.com X-Barracuda-Apparent-Source-IP: 150.101.137.145 X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: AgdfAAMyUFR5LbBUPGdsb2JhbABcgw6BLIc9sxsGlUeFagICAQECgR0XAQEBAQEGAQEBATg7hAMBAQQ6HCMQCAMOCgklDwUlAwcaE4hAxTUBAQEBBgEBAQEeGIYdilQHgy2BHgWdZ4Eyg0mHc4Imiy8pL4JLAQEB Received: from ppp121-45-176-84.lns20.syd7.internode.on.net (HELO dastard) ([121.45.176.84]) by ipmail06.adl6.internode.on.net with ESMTP; 29 Oct 2014 10:52:55 +1030 Received: from dave by dastard with local (Exim 4.80) (envelope-from ) id 1XjH2L-00041M-A0; Wed, 29 Oct 2014 11:22:53 +1100 Date: Wed, 29 Oct 2014 11:22:53 +1100 From: Dave Chinner To: Brian Foster Cc: xfs@oss.sgi.com Subject: Re: [PATCH v5] xfs: rework zero range to prevent invalid i_size updates Message-ID: <20141029002253.GE16186@dastard> X-ASG-Orig-Subj: Re: [PATCH v5] xfs: rework zero range to prevent invalid i_size updates References: <1413824781-10733-1-git-send-email-bfoster@redhat.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <1413824781-10733-1-git-send-email-bfoster@redhat.com> User-Agent: Mutt/1.5.21 (2010-09-15) X-Barracuda-Connect: ipmail06.adl6.internode.on.net[150.101.137.145] X-Barracuda-Start-Time: 1414542175 X-Barracuda-URL: http://192.48.157.11:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 X-Barracuda-Spam-Score: 0.00 X-Barracuda-Spam-Status: No, SCORE=0.00 using per-user scores of TAG_LEVEL=1000.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.7 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.3.11007 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On Mon, Oct 20, 2014 at 01:06:21PM -0400, Brian Foster wrote: > The zero range operation is analogous to fallocate with the exception of > converting the range to zeroes.

This now causes xfs/053 to fail, probably because it changes the behaviour to actually write the file and hence change EOF. Can you please check that this is working correctly, and if so submit patches to change xfs/053 to expect the file size to change and contain the correct data?

All the callers of bdev_get_queue() including blk_get_backing_dev_info() assume that bdev_get_queue() may return NULL and implement NULL handling; however, bdev_get_queue() requires the passed in block_device is opened and attached to its gendisk. Because an active gendisk always has a valid request_queue associated with it, bdev_get_queue() can never return NULL and neither can blk_get_backing_dev_info(). Make it clear that neither of the two functions can return NULL and remove NULL handling from all the callers.

E.g., it attempts to allocate zeroed blocks over the range specified by the caller. The XFS implementation kills all delalloc blocks currently over the aligned range, converts the range to allocated zero blocks (unwritten extents) and handles the partial pages at the ends of the range by sending writes through the pagecache. The current implementation suffers from several problems associated with inode size. If the aligned range covers an extending I/O, said I/O is discarded and an inode size update from a previous write never makes it to disk. Further, if an unaligned zero range extends beyond eof, the page write induced for the partial end page can itself increase the inode size, even if the zero range request is not supposed to update i_size (via KEEP_SIZE, similar to an fallocate beyond EOF). The latter behavior not only incorrectly increases the inode size, but can lead to stray delalloc blocks on the inode. Typically, post-eof preallocation blocks are either truncated on release or inode eviction or explicitly written to by xfs_zero_eof() on natural file size extension. If the inode size increases due to zero range, however, associated blocks leak into the address space having never been converted or mapped to pagecache pages. A direct I/O to such an uncovered range cannot convert the extent via writeback and will BUG(). For example: $ xfs_io -fc "pwrite 0 128k" -c "fzero -k 1m 54321" ... $ xfs_io -d -c "pread 128k 128k" If the entire delalloc extent happens to not have page coverage whatsoever (e.g., delalloc conversion couldn't find a large enough free space extent), even a full file writeback won't convert what's left of the extent and we'll assert on inode eviction. Rework xfs_zero_file_space() to avoid buffered I/O for partial pages. Use the existing hole punch and prealloc mechanisms as primitives for zero range. This implementation is not efficient nor ideal as we writeback dirty data over the range and remove existing extents rather than convert to unwrittern. The former writeback, however, is currently the only mechanism available to ensure consistency between pagecache and extent state. Even a pagecache truncate/delalloc punch prior to hole punch has lead to inconsistencies due to racing with writeback. This provides a consistent, correct implementation of zero range that survives fsstress/fsx testing without assert failures. The implementation can be optimized from this point forward once the fundamental issue of pagecache and delalloc extent state consistency is addressed.

E.g., it attempts to allocate zeroed blocks over the range specified by the caller. The XFS implementation kills all delalloc blocks currently over the aligned range, converts the range to allocated zero blocks (unwritten extents) and handles the partial pages at the ends of the range by sending writes through the pagecache. The current implementation suffers from several problems associated with inode size. If the aligned range covers an extending I/O, said I/O is discarded and an inode size update from a previous write never makes it to disk. Further, if an unaligned zero range extends beyond eof, the page write induced for the partial end page can itself increase the inode size, even if the zero range request is not supposed to update i_size (via KEEP_SIZE, similar to an fallocate beyond EOF). The latter behavior not only incorrectly increases the inode size, but can lead to stray delalloc blocks on the inode. Typically, post-eof preallocation blocks are either truncated on release or inode eviction or explicitly written to by xfs_zero_eof() on natural file size extension. If the inode size increases due to zero range, however, associated blocks leak into the address space having never been converted or mapped to pagecache pages. A direct I/O to such an uncovered range cannot convert the extent via writeback and will BUG(). For example: $ xfs_io -fc "pwrite 0 128k" -c "fzero -k 1m 54321" ... $ xfs_io -d -c "pread 128k 128k" If the entire delalloc extent happens to not have page coverage whatsoever (e.g., delalloc conversion couldn't find a large enough free space extent), even a full file writeback won't convert what's left of the extent and we'll assert on inode eviction. Rework xfs_zero_file_space() to avoid buffered I/O for partial pages. Use the existing hole punch and prealloc mechanisms as primitives for zero range. This implementation is not efficient nor ideal as we writeback dirty data over the range and remove existing extents rather than convert to unwrittern. The former writeback, however, is currently the only mechanism available to ensure consistency between pagecache and extent state. Even a pagecache truncate/delalloc punch prior to hole punch has lead to inconsistencies due to racing with writeback. This provides a consistent, correct implementation of zero range that survives fsstress/fsx testing without assert failures. The implementation can be optimized from this point forward once the fundamental issue of pagecache and delalloc extent state consistency is addressed.

The problem as that the AGFL was not being correctly rebuilt due to a very particular freespace pattern in AG 0 which required free blocks in the AGFL to populate an empty AGFL. reapir silently ignored this error, so it triggered allocation corruption errors when the same AGFL fixup attempt failed on a mounted filesystem. The fix is relatively straight forward, as is the fixes to the tracing code that I had to make before i could track down the issue. -Dave.

If the freespace information is laid out just right, we end up having to allocate free space for the AGFL blocks. If the size of the free space we allocate from is larger than the space we need, then we have to insert the remainder back into the freespace btree. For the by-size tree, this means we are likely to be removing a record from one leaf, and then inserting the remainder - a smaller size - into another leaf. The issue is that the leaf blocks to the left of the original leaf block we removed the extent record from are full and hence require a split to insert the new record. That, of course, requires a free block in the AGFL to allocate from, and now we have a chicken and egg situation: there are no free blocks in the AGFL because we are setting it up. As a result, setting up the free list silently fails, leaving the freespace btrees in an inconsistent state and the AGFL in question empty. When the filesystem is next mounted, the first allocation from that AGF results in attempting to fix the AGFL, and it then does exactly the same thing as the repair code, fails to allocate a block during the split and fails. This results in an immediate shutdown because the transaction doing the allocation is dirty by this stage. The fix for the problem is to make repair handle rebulding the btree differently. If we leave ispace for a couple of records in each btree leaf and node, there is never a need for a split to occur when initially setting up the AGFL. This results in repair doing the right thing, and hence the runtime problems after mount don't occur. Further, add error checking the the AGFL setup code and abort repair if we have a failure to correctly set up the AGFL so we catch this problem at repair time, not mount time...

I think there might be something else wrong with your system.

What's the stack trace associated with that? If there's none,
what's the output of 'echo w > /proc/sysrq-trigger' in dmesg= ?

Cheers,

Same testing in same machine (just different kernel).=

3.18-rc2:
xfsdump will hang (the test.xfsdump.gz size= stop around 57M)

3.17.1 (with 2 patches):
xfsdump ge= nerate the dump file, but xfsrestore can't restore all files from the d= ump file.
I think the dump is corrupted, can't restore it= also in kernel 3.16.5.

3.16.5:
everything work fine.

Then using thinp would mess up all the disk layout, basically replacing the XFS allocator, which most likely would decrease performances significantly. And then the thinp code itself is a medium performance thing and I don't think it can keep up with XFS performances, so that would presumably be a hard bottleneck. All this would result in a performance almost certainly lower than ext4. Thanks S.

Right, I'm sorry, the source code patch on vanilla kernel is l= inked from
and
for the two kernel versions.

xfs.aops.c differs a bit between the older and the = newer version (released 6 months apart), but both kernels crash.=C2=A0

OpenVZ d= evs unfortunately don't publish their git tree anymore.

I don't know what's in "2.6.32-openvz-amd64" so can't= help much.

What is at line 86 of xfs_aops.c in that kernel?

<= /div>
Stefan is right in that it's the line
bh =3D head = =3D page_buffers(page);
from=C2=A0
xfs_count_page_s= tate()

Eric, thanks for the pointer to=C2=A0ef= 5d437f71afdf4afdbab99213add99f4b1318fd, I'll raise it with OpenVZ devs = or with RHEL so the bug trickles downstream to OpenVZ.

Metadata is also accounted to quotas (e.g. to the user who owns the directory) and so even if data usage is identical the metadata can still vary. I see these test give small variations quite frequently, but they are are usually only quite small (a handful of blocks) so I've never really worried about it too much.

Does it just fix the hang issue or fix the = dump corrupted issue?

I just clone the git repo and checkout x= fs-fixes-for-3.18-rc3, build it again.
Now, xfsdump won't hang= , but still can't restore the dump file correctly.
The result = just same as kernel 3.17.1.

We had a chat a while ago about the possibility of stale data exposure after a crash at just the right time between delalloc extent conversion and writeback. That test was intended to expose that problem in sort of a hacky way by virtue of the partial writeback that might occur due to file allocation operations. Hole punch happens to expose this problem, fzero is now allocated via hole punch and thus exposes it as well. I think I called this out as a side effect in one of the previous versions of this patch. As far as xfs/053 goes, it just uses falloc operations to reproduce the stale data problem. Now that I think of it, I could look into using something like sync_file_range() to reproduce in xfs/053 instead. Either way, I would expect xfs/053 to fail as such until we address the general extent conversion/writeback problem. I sent the test at the time as I simply happened to come across it and wanted to make sure the test case wasn't lost (as opposed to it being any kind of regression test for fzero).

It's not a directory you want to salvage, but the files within it. If they reside on sdc1 you're out of luck without using data recovery tools. If they reside on sdb1, sdd1, or sde1, then running xfs_repair might make the FS mountable and get you access to them again. That's assuming LVM is still running with one drive gone, or will still assemble the concatenation with one drive missing. I don't use LVM.

Hi folks,

The following two patches fix a repair rebuild issue that was
reported to me. xfs_repair would appear to succeed, but subsequent
runs would report a freespace mismatch and then on mount trigger
a corruption error on the first allocation from AG 0.

The problem as that the AGFL was not being correctly rebuilt due to
a very particular freespace pattern in AG 0 which required free
blocks in the AGFL to populate an empty AGFL. reapir silently
ignored this error, so it triggered allocation corruption errors
when the same AGFL fixup attempt failed on a mounted filesystem.

The fix is relatively straight forward, as is the fixes to the
tracing code that I had to make before i could track down the issue.

There was a real world scenario of this, right? Any idea of the configuration details (e.g., raid layout) that resulted in an increased optimal I/O size but not minimum I/O size? This seems reasonable to me and the code looks fine, save a trailing whitespace instance below. I'm just curious if there are any weird corner cases where there's value in the reported optimal I/O size or the real world situation was just noise. > Prior to this patch, we reset only sunit *or* swidth, > if either was equal to physical block size, but not > necessarily both. > > Change the heuristic so that if either the discovered > sunit or the discovered swidth is physical block size, > we reset *both* to zero and ignore the geom completely. > > While we're at it, don't pass &dummy in for multiple > arguments to blkid_get_topology(); that'll mean that > inside the function, the last assignment wins, and could > lead to unexpected results. > > Reported-by: Stan Hoeppner > Signed-off-by: Eric Sandeen > --- > > diff --git a/mkfs/xfs_mkfs.c b/mkfs/xfs_mkfs.c > index 4546e35..a0fed31 100644 > --- a/mkfs/xfs_mkfs.c > +++ b/mkfs/xfs_mkfs.c > @@ -410,21 +410,27 @@ static void blkid_get_topology( > *lsectorsize = val; > val = blkid_topology_get_physical_sector_size(tp); > *psectorsize = val; > + val = blkid_topology_get_minimum_io_size(tp); > + *sunit = val; > + val = blkid_topology_get_optimal_io_size(tp); > + *swidth = val; > > /* > - * Blkid reports the information in terms of bytes, but we want it in > - * terms of 512 bytes blocks (just to convert it to bytes later..) > - * > * If the reported values are the same as the physical sector size > - * do not bother to report anything.

You've created an XFS filesystem atop a concatenation of no= n-redundant
drives so this condition should not be unexpected.=A0 It's not a direct= ory
you want to salvage, but the files within it.=A0 If they reside on sdc1
you're out of luck without using data recovery tools.=A0 If they reside= on
sdb1, sdd1, or sde1, then running xfs_repair might make the FS mountable and get you access to them again.

That's assuming LVM is still running with one drive gone, or will still=
assemble the concatenation with one drive missing.=A0 I don't use LVM.<= br>

I suppose the only interesting side effect is that the alloc btrees might require a bit more space after repair than before. I wonder if we need to take that into consideration here for certain cases. E.g., does this have ramifications for running repair on a clean, but completely full fs, or should that be generally handled by the existence of reserved blocks?

In general, it shouldn't be an issue. It is extremely rare for a free space btree to be entirely compact - it currently only happens when repair runs, and the first insert at each leaf triggers splits and so after a short runtime will no longer be compact. Hence it is almost always going to be the case that the btree is smaller after repair than it was before.... I can see that it might cause an issue at maximally sized filesystems with worst case free space fragmentation, but given the runtime of repair of such a filesystem is probably measured in months and in hundreds of petabytes of RAM I'm not really concerned about that right now. > > A couple minor nits below... > > > Reported-by: Barkley Vowk > > Signed-off-by: Dave Chinner > > --- > > repair/phase5.c | 44 +++++++++++++++++++++++++++++++++++--------- > > 1 file changed, 35 insertions(+), 9 deletions(-) > > > > diff --git a/repair/phase5.c b/repair/phase5.c > > index d6d3c6d..3d58936 100644 > > --- a/repair/phase5.c > > +++ b/repair/phase5.c > > @@ -335,11 +335,22 @@ finish_cursor(bt_status_t *curs) > > } > > > > /* > > + * We need to leave some free records in the tree for the corner case of > > + * setting up the AGFL.

From the DIAGNOSTICS section of the xfsdump man page: The message ``xfsdump: WARNING: unable to open directory: ino N: Invalid argument'' can occur with filesystems which are actively being modified while xfsdump is running. This can happen to either directory or regular file inodes - affected files will not end up in the dump, files below affected directories will be placed in the orphanage directory by xfsrestore. This is exactly what you are seeing - files being placed in the orphanage on restore because they appear to have no parent directory inode referencing them. IOWs, you're likely seeing the effect of the filesystem changing while you are running xfsdump, not a bug in xfsdump or xfs_restore.

So, I've done almost exactly the same test locally (I used the 3.18-rc2 tarball) and on both the upstream 3.18-rc2 kernel and my current xfs-fixes-for-3.18-rc3 branch I can't reproduce your problem: $ find /mnt/test -type d |wc -l 3080 $ find /mnt/test |wc -l 51068 $ zcat dump.gz | sudo xfsrestore -p 300 -J - . |grep xfsrestore ..... xfsrestore: reading directories xfsrestore: 3080 directories and 51068 entries processed xfsrestore: directory post-processing xfsrestore: restoring non-directory files xfsrestore: restore complete: 7 seconds elapsed xfsrestore: Restore Status: SUCCESS $ find /mnt/scratch -type d |wc -l 3080 $ find /mnt/scratch |wc -l 51069 $ ls /mnt/scratch dump.gz linux-3.18-rc2 $ Which shows that it's working just fine. I've tried cold cache dumps. I've tried crc enabled filesystems, I've tried a bunch of random permutations, but I cannot get dump/restore to do what you are seeing it do. Whatever problem you are seeing is specific to your system. Hmmm - can you run 'ldd xfsdump' and 'ldd xfsrestore' and paste the output for me? Can you also please run a full test again on a kernel built from the current xfs-fixes-for-3.18-rc3 branch, with full dump/restore debug enabled and send me the output? i.e. $ xfsdump -v debug ... and $ xfsrestore -v debug,tree=nitty ... They ar going to produce a lot of output, so please capture it to files rather than trying to cut/paste output to an email.

I'm confusing now...

in the test VM and one of my machine, rebuild xfsdump/xfsprogs wi= ll make the test work.

In one of my machine, still = got error.

Partition sizes are roughly a 5GB source and 10GB destination.

So there's this many files in the fs:

OK, so on 3.18-rc2:

These are a handful of bytes different.

and the test shows:

A thousand less directories and 20000 less files, which doesn't = make
much sense for a dump that has a few bytes difference in size.

So, I've done almost exactly the same test locally (I used the
3.18-rc2 tarball) and on both the upstream 3.18-rc2 kernel and my
current xfs-fixes-for-3.18-rc3 branch I can't reproduce your
problem:

$=C2=A0 find /mnt/test -type d |wc -l
3080
$=C2=A0 find /mnt/test=C2=A0 |wc -l
51068
$ zcat dump.gz | sudo xfsrestore -p 300 -J - . |grep xfsrestore
.....
xfsrestore: reading directories
xfsrestore: 3080 directories and 51068 entries processed
xfsrestore: directory post-processing
xfsrestore: restoring non-directory files
xfsrestore: restore complete: 7 seconds elapsed
xfsrestore: Restore Status: SUCCESS
$ find /mnt/scratch -type d |wc -l
3080
$ find /mnt/scratch |wc -l
51069
$ ls /mnt/scratch
dump.gz=C2=A0 linux-3.18-rc2
$

Which shows that it's working just fine.=C2=A0 I've tried cold cach= e
dumps. I've tried crc enabled filesystems, I've tried a bunch of random permutations, but I cannot get dump/restore to do what you
are seeing it do. Whatever problem you are seeing is specific to
your system.

Hmmm - can you run 'ldd xfsdump' and 'ldd xfsrestore' and p= aste the
output for me?

Can you also please run a full test again on a kernel built from the
current xfs-fixes-for-3.18-rc3 branch, with full dump/restore debug
enabled and send me the output? i.e.

$ xfsdump -v debug ...

and

$ xfsrestore -v debug,tree=3Dnitty ...

They ar going to produce a lot of output, so please capture it to
files rather than trying to cut/paste output to an email.

Cheers,

Dave.

It' look like no help after rebuild xfsdump/xfsprogs, = it still got the same error for some case.

2014-10-30 16:39 GMT+08:00 Tommy Wu <w= u.tommy@gmail.com>:
I'm confusing now...

in the test VM and one of my machine, rebuild xfsdump/xfsprogs will make= the test work.

In one of my machine, still got err= or.

Partition sizes are roughly a 5GB source and 10GB destination.

So there's this many files in the fs:

OK, so on 3.18-rc2:

These are a handful of bytes different.

and the test shows:

A thousand less directories and 20000 less files, which doesn't = make
much sense for a dump that has a few bytes difference in size.

So, I've done almost exactly the same test locally (I used the
3.18-rc2 tarball) and on both the upstream 3.18-rc2 kernel and my
current xfs-fixes-for-3.18-rc3 branch I can't reproduce your
problem:

$=C2=A0 find /mnt/test -type d |wc -l
3080
$=C2=A0 find /mnt/test=C2=A0 |wc -l
51068
$ zcat dump.gz | sudo xfsrestore -p 300 -J - . |grep xfsrestore
.....
xfsrestore: reading directories
xfsrestore: 3080 directories and 51068 entries processed
xfsrestore: directory post-processing
xfsrestore: restoring non-directory files
xfsrestore: restore complete: 7 seconds elapsed
xfsrestore: Restore Status: SUCCESS
$ find /mnt/scratch -type d |wc -l
3080
$ find /mnt/scratch |wc -l
51069
$ ls /mnt/scratch
dump.gz=C2=A0 linux-3.18-rc2
$

Which shows that it's working just fine.=C2=A0 I've tried cold cach= e
dumps. I've tried crc enabled filesystems, I've tried a bunch of random permutations, but I cannot get dump/restore to do what you
are seeing it do. Whatever problem you are seeing is specific to
your system.

Hmmm - can you run 'ldd xfsdump' and 'ldd xfsrestore' and p= aste the
output for me?

Can you also please run a full test again on a kernel built from the
current xfs-fixes-for-3.18-rc3 branch, with full dump/restore debug
enabled and send me the output? i.e.

$ xfsdump -v debug ...

and

$ xfsrestore -v debug,tree=3Dnitty ...

They ar going to produce a lot of output, so please capture it to
files rather than trying to cut/paste output to an email.

Cheers,

Dave.

Now that I think about it again, the free space is going to be related to the size of the trees so it's probably not an issue (e.g., more records in the tree, the more free space in the fs). More specifically, I see that we build up a reserve of blocks for each tree in advance in calculate_freespace_cursor() based on the number of records. That pretty much handles the general issue of the size of the metadata changing due to repair as we'll fail if there isn't enough space. All that said (and as discussed on irc), this isn't quite how I would expect to address this problem. The general algorithm for allocbt reconstruction is to calculate the blocks required for the tree based on the number of records, reserve that many blocks out of the in-core block allocation metadata, reconstruct the tree in its entirety into the buffers associated with those blocks and finally write out the buffers to disk. After the tree has been constructed, remaining extra blocks are spilled over into the agfl. Extra blocks (over reservation) seems to only occur when it is expected that the blocks allocated for the btree change the geometry of the tree from what is expected without considering said btree blocks. I would think that if we're going to potentially do an allocation to fixup the agfl, it probably makes sense to seed the agfl similar to how the btree in general is constructed from in-core metadata. The current risk here is that we don't seem to handle overestimation well. Whatever blocks are left are fit into the agfl and remaining blocks beyond that are lost. The trees have been written by the time build_agf_agfl() is called and we do go right ahead and do allocations for the agfl, so it seems like we should be able to free those extra blocks just the same (this would need to be confirmed, as I could be missing something) and eliminate that (independent) problem entirely. So with that, there is certainly more to it than giving slack to the btree leaf blocks and thus at best this is work for another day.

So this is just getting passed up from the lower level scsi devices. On a quick look, this data appears to come from the device via the "block limits VPD." Apparently that should be accessible via something like this (0xb0 from sd_read_block_limits()): # sg_inq --page=0xb0 /dev/sdx ... but I don't have a device around that likes that command. It would be interesting to know what makes the underlying device set optimal I/O size as such, but that's just curiosity at this point. :) Brian > # multipath -ll > 3600c0ff0003630917954075401000000 dm-0 Tek,DH6554 > size=44T features='0' hwhandler='0' wp=rw > |-+- policy='round-robin 0' prio=50 status=active > | `- 9:0:0:3 sdj 8:144 active ready running > `-+- policy='round-robin 0' prio=10 status=enabled > `- 1:0:0:3 sdf 8:80 active ready running > > > # blockdev --getpbsz --getss --getiomin --getioopt /dev/dm-0 > 512 > 512 > 512 > 1048576 > > # blockdev --getpbsz --getss --getiomin --getioopt /dev/sdj > 512 > 512 > 512 > 1048576 > > # blockdev --getpbsz --getss --getiomin --getioopt /dev/sdf > 512 > 512 > 512 > 1048576 > > > > Cheers, > Stan > From stan@hardwarefreak.com Thu Oct 30 15:15:11 2014 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham version=3.3.1 X-Original-To: xfs@oss.sgi.com Delivered-To: xfs@oss.sgi.com Received: from relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (Postfix) with ESMTP id 62A3D7F3F for ; Thu, 30 Oct 2014 15:15:11 -0500 (CDT) Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by relay2.corp.sgi.com (Postfix) with ESMTP id 50929304032 for ; Thu, 30 Oct 2014 13:15:08 -0700 (PDT) X-ASG-Debug-ID: 1414700107-04cb6c2efb460400001-NocioJ Received: from greer.hardwarefreak.com (mo-65-41-216-221.sta.embarqhsd.net [65.41.216.221]) by cuda.sgi.com with ESMTP id Z92dPrUWz44GbYPm for ; Thu, 30 Oct 2014 13:15:07 -0700 (PDT) X-Barracuda-Envelope-From: stan@hardwarefreak.com X-Barracuda-Apparent-Source-IP: 65.41.216.221 X-Barracuda-User-Whitelist: xfs@oss.sgi.com Received: from [192.168.100.53] (mo-65-41-216-221.sta.embarqhsd.net [65.41.216.221]) by greer.hardwarefreak.com (Postfix) with ESMTPA id E94886C18B; Thu, 30 Oct 2014 15:15:06 -0500 (CDT) Message-ID: <54529C6D.5090705@hardwarefreak.com> Date: Thu, 30 Oct 2014 15:15:41 -0500 From: Stan Hoeppner User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Icedove/24.7.0 MIME-Version: 1.0 To: Brian Foster CC: Eric Sandeen , Eric Sandeen , xfs-oss Subject: Re: [PATCH 1/2] xfsprogs: ignore stripe geom if sunit or swidth == physical sector size References: <544FD3E1.1060000@redhat.com> <20141029183721.GA4226@bfoster.laptop> <54513635.7050703@sandeen.net> <54515E4E.8010500@hardwarefreak.com> <20141030114605.GA5914@bfoster.bfoster> <54528E44.5090406@hardwarefreak.com> <20141030195046.GA48724@bfoster.bfoster> X-ASG-Orig-Subj: Re: [PATCH 1/2] xfsprogs: ignore stripe geom if sunit or swidth == physical sector size In-Reply-To: <20141030195046.GA48724@bfoster.bfoster> Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: mo-65-41-216-221.sta.embarqhsd.net[65.41.216.221] X-Barracuda-Start-Time: 1414700107 X-Barracuda-URL: http://192.48.176.15:80/cgi-mod/mark.cgi X-Virus-Scanned: by bsmtpd at sgi.com X-Barracuda-BRTS-Status: 1 On 10/30/2014 02:50 PM, Brian Foster wrote: > On Thu, Oct 30, 2014 at 02:15:16PM -0500, Stan Hoeppner wrote: >> On 10/30/2014 06:46 AM, Brian Foster wrote: >>> On Wed, Oct 29, 2014 at 04:38:22PM -0500, Stan Hoeppner wrote: >>>> On 10/29/2014 01:47 PM, Eric Sandeen wrote: >>>>> On 10/29/14 1:37 PM, Brian Foster wrote: >>>>>> On Tue, Oct 28, 2014 at 12:35:29PM -0500, Eric Sandeen wrote: >>>>>>> Today, this geometry: >>>>>>> >>>>>>> # modprobe scsi_debug opt_blks=2048 dev_size_mb=2048 >>>>>>> # blockdev --getpbsz --getss --getiomin --getioopt /dev/sdd >>>>>>> 512 >>>>>>> 512 >>>>>>> 512 >>>>>>> 1048576 >>>>>>> >>>>>>> will result in a warning at mkfs time, like this: >>>>>>> >>>>>>> # mkfs.xfs -f -d su=64k,sw=12 -l su=64k /dev/sdd >>>>>>> mkfs.xfs: Specified data stripe width 1536 is not the same as the volume stripe width 2048 >>>>>>> >>>>>>> because our geometry discovery thinks it looks like a >>>>>>> valid striping setup which the commandline is overriding. >>>>>>> However, a stripe unit of 512 really isn't indicative of >>>>>>> a proper stripe geometry. >>>>>>> >>>>>> >>>>>> So the assumption is that the storage reports a non-physical block size >>>>>> for minimum and optimal I/O sizes for geometry detection.

Any LUN of any RAID level reports the same parms. So apparently it's hard coded in the firmware. I informed our field engineer at the vendor of this issue, and the fact it prompted a patch to XFS, but haven't received a response. An educated guess is that they want to see 1 MiB IOs entering the controller regardless of the stripe geometry of the back end LUN. Could be lots of reasons for this, valid or not. However, given it advertises a minimum optimal IO size of 512 bytes this seems counterintuitive.

Can you try this patch? Cheers, Dave. -- Dave Chinner david@fromorbit.com xfs: handle munged bulkstat cookies correctly From: Dave Chinner xfsdump munges the last inode cookie that bulkstat passes to userspace so subsequent calls can restart at the last inode that bulkstat parsed. xfsdump thinks that it needs to decrement the cookie so that it catches the last inode, and this affects the tree search initialisation code. By decrementing the lastino cookie, the restart inode number can point to non-existent inode number. In 3.16, bulkstat would simply increment the cookie until it either found the next valid inode or the end of the AG, at which point it would just continue on as though nothing had happened. This is a relatively difficult situation to contrive so is extremely hard to test for, but is likely to occur fairly frequently in the real world. The current code, however, treats a cookie that points off into the weeds as invalid and returns a error. This has the effect of causing xfsdump to think it has reached the end of the bulkstat scan, and so if it's cookie munging happens just wrong it will cause incomplete dumps to occur. These dumps still have all the file data in them, just he directory structure is broken and so restore will end up with lots and lots of files in the orphanage (i.e. lost+found). IOWs, we broke xfsdump in a nasty, subtle way that users don't notice until they restore a dump. To fix this, restore the old behaviour of incrementing the inode number derived from the cookie when we fail to find a matching inode record. cc: stable@vger.kernel.org Reported-by: Tommy Wu Signed-off-by: Dave Chinner --- fs/xfs/xfs_itable.c | 34 ++++++++++++++++++++++++++++++---- 1 file changed, 30 insertions(+), 4 deletions(-) diff --git a/fs/xfs/xfs_itable.c b/fs/xfs/xfs_itable.c index 7765ff7..dcc0c99 100644 --- a/fs/xfs/xfs_itable.c +++ b/fs/xfs/xfs_itable.c @@ -208,6 +208,15 @@ xfs_bulkstat_ichunk_ra( * if we found the chunk.

xfs: handle munged bulkstat cookies correctly

From: Dave Chinner <dchinner@redh= at.com>

xfsdump munges the last inode cookie that bulkstat passes to
userspace so subsequent calls can restart at the last inode that
bulkstat parsed. xfsdump thinks that it needs to decrement the
cookie so that it catches the last inode, and this affects the
tree search initialisation code.

By decrementing the lastino cookie, the restart inode number can
point to non-existent inode number. In 3.16, bulkstat would simply
increment the cookie until it either found the next valid inode or
the end of the AG, at which point it would just continue on as
though nothing had happened. This is a relatively difficult
situation to contrive so is extremely hard to test for, but is
likely to occur fairly frequently in the real world.

The current code, however, treats a cookie that points off into the
weeds as invalid and returns a error. This has the effect of causing
xfsdump to think it has reached the end of the bulkstat scan, and so
if it's cookie munging happens just wrong it will cause incomplete
dumps to occur. These dumps still have all the file data in them,
just he directory structure is broken and so restore will end up
with lots and lots of files in the orphanage (i.e. lost+found).

IOWs, we broke xfsdump in a nasty, subtle way that users don't
notice until they restore a dump.

To fix this, restore the old behaviour of incrementing the inode
number derived from the cookie when we fail to find a matching inode
record.

Also, I just cannot reproduce a hung dump or a broken restore,
so can you take an unobfuscated metadump of the source filesystem
(i.e. the one you are running dump on) so I can try on an exact
image of the filesystem you are having troubles on?

Cheers,

Dave.

This means we allow for a single work item at a time for all possible XFS mounts on a system. fsstress testing in loopback XFS over XFS configurations has reproduced xfslogd deadlocks due to the single threaded nature of the queue and dependencies introduced between the separate XFS instances by online discard (-o discard). Discard over a loopback device converts the discard request to a hole punch (fallocate) on the underlying file. Online discard requests are issued synchronously and from xfslogd context in XFS, hence the xfslogd workqueue is blocked in the upper fs waiting on a hole punch request to be servied in the lower fs. If the lower fs issues I/O that depends on xfslogd to complete, both filesystems end up hung indefinitely. This is reproduced reliabily by generic/013 on XFS->loop->XFS test devices with the '-o discard' mount option. Further, docker implementations appear to use this kind of configuration for container instance filesystems by default (container fs->dm-> loop->base fs) and therefore are subject to this deadlock when running on XFS. Replace the global xfslogd workqueue with a per-mount variant. This guarantees each mount access to a single worker and prevents deadlocks due to inter-fs dependencies introduced by discard. Signed-off-by: Brian Foster --- Hi all, Thoughts? An alternative was to increase max jobs on the existing workqueue, but this seems more in line with how we manage workqueues these days.
