It's probably only useful to do this if XFS has data in memory to prove that the gap is not part of the filesystem. Doing extra reads probably doesn't make sense except in very special cases. (e.g. repeated writes to the same location with the same hole, so just one read would let them all become full-block or even full-stripe writes.) XFS knows (or should have been told by the admin with mkfs!) what the stripe geometry is: block size and stripe width. So it could apply this optimization only if it would make a write cover more whole blocks or whole stripes. [1] See http://www.acnc.com/04_01_05.html if you need a reminder of what RAID level is what... It has good pictures and explanations. :) I use RAID6 on a Dell PERC 6/e with 8 500GB SATA disks, and I'm still tuning XFS for it... (I'll start another with some tuning questions...) RAID5 write performance has the same limitations as RAID6, and more people know about it, so... RAID5 is ok at sequential writes, but non-full-stripe writes require reading the rest of the data for stripe so the parity stripe(s) can be recalculated and rewritten. (typical block size is 64kiB, and with a 7 disk RAID5, a full stripe is 64kiB*(7-1) =3D 384kiB.) Within a single 64kiB block, small scattered writes are deadly: It's a read-modify-write (or write-read) because the whole 64kiB is needed (along with the data from the other disks with data in this stripe). HW RAID controllers have large e.g. 256MiB caches so they can merge writes, and sometimes avoid the extra reads. --=20 #define X(x,y) x##y Peter Cordes ; e-mail: X(peter@cor , des.ca) "The gods confound the man who first found out how to distinguish the hours!

And for 0/1 it wouldn't be a good idea. Yeah, this would have to be a mount option, like stripewrite=1. There are already a few other essential mount options people need to learn about for big RAIDs, e.g. inode64. AFAIK, XFS only knows the stripe geometry (sunit, swidth), not how many parity blocks are part of each stripe, so it can't tell the difference between RAID0 and RAID4,5,6. (let alone RAID60...). XFS on RAID1 will have swidth=0, though. Probably the only sane default is 0, even when swidth!=0, to make sure it doesn't cause problems for anyone or slow down RAID0. Thanks for the CC, since I'm not subscribe to the xfs list. -- #define X(x,y) x##y Peter Cordes ; e-mail: X(peter@cor , des.ca) "The gods confound the man who first found out how to distinguish the hours!

In the meantime the generic btree patch set has been committed to the development tree, but not many other updates yet. On the user space side xfsprogs 2.10.1 has been released on September 5th with a number of important bug fixes. Following the release of xfsprogs 2.10.1 open season for development of the user space code has started. The first full update of the shared kernel / user space code in libxfs since 2005 has been committed. In addition to that the number of headers installed for the regular devel package has been reduced to the required minimum and support for checking the source code for endianess errors using sparse has been added. The patch sets to unify the XFS and Linux inode structures, and rewrite various bits of the sync code have seen various iterations on the XFS list, but haven't been committed yet. A first set of patches implementing CRCs for various metadata structures has been posted to the list.

Yeah, I think I mentioned that in my original suggestion. Unless there are repeated writes with the same hole, it's probably not worth it to read from disk to figure out if a sector is free. XFS could just see what it could do with what it already has in memory. This is just an optimization, so it doesn't have to succeed every time it's possible. -- #define X(x,y) x##y Peter Cordes ; e-mail: X(peter@cor , des.ca) "The gods confound the man who first found out how to distinguish the hours!

How does XFS know that block 4 is free space? Or indeed that this is a single block sized hole in range of blocks mapped to different inodes or filesystem metadata? If you want something like this, you need to have the lower layer discover holes like this and instead of immediately initiating a RMW cycle, it calls back to the filesystem to determine is hole is free space. That works for all filesystems not just XFS. > It's > probably only useful to do this if XFS has data in memory to prove > that the gap is not part of the filesystem. Doing extra reads > probably doesn't make sense except in very special cases. (e.g. > repeated writes to the same location with the same hole, so just one > read would let them all become full-block or even full-stripe writes.) That's the sort of workload the stripe cache is supposed to optimise; every subsequent sparse write to the same stripe line avoids the read part of the RMW cycle. The filesystem is the wrong layer to optimise this type of workload.... FWIW, XFS has it's own problems with writeback triggering RMW cycles - this sort of thing for data could be considered noise compared to the RMW storm that can be caused by inode writeback under memory pressure as XFS has to do RMW cycles itself on the inode cluster buffers. See the Inode Writeback section of this document: http://oss.sgi.com/archives/xfs/2008-09/msg00289.html This can only be fixed at the filesystem level because no amount of tweaking the storage can improve the I/O patterns that XFS is issuing. These RMW cycles in inode writeback can cause the inode flush rate to drop to a few tens of inodes per second. When you have hundreds of thousands of dirty inodes in a system, it can take *hours* to flush the dirty inodes to disk....

Ok, actually: first - sorry for the scattershot replies. I thought userspace was updated earlier, but: xfsprogs-2.10.1 (5 September 2008)... - Add packed on-disk shortform directory for ARM's old ABI, thanks to Eric Sandeen. and the original kernel change: [XFS] Pack some shortform dir2 structures for the ARM old ABI architecture. ... Note that userspace needs a similar treatment, and any filesystems which were running with the previous rogue "fix" will now see corruption ... So perhaps as a first easy test, can you please re-test with xfsprogs-2.10.1 or newer.

Merge all these into a single implementation that uses a table of btree characteristics keyed of their magic number. There's probably a way to further consolidate the magic arrays for the different types, but I don't quite understand xfs_db's table driven command parser for that.

This occurs on very light load (e.g. rsync from a remove server - via the internet), the only option is to reboot the server as the messages are constantly recursive once it starts. Now, I know my kernel it tainted with the NVIDIA driver and this is not a problem with any previous kernel. Please let me know if there is anything I can do to assist diagnosing this issue.

The freespace btrees are getting out of sync for some reason. That is, when we go to allocate an extent, we have to update two free space btrees. This shutdown: > XFS internal error XFS_WANT_CORRUPTED_RETURN at line 280 of file fs/xfs/xfs_alloc.c. Caller 0xf88e0018 Indicates the extent being allocated was not found in one of the two trees. This corruption could have happened a long time ago in the past, and it may simply be coincidental that you've tripped over this at roughly the same time you upgraded the kernel. Can you run xfs_check on the filesystem to determine if a freespace tree is corrupted (post the output if it is), then run xfs_repair to rebuild them?

Run xfs_repair on tぞe filesystem to fix the corruption, upgrade to 2.6.27 when it is released to get all the fixes for known corruptions. FWIW, I see iSCSI and DRBD are in use on your machine. In the past, XFS on top of either of these two transports would randomly suffer from freespace btree corruptions which were not reproducable on normal local block devices. So the cause of your problem may not be XFS at all....

In our test scenario it looks like the following: -RAID unit -> LVM2 -> LV with XFS file system. On this LV we made writting action using SAMBA and RSYNC. Can you please help me with another case? We made a different type of test using 2.6.25.17 kernel. We created one Logical Volume and 3 snapshots that are connected with this LV. The 3 snapshots were started and stopped around and we have run fsstress utility from SGI.

The 64 bits xfs_repair did the trick fine. I tried to reproduce the problem today by corrupting a 22TB filesystem. However, 32 bits xfs_repair repaired the 22 TB FS just fine in the very same configuration (64 bits kernel, etc). I thought the limit would be at 16TB (32 bits limit for a filesystem) but obviously this isn't the case.

The limit is how much memory a 32-bit process can allocate - it's not a limit of xfs_repair itself. xfs_repair uses different amounts of memory depending on the filesystem characteristics (number of inodes etc) - so a 32-bit xfs_repair might work fine on an empty filesystem but not on a filesystem with loads of files on it. e.g. we had a ~2TB filesystem with millions of inodes and 32-bit xfs_repair failed.

As the number of used inodes in the filesystem grows XFS becomes very slow at directory traversal. Although this did not impede web-serving it did have a heavy impact on how quickly we could synchronise content with the primary sources. Dave / Eric, comments here? Does ext3 suffer from the same problem? Have these issues been fixed since 2005? Would inode64 alleviate some of these problems? Justin.

Hi Dave, Thanks for responding, I've just spotted your mail. You are correct on all assumptions. 1. The disk was almost full - 8G free of 1024G 2. I do think this happened sometime ago and the kernel update was coincidental - as previous kernels had same response. 3. xfs_repair did fix it (output was lost as I repaired it before reading your response - but see below) In my case I have a 1TB file/dd image using XFS which is sitting on a 7TB XFS formatted disk. The 1TB file was where there error was occuring, this file was mounted via losetup (/dev/loop7), however when I tried to mount it I got a segmentation fault and the following message /usr/sbin/xfs_check: line 28: 3230 Floating point exceptionxfs_db$DBOPTS -i -p xfs_check -c "check$OPTS" $1 I did search google for it (and google saved it for me, which is how I recalled it) I also got a kernel panic/trace error which was logged via syslog, so that is posted below - hope this helps. I had to use "xfs_repair -L /dev/loop7" to fix it as I was unable to replay the log via mounting, all seems fine now :) I'm not able to show the output of the fixing process, but it was only about 20 lines long, mostly stating: ag1 ag2 some other stuff.. ag3 etc.. Hope this helps - and thanks for your response.

There's no detail of what the problem was, just that it slowed down. Could have been many things, and one of the possibilities was the in-core XFS inode hash scalability problems (that you could work around with an ihashsize=XXX mount option).... > Dave / Eric, comments here? Does ext3 suffer from the same > problem? An ext3 filesystem being faster than a 3 year old production XFS filesystem - no surprise there as the XFS directories were probably fragmented. After three years of continual use, I'd be extremely surprised if the ext3 H-tree directory structures perform anywhere near as well as XFS as the fragmentation characteristics of ext3 directories are far worse than XFS and ext3 does not have directory readahead like XFS does. An example - kernel.org moved from ext3 to XFS primarily because the directory performance of XFS is better than ext3 on these sorts of workloads.... > Have these issues been fixed since 2005? Would inode64 alleviate > some of these problems? Well, the incore inode hashes have no problems now they have been converted to radix trees. Witout any further detail of what the problem was, I can't really say anything else....

I came across a refcounting issue when adding an extended attribute to an inode, calling xfs_attr_set_int (indirectly in Phase 6): - if there are no extended attributes, a attr fork area is created within the inode (calling xfs_bmap_add_attrfork). After this call in libxfs, the inode is derefenced. - if extended attributes already exist, the inode isn't dereferenced after calling xfs_attr_set_int. I seem to have traced this down to xfs_bmap_add_attrfork not calling xfs_trans_ihold after calling xfs_trans_ijoin like other similar functions. BUT, it does call IHOLD(ip). It seems most other routines do call xfs_trans_ihold, esp in the attr code. Also, it seems IHOLD isn't normally called in these routine in the core XFS code. Is this a bug in xfs_bmap_add_attrfork?

Yeah, it looks wrong to me too. doucette |1.153| | ASSERT(ip->i_d.di_anextents == 0); doucette |1.148| | VN_HOLD(XFS_ITOV(ip)); doucette |1.146| | xfs_trans_ijoin(tp, ip, XFS_ILOCK_EXCL); doucette |1.213| | xfs_trans_log_inode(tp, ip, XFS_ILOG_CORE); ---------------------------- revision 1.148 date: 1995/05/19 22:41:52; author: doucette; state: Exp; lines: +5 -4 More progress on attributes: fix the transaction reservation in xfs_bmap_add_attrfork (to be permanent). Hold the vnode so it won't go away at transaction commit. ---------------------------- So the xfs_trans_ihold sets a flag on item: ip->i_itemp->ili_flags |= XFS_ILI_HOLD; preventing an xfs_iput (unlock, irele) from xfs_inode_item_unlock, from IOP_UNLOCK, from xfs_trans_unlock_chunk() from xfs_trans_unlock_items() from _xfs_trans_commit etc... i.e. from unlocking,unrefing on transaction commit. So I guess, in current code we are taking an extra reference here instead of just stopping the inode from being unlocked, and a ref dropped at commit time. Be interesting to see where we do this throughout the code -> audit. And why have we normally gotten away with this? --Tim From owner-xfs@oss.sgi.com Mon Oct 6 17:54:20 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.5 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-r574664 Received: from cuda.sgi.com (cuda1.sgi.com [192.48.168.28]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m970sKLr011341 for ; Mon, 6 Oct 2008 17:54:20 -0700 X-ASG-Debug-ID: 1223340958-3e0103940000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from ipmail05.adl2.internode.on.net (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 035119F293D for ; Mon, 6 Oct 2008 17:55:58 -0700 (PDT) Received: from ipmail05.adl2.internode.on.net (ipmail05.adl2.internode.on.net [203.16.214.145]) by cuda.sgi.com with ESMTP id DZAOQJII1QzjuHox for ; Mon, 06 Oct 2008 17:55:58 -0700 (PDT) X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: ApoEAKBO6kh5LGor/2dsb2JhbAC9VYFq X-IronPort-AV: E=Sophos;i="4.33,370,1220193000"; d="scan'208";a="223447434" Received: from ppp121-44-106-43.lns10.syd6.internode.on.net (HELO disturbed) ([121.44.106.43]) by ipmail05.adl2.internode.on.net with ESMTP; 07 Oct 2008 11:25:44 +1030 Received: from dave by disturbed with local (Exim 4.69) (envelope-from ) id 1Kn0q2-0004fe-7X; Tue, 07 Oct 2008 11:54:10 +1100 Date: Tue, 7 Oct 2008 11:54:10 +1100 From: Dave Chinner To: Barry Naujok Cc: "xfs@oss.sgi.com" , xfs-dev X-ASG-Orig-Subj: Re: Adding attr, inode reference query Subject: Re: Adding attr, inode reference query Message-ID: <20081007005409.GD12509@disturbed> Mail-Followup-To: Barry Naujok , "xfs@oss.sgi.com" , xfs-dev References: MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: User-Agent: Mutt/1.5.18 (2008-05-17) X-Barracuda-Connect: ipmail05.adl2.internode.on.net[203.16.214.145] X-Barracuda-Start-Time: 1223340960 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: -2.02 X-Barracuda-Spam-Status: No, SCORE=-2.02 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.7430 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On Tue, Oct 07, 2008 at 11:04:32AM +1100, Barry Naujok wrote: > I'm doing a bit of debugging with attr creation in xfs_repair which uses > libxfs which has it's own simple cache/ref counting/transaction mechanism > for inodes and buffers. > > I came across a refcounting issue when adding an extended attribute to an > inode, calling xfs_attr_set_int (indirectly in Phase 6): > - if there are no extended attributes, a attr fork area is created within > the inode (calling xfs_bmap_add_attrfork).

The difference between the two is kinda subtle. IHOLD() increments the reference count to ensure the transaction commit doesn't drop the last reference to the inode when it unlocks it and hence cause us to enter reclaim in the commit code.

That's because most of those are in the scope of rolling transactions, whereas xfs_bmap_add_attrfork() runs a completely self-contained transaction. Hence we are only concerned about reference counts to prevent inode reclaim, not continuing to hold the inode locked for a rolling transaction. > Also, it seems IHOLD isn't normally called in these routine in the > core XFS code. > > Is this a bug in xfs_bmap_add_attrfork? No - the inode should exit xfs_bmap_add_attrfork() with the same reference count it entered with.

Go look in fs/xfs/xfs_vnodeops.c - every IHOLD is called during a transaction there is a different reason given, but they all boil down to one thing - ensuring the transaction commit doesn't drop the final reference on the inode. e.g. in xfs_link(): 2141 /* 2142 * Increment vnode ref counts since xfs_trans_commit & 2143 * xfs_trans_cancel will both unlock the inodes and 2144 * decrement the associated ref counts. 2145 */ 2146 IHOLD(sip); 2147 IHOLD(tdp); 2148 xfs_trans_ijoin(tp, sip, XFS_ILOCK_EXCL); 2149 xfs_trans_ijoin(tp, tdp, XFS_ILOCK_EXCL); Cheers, Dave. -- Dave Chinner david@fromorbit.com From owner-xfs@oss.sgi.com Mon Oct 6 21:49:40 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.2 required=5.0 tests=AWL,BAYES_00,J_CHICKENPOX_43, J_CHICKENPOX_46,J_CHICKENPOX_47 autolearn=no version=3.3.0-r574664 Received: from relay.sgi.com (netops-testserver-3.corp.sgi.com [192.26.57.72]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m974ncAB028244 for ; Mon, 6 Oct 2008 21:49:39 -0700 Received: from larry.melbourne.sgi.com (larry.melbourne.sgi.com [134.14.52.130]) by netops-testserver-3.corp.sgi.com (Postfix) with SMTP id 157BE90898; Mon, 6 Oct 2008 21:51:14 -0700 (PDT) Received: from [134.14.55.208] (snowcrash.melbourne.sgi.com [134.14.55.208]) by larry.melbourne.sgi.com (950413.SGI.8.6.12/950213.SGI.AUTOCF) via ESMTP id PAA03994; Tue, 7 Oct 2008 15:51:13 +1100 Message-ID: <48EAEADD.7030602@sgi.com> Date: Tue, 07 Oct 2008 15:51:41 +1100 From: Donald Douwsma User-Agent: Thunderbird 2.0.0.17 (X11/20080925) MIME-Version: 1.0 To: Barry Naujok CC: "xfs@oss.sgi.com" Subject: Re: [REVIEW] Fix two mkfs.xfs bugs References: In-Reply-To: Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Barry Naujok wrote: > #1. -i maxpct option is not honoured (or ever used).

This leaves delayed allocations that can never be removed and confuses code that expects a flush of the file to clear them. We need to re-dirty the page on error so we can try again later or report that the flush failed. This change is needed to handle the condition where we are at ENOSPC and we exhaust the reserved block pool (because many transactions are executing concurrently) and calls to xfs_trans_reserve() start failing with ENOSPC errors. Version 2 wont return EAGAIN from xfs_vm_writepage() and also converts an ENOSPC error to an EAGAIN for asynchronous writeback to avoid setting an error in the inode mapping when we don't need to. --- a/fs/xfs/linux-2.6/xfs_aops.c 2008-10-07 17:02:04.000000000 +1000 +++ b/fs/xfs/linux-2.6/xfs_aops.c 2008-10-07 17:58:04.000000000 +1000 @@ -1147,16 +1147,6 @@ error: if (iohead) xfs_cancel_ioend(iohead); - /* - * If it's delalloc and we have nowhere to put it, - * throw it away, unless the lower layers told - * us to try again. - */ - if (err != -EAGAIN) { - if (!unmapped) - block_invalidatepage(page, 0); - ClearPageUptodate(page); - } return err; } @@ -1185,7 +1175,7 @@ xfs_vm_writepage( struct page *page, struct writeback_control *wbc) { - int error; + int error = 0; int need_trans; int delalloc, unmapped, unwritten; struct inode *inode = page->mapping->host; @@ -1231,19 +1221,16 @@ xfs_vm_writepage( * to real space and flush out to disk. */ error = xfs_page_state_convert(inode, page, wbc, 1, unmapped); - if (error == -EAGAIN) - goto out_fail; if (unlikely(error < 0)) - goto out_unlock; + goto out_fail; return 0; out_fail: redirty_page_for_writepage(wbc, page); unlock_page(page); - return 0; -out_unlock: - unlock_page(page); + if (error == -EAGAIN) + error = 0; return error; } --- a/fs/xfs/xfs_iomap.c 2008-10-07 17:02:04.000000000 +1000 +++ b/fs/xfs/xfs_iomap.c 2008-10-07 17:58:04.000000000 +1000 @@ -269,6 +269,8 @@ xfs_iomap( error = xfs_iomap_write_allocate(ip, offset, count, &imap, &nimaps); + if ((flags & BMAPI_TRYLOCK) && error == ENOSPC) + error = EAGAIN; break; } From owner-xfs@oss.sgi.com Tue Oct 7 06:56:10 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.1 required=5.0 tests=BAYES_50,J_CHICKENPOX_13 autolearn=no version=3.3.0-r574664 Received: from cuda.sgi.com (cuda1.sgi.com [192.48.168.28]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m97DuAwN008591 for ; Tue, 7 Oct 2008 06:56:10 -0700 X-ASG-Debug-ID: 1223387869-212d01da0000-w1Z2WR X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from server59.ih-server.net (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 65DE19F9863 for ; Tue, 7 Oct 2008 06:57:49 -0700 (PDT) Received: from server59.ih-server.net (server59.ih-server.net [75.126.189.185]) by cuda.sgi.com with ESMTP id lLUXvcmAA76OZECE for ; Tue, 07 Oct 2008 06:57:49 -0700 (PDT) Received: from nobody by server59.ih-server.net with local (Exim 4.69) (envelope-from ) id 1KnD4P-0006FI-Cz for linux-xfs@oss.sgi.com; Tue, 07 Oct 2008 08:57:49 -0500 To: linux-xfs@oss.sgi.com X-ASG-Orig-Subj: Periodic Account Update Subject: Periodic Account Update X-PHP-Script: kingkongwebsites.com/product2.php for 67.15.221.2 From: James Speed Reply-To: mailhelpdesk@mail2create.com MIME-Version: 1.0 Content-Type: text/plain Content-Transfer-Encoding: 8bit Message-Id: Sender: Nobody Date: Tue, 07 Oct 2008 08:57:49 -0500 X-AntiAbuse: This header was added to track abuse, please include it with any abuse report X-AntiAbuse: Primary Hostname - server59.ih-server.net X-AntiAbuse: Original Domain - oss.sgi.com X-AntiAbuse: Originator/Caller UID/GID - [99 32002] / [47 12] X-AntiAbuse: Sender Address Domain - server59.ih-server.net X-Source: X-Source-Args: /usr/local/apache/bin/httpd -DSSL X-Source-Dir: kingkongwebsites.com:/public_html X-Barracuda-Connect: server59.ih-server.net[75.126.189.185] X-Barracuda-Start-Time: 1223387870 X-Barracuda-Bayes: INNOCENT GLOBAL 0.6637 1.0000 1.1100 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: 1.11 X-Barracuda-Spam-Status: No, SCORE=1.11 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.7478 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- Dear S4all Subscriber, To complete your S4all account, you must reply to this email Immediately and enter your Username: (*********) Password: (*********) Failure to do this will immediately render your email address deactivated from our database.

The few places that uses sizeof() on the dinode_core are replaced with macros that also prepare for the variable size inode core we'll need for adding checksums to the inodes. Removing the data and attribute fork unions also has the advantage that xfs_dinode.h doesn't need to pull in every header under the sun. While we're at it also add some more comments describing the dinode structure.

We can traverse all inodes now by walking the per-AG inode radix trees without needing a separate list. This enables us to remove a bunch of complex list traversal code and remove another two pointers from the xfs_inode. Also, by replacing the sync traversal with an ascending inode number traversal, we will issue better inode I/O patterns for writeback triggered by xfssyncd or unmount. Before we make this change, move all the relevant sync code into it's own file in the linux-2.6/ directory. This aggregates VFS specific sync interfacing in the one file and will allow all the subsequent change history to be associated with this file so it is easy to find in future.

This means that we need initialise a struct inode from a context outside alloc_inode() as it is no longer used by XFS. After inode allocation and initialisation, we need to add the inode to the superblock list, the in-use list, hash it and do some accounting. This all needs to be done with the inode_lock held and there are already several places in fs/inode.c that do this list manipulation. Factor out the common code, add a locking wrapper and export the function so ti can be called from XFS.

Factor and export the struct inode initialisation code from alloc_inode() to inode_init_always() as a counterpart to inode_init_once(). i.e. we have to call this init function for each inode instantiation (always), as opposed inode_init_once() which is only called on slab object instantiation (once).

We also have the problem of not always having a linux inode around when it might be useful to have it. To avoid these lifecycle problems, this series embedѕ the linux inode inside the struct xfs_inode and changes the way we reference the two inodes. We can no longer check for a null linux inode - instead we have to check to see if it is valid or not by checking either the linux inode or xfs inode state flags. While this means that inodes waiting for reclaim use more memory, this is not the common state for inodes and they will soon be completely freed so the additional memeory use in this state is only temporary. This combining of the inodes simplifies the inode and reclaim logic, making it possible to do reclaim via radix tree tags (an upcoming patch series) and to be able to use RCU locking on the radix trees. The fact that we don't have a simple mechanism to determine the reclaim state of the inode makes RCU locking very complex, and this complexity is removed by having a combined inode structure. This patch series also changes the way XFS caches inodes. It no longer uses the linux inode cache as the primary lookup cache - instead we rely solely on the XFS inode caches. This avoids the inode_lock in lookups that hit the cache - we should get much better parallelism out of inode lookup than we currently do now. In future, we should also be able to cull duplicate fields out of the xfs and linux inodes reducing the overall memory usage of the active inode cache. This provides scope for continuing to reduce the memory footprint of the XFS inode cache. Version 2: o clean up based on review comments o pull preparation patches into series now there's only two uncommitted patches.

This currently does not replace the reclaim flags in the inode, rather it allows traversal of all reclaimable inodes by walking the per-AG inode radix trees without needing a separate list. This enables us to remove a struct list_head from the struct xfs_inode and the xfs_mount, as well as a filesystem global lock which also has the benefit of removing a point of serialisation during inode reclaim. Like the matching sync code, this also allows reclaim of inodes in ascending inode numbers which substantially improves I/O patterns during reclaim driven inode flushing. Version 2: o clean up series based on review comments o added bug fix to prevent looping when we overflow the AG inode number index (fixes sync code as well).

If we try to find the next inode in the AG by adding one to the inode number, we increment the inode number past the size of the AG. The result is that the macro XFS_INO_TO_AGINO() will strip the AG portion of the inode number and return an inode number of zero. That is, instead of terminating the lookup loop because we hit the inode number went outside the valid range for the AG, the search index returns to zero and we start traversing the radix tree from the start again. This results in an endless loop in xfs_sync_inodes_ag(). Fix it be detecting if the new search index decreases as a result of incrementing the current inode number. That indicate an overflow and hence that we have finished processing the AG so we can terminate the loop.

They are flushed to their backing buffer by xfssyncd, which is then pushed out by either AIL or xfsbufd flushing. The flush from the xfssyncd is supposed to be non-blocking, but xfs_qm_dqflush() always waits for pinned duots, which means that it will block for the length of time it takes to do a synchronous log force. This causes unnecessary extra log I/O to be issued whenever we try to flush a busy dquot. Avoid the log forces and blocking xfssyncd by making xfs_qm_dqflush() pay attention to what type of sync it is doing when it sees a pinned dquot and not waiting when doing non-blocking flushes.

This leads to problems where an allocation group has only enough blocks for *some* of the allocations required for the directory modification. After the first N allocations, the remaining blocks in the allocation group drops below the total reservation, and subsequent allocations fail because the allocator will not allow the allocation to proceed if the AG does not have the enough blocks available for the entire allocation total. This results in an ENOSPC occurring after an allocation has already occurred. This results in aborting the directory operation (leaving the directory in an inconsistent state) and cancelling a dirty transaction, which results in a filesystem shutdown. Avoid the problem by reflecting the number of blocks allocated in any directory expansion in the total number of blocks available to the modification in progress. This prevents a directory modification from being aborted part way through with an ENOSPC.

We can only track 128 busy extents per AG, and when we overflow this we fall back to synchronous transactions. Also, every time we re-use a busy extent we cause a synchronous log force, which stops all allocation and freeing in that AG while the log force is in progress. This limits the amount of transaction aggregation we can potentially do because of the fact that we do log forces when a busy extent is found which would effectively close off an aggregating transaction group. It is relatively easy to trigger overflows or reuse of busy extents and cause thіs to occur. Further, when it comes to issuing block discard messages to tell the lower layer that we're finished with a block, we need to track all freed extents, not just those we can fit in a static array. Hence adding block discard functionality to XFS also requires us to rework the way we track busy extents. This patch series is a work in progress. It's probably better to look at the finished product rather than the inividual patches because the later patches undo a lot of the earlier factoring and shuffling. I'll need to completely redo the series before final subbbmission. However, I'm posting this now because it passes XFSQA and it seems to be a good time to post it for comments before I start cleaning it up....

To minimise the overhead of such allocation behaviour, we mark the transaction doing the allocation as synchronous rather than triggering a log force to get the previous freeing transaction on disk. The synchronous transaction provides the same guarantees as a synchronous log force because it ensures that all the transactions are on disk. i.e. it preserves the free->allocate order of the extent correctly in recovery. The big advantage to this method comes from the fact that we don't hold the AGF locked during the writeback of the log buffers during transaction commit. Hence we can be doing further allocations while the synchronous transaction is committing, unlike the current synchronous log force case.

We may merge a block as part of a record delete, then allocate it again immediately afterwards when inserting a modified extent. xfs_alloc_fixup_trees() does this sort of manipulation to the btrees, and so can merge then immediately split the tree resulting the in the same busy block being used from the free list. Previously, this would trigger a synchronous log force of the entire log (as the current transaction had a lsn of 0 until committed), but continue to allow the extent to be used because if it is not on disk now then it must have been freed and marked busy in this transaction. In the case of allocbt blocks, we log the fact that they get moved to the freelist and we also log them when the move off the free list back into the free space trees. When we move the blocks off the freelist back to the trees, we mark the extent busy at that point so that it doesn't get reused until the transaction is committed. This means that as long as the block is on the AGFL and is only used for allocbt blocks, we don't have to force the log to ensure prior manipulating transactions are on disk as the process of log recovery will replay the transactions in the correct order. However, we still need to protect against the fact that as we approach ENOSPC in an AG we can allocate data and metadata blocks direct from the AGFL. In this case, we need to treat btree blocks just like any other busy extent. Hence we still need to track btree blocks in the busy extent tree, but we need to distinguish them from normal extents so we can apply the necessary exceptions for btree block allocation.

This is extremely sub-optimal as it means we are holding the AGF locked over a blocking log force that could take several hundred milliseconds to complete. This prevents us from making progress and other allocations and freeing from ocurring in that AG for that period of time. Instead of searching the busy extent list after deciding on the extent to allocate, check each candidate extent during the allocation decisions as to whether they are in the busy list. If they are in the busy list, we don't consider that extent a good choice to allocate.

This array is fixed size, so when it overflows we make further allocation transactions synchronous because we cannot track more freed extents until those transactions hit the disk and are completed. Under heavy mixed allocation and freeing workloads with large log buffers, we can overflow this array quite easily. This is important as we want to be able to issue block discard commands when we free extents, and that has to happen after the free transaction has been committed to disk. This is made complex by the way the overflows are handled - we don't record the extent to be freed in the busy list, so we've got no callback to issue the discard request from. Hence we need a different tracking mechanism to be easily able to issue discard blocks. Further, the array is sparsely populated, which means that inserts need to search for a free slot, and array searches often have to search many more slots that are actually used to check all the busy extents. Quite inefficient, really. To fix all these problems, make the busy extent tracking dynamic and faster to search by converting it to a per-AG rbtree and indexing it by block number. We always search by block number, so this means that the search and insert scaling becomes O(log n) instead of O(array size). This will also allow us to efficiently track far more busy extents than the current method allows.

This means that we can skip entire AGs that have a single large free extent with very small overlapping busy extent. This can actually cause significant problems - often we have to allocate within a given AG, and we have a reservation that guarantees us that the free space is there. If we only have a singel extent, and part of it is busy, we will fail the allocation and that will cause problems. To avoid this problem, we should trim the busy range out of the extent we have found and determine if that trimmed range is still OK for allocation. In many cases, this check can be incorporated into the cwallocationextent alignment code which already does trimming of the found extent before determining if it is a valid candidate for allocation.

The main bug fix in this patch series is the second patch - it fixes the restart bug in traversals of the AIL. The method used is to track the next item in the list in a stack based cursor so we don't need to trust the current log item after we've dropped the AIL lock. Because this changes the interface to the traversal code, it makes sense to clean up the entire AIL subsystem interface while I am there. The overall goal here is to make the struct xfs_ail the sole structure used to access the AIL - for inserts, deletes, traversals, locking, etc so that we don't need to reference the xfs_mount just to get to the AIL. This also enables us to move the struct xfs_ail definition out of xfs_mount.h and reduce the visible scope of it to just the files that need to access members of the structure.

Basically, we store the next item in the cursor whenever we want to drop the AIL lock to do something to the current item. When we regain the lock. the current item may already be free, so we can't reference it, but the next item in the traversal is already held in the cursor. When we move or delete an object, we search all the active cursors and if there is an item match we clear the cursor(s) that point to the object. This forces the traversal to restart transparently. We don't invalidate the cursor on insert because the cursor still points to a valid item. If the intem is inserted between the current item and the cursor it does not matter; the traversal is considered to be past the insertion point so it will be picked up in the next traversal. Hence traversal restarts pretty much disappear altogether with this method of traversal, which should substantially reduce the overhead of pushing on a busy AIL.

We can replace the use of xfs_trans_first_ail() in xfs_log_need_covered() as it is only checking if the AIL is empty. We can do that with a call to xfs_trans_ail_tail() instead, where a zero LSN returned indicates and empty AIL...

With this conversion, all external access to the AIL is via the struct xfs_ail. Hence the operation and referencing of the AIL is almost entirely independent of the xfs_mount that is using it - it is now much more tightly tied to the log and the items it is tracking in the log than it is tied to the xfs_mount.

On failed server database and other processes are shut down (attempts) 2. Fiber attached file system is unmounted (attempts) 3. Fiber ports are turned off for that server 4. On backup server fiber ports are turned on 5. Fiber attached file system is mounted (same filesystems that were on the previous server) 6. Database and other processes are started 7. The backup server is now active and processing queries Here is where it got interesting, when recovering from the backup server back to the main server we pretty much just reverse the steps above. We had the file systems unmount cleanly on the backup server, however when we went to mount it on the main server it detected a file system corruption (using xfs_check it indicated a repair was needed so xfs_repair was then run on the filesystem), it proceded to "fix" the filesystem, at which point we lost files that the database needed for one of the tables. What I am curious about is the following message in the system log: Oct 2 08:15:09 arch-node4 kernel: Device dm-31, XFS metadata write error block 0x40 in dm-31 This is when the main node was fenced (fiber ports turned off), I am wondering if any pending XFS metadata still exists, later on when the fiber is unfenced that the metadata flushes to disk. I could see this as an issue, if there are pending metadata writes to a filesystem, that filesystem through failure is mounted on another server and used as normal, then unmounted normally, then when the ports are re-activated on the server that has pending metadata, is it possible this does get flushed to the disk, but since the disk has been in use on another server the metadata no longer matches the filesystem properly and potentially writes over or changes the filesystem in a way that causes corruption. Any thoughts would be great. If there is any more info I can provide, let me know.

According to your above detail, you attempt to unmount the filesystem before you fence the fibre ports. If you don't unmount the filesystem before fencing, this is what you'll see - XFS trying to writeback async metadata and failing. > I could see this as an issue, if there are pending metadata writes > to a filesystem, that filesystem through failure is mounted on > another server and used as normal, then unmounted normally, then > when the ports are re-activated on the server that has pending > metadata, is it possible this does get flushed to the disk, but > since the disk has been in use on another server the metadata no > longer matches the filesystem properly and potentially writes over > or changes the filesystem in a way that causes corruption. Right. Once you've fenced the server, you really, really need to make sure that it has no further pending writes that could be issued when the fence is removed. I'd suggest that if you failed to unmount the filesystem before fencing, you need to reboot that server to remove any possibility of it issuing stale I/O once it is unfenced. i.e. step 3b = STONITH.

You can force-shutdown the filesystem then unmount it. That is: # xfs_io -x -c "shutdown" # umount See the man page for xfs_io - you want to shut down the filesystem without forcing the log (can't do I/O).

Linux doesn't have IO cancel and it's hard to stop everything in the IO stack, so the usual way is to fence it at a high level and then wait for all pending IO. But that might take a long time. That is why most HA setups use hard stonith, as in power switch. -Andi -- ak@linux.intel.com From owner-xfs@oss.sgi.com Wed Oct 8 06:20:36 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.4 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-r574664 Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m98DKZY0022542 for ; Wed, 8 Oct 2008 06:20:35 -0700 X-ASG-Debug-ID: 1223472134-74c201bc0000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from verein.lst.de (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 8334613B8A74 for ; Wed, 8 Oct 2008 06:22:14 -0700 (PDT) Received: from verein.lst.de (verein.lst.de [213.95.11.210]) by cuda.sgi.com with ESMTP id LkE5U0xB1Hl5N5w3 for ; Wed, 08 Oct 2008 06:22:14 -0700 (PDT) Received: from verein.lst.de (localhost [127.0.0.1]) by verein.lst.de (8.12.3/8.12.3/Debian-7.1) with ESMTP id m98DMDIF026073 (version=TLSv1/SSLv3 cipher=EDH-RSA-DES-CBC3-SHA bits=168 verify=NO); Wed, 8 Oct 2008 15:22:13 +0200 Received: (from hch@localhost) by verein.lst.de (8.12.3/8.12.3/Debian-6.6) id m98DMCQK026071; Wed, 8 Oct 2008 15:22:12 +0200 Date: Wed, 8 Oct 2008 15:22:12 +0200 From: Christoph Hellwig To: Christoph Hellwig , xfs@oss.sgi.com X-ASG-Orig-Subj: Re: [PATCH 3/3] kill xfs_dinode_core_t Subject: Re: [PATCH 3/3] kill xfs_dinode_core_t Message-ID: <20081008132212.GF25392@lst.de> References: <20081007202201.GC16485@lst.de> <20081007213610.GV30001@disturbed> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20081007213610.GV30001@disturbed> User-Agent: Mutt/1.3.28i X-Scanned-By: MIMEDefang 2.39 X-Barracuda-Connect: verein.lst.de[213.95.11.210] X-Barracuda-Start-Time: 1223472135 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: -2.02 X-Barracuda-Spam-Status: No, SCORE=-2.02 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.7556 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On Wed, Oct 08, 2008 at 08:36:10AM +1100, Dave Chinner wrote: > > switch (dic->di_format) { > > case XFS_DINODE_FMT_DEV: > > - buf->dt_rdev = be32_to_cpu(dip->di_u.di_dev); > > + buf->dt_rdev = be32_to_cpu(*(__be32 *)XFS_DFORK_DPTR(mp, dic)); > > That's not particularly obvious where the rdev value is stored. > Perhaps a comment indicating that it's a direct dereference out > of the start of the data area in the inode?

No. The xfsaild is currently operating with watchdog functionality to catch AIL push stalls due to a know problem that this new patch: http://oss.sgi.com/archives/xfs/2008-10/msg00119.html fixes. After this has been included for a while (say a release), I plan to remove the watchdog feature of the xfsaild so the once-per-second-per-XFS-filesystem wakeup will go away then.

It could be, but I didn't want to have to redo that reviewed patch series. I've only hit this problem once in the past 6 weeks so I thought adding a new patch rather than modifying patches to add the fix was a better way to go.... I can integrate it if you want....

It appears that switching between SLAB and SLUB seems to turn off slab/slub memory poisoning, so i dÆŁdn't realise I'd be running for some time without poisoning turned on. Once I turned poisoning back on I found this use-after-free immediately on the first unmount trying to reclaim a clean realtime bitmap inode. With this patch, the netire patchset that I posted yesterday passes xfsqa with memory poisoning turned on. Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: Prevent use-after-free caused by synchronous inode reclaim With the combined linux and XFS inode, we need to ensure that the combined structure is not freed before the generic code is finished with the inode. As it turns out, there is a case where the XFS inode is freed before the linux inode - when xfs_reclaim() is called from ->clear_inode() on a clean inode, the xfs inode is freed during that call. The generic code references the inode after the ->clear_inode() call, so this is a use after free situation. Fix the problem by moving the xfs_reclaim() call to ->destroy_inode() instead of in ->clear_inode(). This ensures the combined inode structure is not freed until after the generic code has finished with it. --- fs/xfs/linux-2.6/xfs_super.c | 32 ++++++++++++++------------------ 1 files changed, 14 insertions(+), 18 deletions(-) diff --git a/fs/xfs/linux-2.6/xfs_super.c b/fs/xfs/linux-2.6/xfs_super.c index b893f8c..7e5a9b7 100644 --- a/fs/xfs/linux-2.6/xfs_super.c +++ b/fs/xfs/linux-2.6/xfs_super.c @@ -875,13 +875,18 @@ xfs_fs_alloc_inode( } /* - * we need to provide an empty inode free function to prevent - * the generic code from trying to free our combined inode. + * Now that the generic code is guaranteed not to be accessing + * the linux inode, we can reclaim the inode. */ STATIC void xfs_fs_destroy_inode( struct inode *inode) { + xfs_inode_t *ip = XFS_I(inode); + + XFS_STATS_INC(vn_reclaim); + if (xfs_reclaim(ip)) + panic("%s: cannot reclaim 0x%p\n", __func__, inode); } /* @@ -958,22 +963,13 @@ xfs_fs_clear_inode( { xfs_inode_t *ip = XFS_I(inode); - /* - * ip can be null when xfs_iget_core calls xfs_idestroy if we - * find an inode with di_mode == 0 but without IGET_CREATE set. - */ - if (ip) { - xfs_itrace_entry(ip); - XFS_STATS_INC(vn_rele); - XFS_STATS_INC(vn_remove); - XFS_STATS_INC(vn_reclaim); - XFS_STATS_DEC(vn_active); - - xfs_inactive(ip); - xfs_iflags_clear(ip, XFS_IMODIFIED); - if (xfs_reclaim(ip)) - panic("%s: cannot reclaim 0x%p\n", __func__, inode); - } + xfs_itrace_entry(ip); + XFS_STATS_INC(vn_rele); + XFS_STATS_INC(vn_remove); + XFS_STATS_DEC(vn_active); + + xfs_inactive(ip); + xfs_iflags_clear(ip, XFS_IMODIFIED); } STATIC void From owner-xfs@oss.sgi.com Thu Oct 9 00:01:09 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.6 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-r574664 Received: from cuda.sgi.com (cuda1.sgi.com [192.48.168.28]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m997177f014324 for ; Thu, 9 Oct 2008 00:01:09 -0700 X-ASG-Debug-ID: 1223535765-407202fc0000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from bombadil.infradead.org (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 54E84A190BB for ; Thu, 9 Oct 2008 00:02:45 -0700 (PDT) Received: from bombadil.infradead.org (bombadil.infradead.org [18.85.46.34]) by cuda.sgi.com with ESMTP id HrG2jZ18QcxUMcXI for ; Thu, 09 Oct 2008 00:02:45 -0700 (PDT) Received: from hch by bombadil.infradead.org with local (Exim 4.68 #1 (Red Hat Linux)) id 1KnpXp-0007zh-Fy; Thu, 09 Oct 2008 07:02:45 +0000 Date: Thu, 9 Oct 2008 03:02:45 -0400 From: Christoph Hellwig To: xfs@oss.sgi.com, linux-fsdevel@vger.kernel.org X-ASG-Orig-Subj: Re: [PATCH 6/5]: XFS: Prevent use-after-free caused by synchronous inode reclaim Subject: Re: [PATCH 6/5]: XFS: Prevent use-after-free caused by synchronous inode reclaim Message-ID: <20081009070245.GA16621@infradead.org> References: <1223416332-7026-1-git-send-email-david@fromorbit.com> <20081009042134.GD9597@disturbed> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20081009042134.GD9597@disturbed> User-Agent: Mutt/1.5.18 (2008-05-17) X-SRS-Rewrite: SMTP reverse-path rewritten from by bombadil.infradead.org See http://www.infradead.org/rpr.html X-Barracuda-Connect: bombadil.infradead.org[18.85.46.34] X-Barracuda-Start-Time: 1223535767 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: -1.42 X-Barracuda-Spam-Status: No, SCORE=-1.42 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests=MARKETING_SUBJECT X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.7610 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.60 MARKETING_SUBJECT Subject contains popular marketing words On Thu, Oct 09, 2008 at 03:21:34PM +1100, Dave Chinner wrote: > Folks, > > The following patch fixes a use after free I just found. > It appears that switching between SLAB and SLUB seems to > turn off slab/slub memory poisoning, so i d??dn't realise > I'd be running for some time without poisoning turned on. > Once I turned poisoning back on I found this use-after-free > immediately on the first unmount trying to reclaim a clean > realtime bitmap inode. > > With this patch, the netire patchset that I posted yesterday > passes xfsqa with memory poisoning turned on.

In fact given that xfs_reclaim is quite OS dependent we might just merge the content directly into destroy_inode.

Yeah, I was thinking of doing exactly that in this patch, but I figured that I'd just do the minimum needed to fix the bug because we're getting close to the next merge window.

I think we need the timeout for the case someone dirties so much data with mmap, hence the freeze process is swapped out and cannot unfreeze.

The problem there is that the delalloc state is checked by looking at the bufferhead, and by the time we get to ->releasepage the buffer heads have already gone through discard_buffer() and lost the buffer_delay() flag. IIRC I had a patch that did the delalloc conversion correctly in ->releasepage by utilising a custom ->invalidatepage callouut, but the performance overhead was very bad because it is done a page at a time.

That's not exactly what I meant or thought I was suggesting. What I thought I suggested was to do the above ENOSPC swizzling for the non-blocking case, but still throw away pages in the blocking flush case. That is, remove the first two hunks of the patch, and just use the third hunk. That way we don't introduce entertaining new ENOSPC problems by retaining the current behaviour, but we still fix the prolonged depletion of the reserve pool by delalloc reservations which seemed to be the cause of all the ENOSPC problems.

But this can be the case not only for buffers where the barrier failed, but also the first buffer of a split log write in case of a log wraparound. Due to the disabled barriers we can easily get directory corruption on unclean shutdowns. So instead of using this check add a new buffer flag for failed barrier writes. This is a regression vs 2.6.26 caused by patch to use the right macro to check for the ORDERED flag, as we previously got true returned for every buffer. Thanks to Toei Rei for reporting the bug.

Could this accelerate tar -xf linux-2.6.26.tar.gz rm -r linux-2.6.26 ? A student in the Linux Performance Tuning course I hold this week compared this with ext3, even with the improved mkfs.xfs options (but without lazy-count=1, cause mkfs.xfs from Debian Etch is too old) and even with noop as IO scheduler. AFAIR XFS took roughly 3-4 times as long as Ext3, I did not note the exact numbers. This was with 2.6.25. I can repeat the test locally with 2.6.26.5 if wanted.

All sizeof operations on the dinode_core either really wanted the icdinode and are switched to that one, or had already added the size of the agi unlinked list pointer. Later both will be replaced with helpers once we get the larger CRC-enabled dinode. Removing the data and attribute fork unions also has the advantage that xfs_dinode.h doesn't need to pull in every header under the sun. While we're at it also add some more comments describing the dinode structure.

XFS journals transactions almost immediately, whereas ext3 gathers lots of changees in memory and checkpoints infrequently. Hence XFS writes a lot more to the journal and is hence slower. The dynamic extent tracking is a necessary step to moving the XFS journalling to a more checkpoint-like setup which would perform much less journal I/O and hence run substantially faster....

FWIW, here's the discussion: http://oss.sgi.com/archives/xfs/2008-04/msg00542.html I'm not saying that we ѕhould be fixing this right now, but this is the underlying problem that is causing the direct I/O read to trip over stale delalloc extents once they've been invalidated.

Message-Id: <20081010041758.C521E58C52B5@chook.melbourne.sgi.com> Date: Fri, 10 Oct 2008 15:17:58 +1100 (EST) From: pleckie@sgi.com (Peter Leckie) don't block in xfs_qm_dqflush() during async writeback. Normally dquots are written back via delayed write mechanisms. They are flushed to their backing buffer by xfssyncd, which is then pushed out by either AIL or xfsbufd flushing. The flush from the xfssyncd is supposed to be non-blocking, but xfs_qm_dqflush() always waits for pinned duots, which means that it will block for the length of time it takes to do a synchronous log force. This causes unnecessary extra log I/O to be issued whenever we try to flush a busy dquot. Avoid the log forces and blocking xfssyncd by making xfs_qm_dqflush() pay attention to what type of sync it is doing when it sees a pinned dquot and not waiting when doing non-blocking flushes.

Clean up the way the maximum and minimum records for the btree blocks are calculated. For the alloc and inobt btrees all the values are pre-calculated in xfs_mount_common, and we switch the current loop around the ugly generic macros that use cpp token pasting to generate type names to two small helpers in normal C code. For the bmbt and bmdr trees these helpers also exist, but can be called during runtime, too. Here we also kill various macros dealing with them and inline the logic into the get_minrecs / get_maxrecs / get_dmaxrecs methods in xfs_bmap_btree.c. Note that all these new helpers take an xfs_mount * argument which will be needed to determine the size of a btree block once we add support for extended btree blocks with CRCs and other RAS information.

But this can be the case not only for buffers where the barrier failed, but also the first buffer of a split log write in case of a log wraparound. Due to the disabled barriers we can easily get directory corruption on unclean shutdowns. So instead of using this check add a new buffer flag for failed barrier writes. This is a regression vs 2.6.26 caused by patch to use the right macro to check for the ORDERED flag, as we previously got true returned for every buffer. Thanks to Toei Rei for reporting the bug.

This is an important fix posted by Christoph Hellwig today. Without this fix, XFS can turn off barriers when we wrap our ondisk log.

If there is a permanent error then a metadata or log I/O will probably soon fail and that will issue a force shutdown anyway and that will cause us to discard the pages. I just don't get why silently discarding writes is a good idea. And even if we issue a warning the user has no idea which writes were discarded. Are you worried we will deadlock the system by running out of pages?

Are you sure? So a synchronous flush of the file would still discard data and leave the delayed allocation. A flushinval (before a direct I/O) would get an error and fail but a second flushinval would succeed (because it would not try to flush the same page) and we'd hit the BUG_ON with direct I/O.

This will only show up on some operations like touch because most read-only checks are done by the VFS which things this filesystem is r/w. Eventually we should replace the XFS read-only flag with a helper that always checks the VFS flag to make sure they can never get out of sync. Bug reported and fix verified by Marcel Beister on #xfs.

If this is not the relevant mail list, please let me know. I suspect that my problem is xfs related, thus I select this mailing list. I have a system that recently upgraded it's kernel to 2.6.25.14. The system's previous kernel was 2.6.18.-8.el5. With the previous kernel, I have no problem with executing the following commands when the system is in operation. Note that the /mnt/mountpoint is mounted on a XFS file system. mount -o rw,remount /mnt/mountpoint mount -o ro,remount /mnt/mountpoint With kernel 2.6.25.14, however, the mount command may be hang when changing from rw to ro. When this happen, system is very sluggish. Even the "shutdown -r now" command is not taken. The only way to get out of this hang is by manually pressing the power button Your sugguestion is greatly appreciated.

When this happen, system is very sluggish. That's because the remount,ro is actually flushing all the dirty data to disk in 2.6.25. There is also a check to catch when the remount,ro fails to clean everything that is dirty - that's probably what is triggering. Do you have an oops in the dmesg log when mount hangs?

When this happen, system is very sluggish. That's because the remount,ro is actually flushing all the dirty data to disk in 2.6.25. There is also a check to catch when the remount,ro fails to clean everything that is dirty - that's probably what is triggering. Do you have an oops in the dmesg log when mount hangs?

folks, Looks like Christoph is having problems posting to the list; the spam filter is dropping all his mail. In the mean time, here's a fix for an oops in the tracing code as a result of the last check ins. I didn't see this because the "combine inodes" patches removes xfs_icount altogether. If that series is going to be included in the current round of checkins then this patch probably isn't needed. Cheers, Dave. -- Dave Chinner david@fromorbit.com From: Christoph Hellwig We can only read inode->i_count if the inode is actually there and not a NULL pointer.

The agreed plan for 2.6.28 still has the following patchsets to go in: . Combine the XFS and Linux inode structures V2 . Track reclaimable inodes in inode cache . AIL cleanup and bug fixes . Account for allocated blocks when expanding directories . Check for valid transaction headers in recovery . fix remount rw with unrecognized options It's starting to look like a pretty aggressive merge and QA schedule. Dave, is it worth doing any testing until these are *all* merged?

When this happen, system is very sluggish. That's because the remount,ro is actually flushing all the dirty data to disk in 2.6.25. There is also a check to catch when the remount,ro fails to clean everything that is dirty - that's probably what is triggering. Do you have an oops in the dmesg log when mount hangs?

When the system is not being used, I can finish the loop of 100 mount operations; however, when the system is being used, a couple of the above mount commands, even manually, will cause the system to hang.

I do make sure every patch compiles given the config options a mainline kernel allows. However, the CONFIG_XFS_TRACE option is not present in mainline-derived kernels so it's not obvious when problems occur inside code that isn't easily configurable on such a kernel.... As it is, I haven't done a CONFIG_XFS_TRACE build for several months because I've found that I haven't needed tracing to find problems esoteric problems. Using watchpoints, breakpoints and single stepping catches problems as they occur rather than needing tracing to try to work out what went wrong after a problem has occurred.

Ok. So when a software update needs to be done, the filesystem is made writable, correct? But once the update is done, it then gets made RO again? how much data gets written when an update is run? > Is the filesystem busy at the time the ro,remount is run? > (e.g. any large background writes occurring?) > > [Andrew Ngo]Yes.

Well, I'd suggest that we probably should turn all the trace points into markers so that systemtap can hook them and you can write probes to extract the traces in real-time.... > I'd really like to be able to access tracing output via proc > instead of just within kdb, > as I have used in the past with Greg Banks qtrace patches. Perhaps extending something like: Documentation/ftrace.txt would be the appropriate way to go to acheive this. I think in the past Christoph has suggested switching the ktrace code over a relayfs mechanism and providing a userspace decoder would allow both kdb and userspace to access the same traces...

I'd really like to see 1 and 2 and volunter to help sorting out any fallout. Not entirely sure about the AIL patches - they seem ready but at least they don't have much impact on everything else. So if you really want to reduce the amount of patches those would be the ones.

[Andrew Ngo]Actually, we only perform the mount ro after we patch the softwarfe. At that time, we have full control of the screen which means that the system is not busy; but I don't know if the file system is still busy under the cover.

Ok. So when a software update needs to be done, the filesystem is made writable, correct?

Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: avoid all reclaimable inodes in xfs_sync_inodes_ag If we are syncing data in xfs_sync_inodes_ag(), the VFS inode must still be referencable as the dirty data state is carried on the VFS inode. hence if we can't get a reference via igrab(), the inode must be in reclaim which implies that it has no dirty data attached. Leave such inodes to the reclaim code to flush the dirty inode state to disk and so avoid attempting to access the VFS inode when it may not exist in xfs_sync_inodes_ag().

The buffer and the buffer log item look sane but the ktrace hanging off the buffer log item is hosed. It's the first time I've seen it and it may just be a coincidence.

This means that we need initialise a struct inode from a context outside alloc_inode() as it is no longer used by XFS. Factor and export the struct inode initialisation code from alloc_inode() to inode_init_always() as a counterpart to inode_init_once(). i.e. we have to call this init function for each inode instantiation (always), as opposed inode_init_once() which is only called on slab object instantiation (once).

This means that we need initialise a struct inode from a context outside alloc_inode() as it is no longer used by XFS. After inode allocation and initialisation, we need to add the inode to the superblock list, the in-use list, hash it and do some accounting. This all needs to be done with the inode_lock held and there are already several places in fs/inode.c that do this list manipulation. Factor out the common code, add a locking wrapper and export the function so ti can be called from XFS.

As it turns out, there is a case where the XFS inode is freed before the linux inode - when xfs_reclaim() is called from ->clear_inode() on a clean inode, the xfs inode is freed during that call. The generic code references the inode after the ->clear_inode() call, so this is a use after free situation. Fix the problem by moving the xfs_reclaim() call to ->destroy_inode() instead of in ->clear_inode(). This ensures the combined inode structure is not freed until after the generic code has finished with it.

Well, Daven unfortunately can't be bothered to use the same tree as everyone else. But I made it pretty clear in the patch that it is needed for the series when using a ptools/cvs style tree, and that it's harmless to apply it ASAP even without those bits.

Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: avoid all reclaimable inodes in xfs_sync_inodes_ag If we are syncing data in xfs_sync_inodes_ag(), the VFS inode must still be referencable as the dirty data state is carried on the VFS inode. hence if we can't get a reference via igrab(), the inode must be in reclaim which implies that it has no dirty data attached. Leave such inodes to the reclaim code to flush the dirty inode state to disk and so avoid attempting to access the VFS inode when it may not exist in xfs_sync_inodes_ag(). Version 2: o change igrab logic to be more linear o remove initial reclaimable inode check now that we are using igrab() failure to detect inodes in reclaim o assert that igrab failure occurs only on reclaimable inodes o clean up inode locking - only grab the iolock if we are doing a SYNC_DELWRI call and we have a dirty inode.

If we try to find the next inode in the AG by adding one to the inode number, we increment the inode number past the size of the AG. The result is that the macro XFS_INO_TO_AGINO() will strip the AG portion of the inode number and return an inode number of zero. That is, instead of terminating the lookup loop because we hit the inode number went outside the valid range for the AG, the search index returns to zero and we start traversing the radix tree from the start again. This results in an endless loop in xfs_sync_inodes_ag(). Fix it be detecting if the new search index decreases as a result of incrementing the current inode number. That indicate an overflow and hence that we have finished processing the AG so we can terminate the loop.

This leads to problems where an allocation group has only enough blocks for *some* of the allocations required for the directory modification. After the first N allocations, the remaining blocks in the allocation group drops below the total reservation, and subsequent allocations fail because the allocator will not allow the allocation to proceed if the AG does not have the enough blocks available for the entire allocation total. This results in an ENOSPC occurring after an allocation has already occurred. This results in aborting the directory operation (leaving the directory in an inconsistent state) and cancelling a dirty transaction, which results in a filesystem shutdown. Avoid the problem by reflecting the number of blocks allocated in any directory expansion in the total number of blocks available to the modification in progress. This prevents a directory modification from being aborted part way through with an ENOSPC.

Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: avoid all reclaimable inodes in xfs_sync_inodes_ag If we are syncing data in xfs_sync_inodes_ag(), the VFS inode must still be referencable as the dirty data state is carried on the VFS inode. hence if we can't get a reference via igrab(), the inode must be in reclaim which implies that it has no dirty data attached. Leave such inodes to the reclaim code to flush the dirty inode state to disk and so avoid attempting to access the VFS inode when it may not exist in xfs_sync_inodes_ag(). Version 4: o don't reference liinux inode untiil after igrab() succeeds Version 3: o converted unlock/rele to an xfs_iput() call. Version 2: o change igrab logic to be more linear o remove initial reclaimable inode check now that we are using igrab() failure to find reclaimable inodes o assert that igrab failure occurs only on reclaimable inodes o clean up inode locking - only grab the iolock if we are doing a SYNC_DELWRI call and we have a dirty inode. --- fs/xfs/linux-2.6/xfs_sync.c | 75 ++++++++++-------------------------------- 1 files changed, 18 insertions(+), 57 deletions(-) diff --git a/fs/xfs/linux-2.6/xfs_sync.c b/fs/xfs/linux-2.6/xfs_sync.c index 08b2acf..39ed7f3 100644 --- a/fs/xfs/linux-2.6/xfs_sync.c +++ b/fs/xfs/linux-2.6/xfs_sync.c @@ -63,25 +63,16 @@ xfs_sync_inodes_ag( int error = 0; int last_error = 0; int fflag = XFS_B_ASYNC; - int lock_flags = XFS_ILOCK_SHARED; if (flags & SYNC_DELWRI) fflag = XFS_B_DELWRI; if (flags & SYNC_WAIT) fflag = 0; /* synchronous overrides all */ - if (flags & SYNC_DELWRI) { - /* - * We need the I/O lock if we're going to call any of - * the flush/inval routines. - */ - lock_flags |= XFS_IOLOCK_SHARED; - } - do { struct inode *inode; - boolean_t inode_refed; xfs_inode_t *ip = NULL; + int lock_flags = XFS_ILOCK_SHARED; /* * use a gang lookup to find the next inode in the tree @@ -109,22 +100,6 @@ xfs_sync_inodes_ag( break; } - /* - * skip inodes in reclaim.

It fixes a regression in the recent remount recoding where remounting say from ro to rw allows the xfs flags to be out of sync with the vfs flags, resulting in failures for some programs such as touch (which end up calling xfs_setattr). The fix is a very minor and clear. Thanks, Tim.

Bug fix verified by updated xfstests/189.

Here is my story: I have openfiler installed with LVM and a single xfs partition over 7 sata hdd's. Yesterday I discovered that I can't write any files to the xfs partition, even if there was 1,2Tb free space. I've googled alot and modified the label of all partitions to GPT (that seemed to be the problem with xfs, or so I've imagined and I've used parted - mklabel). After that I've rebooted and all data was gone. The parted program changed the partitions UUID's. I've manualy set original partitions UUID from lvm backup's and restored the volume group. The partition from the volume group was there but XFS can't mount the filesystem.

Sorry. Please include the following patch for 2.6.27.1 stable release as suggested by Christoph Hellwig and Eric Sandeen. It fixes a regression in the recent remount recoding where remounting say from ro to rw allows the xfs flags to be out of sync with the vfs flags, resulting in failures for some programs such as touch (which end up calling xfs_setattr). The fix is a very minor and clear. Thanks, Tim. Date: Sun, 12 Oct 2008 14:30:44 +0200 From: Christoph Hellwig To: xfs@oss.sgi.com Subject: [PATCH] fix remount rw with unrecognized options When we skip unrecognized options in xfs_fs_remount we should just break out of the switch and not return because otherwise we may skip clearing the xfs-internal read-only flag. This will only show up on some operations like touch because most read-only checks are done by the VFS which thinks this filesystem is r/w. Eventually we should replace the XFS read-only flag with a helper that always checks the VFS flag to make sure they can never get out of sync. Bug reported and fix verified by Marcel Beister on #xfs. Bug fix verified by updated xfstests/189.

Message-Id: <20081016043401.B135458FA22B@chook.melbourne.sgi.com> Date: Thu, 16 Oct 2008 15:34:01 +1100 (EST) From: lachlan@sgi.com (Lachlan McIlroy) Use a cursor for AIL traversal. To replace the current generation number ensuring sanity of the AIL traversal, replace it with an external cursor that is linked to the AIL. Basically, we store the next item in the cursor whenever we want to drop the AIL lock to do something to the current item. When we regain the lock. the current item may already be free, so we can't reference it, but the next item in the traversal is already held in the cursor. When we move or delete an object, we search all the active cursors and if there is an item match we clear the cursor(s) that point to the object. This forces the traversal to restart transparently. We don't invalidate the cursor on insert because the cursor still points to a valid item. If the intem is inserted between the current item and the cursor it does not matter; the traversal is considered to be past the insertion point so it will be picked up in the next traversal. Hence traversal restarts pretty much disappear altogether with this method of traversal, which should substantially reduce the overhead of pushing on a busy AIL.

We can replace the use of xfs_trans_first_ail() in xfs_log_need_covered() as it is only checking if the AIL is empty. We can do that with a call to xfs_trans_ail_tail() instead, where a zero LSN returned indicates and empty AIL...

Ah, misread the trace: >> - agno = 0 >> entry "All" in shortform directory 186 references free inode 136 >> junking entry "All" in directory inode 186 Inode 136 is the "All" directory - for some reason, it's marked as deleted.

A shutdown in a directory transaction. Have you applied the fix to the directory block allocation transaction accounting that was one of the last patches I posted?

Currently we just assert that header magic number matches, but in production systems that is not present and we add a corrupted transaction to the list to be processed. This results in a kernel oops later when processing the corrupted transaction. Instead, if we detect a corrupted transaction, abort recovery and leave the user to clean up the mess that has occurred.

At least I have only QAed the whole patchkit, and from the issues here it seems like Dave did the same. And with that it would also be very good if there was any chance Dave and me (and all others) could actually access the current tree. The ptools -> CVS export has been broken for mor than two days, and there is no uptodate git tree eiter, so us external developers are completely tapping in the dark vs the current tree.

The only thing I've modified was "write core.mode 040755" and after some time of "printing inodes" I've runned xfs_repair in modify mode but nothing good happened. Almost all inodes have "next_unlinked" set to null and the time in 1 Jan 1970. The All folder has the time in 2008 but even after xfs_repair moved the folder in lost+found it's still empty and named 186. The conclusion is: all data lost? If so what is the best way to reformat the volume to not have the same problems again? The "no space left on the device" and "lose all data" problems? I have an UPS on that server, so the bad shutdown corruption will not happen. I know all the files and folders are still there because no write opperations occured but I don't have a way to read them because the filesystem can't find the "connections"...

If you have no backup and the data is important enough for you, you can try to use photorec from the testdisk package, foremost or magicrescue. photorec seems to have the most formats supported out of the box, foremost and magicrescue can be extended via recipes. Don't expect to be able to recover file and directory names tough. With photorec I was able to recover photos from a smartmedia card that showed as empty in Linux while the camera showed the photos on it. -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7 From owner-xfs@oss.sgi.com Thu Oct 16 11:09:03 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-1.6 required=5.0 tests=AWL,BAYES_00,TRACKER_ID autolearn=no version=3.3.0-r574664 Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9GI92Tv001296 for ; Thu, 16 Oct 2008 11:09:03 -0700 X-ASG-Debug-ID: 1224180645-028402db0000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from bombadil.infradead.org (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id E6D5D1418C67; Thu, 16 Oct 2008 11:10:45 -0700 (PDT) Received: from bombadil.infradead.org (bombadil.infradead.org [18.85.46.34]) by cuda.sgi.com with ESMTP id 2YQmMibyvIUOeKdr; Thu, 16 Oct 2008 11:10:45 -0700 (PDT) Received: from hch by bombadil.infradead.org with local (Exim 4.68 #1 (Red Hat Linux)) id 1KqXJ6-0005lP-O2; Thu, 16 Oct 2008 18:10:44 +0000 Date: Thu, 16 Oct 2008 14:10:44 -0400 From: Christoph Hellwig To: Greg KH Cc: Tim Shimmin , stable@kernel.org, linux-kernel@vger.kernel.org, xfs@oss.sgi.com X-ASG-Orig-Subj: Re: [stable] [PATCH] XFS fix remount rw with unrecognized options Subject: Re: [stable] [PATCH] XFS fix remount rw with unrecognized options Message-ID: <20081016181044.GA16092@infradead.org> References: <20081016002926.D912558FA22B@chook.melbourne.sgi.com> <20081016173529.GA13038@kroah.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20081016173529.GA13038@kroah.com> User-Agent: Mutt/1.5.18 (2008-05-17) X-SRS-Rewrite: SMTP reverse-path rewritten from by bombadil.infradead.org See http://www.infradead.org/rpr.html X-Barracuda-Connect: bombadil.infradead.org[18.85.46.34] X-Barracuda-Start-Time: 1224180645 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: 0.67 X-Barracuda-Spam-Status: No, SCORE=0.67 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests=TRACKER_ID X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.8097 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 2.70 TRACKER_ID BODY: Incorporates a tracking ID number On Thu, Oct 16, 2008 at 10:35:29AM -0700, Greg KH wrote: > Is this patch already in Linus's tree?

If so, when? :) (just for the record; it didn't oops, it shut down the filesystem and gave you a backtrace to the error...) It's trying to get a buffer for a directory leaf block from disk, and it's finding that the magic number is bad. What's a little odd is that the buffer it dumped out looks like the beginning of a perfectly valid superblock for your filesystem (magic, block size, and block count all match). If you printk the "bno" variable right around line 2106 in xfs_da_btree.c, can you see what you get? creating an xfs_metadump of the filesystem for examination on a non-arm box might also be interesting.

But XFS_ERROR is used throughout the function. I've found the whole idea of when and when not to use XFS_ERROR annoying :) I've never used it (other than calling it to stay consistent with the code). Looking at the code, it is used to BUG and print a msg on particular error codes set in xfs_etrap[] - and it does this in xfs_error_trap(). Can one not decide to do this at any error point? I can't see where we hook in to set up xfs_etrap. > #ifdef DEBUG > #define XFS_ERROR_NTRAP 10 > extern int xfs_etrap[XFS_ERROR_NTRAP]; > extern int xfs_error_trap(int); > #define XFS_ERROR(e) xfs_error_trap(e) > #else > #define XFS_ERROR(e) (e) > #endif Cheers, Tim.

I can't think of how. The layers above XFS are symmetric: alloc_inode() inode_init_always() security_inode_alloc() ..... security_inode_free() ->destroy_inode() So the filesystems should never, ever need to know about the security context attached to the inode. The changes that introduced inode_init_always() do not change this symmetry - we do: xfs_inode_alloc() inode_init_always() security_inode_alloc() ..... security_inode_free() ->destroy_inode() And we should have this symmetry everywhere. Hmmmm - maybe the xfs_iget_cache_miss failure paths where we call xfs_idestroy() could leak contexts. We should really call xfs_iput() because we have an initialised linux inode at this point and so we need to go through destroy_inode(). I'll have a bit more of a look, but this doesn't seem to account for the huge number of leaked contexts you reported....

You break into the debugger, modify the xfs_etrap array to contain the set of errors you want to catch, then continue onwards. I've used this several times in the past couple of months to locate the source of strange ENOSPC errors... The conceptual idea is that every point where an error is first detected gets wrapped with XFS_ERROR() so you don't need to sprinkle printk's all through the code to find where the error is coming from. ISTR the Irix kernel debugger had a command to set the values in the etrap array - if it did it never got ported to kdb....

Patch below that replaces xfs_idestroy() with IRELE() to destroy the inode via the normal iput() path. It also fixes a second issue that I found by inspection related to security contexts as a result of hooking up ->destroy_inode. It's running QA now. FWIW, I'm not sure if this patch will apply cleanly - I'm still running of my stack of patches and not what has been checked into ptools. Any idea of when all the patches in ptools will be pushed out to the git tree?

And now with the patch. -- Dave Chinner david@fromorbit.com XFS: Ensure that we destroy the linux inode after initialisation Now that XFS initialises the struct inode prior to completing all checks and insertion into caches, we need to destroy that state if we fail to instantiate the inode completely. Hence we cannot just call xfs_idestroy() to clean up state when such an occurrence happens - we need to go through the normal reclaim path by dropping the reference count on the linux inode we now hold. This will prevent leaking security contexts on failed lookups. Also, now that we have a ->destroy_inode() method, failing to allocate a security context for the inode will result in the xfs_inode being freed via the ->destroy_inode() path internally to inode_init_always(). Rearrange xfs_inode_alloc() to initialise the xfs_inode prior to attempting to initialise the VFS inode so that the reclaim path will work and remove the freeing of the inode in xfs_inode_alloc() if VFS inode initialisation fails.

You might want to change the order that certain patches have been committed - the changes to the fs/inode.c needed to be committed before the changes to fs/xfs/xfs_inode.c that use them. They've been committed the wrong way around and about 20 commits apart, so there's significant region in the commit history where the kernel will fail to build. Given the distance between the commits, there's a fair chance that a git bisect could land in this range of compiliation failures. Any chance of redoing these commits before you push to Linus so that they are ordered correctly in the git tree?

(correlates with the "bad" magic that was seen, because block 0 is the superblock, but doesn't make sense because we were trying to read a directory leaf block, in theory) If you unmount & remount, does the ls work then? >> creating an xfs_metadump of the filesystem for examination on a >> non-arm box might also be interesting. > > http://www.cyrius.com/tmp/dump5 > (11 MB) Thanks. xfs_repair on x86 shows no errors; however it won't mount normally (bad log clientid) - but mount -o norecovery,ro and subsequent ls works fine (at first I thought filenames were badly scrambled but then remembered that xfs_metadump does this by default ;)) The remaining problem that I know of on some arm architectures is a vmap cache aliasing problem that usually shows up as log corruption; that may explain the bad clientid thing but not sure why we're reading block 0 above. Do you know what cachepolicy you're booted with? If it's writeallocate, you might try cachepolicy=writeback, otherwise try cachepolicy=uncached (which will be horribly slow) and see if the problem goes away or not; it'd be a clue. -Eric From owner-xfs@oss.sgi.com Fri Oct 17 09:39:36 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.5 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-r574664 Received: from cuda.sgi.com (cuda2.sgi.com [192.48.168.29]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9HGdYR4007198 for ; Fri, 17 Oct 2008 09:39:36 -0700 X-ASG-Debug-ID: 1224261677-0de001750000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from bombadil.infradead.org (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id B524B50DA3E for ; Fri, 17 Oct 2008 09:41:18 -0700 (PDT) Received: from bombadil.infradead.org (bombadil.infradead.org [18.85.46.34]) by cuda.sgi.com with ESMTP id ws6roL0mf6bRaiKU for ; Fri, 17 Oct 2008 09:41:18 -0700 (PDT) Received: from hch by bombadil.infradead.org with local (Exim 4.68 #1 (Red Hat Linux)) id 1KqsO4-0000kj-LS; Fri, 17 Oct 2008 16:41:16 +0000 Date: Fri, 17 Oct 2008 12:41:16 -0400 From: Christoph Hellwig To: Alexander Beregalov Cc: xfs@oss.sgi.com, linux-next@vger.kernel.org, LKML X-ASG-Orig-Subj: Re: BUG: sleeping function called from invalid context at kernel/rwsem.c:131 XFS?

As far as the kernel and most userspace is concerned this works perfectly, but applications still using really old stat and readdir interfaces will get an EOVERFLOW error when hitting an inode number not fitting into 32 bits (that problem of course also exists when using these applications on a 64bit kernel). Note that because inode64 is simply a mount option we can currently mount a filesystem having > 32 bit inode numbers and cause a variety of problems, all this is solved but this patch which enables XFS_BIG_INUMS, even when inode64 is not used.

Today, xfsrestore really threw me a curve ball. I am wondering what went wrong. I had wanted to restore from an old backup some directories that I discovered I had need of. I used the following syntax to get the restore started: xfsrestore -J -E -f /mnt/ext_backup/ldslnx01/20061220/data -s shares/data -i -v verbose /srv I selected some directories to restore through the interactive interface, then allowed it to restore the specified files. What it ended up doing, HOWEVER, was to restore every file present in that old backup that was no longer on disk! Thus, what went wrong?

Setting cachepolicy=uncached should make aliasing issues disappear. If you're still seeing issues with cachepolicy=uncached, it's likely some other issue.

Oh ok. In userspace, we use it for opening directories on xfsdump via jdm_open in order to do bulkstat driven dirent dumping. We also use it in xfsrestore - though I am not convinced we should - it was initially done for "performance" reasons apparently. --Tim From owner-xfs@oss.sgi.com Sun Oct 19 18:16:27 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: *** X-Spam-Status: No, score=3.1 required=5.0 tests=BAYES_50,HTML_MESSAGE, J_CHICKENPOX_43 autolearn=no version=3.3.0-r574664 Received: from cuda.sgi.com (cuda1.sgi.com [192.48.168.28]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9K1GRMV019291 for ; Sun, 19 Oct 2008 18:16:27 -0700 X-ASG-Debug-ID: 1224465489-246802400000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mail.ramunia.com (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 1DC63AC8E00 for ; Sun, 19 Oct 2008 18:18:10 -0700 (PDT) Received: from mail.ramunia.com ([58.26.86.165]) by cuda.sgi.com with ESMTP id eHbBgNqhaFVn6eSo for ; Sun, 19 Oct 2008 18:18:10 -0700 (PDT) Received: (qmail 9360 invoked by uid 509); 20 Oct 2008 09:12:56 +0800 Received: from 58.26.120.2 by mail.ramunia.com (envelope-from , uid 508) with qmail-scanner-1.25-st-qms (clamdscan: 0.91.2/4429. spamassassin: 3.0.2. perlscan: 1.25-st-qms.

I also hit this panic where we have taken a reference on an inode that has I_CLEAR set. I suspect we've made it into xfs_iget_cache_hit() and found an inode with XFS_IRECLAIMABLE set and since we don't call igrab() we don't do the I_CLEAR check.

Yeah I'll try to get them back in the right order. Our merge tools conveniently missed anything outside fs/xfs so I didn't realise I had missed them until after I merge all the XFS mods. I just wanted to get something out for linux-next and also since the cvs tree was busted. Out of curiosity Dave, why didn't you send those changes directly to Linus?

There's not a lot to go on here, but it sounds like it's possibly an lvm snapshot issue, not an xfs issue, to me. Can you test another filesystem temporarily to see if you see the same slowdown when a snapshot is active? When a snapshot is active, it's doing copy on write, which will slow things down to some degree. -Eric From owner-xfs@oss.sgi.com Sun Oct 19 19:55:27 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.2 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-r574664 Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9K2tRaB027947 for ; Sun, 19 Oct 2008 19:55:27 -0700 X-ASG-Debug-ID: 1224471430-067201800000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from sandeen.net (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id EC9AF1B609A6 for ; Sun, 19 Oct 2008 19:57:11 -0700 (PDT) Received: from sandeen.net (sandeen.net [209.173.210.139]) by cuda.sgi.com with ESMTP id lxjsUFxoee4XSDn3 for ; Sun, 19 Oct 2008 19:57:11 -0700 (PDT) Received: from liberator.sandeen.net (liberator.sandeen.net [10.0.0.4]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (No client certificate requested) by sandeen.net (Postfix) with ESMTP id 8F7FAAC359B; Sun, 19 Oct 2008 21:57:09 -0500 (CDT) Message-ID: <48FBF385.2010709@sandeen.net> Date: Sun, 19 Oct 2008 21:57:09 -0500 From: Eric Sandeen User-Agent: Thunderbird 2.0.0.17 (Macintosh/20080914) MIME-Version: 1.0 To: Muhammad Fakhrul Rozi Bin Mohd Seth CC: xfs-oss X-ASG-Orig-Subj: Re: XFS slow performance Subject: Re: XFS slow performance References: <48FBDC47.5080700@ramunia.com> <48FBEBFA.30200@sandeen.net> <48FBED80.60604@ramunia.com> In-Reply-To: <48FBED80.60604@ramunia.com> Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: sandeen.net[209.173.210.139] X-Barracuda-Start-Time: 1224471431 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: -2.02 X-Barracuda-Spam-Status: No, SCORE=-2.02 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.8312 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- Muhammad Fakhrul Rozi Bin Mohd Seth wrote: > Thanks for the reply; No problem; please keep the list on cc: so that others with similar problems will have something to find on google :) > Yes i have test the other's and it is more worst than XFS. > So here the snapshot is provide by the LVM not the XFS itself?

I suspect we've made it into xfs_iget_cache_hit() I don't think there is an iput() in that path. The only iput() call should be the IRELE() I added to xfs_iget_cache_miss().

By the time the XFS_IRECLAIMABLE flag is set, I_CLEAR has been set on the VFS inode. It is safe to re-use the inode at this point as the VFS inode has been "destroyed" and hence all we need to do is re-initialise it. We've always done this for inodes in reclaim so we don't have to re-read them off disk... Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: Ensure that we destroy the linux inode after initialisation Now that XFS initialises the struct inode prior to completing all checks and insertion into caches, we need to destroy that state if we fail to instantiate the inode completely. Hence we cannot just call xfs_idestroy() to clean up state when such an occurrence happens - we need to go through the normal reclaim path by dropping the reference count on the linux inode we now hold. This will prevent leaking security contexts on failed lookups. Also, now that we have a ->destroy_inode() method, failing to allocate a security context for the inode will result in the xfs_inode being freed via the ->destroy_inode() path internally to inode_init_always(). Rearrange xfs_inode_alloc() to initialise the xfs_inode prior to attempting to initialise the VFS inode so that the reclaim path will work and remove the freeing of the inode in xfs_inode_alloc() if VFS inode initialisation fails.

Yeah, xfs_setup_inode() is what is doing: inode->i_state = I_NEW|I_LOCK; which happens after the cache miss has been processed. Ok, so the initialisation code needs to clear іnode->i_state during allocation so that iput() does not complain. The i_state field is not accessed by anything until the inode is inserted into the superblock lists, so it should be safe to zero it in xfs_inode_alloc(). I missed that new_inode() returns an inode with a zeroed i_state.... Updated patch below, just starting a QA run on it.

Because trying to co-ordinate an dependent updates in different trees is extremely painful. We'd have to delay the XFS update till the inode patches were in mainline anyway, so it makes little sense to separate them....

On second thoughts, the inode has not been set up properly by this stage, so we can't really even expect to be able to call iput() on it. Hmmmm - maybe the only thing we can do here is call security_inode_free() before xfs_idestroy. Christoph - any opinions on what the best thing to do is?

Calling destroy_inode after exporting it seems most logical. If we want to undo init_inode_once we should have VFS functionality taking care of that, too.

The formatter takes info for 1 extent, a pointer to the user "thing*" and a pointer to a "filled" variable to indicate whether a userspace buffer did get filled in (for fiemap, hole "extents" are skipped). I'm just using the getbmapx struct as a "common denominator" because as far as I can see, it holds all info that any formatters will care about. ("*thing" because fiemap doesn't pass the user pointer around, but rather has a pointer to a fiemap info structure, and helpers associated with it) I'm still working on the fiemap hookup but wanted to put this out for comment.

Yeah, I have no problem for xfsdump as it is driven by bulkstat but for xfsrestore it seems unnecessary. In fact, it can restore to other filesystems so it must only be using this in certain ways on restore. Having a look, yeah it is predicated by: if ( tranp->t_dstdirisxfspr ) and then just uses the fd for XFS_IOC_FSSETDM, XFS_IOC_FSSETXATTR for those xfs-specific things and in the same function it uses the path for non-xfs-specific: utime, chown, chmod So it seems unnecessary to me in restore. --Tim From owner-xfs@oss.sgi.com Mon Oct 20 17:59:54 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-r574664 (2007-09-11) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.4 required=5.0 tests=AWL,BAYES_00,J_CHICKENPOX_14 autolearn=no version=3.3.0-r574664 Received: from relay.sgi.com (relay1.corp.sgi.com [192.26.58.214]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9L0xsD6002057 for ; Mon, 20 Oct 2008 17:59:54 -0700 Received: from larry.melbourne.sgi.com (larry.melbourne.sgi.com [134.14.52.130]) by relay1.corp.sgi.com (Postfix) with SMTP id 709718F8056; Mon, 20 Oct 2008 18:01:33 -0700 (PDT) Received: from [134.14.55.78] (redback.melbourne.sgi.com [134.14.55.78]) by larry.melbourne.sgi.com (950413.SGI.8.6.12/950213.SGI.AUTOCF) via ESMTP id MAA13367; Tue, 21 Oct 2008 12:01:30 +1100 Message-ID: <48FD37C5.9040309@sgi.com> Date: Tue, 21 Oct 2008 12:00:37 +1000 From: Lachlan McIlroy Reply-To: lachlan@sgi.com User-Agent: Thunderbird 2.0.0.17 (X11/20080914) MIME-Version: 1.0 To: Christoph Hellwig CC: xfs@oss.sgi.com Subject: Re: git tree updates....

Thanks for pointing that out - that shouldn't have happened. It wont be going to mainline. The OSS xfs trees are in a bit of a mess and have been for a while. I've been wanting to clean them up but figured it would be easier to wait until we've moved over to git internally and then clone new trees.

Perhaps i_update_core needs to be set so that xfs_iflush_int will proceed and call xfs_synchronize_atime() and somehow that is not happening?? I haven't looked further yet, but I thought I'd ask on the list in case others, such as Christoph and Dave have thoughts on this. Thanks, Tim.

The content of xfs_start_flags gets merged into xfs_parseargs. Calls inbetween don't care and can use mount members instead of the args struct. This patch uncovered that the mount option for shared filesystems wasn't ever exposed on Linux. The code to handle it is #if 0'ed in this patch pending a decision on this feature. I'll send a writeup about it to the list soon.

Then again the current biosize option doesn't make much sense to me as it doesn't set the preferred I/O size as mentioned in the comment next to it but rather the allocation size and thus is identical to the allocsize option (except for the missing logarithm). It's also not documented in Documentation/filesystems/xfs.txt or the mount manpage.

To purge the batch, it just goes through the list and calls vunamp on each one. This is pretty poor: a global TLB flush is generally still performed on each vunmap, with the most expensive parts of the operation being the broadcast IPIs and locking involved in the SMP callouts, and the locking involved in the vmap management -- none of these are avoided by just batching up the calls. I'm actually surprised it ever made much difference. (Now that the lazy vmap allocator is upstream, this description is not quite right, but the vunmap batching still doesn't seem to do much) Rip all this logic out of XFS completely. I will improve vmap performance and scalability directly in subsequent patch.

The make_inode_bad isn't actually nessecary anymore - this was my first attempt at skipping the flushing in xfs_reclaim, but it was still too much as the radix tree removal for and inode that's not in the tree tripped up quite badly. So I use I_NEW here to detect these half setup inodes. Real I_NEW indoes still go through xfs_iput_new.

Hmm, From the syscall point of view fiemap is indeed an ioctl, too. But then again the point of this function isn't do anything ioctl-related, but to allow to get a list of all extents for an inode and format them arbitrarily.

So I use I_NEW here to detect these half setup > inodes. Real I_NEW indoes still go through xfs_iput_new. Hmmmm - I still don't see that as possible. We don't set I_NEW until we are inside xfs_setup_inode(), which occurs after we insert the inode into the radix tree. xfs_setup_inode() also calls unlock_new_inode(), so the I_NEW flag is cleared before it returns, too. So I can't really see how this check in reclaim does anything.... AFAICT, once we've inserted the new inode into the radix tree, we can't get an error before xfs_setup_inode() is called - even in the allocation case. Hence once we're in the radix tree, xfs_iput_new() should be called to cleanup. All the cases that xfs_destroy_inode() handles are before the inode is inserted into the radix tree, so marking the XFS inode XFS_IBAD in xfs_destroy_inode() is probably a much more reliable way to detect immediate destroy cases in the reclaim code than relying on I_NEW......

If this happens at mount time during xlog_alloc_log() we fail to catch the error and oops. Catch the error from xfs_buf_get_noaddr(), and allow other memory allocations to fail and catch those errors too. Report the error to the console and fail the mount with ENOMEM.

I'm getting the impression that for a single-threaded untar workload at least, a small log (5 or 20MB) is actually faster 128MB. I think when the log is small enough relative to the RAID controller's write-back cache, the writes don't have to wait for actual disk. It's (maybe) like having the log on a ramdisk. Battery-backed write caches on RAID controllers make nobarrier safe (right?), so that's what I was using. With a 20MB external log (on an otherwise-idle RAID1, while the filestem is on a RAID6), during a small-file portion of the tar extraction, I saw log write speeds of over 100MB/s (average over 10s, with dstat, which is like iostat) 1 second peaks of 115MB/s. The disk's max sequential write is more like 80MB/s, which is the peak I was seeing with a 128MB log. The only workload I'm testing with varying log sizes is untarring /home onto a fresh filesystem, so single-threaded creation of 121744 files totalling 12.1GB. There were a few very large directories (10000 files) of mostly small files (25% < 512B, 50% < 1.5k, 95% < 32k, 99.5% < 100k)[1]. There are also some large files on the FS (maybe an ISO image or something). Watching disk throughput during the untar, there is a log-bound portion and a large-file portion that hardly has any log I/O. (The tar was compressed with lzop to 6.9GB, and read over gigE NFS. I primed the cache so there is no NFS traffic for about the first half of the test, and it's never read-limited. Max NFS read speed is > 100MB/s, and I never saw more than 50MB/s during the untar. (NFS server is one of the 16GB-RAM compute nodes, so easily caching the whole file for when the writes evict some of the tar.lzo from the cache on the master node.) Highest user-time CPU usage is about half of a single CPU, system time never hit a full CPU either, so those weren't limiting factors. untar times: 110s w/ a 128MB internal log (note that the max sequential write is at least ~3x higher for the RAID6 the internal log is on) 116s w/ a 128MB external log 113s with a 96MB external log 110s with a 64MB external log 115s with a 20MB external log 110s with a 5MB external log (although IIRC I did see 105s with a 5 or 20MB external log. Sorry, wasn't recording all the timings I did, since I wasn't planning to post... Also, sometimes I was seeing 130s times with the 128MB external log, but maybe that was before I was so consistent with my method for priming the cache, so it was being read-limited... Now I cat twice to /dev/null, then dd bs=1024k count=3200 to /dev/null to make sure the first half of the file really wants to stay in the cache.) I'm thinking of creating the FS with a 96MB external log, but I haven't tested with parallel workloads with logs < 128MB. This RAID array also holds /home (on the first 650GB of array), while this FS (/data) is the last 2.2TB. /home uses an internal log, so if someone's keeping /home busy and someone else is keeping /data busy, their logs won't both be going to the RAID6. (I also use agcount=8 on /data, agcount=7 on /home. Although I/O will probably be bursty, and not loading /home and /data at the same time, my main concern is to avoid scattering files in too many places. fewer AGs = more locality for a bunch of sequentially created files, right? I have 8 spindles in the RAID, so that seemed like a good amount of AGs. RAID6 doesn't like small scattered writes _at_ _all_.) Basically, I really want to ask if my mkfs parameters look good before I let users start filling up the filesystems and running jobs on the cluster, making it hard to redo the mkfs. Am I doing anything that looks silly? mkfs: (from xfsprogs 2.10.1 patches with the sw+agcount usability fix) mkfs.xfs -i attr=2 -d su=64k,sw=6,agcount=8 -n size=16k /dev/sdb2 -L data \ -l lazy-count=1,logdev=/dev/raid1/data-xfslog,size=$((1024*1024*96)) meta-data=/dev/sdb2 isize=256 agcount=8, agsize=70172688 blks = sectsz=512 attr=2 data = bsize=4096 blocks=561381403, imaxpct=5 = sunit=16 swidth=96 blks naming =version 2 bsize=16384 ascii-ci=0 log =/dev/raid1/data-xfslog bsize=4096 blocks=24576, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 mount -o noatime,usrquota,nobarrier,inode64,largeio,swalloc,logbsize=256k,logdev=/dev/raid1/data-xfslog noikeep is the default, since I don't use dmapi, otherwise I would include it, too. And yes, the XFS log is on LVM, near the start of the disk. BTW, is there a way to mount the root filesystem with inode64? If I put that in my fstab, it only tries to do it with a remount (which doesn't work), because I guess Ubuntu's initrd doesn't have mount options from /etc/fstab. I made my root fs 10GB, and with imaxpct=8, so the 32bit inode allocator should do ok. I found -n size=16k helps with random deletion speed, IIRC. I only use that on the big RAID6 filesystems, not / or /var/tmp, since users won't be making their huge data file directories anywhere else. Bonnie++ ends up with highly fragmented directories (xfs_bmap) after random-order file creation. /dev/sdb1 and /dev/sdb2 both have their starts full-stripe aligned (I used parted, and set unit s (sectors), since my strip width is 768sectors. I used a GPT disklabel, since DOS wraps at 2TB) The hardware is a Dell PERC 6/E on an 8-disk 500GB (Seagate) SATA 7200RPM RAID6 (PERC 6/E = LSI MegaRAID SAS 1078 w/256MB of battery backed cache. It talks to an External box of hard drives (MD1000) over a 4-lane (IIRC) SAS cable.) The computer is a Dell PE1950 (equipped with a single quad core 2GHz Harpertown CPU (12MB cache total), with 8GB of DDR2-667MHz on a 5000X chipset). Linux 2.6.27 (Ubuntu Intrepid server kernel, which uses the deadline scheduler by default. Otherwise running Ubuntu AMD64 Hardy (current stable), but it's new hardware that's better supported by a newer kernel.) The RAID1 (holding the external log) is on a PERC 6/I (similar hardware, but hooked up to the interal SATA backplane in the server, instead of the external MD1000.) I'm not sure if it's a separate card with its own 256MB of cache, or if it shares the 256MB with the RAID6 on the PERC 6/E. (I opened up the case when the machine first arrived (just sight-seeing, of course :), but I don't think I looked carefully enough to rule out there being another RAID controller somewhere...) If it's shared, that would explain why 128MB slows down. Otherwise, I don't know, since 128MB should still fit easily in the 256MB of cache. The RAID1 and RAID6 are both set for adaptive readahead in the controller BIOS, and with a 64kB stripe size on the RAID6. I use blockdev --setra 512 /dev/sda # the internal RAID1 blockdev --setra 8192 /dev/sdb # the RAID6 I don't have time to edit my other benchmark numbers into a presentable format right now (I have lots of bonnie++ single-threaded and parallel results for various XFS parameters), but if anyone wants them, email me and I'll post my notes. [1] This is pretty typical of what phylogenetics (trying to make evolutionary trees based on DNA sequences of current life) grad students and profs do on the cluster: generate output file for combinations of (random subsets of) data sets and parameters. Plus they compile software and extract tar files of source code, etc. Probably we're most likely to be I/O bound when reading, since most number crunching takes a lot of CPU for each output file, but summarizing the data at the end usually involves reading all the output files. But I don't want it to be slow when people untar something, or whatever. The machine is an NFS server (over bonded gigE) for a 650GB /home and a 2.2TB /data both on the same 8-disk RAID6. 12 compute nodes will run jobs that write to those FSes (usually slowly), while interactive users will mostly be local on the master node. The large amount of small files people usually generate is why I didn't go with LUSTRE. It, or PVFS, might still be useful to make a scratch filesystem out of the 500GB disks in each compute node, though. :) Thanks, -- #define X(x,y) x##y Peter Cordes ; e-mail: X(peter@cor , des.ca) "The gods confound the man who first found out how to distinguish the hours!

Ah, OK, I see the problem, though I don't understand why I'm not seeing the might_sleep() triggering all the time given that I always build with: $ grep SLEEP .config CONFIG_DEBUG_SPINLOCK_SLEEP=y Basically the above commit moved xfs_ilock() inside radix_tree_preload()/radix_tree_preload_end(), which means we are taking a rwsem() while we have an elevated preempt count. I'll get a patch out to fix it. The question is why isn't this triggering for me during QA runs?

It will make XFS behave like other filesystems w.r.t. atime, instead of defaulting to relatime-like behaviour. This will have performance impact unless ppl now add the relatime mount option. Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: Implement ->dirty_inode callout Hook up ->dirty_inode so that when the VFS dirties an inode we can mark the XFS inode as "dirty with unlogged changes". This allows events such as touch_atime() to propagate the dirty state right through to XFS so it gets written back to disk.

I've put in some instrumentation and we indeed newer hit the I_NEW case. I also can't reproduce the problems I saw before anymore - in fact calling radix_tree_remove on an inode is explicitly fine per documentation and does work. I'll send a reworked patch that just uses make_inode_bad as this has passed xfsqa a few times now. I've also removed patch 2 for now a it's not a bug fix an I'll put it into my later series that cleans up a lot of mess in that area.

Instead of using xfs_itobp on a fake inode which is complicated and currently leads to leaks of the security data just use xfs_inotobp which is designed to do exactly the kind of lookup xfs_bulkstat wants. The only thing that's missing in xfs_inotobp is a flags paramter that let's us pass down XFS_IMAP_BULKSTAT, but that can easily added.

Right - the preload allows us to do GFP_KERNEL allocations for radix tree nodes and use a spinlock for inserts into the tree. We could drop the preload stuff if we initialised the radix tree to use GFP_ATOMIC allocations for radix tree nodes, but that is more likely to lead to insert failures under low memory conditions compared to the preload method.

Ok. Removed those two casts. Updated patch below. Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: handle memory allocation failures during log initialisation When there is no memory left in the system, xfs_buf_get_noaddr() can fail. If this happens at mount time during xlog_alloc_log() we fail to catch the error and oops. Catch the error from xfs_buf_get_noaddr(), and allow other memory allocations to fail and catch those errors too. Report the error to the console and fail the mount with ENOMEM. Tested by manually injecting errors into xfs_buf_get_noaddr() and xlog_alloc_log().

[snip lots of stuff] Basically it comes down to the fact that the default (internal 128MB log) is pretty much the fastest option when you have a battery backed cache, right? > untar times: > 110s w/ a 128MB internal log (note that the max sequential write is > at least ~3x higher for the RAID6 the internal log is on) > 116s w/ a 128MB external log > 113s with a 96MB external log > 110s with a 64MB external log > 115s with a 20MB external log > 110s with a 5MB external log In general, a small log is going to limit your transaction parallelism. You are running a single threaded workload, so that's not a big deal. Note that with a 16k directory block size, the transaction reservation sizes are in the order of 3MB, which means that with a 5MB log you'll completely serialise directory modifications. IOWs, don't do it. Larger logs are better because they allow many transactions to be executed in parallel - something that happens alot on a fileserver. Also, large logs allow writeback of metadata to be avoided when it is frequently modified and relogged. Metadata writeback is typically a small random write pattern.... > I'm thinking of creating the FS with a 96MB external log, but I > haven't tested with parallel workloads with logs < 128MB.

That's pretty much irrelevant if you have a couple hundred MB of write cache - the write cache will buffer each sequential log I/O stream until they span full RAID stripes and then it will sync them to disk as efficiently as possible. That's why the 128MB internal log performs so well...... > (I also use agcount=8 on > /data, agcount=7 on /home.

That is, only one allocation or free can be taking place in an AG at once. If you have lots of threads banging on the filesystem, you need enough AGs to prevent modifcation of the free space trees being the bottleneck. The data in each AG will be packed as tightly as possible.... BTW, there is no real correlation between spindle count and # of AGs for stripe based volumes as all AGs span all spindles. If you have a linear concatenation, then you have the case where the number of AGs should match or be a multiple of the number of spindles. The allows AGs to operate completely independently of each other.... > Basically, I really want to ask if my mkfs parameters look good > before I let users start filling up the filesystems and running jobs > on the cluster, making it hard to redo the mkfs.

You probably missed the context of that patch (which I mentioned on IRC to Tim). That was that it is part of a larger patch set that tracks dirty state in the XFS inode radix tree. In that case, the ->dirty_inode callout is used to set a tag in the per-ag inode radix tree. I want to do it this way so there is a single place that the dirty tag is set, whether it is due to an unlogged change (XFS or VFS) or a transaction commit.... Also, if you read the referenced thread, Christoph made the comment that the VFS was not letting us know that the inode had been dirtied and that we really needed to know about that. The patch I sent isn't intended to do this, not as a fix for atime updates... > Why not only do: > > From 96be907a11f2cad0d6c8696737bb144b1275ce5a Mon Sep 17 00:00:00 2001 > From: Niv Sardi > Date: Thu, 23 Oct 2008 13:41:09 +1100 > Subject: [PATCH] Mark core as dirty when atime updated needed for XFS inode > > Currently we're not writting atime updates back to disk on unmount > if it's the only change that happened.

Think about it - you traverse a million inodes stat()ing them all (the nightly backup). Instead of having the now dirty inodes written back as you go along, you wait until memory reclaim turfs them out to mark them dirty and then write them back. This means memory reclaim goes *much slower* because reclaiming the memory now has to wait for I/O to complete. The speed of inode reclaim is already a problem when we only have clean inodes. If we now have to write back all these inodes, we'll get at best a couple of thousand inodes cleaned a second (with current writeback algorithms) and it could be as little as 50 inodes/s when software RAID5 on SATA disks is involved. That means reclaim will be very slow, as will unmount. This could make low memory situations effectively unrecoverable when the inode caches dominate memory usage (e.g. your build servers after the nightly backup has run).

I am using gentoo and I share a portage tree mounted on an xfs filesystem via NFS. Each time packages are fetched, the emerge process is blocked. It seems the problematic commit is the following: commit c068663ae65e507814545b59a8e2090f48a85613 Author: Christoph Hellwig Date: Sun Oct 12 14:30:44 2008 +0200 xfs: fix remount rw with unrecognized options commit 6c5e51dae2c37127e00be392f40842e08077e96a upstream When we skip unrecognized options in xfs_fs_remount we should just break out of the switch and not return because otherwise we may skip clearing the xfs-internal read-only flag. This will only show up on some operations like touch because most read-only checks are done by the VFS which thinks this filesystem is r/w. Eventually we should replace the XFS read-only flag with a helper that always checks the VFS flag to make sure they can never get out of sync. Bug reported and fix verified by Marcel Beister on #xfs. Bug fix verified by updated xfstests/189. If I revert it, the problem doesn't occur.

Actually, it was put there for a reason. The generic code doesn't allow new inodes to be found in the cache until the I_LOCK flag is cleared. This is done by calling wait_on_inode() after a successful lookup (which waits on I_LOCK) and unlock_new_inode() clears the I_LOCK|I_NEW bits and wakes anyone who was waiting on that inode via wake_up_inode(). So the assert was put there to catch potential races in lookup where a second process does a successful igrab() before the inode is fully initialised. I think the race is in dealing with cache hits and recycling a XFS_IRECLAIMABLE inode. We set the XFS_INEW flag there under the radix tree read lock, which means we can have parallel lookups on the same inode that goes: thread 1 thread 2 test XFS_INEW -> not set test XFS_IRECLAIMABLE -> set test XFS_INEW -> not set set XFS_INEW clear XFS_IRECLAIMABLE test XFS_IRECLAIMABLE -> not set xfs_setup_inode() -> i_state = I_NEW|I_LOCK igrab(inode) -> I_CLEAR not set -> refcount = 2 -> inode_add_to_lists -> assert(refcount == 1) ..... -> clear XFS_INEW -> unlock_new_inode() -> clear I_NEW|I_LOCK I thought I'd handled this race with the ordering of setting/clearing XFS_INEW/XFS_IRECLAIMABLE. Clearly not. I'll add a comment to this ordering because it is key to actually detecting the race condition so we can handle it. Hmmmm - there's also another bug in xfs_iget_cache_hit() - we don't drop the reference we got if we found an unlinked inode after the igrab() (the ENOENT case). I'll fix that as well. Patch below that I'm currently running through xfsqa. Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: Fix race when looking up reclaimable inodes If we get a race looking up a reclaimable inode, we can end up with the winner proceeding to use the inode before it has been completely re-initialised. This is a Bad Thing. Fix the race by checking whether we are still initialising the inod eonce we have a reference to it, and if so wait for the initialisation to complete before continuing. While there, fix a leaked reference count in the same code when encountering an unlinked inode and we are not doing a lookup for a create operation. --- fs/xfs/linux-2.6/xfs_linux.h | 1 + fs/xfs/xfs_iget.c | 32 ++++++++++++++++++++++---------- 2 files changed, 23 insertions(+), 10 deletions(-) diff --git a/fs/xfs/linux-2.6/xfs_linux.h b/fs/xfs/linux-2.6/xfs_linux.h index cc0f7b3..947dfa1 100644 --- a/fs/xfs/linux-2.6/xfs_linux.h +++ b/fs/xfs/linux-2.6/xfs_linux.h @@ -77,6 +77,7 @@ #include #include #include +#include #include #include diff --git a/fs/xfs/xfs_iget.c b/fs/xfs/xfs_iget.c index 837cae7..bf4dc5e 100644 --- a/fs/xfs/xfs_iget.c +++ b/fs/xfs/xfs_iget.c @@ -52,7 +52,7 @@ xfs_iget_cache_hit( int lock_flags) __releases(pag->pag_ici_lock) { struct xfs_mount *mp = ip->i_mount; - int error = 0; + int error = EAGAIN; /* * If INEW is set this inode is being set up @@ -60,7 +60,6 @@ xfs_iget_cache_hit( * Pause and try again. */ if (xfs_iflags_test(ip, (XFS_INEW|XFS_IRECLAIM))) { - error = EAGAIN; XFS_STATS_INC(xs_ig_frecycle); goto out_error; } @@ -73,7 +72,6 @@ xfs_iget_cache_hit( * error immediately so we don't remove it from the reclaim * list and potentially leak the inode. */ - if ((ip->i_d.di_mode == 0) && !(flags & XFS_IGET_CREATE)) { error = ENOENT; goto out_error; @@ -91,27 +89,42 @@ xfs_iget_cache_hit( error = ENOMEM; goto out_error; } + + /* + * We must set the XFS_INEW flag before clearing the + * XFS_IRECLAIMABLE flag so that if a racing lookup does + * not find the XFS_IRECLAIMABLE above but has the igrab() + * below succeed we can safely check XFS_INEW to detect + * that this inode is still being initialised. + */ xfs_iflags_set(ip, XFS_INEW); xfs_iflags_clear(ip, XFS_IRECLAIMABLE); /* clear the radix tree reclaim flag as well. */ __xfs_inode_clear_reclaim_tag(mp, pag, ip); - read_unlock(&pag->pag_ici_lock); } else if (!igrab(VFS_I(ip))) { /* If the VFS inode is being torn down, pause and try again. */ - error = EAGAIN; XFS_STATS_INC(xs_ig_frecycle); goto out_error; - } else { - /* we've got a live one */ - read_unlock(&pag->pag_ici_lock); + } else if (xfs_iflags_test(ip, XFS_INEW)) { + /* + * We are racing with another cache hit that is + * currently recycling this inode out of the XFS_IRECLAIMABLE + * state.

The idea is to build the XFS dev branch nightly, run a bunch of self contained benchmarks, and generate a progressive daily report - date on the X-axis, with (perhaps) wallclock runtime on the y-axis. The aim is to track relative XFS performance on a daily basis for various workloads on identical h/w. If each workload runs for approx the same duration, the reports can all share the same generic y-axis. THe long term trend should have a positive gradient. Regressions can be date correlated with commits. Comments, benchmark suggestions? ANyone already running this? Know of a test harness and/or report generator? Or will we just roll our own - seems conceptually fairly simple.

The formatter takes info for 1 extent, a pointer to the user "thing*" and a pointer to a "filled" variable to indicate whether a userspace buffer did get filled in (for fiemap, hole "extents" are skipped). I'm just using the getbmapx struct as a "common denominator" because as far as I can see, it holds all info that any formatters will care about. ("*thing" because fiemap doesn't pass the user pointer around, but rather has a pointer to a fiemap info structure, and helpers associated with it) Signed-off-by: Eric Sandeen --- linux-2.6/xfs_ioctl.c | 39 ++++++++---------------- xfs_bmap.c | 81 +++++++++++++++++++++++++++----------------------- xfs_bmap.h | 13 +++++--- xfs_fs.h | 12 ------- 4 files changed, 67 insertions(+), 78 deletions(-) Index: linux-2.6.27.x86_64/fs/xfs/xfs_bmap.c =================================================================== --- linux-2.6.27.x86_64.orig/fs/xfs/xfs_bmap.c +++ linux-2.6.27.x86_64/fs/xfs/xfs_bmap.c @@ -5742,9 +5742,9 @@ error0: STATIC int xfs_getbmapx_fix_eof_hole( xfs_inode_t *ip, /* xfs incore inode pointer */ - struct getbmap *out, /* output structure */ + struct getbmapx *out, /* output structure */ int prealloced, /* this is a file with - * preallocated data space */ + * preallocated data space */ __int64_t end, /* last block requested */ xfs_fsblock_t startblock) { @@ -5769,15 +5769,38 @@ xfs_getbmapx_fix_eof_hole( return 1; } +int xfs_getbmapx_format(void __user **ap, struct getbmapx *bmv, int *filled) +{ + *filled = 0; + if (copy_to_user(*ap, bmv, sizeof(struct getbmapx))) + return XFS_ERROR(EFAULT); + + *ap += sizeof(struct getbmapx); + *filled = 1; + return 0; +} + +int xfs_getbmap_format(void __user **ap, struct getbmapx *bmv, int *filled) +{ + *filled = 0; + /* copy only getbmap portion (not getbmapx) */ + if (copy_to_user(ap, bmv, sizeof(struct getbmap))) + return XFS_ERROR(EFAULT); + + *ap += sizeof(struct getbmap); + *filled = 1; + return 0; +} + /* - * Fcntl interface to xfs_bmapi. + * Get inode's extents as described in bmv, and format for output. */ int /* error code */ xfs_getbmap( xfs_inode_t *ip, - struct getbmap *bmv, /* user bmap structure */ - void __user *ap, /* pointer to user's array */ - int interface) /* interface flags */ + struct getbmapx *bmv, /* user bmap structure */ + xfs_bmap_format_t formatter, /* format to user */ + void *arg) /* formatter arg (user ptr etc) */ { __int64_t bmvend; /* last block requested */ int error; /* return value */ @@ -5790,19 +5813,20 @@ xfs_getbmap( int nexleft; /* # of user extents left */ int subnex; /* # of bmapi's can do */ int nmap; /* number of map entries */ - struct getbmap out; /* output structure */ + struct getbmapx out; /* output structure */ int whichfork; /* data or attr fork */ int prealloced; /* this is a file with * preallocated data space */ int sh_unwritten; /* true, if unwritten */ /* extents listed separately */ + int iflags; /* interface flags */ int bmapi_flags; /* flags for xfs_bmapi */ - __int32_t oflags; /* getbmapx bmv_oflags field */ mp = ip->i_mount; + iflags = bmv->bmv_iflags; - whichfork = interface & BMV_IF_ATTRFORK ?

This simply adds the fiemap inode_operation, which for us converts the fiemap values & flags into a getbmapx structure which can be sent to xfs_getbmap. The formatter then copies the bmv array back into the user's fiemap buffer. This does *not* yet do delalloc; it still syncs the file just as xfs_bmap always did. That will come later; I'd like to get the basic hookup out for review & committed so that we have something for 2.6.28. This adds another output flag, BMV_OF_LAST to indicate if we've hit the last extent in the inode. This potentially saves an extra call from userspace to see when the whole mapping is done. If we wanted to be clever-er, we could also return mapping data for in-inode attributes, but I'm not terribly motivated to do that just yet. :) Signed-off-by: Eric Sandeen --- Index: linux-2.6.27.x86_64/fs/xfs/linux-2.6/xfs_iops.c =================================================================== --- linux-2.6.27.x86_64.orig/fs/xfs/linux-2.6/xfs_iops.c +++ linux-2.6.27.x86_64/fs/xfs/linux-2.6/xfs_iops.c @@ -53,6 +53,7 @@ #include #include #include +#include /* * Bring the atime in the XFS inode uptodate. @@ -661,6 +662,74 @@ out_error: return error; } +#define XFS_FIEMAP_FLAGS (FIEMAP_FLAG_SYNC|FIEMAP_FLAG_XATTR) + +STATIC int xfs_fiemap_format( + void **arg, + struct getbmapx *bmv, + int *filled) +{ + int error = 0; + struct fiemap_extent_info *fieinfo= *arg; + u32 fiemap_flags = 0; + u64 logical, physical, length; + + *filled = 0; + /* Do nothing for a hole */ + if (bmv->bmv_block == -1LL) + return 0; + + logical = BBTOB(bmv->bmv_offset); + physical = BBTOB(bmv->bmv_block); + length = BBTOB(bmv->bmv_length); + + if (bmv->bmv_oflags & BMV_OF_PREALLOC) + fiemap_flags |= FIEMAP_EXTENT_UNWRITTEN; + if (bmv->bmv_oflags & BMV_OF_LAST) + fiemap_flags |= FIEMAP_EXTENT_LAST; + + error = fiemap_fill_next_extent(fieinfo, logical, physical, + length, fiemap_flags); + if (error < 0) + return -error; + *filled = 1; + return 0; +} + +STATIC int +xfs_vn_fiemap( + struct inode *inode, + struct fiemap_extent_info *fieinfo, + u64 start, + u64 length) +{ + xfs_inode_t *ip = XFS_I(inode); + struct getbmapx bm; + int error; + + if (fiemap_check_flags(fieinfo, XFS_FIEMAP_FLAGS)) + return -EBADR; + + /* Set up bmap header for xfs internal routine */ + bm.bmv_offset = BTOBB(start); + /* Special case for whole file */ + if (length == FIEMAP_MAX_OFFSET) + bm.bmv_length = -1LL; + else + bm.bmv_length = BTOBB(length); + /* xfs_getbmap takes count as header + array */ + bm.bmv_count = fieinfo->fi_extents_max + 1; + bm.bmv_iflags = BMV_IF_PREALLOC; + if (fieinfo->fi_flags & FIEMAP_FLAG_XATTR) + bm.bmv_iflags |= BMV_IF_ATTRFORK; + + error = xfs_getbmap(ip, &bm, xfs_fiemap_format, fieinfo); + if (error) + return -XFS_ERROR(error); + + return 0; +} + static const struct inode_operations xfs_inode_operations = { .permission = xfs_vn_permission, .truncate = xfs_vn_truncate, @@ -671,6 +740,7 @@ static const struct inode_operations xfs .removexattr = generic_removexattr, .listxattr = xfs_vn_listxattr, .fallocate = xfs_vn_fallocate, + .fiemap = xfs_vn_fiemap, }; static const struct inode_operations xfs_dir_inode_operations = { Index: linux-2.6.27.x86_64/fs/xfs/xfs_bmap.c =================================================================== --- linux-2.6.27.x86_64.orig/fs/xfs/xfs_bmap.c +++ linux-2.6.27.x86_64/fs/xfs/xfs_bmap.c @@ -5750,6 +5750,9 @@ xfs_getbmapx_fix_eof_hole( { __int64_t fixlen; xfs_mount_t *mp; /* file system mount point */ + xfs_ifork_t *ifp; /* inode fork pointer */ + xfs_extnum_t lastx; /* last extent pointer */ + xfs_fileoff_t fileblock; /* logical mapping offset */ if (startblock == HOLESTARTBLOCK) { mp = ip->i_mount; @@ -5764,6 +5767,11 @@ xfs_getbmapx_fix_eof_hole( } } else { out->bmv_block = XFS_FSB_TO_DB(ip, startblock); + fileblock = XFS_BB_TO_FSB(ip->i_mount, out->bmv_offset); + ifp = XFS_IFORK_PTR(ip, XFS_DATA_FORK); + if (xfs_iext_bno_to_ext(ifp, fileblock, &lastx) && + (lastx == (ifp->if_bytes / (uint)sizeof(xfs_bmbt_rec_t)) - 1)) + out->bmv_oflags |= BMV_OF_LAST; } return 1; @@ -5957,6 +5965,7 @@ xfs_getbmap( if (map[i].br_startblock == HOLESTARTBLOCK && whichfork == XFS_ATTR_FORK) { /* came to the end of attribute fork */ + out.bmv_oflags |= BMV_OF_LAST; goto unlock_and_return; } else { int filled; /* extents filled by formatter */ Index: linux-2.6.27.x86_64/fs/xfs/xfs_fs.h =================================================================== --- linux-2.6.27.x86_64.orig/fs/xfs/xfs_fs.h +++ linux-2.6.27.x86_64/fs/xfs/xfs_fs.h @@ -117,6 +117,7 @@ struct getbmapx { /* bmv_oflags values - returned for for each non-header segment */ #define BMV_OF_PREALLOC 0x1 /* segment = unwritten pre-allocation */ +#define BMV_OF_LAST 0x4 /* segment is the last in the file */ /* * Structure for XFS_IOC_FSSETDM.

The usual set - bonnie++, postmark, ffsb, fio, sio, etc. Then some artificial tests that stress scalability like speed of creating 1m small files with long names in a directory, the speed of a cold cache read of the directory, the speed of a hot-cache read of the directory, time to stat all the files (cold and hot cache), time to remove all the files, etc. And then how well it scales as you do this with more threads and directories in parallel... > ANyone already running this? > Know of a test harness and/or report generator? Perhap you might want to look more closely at FFSB - it has a fairly interesting automated test harness. e.g. it was used to produce these: http://btrfs.boxacle.net/ And you can probably set up custom workloads to cover all the things that the standard benchmarks do.....

Does it go away when you add the "XFS: Fix race when looking up reclaimable inodes" I sent this morning? Also, is there a thread stuck in xfs_setfilesize() waiting on an ilock during I/O completion? i.e. did the log hang because I/O completion is stuck waiting on an ilock that is held by a thread waiting on I/O completion?

Checking for (iflags & BMV_IF_DELALLOC) is fine by me, same for replacing sh_unwritten. I've never really liked the "sh" abbreviation for "show".... Otherwise it looks ok.

So, to refrase, you have a patchset, that will use that callback better, and then we will not need the patch you actually sent ? why not wait for that patchset, this is not exactly a critical bug

I'm concerned about the overhead, with your patch, that we'll be writting things even if nothing has changed, not sure about how many times ->dirty_inodes is called and such. I don't like the idea to slow things down for everyone or force people to use realtime Cheers, -- Niv Sardi From owner-xfs@oss.sgi.com Thu Oct 23 23:08:13 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.5 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.168.29]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9O68BfJ011108 for ; Thu, 23 Oct 2008 23:08:13 -0700 X-ASG-Debug-ID: 1224828490-1add03830000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from ipmail01.adl6.internode.on.net (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 81D19538780 for ; Thu, 23 Oct 2008 23:08:10 -0700 (PDT) Received: from ipmail01.adl6.internode.on.net (ipmail01.adl6.internode.on.net [203.16.214.146]) by cuda.sgi.com with ESMTP id G39SoEeukCGtC8Ly for ; Thu, 23 Oct 2008 23:08:10 -0700 (PDT) X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: Am4DAM8S9kh5LE2tgWdsb2JhbACTYAEBFiKuDIFr X-IronPort-AV: E=Sophos;i="4.33,475,1220193000"; d="scan'208";a="217307034" Received: from ppp121-44-77-173.lns10.syd6.internode.on.net (HELO disturbed) ([121.44.77.173]) by ipmail01.adl6.internode.on.net with ESMTP; 24 Oct 2008 16:38:08 +1030 Received: from dave by disturbed with local (Exim 4.69) (envelope-from ) id 1KtFqA-0002S5-Vn; Fri, 24 Oct 2008 17:08:06 +1100 Date: Fri, 24 Oct 2008 17:08:06 +1100 From: Dave Chinner To: Niv Sardi Cc: Utako Kusaka , Timothy Shimmin , xfs X-ASG-Orig-Subj: Re: [PATCH, RFC] Re: atime not written to disk Subject: Re: [PATCH, RFC] Re: atime not written to disk Message-ID: <20081024060806.GJ18495@disturbed> Mail-Followup-To: Niv Sardi , Utako Kusaka , Timothy Shimmin , xfs References: <48FD74CC.907@sgi.com> <48FD7B69.3090600@wm.jp.nec.com> <20081022081710.GL18495@disturbed> <20081023042053.GY18495@disturbed> MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Disposition: inline Content-Transfer-Encoding: 8bit In-Reply-To: User-Agent: Mutt/1.5.18 (2008-05-17) X-Barracuda-Connect: ipmail01.adl6.internode.on.net[203.16.214.146] X-Barracuda-Start-Time: 1224828491 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: -1.42 X-Barracuda-Spam-Status: No, SCORE=-1.42 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests=COMMA_SUBJECT X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.8625 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.60 COMMA_SUBJECT Subject is like 'Re: FDSDS, this is a subject' On Fri, Oct 24, 2008 at 04:37:59PM +1100, Niv Sardi wrote: > Dave Chinner writes: > > > On Thu, Oct 23, 2008 at 01:53:23PM +1100, Niv Sardi wrote: > >> Dave Chinner writes: > >> [...] > >> > As I mentioned on IRC, Tim, the following patch fixes the above test > >> > case.

 No, that patch is part of the patchset. In fact - it's the first patch in the patchset of 4 patches. The following patches are: xfs-iradix-set-dirty-tag xfs-iradix-use-dirty-tag-for-clustering xfs-iradix-use-dirty-tag-for-sync i.e. using the radix tree for finding sequential dirty inode clusters for writeback.... It's not complete yet, because I'm trying to decide if it is better to avoid inode writeback from ->write_inode altogether and only do optimised ascending order inode writeback from from xfs_sync_inodes() and/or AIL tail pushing.... > >> Why not only do: > [

The VFS calling mark_inode_dirty_sync() is not "nothing". > times ->dirty_inodes is called and such. I don't like the idea to slow > things down for everyone or force people to use realtime I didn't suggest we force ppl to use relatime - I suggested that we default to it behind the covers and then pay attention to all dirty events coming form the VFS. This should result in practically no increase in the number of atime-only inode writes....

I want to keep this really simple, just provide high level tracking on *when* a performance regression may have been introduced but only with broad indicators.

I would regard that as follow-up once an issue has been identified. My proposal is too simple to be useful for diagnosis, but it should be enough to provide heads-up. That's the aim to start with. The same h/w can also be set up for more sophisticated measurements in the longer term. >> Comments, benchmark suggestions? > > The usual set - bonnie++, postmark, ffsb, fio, sio, etc. > > Then some artificial tests that stress scalability like speed of > creating 1m small files with long names in a directory, the speed of > a cold cache read of the directory, the speed of a hot-cache read of > the directory, time to stat all the files (cold and hot cache), > time to remove all the files, etc. And then how well it scales > as you do this with more threads and directories in parallel... yeah OK, bits and pieces of the the above, enough to provide broad heads-up. >> ANyone already running this? >> Know of a test harness and/or report generator? > > Perhap you might want to look more closely at FFSB - it has a > fairly interesting automated test harness. e.g. it was used to > produce these: > > http://btrfs.boxacle.net/ > > And you can probably set up custom workloads to cover all the things > that the standard benchmarks do.....

("*thing" because fiemap doesn't pass the user pointer around, but rather has a pointer to a fiemap info structure, and helpers associated with it) Signed-off-by: Eric Sandeen --- Index: linux-2.6-xfs/fs/xfs/xfs_bmap.c =================================================================== --- linux-2.6-xfs.orig/fs/xfs/xfs_bmap.c +++ linux-2.6-xfs/fs/xfs/xfs_bmap.c @@ -5805,9 +5805,9 @@ error0: STATIC int xfs_getbmapx_fix_eof_hole( xfs_inode_t *ip, /* xfs incore inode pointer */ - struct getbmap *out, /* output structure */ + struct getbmapx *out, /* output structure */ int prealloced, /* this is a file with - * preallocated data space */ + * preallocated data space */ __int64_t end, /* last block requested */ xfs_fsblock_t startblock) { @@ -5832,15 +5832,38 @@ xfs_getbmapx_fix_eof_hole( return 1; } +int xfs_getbmapx_format(void __user **ap, struct getbmapx *bmv, int *filled) +{ + *filled = 0; + if (copy_to_user(*ap, bmv, sizeof(struct getbmapx))) + return XFS_ERROR(EFAULT); + + *ap += sizeof(struct getbmapx); + *filled = 1; + return 0; +} + +int xfs_getbmap_format(void __user **ap, struct getbmapx *bmv, int *filled) +{ + *filled = 0; + /* copy only getbmap portion (not getbmapx) */ + if (copy_to_user(*ap, bmv, sizeof(struct getbmap))) + return XFS_ERROR(EFAULT); + + *ap += sizeof(struct getbmap); + *filled = 1; + return 0; +} + /* - * Fcntl interface to xfs_bmapi. + * Get inode's extents as described in bmv, and format for output. */ int /* error code */ xfs_getbmap( xfs_inode_t *ip, - struct getbmap *bmv, /* user bmap structure */ - void __user *ap, /* pointer to user's array */ - int interface) /* interface flags */ + struct getbmapx *bmv, /* user bmap structure */ + xfs_bmap_format_t formatter, /* format to user */ + void *arg) /* formatter arg */ { __int64_t bmvend; /* last block requested */ int error; /* return value */ @@ -5853,19 +5876,20 @@ xfs_getbmap( int nexleft; /* # of user extents left */ int subnex; /* # of bmapi's can do */ int nmap; /* number of map entries */ - struct getbmap out; /* output structure */ + struct getbmapx out; /* output structure */ int whichfork; /* data or attr fork */ int prealloced; /* this is a file with * preallocated data space */ int sh_unwritten; /* true, if unwritten */ /* extents listed separately */ + int iflags; /* interface flags */ int bmapi_flags; /* flags for xfs_bmapi */ - __int32_t oflags; /* getbmapx bmv_oflags field */ mp = ip->i_mount; + iflags = bmv->bmv_iflags; - whichfork = interface & BMV_IF_ATTRFORK ?

This adds the fiemap inode_operation, which for us converts the fiemap values & flags into a getbmapx structure which can be sent to xfs_getbmap. The formatter then copies the bmv array back into the user's fiemap buffer via the fiemap helpers. This adds a new output flag, BMV_OF_LAST to indicate if we've hit the last extent in the inode. This potentially saves an extra call from userspace to see when the whole mapping is done. It also adds BMV_IF_DELALLOC and BMV_OF_DELALLOC to request, and indicate, delayed-allocation extents. If we wanted to be more clever, we could also return mapping data for in-inode attributes, but I'm not terribly motivated to do that just yet.

You declare the first argument to the filler as __user pointer here, but without it in the fiemap version. I think the better interface would be to pass a void *buffer, which is casted to a struct { struct getbmap(x) __user *base, unsigned nr; } for the XFS ioctl case and something different for fiemap. And please run sparse over it :) Except for that the patch looks good to me.

Nasty. My initial though is to make _xfs_trans_alloc() able to take a KM_NOFS argument so we don't re-enter the FS here. If we get an ENOMEM in this case, we should then re-queue the I/O completion at the back of the workqueue and let other I/o completions progress before retrying this one. That way the I/O that is simply cleaning memory will make progress, hence allowing memory allocation to occur successfully when we retry this I/O completion... XFS-folk - thoughts? [1] I don't see how any of the XFS changes we made make this easier to hit. What I suspect is a VM regression w.r.t. memory reclaim because this is the second problem since 2.6.26 that appears to be a result of memory allocation failures in places that we've never, ever seen failures before. The other new failure is this one: http://bugzilla.kernel.org/show_bug.cgi?id=11805 which is an alloc_pages(GFP_KERNEL) failure.... mm-folk - care to weight in?

Because it is sleeping in I/O completion, the log tail can't move forward because I/O completion is not occurring. I think that at this point, we need a separate workqueue for unwritten extent conversion to prevent it from blocking normal data and metadata I/O completion. that way we can allow it to recurse on allocation and transaction reservation without introducing I/O completion deadlocks....

IMHO it *should* probably be up to the fs to handle the sync flag.

As far as the kernel and most userspace is concerned this works perfectly, but applications still using really old stat and readdir interfaces will get an EOVERFLOW error when hitting an inode number not fitting into 32 bits (that problem of course also exists when using these applications on a 64bit kernel). Note that because inode64 is simply a mount option we can currently mount a filesystem having > 32 bit inode numbers and cause a variety of problems, all this is solved but this patch which enables XFS_BIG_INUMS, even when inode64 is not used.

All sizeof operations on the dinode_core either really wanted the icdinode and are switched to that one, or had already added the size of the agi unlinked list pointer. Later both will be replaced with helpers once we get the larger CRC-enabled dinode. Removing the data and attribute fork unions also has the advantage that xfs_dinode.h doesn't need to pull in every header under the sun. While we're at it also add some more comments describing the dinode structure.

This adds a new output flag, BMV_OF_LAST to indicate if we've hit the last extent in the inode. This potentially saves an extra call from userspace to see when the whole mapping is done. It also adds BMV_IF_DELALLOC and BMV_OF_DELALLOC to request, and indicate, delayed-allocation extents. In this case bmv_block is set to -2 (-1 was already taken for HOLESTARTBLOCK; unfortunately these are the reverse of the in-kernel constants.) These new flags facilitate addition of the new fiemap interface. Rather than adding sh_delalloc, remove sh_unwritten & just test the flags directly.

The patch below has been running for 15 minutes now on my UML box that would have hung in a couple of minutes otherwise. FYI, the way I found this was: - put a breakpoint on xfs_create() once the fs hung - `touch /mnt/xfs2/fred` to trigger the break point. - look at: - mp->m_ail->xa_target - mp->m_ail->xa_ail.next->li_lsn - mp->m_log->l_tail_lsn which indicated the push target was way ahead the tail of the log, so AIL pushing was obviously not happening otherwise we'd be making progress. - added breakpoint on xfsaild_push() and continued - xfsaild_push() bp triggered, looked at *last_lsn and found it way behind the tail of the log (like 3 cycle behind), which meant that would return NULL instead of the first object and AIL pushing would abort. Confirmed with single stepping. Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: correctly select first log item to push Under heavy metadata load we are seeing log hangs. The AIL has items in it ready to be pushed, and they are within the push target window. However, we are not pushing them when the last pushed LSN is less than the LSN of the first log item on the AIL. This is a regression introduced by the AIL push cursor modifications. --- fs/xfs/xfs_trans_ail.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/fs/xfs/xfs_trans_ail.c b/fs/xfs/xfs_trans_ail.c index 67ee466..2d47f10 100644 --- a/fs/xfs/xfs_trans_ail.c +++ b/fs/xfs/xfs_trans_ail.c @@ -228,7 +228,7 @@ xfs_trans_ail_cursor_first( list_for_each_entry(lip, &ailp->xa_ail, li_ail) { if (XFS_LSN_CMP(lip->li_lsn, lsn) >= 0) - break; + goto out; } lip = NULL; out: From owner-xfs@oss.sgi.com Sun Oct 26 18:20:15 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.6 required=5.0 tests=BAYES_00 autolearn=unavailable version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.168.29]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9R1KEmr028740 for ; Sun, 26 Oct 2008 18:20:15 -0700 X-ASG-Debug-ID: 1225070412-7eea02f00000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from ipmail01.adl6.internode.on.net (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 28572549397 for ; Sun, 26 Oct 2008 18:20:13 -0700 (PDT) Received: from ipmail01.adl6.internode.on.net (ipmail01.adl6.internode.on.net [203.16.214.146]) by cuda.sgi.com with ESMTP id I1COHqqokz0VPeyp for ; Sun, 26 Oct 2008 18:20:13 -0700 (PDT) X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: Am4DAM8S9kh5LE2tgWdsb2JhbACTYAEBFiKuDIFr X-IronPort-AV: E=Sophos;i="4.33,489,1220193000"; d="scan'208";a="218715526" Received: from ppp121-44-77-173.lns10.syd6.internode.on.net (HELO disturbed) ([121.44.77.173]) by ipmail01.adl6.internode.on.net with ESMTP; 27 Oct 2008 11:50:11 +1030 Received: from dave by disturbed with local (Exim 4.69) (envelope-from ) id 1KuGm9-0007EZ-NK; Mon, 27 Oct 2008 12:20:09 +1100 Date: Mon, 27 Oct 2008 12:20:08 +1100 From: Dave Chinner To: Christoph Hellwig Cc: xfs@oss.sgi.com X-ASG-Orig-Subj: Re: [PATCH 1/2] wire up ->open for directories Subject: Re: [PATCH 1/2] wire up ->open for directories Message-ID: <20081027012008.GD11948@disturbed> Mail-Followup-To: Christoph Hellwig , xfs@oss.sgi.com References: <20081026203437.GB4173@infradead.org> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20081026203437.GB4173@infradead.org> User-Agent: Mutt/1.5.18 (2008-05-17) X-Barracuda-Connect: ipmail01.adl6.internode.on.net[203.16.214.146] X-Barracuda-Start-Time: 1225070415 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0002 1.0000 -2.0199 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: -2.02 X-Barracuda-Spam-Status: No, SCORE=-2.02 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.8810 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On Sun, Oct 26, 2008 at 04:34:37PM -0400, Christoph Hellwig wrote: > Currently there's no ->open method set for directories on XFS.

The previous code is pretty obviously broken - a search which always returns NULL. Which begs the question on the best way of testing this ail code. I dunno - it would be nice for independent testing of data structures but perhaps that is too ambitious. OOC, so the call path for this code.... xfsaild -> xfsaild_push(ailp, &last_pushed_lsn) -> lip = xfs_trans_ail_cursor_first(ailp, cur, *last_lsn) Initially, last_lsn = 0 in xfsaild but it will be updated via last_pushed_lsn. So it looks like things will work initially when lsn==0, because xfs_trans_ail_cursor_first special cases that and uses the min. But as soon as the lsn is set to non-zero, xfs_trans_ail_cursor_first will return NULL, and xfsaild_push will return early. --Tim From owner-xfs@oss.sgi.com Sun Oct 26 21:08:56 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.5 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-rupdated Received: from relay.sgi.com (relay1.corp.sgi.com [192.26.58.214]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9R48utG007381 for ; Sun, 26 Oct 2008 21:08:56 -0700 Received: from larry.melbourne.sgi.com (larry.melbourne.sgi.com [134.14.52.130]) by relay1.corp.sgi.com (Postfix) with SMTP id 97E4F8F8121 for ; Sun, 26 Oct 2008 21:08:55 -0700 (PDT) Received: from [134.14.55.78] (redback.melbourne.sgi.com [134.14.55.78]) by larry.melbourne.sgi.com (950413.SGI.8.6.12/950213.SGI.AUTOCF) via ESMTP id MAA18910; Mon, 27 Oct 2008 12:43:51 +1100 Message-ID: <49051C71.9040404@sgi.com> Date: Mon, 27 Oct 2008 12:42:09 +1100 From: Lachlan McIlroy Reply-To: lachlan@sgi.com User-Agent: Thunderbird 2.0.0.17 (X11/20080914) MIME-Version: 1.0 To: Lachlan McIlroy , Christoph Hellwig , xfs-oss , linux-mm@kvack.org Subject: Re: deadlock with latest xfs References: <4900412A.2050802@sgi.com> <20081023205727.GA28490@infradead.org> <49013C47.4090601@sgi.com> <20081024052418.GO25906@disturbed> <20081024064804.GQ25906@disturbed> <20081026005351.GK18495@disturbed> <20081026025013.GL18495@disturbed> In-Reply-To: <20081026025013.GL18495@disturbed> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Dave Chinner wrote: > On Sun, Oct 26, 2008 at 11:53:51AM +1100, Dave Chinner wrote: >> On Fri, Oct 24, 2008 at 05:48:04PM +1100, Dave Chinner wrote: >>> OK, I just hung a single-threaded rm -rf after this completed: >>> >>> # fsstress -p 1024 -n 100 -d /mnt/xfs2/fsstress >>> >>> It has hung with this trace: >>> >>> # echo w > /proc/sysrq-trigger >> .... >>> [42954211.590000] 794877f8: [<6002e40a>] update_curr+0x3a/0x50 >>> [42954211.590000] 79487818: [<60014f0d>] _switch_to+0x6d/0xe0 >>> [42954211.590000] 79487858: [<60324b21>] schedule+0x171/0x2c0 >>> [42954211.590000] 794878a8: [<60324e6d>] schedule_timeout+0xad/0xf0 >>> [42954211.590000] 794878c8: [<60326e98>] _spin_unlock_irqrestore+0x18/0x20 >>> [42954211.590000] 79487908: [<60195455>] xlog_grant_log_space+0x245/0x470 >>> [42954211.590000] 79487920: [<60030ba0>] default_wake_function+0x0/0x10 >>> [42954211.590000] 79487978: [<601957a2>] xfs_log_reserve+0x122/0x140 >>> [42954211.590000] 794879c8: [<601a36e7>] xfs_trans_reserve+0x147/0x2e0 >>> [42954211.590000] 794879f8: [<60087374>] kmem_cache_alloc+0x84/0x100 >>> [42954211.590000] 79487a38: [<601ab01f>] xfs_inactive_symlink_rmt+0x9f/0x450 >>> [42954211.590000] 79487a88: [<601ada94>] kmem_zone_zalloc+0x34/0x50 >>> [42954211.590000] 79487aa8: [<601a3a6d>] _xfs_trans_alloc+0x2d/0x70 >> .... >> >> I came back to the system, and found that the hang had gone away - the >> rm -rf had finished sometime in the ~36 hours between triggering the >> problem and coming back to look at the corpse.... >> >> So nothing to report yet. > > Got it now.

It could work - unless it's a synchronous I/O in which case the I/O is not complete until the extent conversion takes place.

Right. Pushing unwritten extent conversion onto a different workqueue is probably the only way to handle this easily. That's the same solution Irix has been using for a long time (the xfsc thread).... > Could we allocate the memory up front before the I/O is issued? Possibly, but that will create more memory pressure than allocation in I/O completion because now we could need to hold thousands of allocations across an I/O - think of the case where we are running low on memory and have a disk subsystem capable of a few hundred thousand I/Os per second. the allocation failing would prevent the I/os from being issued, and if this is buffered writes into unwritten extents we'd be preventing dirty pages from being cleaned....

Right - that was the bug. With the fix we will only return NULL if we walk off the end of the AIL list before we get to the LSN being requested to start at. Otherwise we jump over the "lip = NULL" and start at the first log item with a LSN greater than or equal to the last_lsn....

The allocation has to be done sometime - if have a few hundred thousand I/Os per second then the queue of unwritten extent conversion requests is going to grow very quickly. If a separate workqueue will fix this then that's a better solution anyway.

Sure, but the difference is that in a workqueue we are doing: alloc free alloc free ..... alloc free So the instantaneous memory usage is bound by the number of workqueue threads doing conversions. The "pre-allocate" case is: alloc alloc alloc alloc ...... free ..... free ..... so the allocation is bound by the number of parallel I/Os we have not completed. Given that the transaction structure is *800* bytes, they will consume memory very quickly if pre-allocated before the I/O is dispatched. > If a separate workqueue will fix this > then that's a better solution anyway. I think so. The patch I have been testing is below. Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: Prevent unwritten extent conversion from blocking I/O completion Unwritten extent conversion can recurse back into the filesystem due to memory allocation. Memory reclaim requires I/O completions to be processed to allow the callers to make progress. If the I/O completion workqueue thread is doing the recursion, then we have a deadlock situation. Move unwritten extent completion into it's own workqueue so it doesn't block I/O completions for normal delayed allocation or overwrite data.

It would only really work for synchronous I/O. Even with the current code we could have queues that grow very large because buffered writes to unwritten extents don't wait for the conversion. So even for the small amount of memory we allocate for each queue entry we still could consume a lot in total. > >> If a separate workqueue will fix this >> then that's a better solution anyway. > > I think so. The patch I have been testing is below. Thanks, I'll add it to the list.

Use xfs_bmap to find the location on disk of the extents in each file. Recurse over the filesystem until you find the file that owns the block that went bad.

There is no such thing as a "hole block". It's a sparse file - where there is a hole there are no blocks. i.e. holes are free space.

I've addressed the comment from Shaggy, combined patches that were divided into each filesystems into one patch because of the avoidance of a bisection. Currently, ext3 in mainline Linux doesn't have the freeze feature which suspends write requests. So, we cannot take a backup which keeps the filesystem's consistency with the storage device's features (snapshot and replication) while it is mounted. In many case, a commercial filesystem (e.g. VxFS) has the freeze feature and it would be used to get the consistent backup. If Linux's standard filesystem ext3 has the freeze feature, we can do it without a commercial filesystem. So I have implemented the ioctls of the freeze feature. I think we can take the consistent backup with the following steps. 1. Freeze the filesystem with the freeze ioctl. 2. Separate the replication volume or create the snapshot with the storage device's feature. 3. Unfreeze the filesystem with the unfreeze ioctl. 4. Take the backup from the separated replication volume or the snapshot. [PATCH 1/3] Add error handling of write_super_lockfs and unlockfs VFS: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that they can return an error.

[PATCH 2/3] Implement generic freeze feature The ioctls for the generic freeze feature are below. o Freeze the filesystem int ioctl(int fd, int FIFREEZE, arg) fd: The file descriptor of the mountpoint FIFREEZE: request code for the freeze arg: Ignored Return value: 0 if the operation succeeds. Otherwise, -1 o Unfreeze the filesystem int ioctl(int fd, int FITHAW, arg) fd: The file descriptor of the mountpoint FITHAW: request code for unfreeze arg: Ignored Return value: 0 if the operation succeeds. Otherwise, -1 Error number: If the filesystem has already been unfrozen, errno is set to EINVAL.

As far as the kernel and most userspace is concerned this works perfectly, but applications still using really old stat and readdir interfaces will get an EOVERFLOW error when hitting an inode number not fitting into 32 bits (that problem of course also exists when using these applications on a 64bit kernel). Note that because inode64 is simply a mount option we can currently mount a filesystem having > 32 bit inode numbers and cause a variety of problems, all this is solved but this patch which enables XFS_BIG_INUMS, even when inode64 is not used.

All sizeof operations on the dinode_core either really wanted the icdinode and are switched to that one, or had already added the size of the agi unlinked list pointer. Later both will be replaced with helpers once we get the larger CRC-enabled dinode. Removing the data and attribute fork unions also has the advantage that xfs_dinode.h doesn't need to pull in every header under the sun. While we're at it also add some more comments describing the dinode structure.

I'm not sure what exactly is the difference between free1 and free2 - someone more knowledgable would have to comment (and overally comment about this method).

Ok, just as a follow up: Now we got similar XFS errors on the second backend server, this time on a local hardware RAID1 while on the first backend server it was on logical volumes on a soft RAID spread over two dislocated external hardware RAID boxes. So this appears to be an XFS bug to me. Maybe when running for long time it corrupts its in-memory structures. Fortunately we did not see errors in on-disk structures. A colleague did a kernel update on the inactive backend 1 server from 2.6.21 to 2.6.26 kernel from backports.org, tommorow backend 2 will follow. Let's see whether that solves the issue. Anyway it seems to be a hard to trigger bug and before bugging you with something in kernel 2.6.21, we at least update to the latest backports.org kernel. -- Martin Steigerwald - team(ix) GmbH - http://www.teamix.de gpg: 19E3 8D42 896F D004 08AC A0CA 1E10 C593 0399 AE90 From owner-xfs@oss.sgi.com Mon Oct 27 10:15:23 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.7 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.168.29]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9RHFNbS018277 for ; Mon, 27 Oct 2008 10:15:23 -0700 X-ASG-Debug-ID: 1225127722-313e01730000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mx2.redhat.com (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id DB26D54CFDA; Mon, 27 Oct 2008 10:15:22 -0700 (PDT) Received: from mx2.redhat.com (mx2.redhat.com [66.187.237.31]) by cuda.sgi.com with ESMTP id vdWaHK7Zg7SJGwOL; Mon, 27 Oct 2008 10:15:22 -0700 (PDT) Received: from int-mx2.corp.redhat.com (int-mx2.corp.redhat.com [172.16.27.26]) by mx2.redhat.com (8.13.8/8.13.8) with ESMTP id m9RHFLqE006058; Mon, 27 Oct 2008 13:15:21 -0400 Received: from ns3.rdu.redhat.com (ns3.rdu.redhat.com [10.11.255.199]) by int-mx2.corp.redhat.com (8.13.1/8.13.1) with ESMTP id m9RHFKuT020479; Mon, 27 Oct 2008 13:15:20 -0400 Received: from neon.msp.redhat.com (neon.msp.redhat.com [10.15.80.10]) by ns3.rdu.redhat.com (8.13.8/8.13.8) with ESMTP id m9RHFJk4011569; Mon, 27 Oct 2008 13:15:20 -0400 Message-ID: <4905F727.8030005@sandeen.net> Date: Mon, 27 Oct 2008 12:15:19 -0500 From: Eric Sandeen User-Agent: Thunderbird 2.0.0.16 (X11/20080723) MIME-Version: 1.0 To: Martin Steigerwald CC: Timothy Shimmin , xfs@oss.sgi.com X-ASG-Orig-Subj: Re: Is it possible the check an frozen XFS filesytem to avoid downtime Subject: Re: Is it possible the check an frozen XFS filesytem to avoid downtime References: <200807141542.51613.ms@teamix.de> <200807150944.13277.ms@teamix.de> <487CC1EB.6030100@sandeen.net> <200810271757.09915.ms@teamix.de> In-Reply-To: <200810271757.09915.ms@teamix.de> Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit X-Scanned-By: MIMEDefang 2.58 on 172.16.27.26 X-Barracuda-Connect: mx2.redhat.com[66.187.237.31] X-Barracuda-Start-Time: 1225127722 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: -2.02 X-Barracuda-Spam-Status: No, SCORE=-2.02 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.8853 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- X-Virus-Scanned: ClamAV version 0.91.2, clamav-milter version 0.91.2 on oss.sgi.com X-Virus-Status: Clean Martin Steigerwald wrote: > A colleague did a kernel update on the inactive backend 1 server from 2.6.21 > to 2.6.26 kernel from backports.org, tommorow backend 2 will follow.

The inode modification time of the on-media file is com‐ pared to the inode modification time of corresponding file in the dest directory. The file is restored only if the on-media version is newer than the version in the dest directory. The inode modification time of a file can be displayed with the ls -lc command. --Tim From owner-xfs@oss.sgi.com Mon Oct 27 19:16:58 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.6 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-rupdated Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9S2Gv2p000319 for ; Mon, 27 Oct 2008 19:16:58 -0700 X-ASG-Debug-ID: 1225160215-380203940000-w1Z2WR X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from ciao.gmane.org (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 399A41495725 for ; Mon, 27 Oct 2008 19:16:56 -0700 (PDT) Received: from ciao.gmane.org (main.gmane.org [80.91.229.2]) by cuda.sgi.com with ESMTP id ZyQa614F02ecdw7F for ; Mon, 27 Oct 2008 19:16:56 -0700 (PDT) Received: from list by ciao.gmane.org with local (Exim 4.43) id 1Kue8a-0003sD-Ht for linux-xfs@oss.sgi.com; Tue, 28 Oct 2008 02:16:52 +0000 Received: from 75-134-105-39.dhcp.aldl.mi.charter.com ([75.134.105.39]) by main.gmane.org with esmtp (Gmexim 0.1 (Debian)) id 1AlnuQ-0007hv-00 for ; Tue, 28 Oct 2008 02:16:52 +0000 Received: from mlueck by 75-134-105-39.dhcp.aldl.mi.charter.com with local (Gmexim 0.1 (Debian)) id 1AlnuQ-0007hv-00 for ; Tue, 28 Oct 2008 02:16:52 +0000 X-Injected-Via-Gmane: http://gmane.org/ To: linux-xfs@oss.sgi.com From: Michael Lueck X-ASG-Orig-Subj: Re: Bad day with xfsrestore, what went wrong?

You put a smile on my face. I worked out that syntax about 5 years ago, keep it in a text file, update as needed, and paste it into an SSH session.

It's doing a single page allocation at a time. It may be that this failure is caused by an increase base memory consumption of the kernel as this failure was reported in an lguest and reproduced with a simple 'modprobe xfs ; mount /dev/xxx /mnt/xfs' command.

How expensive is this operation (rule of thumb)? We will mostly use this on compute nodes where the partition is 500-750 GB large and the node has 8 GB of memory. For the simple test where I apparently hit thin air I have not seen anything bad in terms of memory consumption.

However, when I look at a file on this FS, e.g. ls -l /local/MCP/root/root.tar.bz2 ---xr-xr-- 1 root root 134 Sep 26 15:20 /local/MCP/root/root.tar.bz2 where /local is in /dev/sda6 (nevermind the weird permissions).

Thanks for the hint. backports.org doesn't contain a 2.6.26 and AFAIK lenny will ship with 2.6.26 as well, thus I'd like to try that one before doing a backport of 2.6.27 from sid myself. Thus I hope the issue that is triggered on those servers is fixed with 2.6.26 or some prior kernel since 2.6.21 already. If not, we will consider backporting 2.6.27. At least on my notebook I didn't have any issues so far with any kernel since 2.6.17.7. But even with TuxOnIce it doesn't have uptimes of 100 days or more, since I compile a new kernel for it once in a while. -- Martin Steigerwald - team(ix) GmbH - http://www.teamix.de gpg: 19E3 8D42 896F D004 08AC A0CA 1E10 C593 0399 AE90 From owner-xfs@oss.sgi.com Tue Oct 28 02:14:47 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.5 required=5.0 tests=BAYES_00,J_CHICKENPOX_62 autolearn=unavailable version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.168.29]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9S9Ekgm008956 for ; Tue, 28 Oct 2008 02:14:47 -0700 X-ASG-Debug-ID: 1225185286-577b01b90000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from bombadil.infradead.org (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id EB22B550D02 for ; Tue, 28 Oct 2008 02:14:46 -0700 (PDT) Received: from bombadil.infradead.org (bombadil.infradead.org [18.85.46.34]) by cuda.sgi.com with ESMTP id KFYvrGGelncRHsuv for ; Tue, 28 Oct 2008 02:14:46 -0700 (PDT) Received: from hch by bombadil.infradead.org with local (Exim 4.68 #1 (Red Hat Linux)) id 1Kukf0-00059T-9N; Tue, 28 Oct 2008 09:14:46 +0000 Date: Tue, 28 Oct 2008 05:14:46 -0400 From: Christoph Hellwig To: Christoph Hellwig , xfs@oss.sgi.com X-ASG-Orig-Subj: Re: [PATCH 7/7] split up xlog_recover_process_iunlinks Subject: Re: [PATCH 7/7] split up xlog_recover_process_iunlinks Message-ID: <20081028091446.GB1662@infradead.org> References: <20081027133938.GH1109@infradead.org> <20081028071750.GV4985@disturbed> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20081028071750.GV4985@disturbed> User-Agent: Mutt/1.5.18 (2008-05-17) X-SRS-Rewrite: SMTP reverse-path rewritten from by bombadil.infradead.org See http://www.infradead.org/rpr.html X-Barracuda-Connect: bombadil.infradead.org[18.85.46.34] X-Barracuda-Start-Time: 1225185286 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: 1.77 X-Barracuda-Spam-Status: No, SCORE=1.77 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests=RATWARE_EFROM X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.8889 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 3.79 RATWARE_EFROM Bulk email fingerprint (envfrom) found X-Virus-Scanned: ClamAV version 0.91.2, clamav-milter version 0.91.2 on oss.sgi.com X-Virus-Status: Clean > > + error = xfs_iget(mp, NULL, ino, 0, 0, &ip, 0); > > + if (error) > > + goto fail; > > + > > + /* > > + * Get the on disk inode to find the next inode in the bucket. > > + */ > > + ASSERT(ip != NULL); > > + error = xfs_itobp(mp, NULL, ip, &dip, &ibp, 0, 0, XFS_BUF_LOCK); > > + if (error) > > + goto fail; > > Jumping to 'fail' at this point leaks the xfs_inode returned from > xfs_iget().

I could provide you a single patch > rollup against mainline if it helps. BTW. XFS seems to be doing something interesting with my simple sync test case with IO error injection. I map a file MAP_SHARED into a number of processes, which then each run a loop that dirties the memory then calls msync(MS_SYNC) on the range. ext2 mostly reports -EIO back to userspace when a failure is injected AFAIKS. ext3 (ordered) doesn't until a lot of errors have been injected, but eventually reports -EIO and shuts down the filesystem. reiserfs seems to report failure more consistently. I haven't seen any -EIO failures from XFS... maybe I'm just not doing the right thing, or there is a caveat I'm not aware of. All fault injections I noticed had a trace like this: FAULT_INJECTION: forcing a failure Call Trace: 9f9cd758: [<6019f1de>] random32+0xe/0x20 9f9cd768: [<601a31b9>] should_fail+0xd9/0x130 9f9cd798: [<6018d0c4>] generic_make_request+0x304/0x4e0 9f9cd7a8: [<60062301>] mempool_alloc+0x51/0x130 9f9cd858: [<6018e6bf>] submit_bio+0x4f/0xe0 9f9cd8a8: [<60165505>] xfs_submit_ioend_bio+0x25/0x40 9f9cd8c8: [<6016603c>] xfs_submit_ioend+0xbc/0xf0 9f9cd908: [<60166bf9>] xfs_page_state_convert+0x3d9/0x6a0 9f9cd928: [<6005d515>] delayacct_end+0x95/0xb0 9f9cda08: [<60166ffd>] xfs_vm_writepage+0x6d/0x110 9f9cda18: [<6006618b>] set_page_dirty+0x4b/0xd0 9f9cda58: [<60066115>] __writepage+0x15/0x40 9f9cda78: [<60066775>] write_cache_pages+0x255/0x470 9f9cda90: [<60066100>] __writepage+0x0/0x40 9f9cdb98: [<600669b0>] generic_writepages+0x20/0x30 9f9cdba8: [<60165ba3>] xfs_vm_writepages+0x53/0x70 9f9cdbd8: [<600669eb>] do_writepages+0x2b/0x40 9f9cdbf8: [<6006004c>] __filemap_fdatawrite_range+0x5c/0x70 9f9cdc58: [<6006026a>] filemap_fdatawrite+0x1a/0x20 9f9cdc68: [<600a7a05>] do_fsync+0x45/0xe0 9f9cdc98: [<6007794b>] sys_msync+0x14b/0x1d0 9f9cdcf8: [<60019a70>] handle_syscall+0x50/0x80 9f9cdd18: [<6002a10f>] userspace+0x44f/0x510 9f9cdfc8: [<60016792>] fork_handler+0x62/0x70 And the kernel would sometimes say this: Buffer I/O error on device ram0, logical block 279 lost page write due to I/O error on ram0 Buffer I/O error on device ram0, logical block 379 lost page write due to I/O error on ram0 Buffer I/O error on device ram0, logical block 389 lost page write due to I/O error on ram0 I think I also saw a slab bug when running dbench with fault injection on.

We've got a rolling transaction in progress, and the commit of the first part of the transaction has got the I/O error. That frees the transaction structure used during that commit, as well as the ticket. However, before we committed the initial transaction, we duplicated the transaction structure to allow the transaction to continue to track all the dirty objects in the first commit. That included duplicating the pointer to the ticket. Then the EIO is returned to mkdir code with the duplicated transaction, which is then cancelled, and that frees the transaction and the ticket it holds. However, we'd already freed the ticket. Ok, we're only seeing this problem now because I recently modified the ticket allocation to use a slab instead of a roll-your-own free list structure that wouldn't have been poisoned. Nice to know that this change did more than just remove code. ;) This might take a little while to fix - a lot of code needs auditing - but thanks for reporting the problem.

Good catch. I can't believe I recently fixed a bug that touched these lines of code without noticing the inversion. Sometimes I wonder if we should just conver the entire of XFS to return negative errors - mistakes in handling negative error numbers in the core XFS code happen all the time. FWIW, the core issue here is that we've got to do the filemap_fdatawait() call in the ->fsync method because ->fsync gets called before we've waited for the data I/O to complete. XFS updates inode state on I/O completion, so we *must* wait for data I/O to complete before logging the inode changes. I think btrfs has the same problem.... Thanks again, Nick.

Ok, I was right - these problems happen all the time. The above call should really call xfs_flush_pages() to do the flush and wait. I note that xfs_flush_pages() returns negative errors, and all the callers expect positive errors. I bet the same occurs for xfs_flushinval_pages() and xfs_tosspages() which are the wrappers that core XFS code is supposed to be using for flushing and invalidating file ranges.... I'll write up a patch that covers all of these.

Heh, yeah it seems a bit tricky. BTW. feel free to add Signed-off-by: Nick Piggin if you would like to merge it, or alternatively if you fix it another way then I can rerun the test in 2 minutes if it is not 100% obviously correct. BTW. XFS seems to really be a lot more consistent than ext3 (ordered) in reporting EIO with this change in place. I don't know why exactly, but in ext3 I can see hundreds or thousands of failures injected in this manner: FAULT_INJECTION: forcing a failure Call Trace: 9ebe17f8: [<6019f34e>] random32+0xe/0x20 9ebe1808: [<601a3329>] should_fail+0xd9/0x130 9ebe1838: [<6018d234>] generic_make_request+0x304/0x4e0 9ebe1848: [<600622e1>] mempool_alloc+0x51/0x130 9ebe18f8: [<6018e82f>] submit_bio+0x4f/0xe0 9ebe1948: [<600a8969>] submit_bh+0xd9/0x130 9ebe1978: [<600aab08>] __block_write_full_page+0x198/0x310 9ebe1988: [<600a8487>] alloc_buffer_head+0x37/0x50 9ebe19a0: [<600f6ec0>] ext3_get_block+0x0/0x110 9ebe19d8: [<600f6ec0>] ext3_get_block+0x0/0x110 9ebe19e8: [<600aad48>] block_write_full_page+0xc8/0x100 9ebe1a38: [<600f8951>] ext3_ordered_writepage+0xd1/0x180 9ebe1a48: [<6006616b>] set_page_dirty+0x4b/0xd0 9ebe1a88: [<600660f5>] __writepage+0x15/0x40 9ebe1aa8: [<60066755>] write_cache_pages+0x255/0x470 9ebe1ac0: [<600660e0>] __writepage+0x0/0x40 9ebe1bc8: [<60066990>] generic_writepages+0x20/0x30 9ebe1bd8: [<600669db>] do_writepages+0x3b/0x40 9ebe1bf8: [<6006006c>] __filemap_fdatawrite_range+0x5c/0x70 9ebe1c58: [<6006028a>] filemap_fdatawrite+0x1a/0x20 9ebe1c68: [<600a7a15>] do_fsync+0x45/0xe0 9ebe1c98: [<6007792b>] sys_msync+0x14b/0x1d0 9ebe1cf8: [<60019a70>] handle_syscall+0x50/0x80 9ebe1d18: [<6002a10f>] userspace+0x44f/0x510 9ebe1fc8: [<60016792>] fork_handler+0x62/0x70 Buffer I/O error on device ram0, logical block 8228 lost page write due to I/O error on ram0 But eventually the filesystem aborts when we get a journal writing error, and sometimes I see a single EIO to msync, sometimes not (cc ext3 list).

Just be careful -- in your xfs_flush_pages, I think after the first filemap_fdatawrite, the mapping may no longer be tagged with PAGECACHE_TAG_DIRTY, so you may not pick up those writeback ones you need to wait on. Might need a different variant, or we could just bite the bullet and push through the ->fsync conversion so you get full control of the writeout. BTW. the Linux pagecache APIs should support range operations quite nicely for these. Any reason not to use them (it looks like the wrappers can take ranges)?

Yes, I realised this as soon as I looked at the code. I added xfs_wait_on_pages() to do this wait. ;) > Might need a different variant, or we could just bite the bullet and > push through the ->fsync conversion so you get full control of the > writeout.

Any reason not to use them (it looks like the > wrappers can take ranges)? Because I haven't got around to modifying these wrappers now that the range primitives are in place - XFS inherited the range operations from Irix and have sat unimplemented since being ported to Linux. The patch below should fix this entire class of error value screwup in XFS. I've just started running it through XFSQA, so it's not really tested yet. FWIW, your entire patch series made it through XFSQA without any new regressions, so it looks good from that POV. Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: fix error inversion problems with data flushing XFS gets the sign of the error wrong in several places when gathering the error from generic linux functions. These functions return negative error values, while the core XFS code returns positive error values. Hence when XFS inverts the error to be returned to the VFS, it can incorrectly invert a negative error and this error will be ignored by the syscall return. Fix all the problems related to calling filemap_* functions. Problem initially identified by Nick Piggin in xfs_fsync().

I don't see why not - I/O completion is only touching the XFS inode. XFS has it's own inode locks for I/O and inode exclusion, and the mapping tree lock protects the tree walk that the fdatawait is doing... > There was some talk IIRC about moving all this logic into the filesystem > to provide more flexibility here.

Yeah, the 1st bit I quite like and is similar to what I did in some nfs4acl code, as you know. We put all the EPERM cases early on which is nice. > There is a slight change in behaviour > as inode_change_ok doesn't allow i_mode updates to add the suid or sgid > without superuser privilegues while the old XFS code just stripped away > those bits from the file mode. > This bit is of concern for me. And I want to understand. It seems confusing. So for xfs, we currently have it that if we try to set the suid/sgid bit on the mode, and we are not the owner/group-member, and we don't have CAP_FSETID, then we clear that bit out of the mode (setuid/setgid) that we were going to set below. Now in inode_change_ok() we have some relevant code: /* Make sure a caller can chmod. */ if (ia_valid & ATTR_MODE) { if (!is_owner_or_cap(inode)) goto error; /* Also check the setgid bit! */ if (!in_group_p((ia_valid & ATTR_GID) ? attr->ia_gid : inode->i_gid) && !capable(CAP_FSETID)) attr->ia_mode &= ~S_ISGID; } It "looks" like it is doing a similar thing for the S_ISGID case but not for the S_ISUID case. And then we have similar code in inode_setattr() if (ia_valid & ATTR_MODE) { umode_t mode = attr->ia_mode; if (!in_group_p(inode->i_gid) && !capable(CAP_FSETID)) mode &= ~S_ISGID; inode->i_mode = mode; } But what about the suid case? And also, what is with the ATTR_KILL_* bits? Lemme look... should_remove_suid: CAP_FSETID -> return 0 else -> return (S_ISUID ? ATTR_KILL_SUID : 0) | (S_ISGID & S_IXGRP ? ATTR_KILL_SGID : 0) do_truncate: /* Remove suid/sgid on truncate too */ newattrs.ia_valid |= should_remove_suid(dentry); err = notify_change(dentry, &newattrs); Oh okay, so in notify_change() we clear the S_SUID/S_SGID bits in the cases that ATTR_KILL_SUID/ATTR_KILL_SGID are set and let lower setattr funcs interpret the KILL bits (as said in a comment). Hmmm....but it first clears the bits out of the attr->ia_mode so it does interpret them.

The patch below should fix this problem. It's about 10% of the way through XFSQA, which means there's nothing obviously bad about it, but it will need many more eyes on it before we decide if this is the best way to fix the problem.... Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS: Fix double free of log tickets When an I/O error occurs during an intermediate commit on a rolling transaction, xfs_trans_commit() will free the transaction structure and the related ticket. However, the duplicate transaction that gets used as the transaction continues still contains a pointer to the ticket. Hence when the duplicate transaction is cancelled and freed, we free the ticket a second time. Add reference counting to the ticket so that we hold an extra reference to the ticket over the transaction commit. We drop the extra reference once we have checked that the transaction commit did not return an error, thus avoiding a double free on commit error. Credit to Nick Piggin for tripping over the problem.

Can you also merge xfs_fsync into xfs_file_fsync while you're at it? The split newer made any sense as xfs_fsync is as Linux-specific as it gets and shouldn't be in the pseudo OS-independent layer.

What can happen by side effect (depending on the implementation) is that you can actually force out all data for any file. I found that you can approach non-fsync speeds for an fsync per file workload by simply writing all of the files out, then going back and fsync'ing them one at a time (last file first makes a bit of a difference). With that technique, you do get the hard promise of full data integrity and high speed. This is useful when you want to do bulk writes (tar, etc) ric From owner-xfs@oss.sgi.com Wed Oct 29 07:57:31 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=unavailable version=3.3.0-rupdated Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9TEvUIU021605 for ; Wed, 29 Oct 2008 07:57:31 -0700 X-ASG-Debug-ID: 1225292250-209100f20000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from rgminet13.oracle.com (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 9D03014A8B54 for ; Wed, 29 Oct 2008 07:57:30 -0700 (PDT) Received: from rgminet13.oracle.com (rcsinet13.oracle.com [148.87.113.125]) by cuda.sgi.com with ESMTP id iYH9YmmR6YjgKUTv for ; Wed, 29 Oct 2008 07:57:30 -0700 (PDT) Received: from rgminet15.oracle.com (mail-router.oracle.com [148.87.113.117]) by rgminet13.oracle.com (Switch-3.3.1/Switch-3.3.1) with ESMTP id m9TEuqI9020815 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=OK); Wed, 29 Oct 2008 14:56:53 GMT Received: from acsmt700.oracle.com (acsmt700.oracle.com [141.146.40.70]) by rgminet15.oracle.com (Switch-3.3.1/Switch-3.3.1) with ESMTP id m9TEufD8001332; Wed, 29 Oct 2008 14:56:42 GMT Received: from [192.168.1.15] (/72.225.43.119) by default (Oracle Beehive Gateway v4.0) with ESMTP ; Wed, 29 Oct 2008 14:56:38 +0000 X-ASG-Orig-Subj: Re: [patch 0/9] writeback data integrity and other fixes (take 3) Subject: Re: [patch 0/9] writeback data integrity and other fixes (take 3) From: Chris Mason To: Ric Wheeler Cc: Jamie Lokier , Nick Piggin , Christoph Hellwig , linux-nfs@vger.kernel.org, akpm@linux-foundation.org, xfs@oss.sgi.com, linux-fsdevel@vger.kernel.org In-Reply-To: <490865E3.8070102@gmail.com> References: <20081028144715.683011000@suse.de> <20081028153953.GB3082@wotan.suse.de> <20081028222746.GB4985@disturbed> <20081029001653.GF15599@wotan.suse.de> <20081029031645.GE4985@disturbed> <20081029091203.GA32545@infradead.org> <20081029092143.GA5953@wotan.suse.de> <20081029094417.GA21824@infradead.org> <20081029103029.GC5953@wotan.suse.de> <20081029122234.GE846@shareable.org> <490865E3.8070102@gmail.com> Content-Type: text/plain Date: Wed, 29 Oct 2008 10:56:36 -0400 Message-Id: <1225292196.6448.263.camel@think.oraclecorp.com> Mime-Version: 1.0 X-Mailer: Evolution 2.22.2 Content-Transfer-Encoding: 7bit X-Source-IP: acsmt700.oracle.com [141.146.40.70] X-Auth-Type: Internal IP X-CT-RefId: str=0001.0A090209.490879AC.01ED:SCFSTAT928724,ss=1,fgs=0 X-Barracuda-Connect: rcsinet13.oracle.com[148.87.113.125] X-Barracuda-Start-Time: 1225292250 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: -2.02 X-Barracuda-Spam-Status: No, SCORE=-2.02 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.8979 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- On Wed, 2008-10-29 at 09:32 -0400, Ric Wheeler wrote: > Jamie Lokier wrote: > >> Is there anything that particularly makes it a file operation > >> as opposed to an inode operation? > >> > > > > In principle, is fsync() required to flush all dirty data written > > through any file descriptor ever, or just dirty data written through > > the file descriptor used for fsync()? > > > > -- Jamie > > -- > > > http://www.opengroup.org/onlinepubs/009695399/functions/fsync.html > > Is a pointer to what seems to be the official posix spec for this - it > is definitely per file descriptor, not per file system, etc... > Maybe I'm reading Jamie's question wrong, but I think he's saying: /* open exactly the same file twice */ fd = open("file"); fd2 = open("file"); write(fd, "stuff") write(fd2, "more stuff") fsync(fd); Does the fsync promise "more stuff" will be on disk?

This adds a new output flag, BMV_OF_LAST to indicate if we've hit the last extent in the inode. This potentially saves an extra call from userspace to see when the whole mapping is done. It also adds BMV_IF_DELALLOC and BMV_OF_DELALLOC to request, and indicate, delayed-allocation extents. In this case bmv_block is set to -2 (-1 was already taken for HOLESTARTBLOCK; unfortunately these are the reverse of the in-kernel constants.) These new flags facilitate addition of the new fiemap interface. Rather than adding sh_delalloc, remove sh_unwritten & just test the flags directly.

Well it is kindof. Because we'd call Linux library functions directly from the method we skip to places that need sign conversion and could possibly go wrong.

Well, the patch I posted to fix the sign problems covered the xfs_flush_pages() and xfs_flushinval_pages() functions that we returning negative errors to core code, and none of the core code inverted that before returning it to functions that inverted it. That's a general problem that affected truncate, direct I/O, getbmap, etc, as well as fsync...

Or over to vger, as we've been discussing. I'd like to delay any significant change until (a) after we have git'ified our patch flow and tree management processes (shortly after the .28 pull req goes out), and (b) the new oss.sgi.com has been set up and all content rsync'd across. This machine exists but Trev is currently occupied on other tasks. We're going to want more than just a new mailing list or handler. We also need a wiki for docs (news, arch, blogs, training, papers, etc), something like patchwork for tracking submissions, and more, etc. It doesn't make much sense to start setting this up on the current oss and then do it all again on the new oss. So can we please hobble along for another week or two?

That should be trivial to fix up; we just need to avoid XFS_INEW() inodes in xfs_sync_inodes_ag() and probably also in xfs_qm_dqrele_all(), and that will mean the assert needs to be removed as well. Patch soon.

Test 182 writes a bunch of files, then runs sync, then shuts the filesystem down. It then unmounts and remounts the fs and checks that all the files are the correct length and have the correct contents. i.e. that sync semantics have been correctly observed. The cause of the failure is that log recovery is replaying inode allocation and overwriting the last inode writes that contained unlogged changes (i.e. the inode size update that occurs at I/O completion). The problem is that we've never been able to work out why recovery is doing this. What has been nagging at the back of my mind for quite some time is the fact that we do actually write these inodes to disk and that should allow the tail of the log to move forward past the inode allocation transaction and hence it should not be replayed during recovery. A solution that has been proposed in the past (by Lachlan) is to log the inode size updates instead of writing the inode to disk. In that case, recovery also replays the inode modification transactions and so we don't lose anything. It is a solution that would fix the problem. However, always logging inodes instead of writing unlogged changes has other performance implications that we'd prefer to avoid (i.e. the number of extra transactions it will cause). This solution also seemed to me to be papering over the real problem which we hadn't yet found because it did not explain why we were replaying an allocation that we should not need to. Hence the problem has gone unfixed since Lachlan first discovered it despite trying several times to get to the bottom of the problem. Now I think I finally have. I started by instrumenting the sync code and the inode dirtying and writeback code to confirm the order of data, inode and sync operations, with a view to understanding why the tail of the log was not moving forwards when the inode clusters were written out during the sync. To start with, let's look at what do_sync() does: 24 static void do_sync(unsigned long wait) 25 { 26 wakeup_pdflush(0); 27 sync_inodes(0); /* All mappings, inodes and their blockdevs */ 28 DQUOT_SYNC(NULL); 29 sync_supers(); /* Write the superblocks */ 30 sync_filesystems(0); /* Start syncing the filesystems */ 31 sync_filesystems(wait); /* Waitingly sync the filesystems */ 32 sync_inodes(wait); /* Mappings, inodes and blockdevs, again. */ 33 if (!wait) 34 printk("Emergency Sync complete\n"); 35 if (unlikely(laptop_mode)) 36 laptop_sync_completion(); 37 } Let's translate this into what XFS does: wakeup_pdflush(0) [*] - run a concurrent background sync of the fs via pdflush. sync_inodes(0) - walks the superblock dirty inode list doing an async flush of inodes and their data. sync_supers() - writes the superblock, forces the log to disk sync_filesystems(0) - non block filesystem sync. XFS writes the superblock sync_filesystems(1) - XFS writes all dirty data to disk and waits for it. Dirties the superblock and the log. Does not write inodes. sync_inodes(1) - walk the superblock dirty inode list *twice*, first doing an async flush of dirty data and inodes, secondly doing a sync flush of remaining dirty data and inodes. [*] Starting pdflush to sync data in the background when we are about to start flushing ourselves is self-defeating. instead of having a single thread doing optimal writeout patterns, we now have two threads trying to sync the same filesystems and competing with each other to write out dirty inodes. This actually causes bugs in sync because pdflush is doing async flushes. Hence if pdflush races and wins during the sync flush part of the sync process, sync_inodes(1) will return before all the data/metadata is on disk because it can't be found to be waited on. Now the sync is _supposedly_ complete. But we still have a dirty log and superblock thanks to delayed allocation that may have occurred after the sync_supers() call. Hence we can immediately see that we cannot *ever* do a proper sync of an XFS filesystem in Linux without modifying do_sync() to do more callouts. Worse, XFS can also still have *dirty inodes* because sync_inodes(1) will remove inodes from the dirty list in the async pass, but they can get dirtied a short time later (if they had dirty data) when the data I/O completes. Hence if the second sync pass completes before the inode is dirtied again we'll miss flushing it. This will mean we don't write inode size updates during sync. This is the same race that pdflush running in the background can trigger. Clearly this is broken, but this particular problem is an XFS bug and is fixed by XFS marking the inode dirty before I/O dispatch if the end offset of the I/O is beyond the current EOF so there is no window where the inode is temporarily clean. This, however, does not fix the race condition between the sync thread and pdflush, just the async-then-sync problem within the flush thread. Back to do_sync(), the order of operations we need to reliably sync a journalling filesystem that uses delayed allocation and updates metadata on data I/O completion is effectively as follows: - flush all dirty data - wait for all metadata updates caused by data flush to complete - force unwritten async transactions to disk to unpin dirty metadata - flush all dirty metadata - write the superblock In generic speak, this effectively requires: sync_filesystems(0) [**] sync_filesystems(1) sync_supers() sync_inodes(1) [***] sync_supers() [**] async flush optimisation [***] async flush optimisation is implemented internally to sync_inodes() for sync flushes. This leads to the following callouts and the behaviour that XFS would need for the callouts: sync_filesystems(0) ->sync_fs() - async flush all dirty data sync_filesystems(1) ->sync_fs() - sync flush remaining dirty data sync_supers() ->write_super() - write super, force the log sync_inodes(1) [****] sync_inodes_sb(0) - async flush of dirty inodes sync_inodes_sb(1) - sync flush of remaining inodes sync_supers() ->write_super() - write sb, force the log. [****] sync_inodes() really needs to fall down to a ->sync_inodes() callout for the filesystem to be able to implement an optimal inode flushing strategy. However, even with this order in place, test 182 still fails. So I looked at the filesystem prior to log recovery (mount -o ro,norecovery) and saw that all the data is on disk, all the inode sizes are correct, the superblock is up to date and everything looks OK. That is, the sync did everything it was supposed to and the above order of writing out the filesystem is working correctly. As soon as I ran recovery, though, I saw a small number of inodes go back to having an inode size of zero - they regress. The reason for this is that the log tail location (l_tail_lsn) at the end of the sync is was not updated on disk at the end of the sync and hence recovery is replaying transactions. At this point I wondered if the log covering code was not working properly. I'd never really looked at it in any detail, and as soon as I read the description I knew that it was not working. The problem log covering is supposed to solve is as follows (from fs/xfs/xfs_log_priv.h): 161 * These states are used to insert dummy log entries to cover 162 * space allocation transactions which can undo non-transactional changes 163 * after a crash. Writes to a file with space 164 * already allocated do not result in any transactions. Allocations 165 * might include space beyond the EOF. So if we just push the EOF a 166 * little, the last transaction for the file could contain the wrong 167 * size. If there is no file system activity, after an allocation 168 * transaction, and the system crashes, the allocation transaction 169 * will get replayed and the file will be truncated. This could 170 * be hours/days/... after the allocation occurred. Immediately it is was obvious that we're seeing the above problem and that log covering is a method for ensuring that the state of the log on disk is the same as that in memory at the end of a sync. Hence, as the last part of the sync we need to try to cover the log with a dummy transaction to update the real location of the log tail in the log. Therefore we will no longer replay the inode allocation transactions because the tail in the log matches the in memory state after the inodes have been flushed. With the current do_sync() code, we have no callout once the inodes are written to issue a dummy transactions to cover the log correctly. The do_sync() process needs to end with a sync_supers() to get the correct callout to XFS to allow this to happen. i.e. whenever we try to write the superblock we also should be trying to initiate the log covering process, and we can't do this right now. Once the log is covered, the recovery-overwriting-inodes problem goes away because recovery is not needed. Everyone understand the problem now? ;) FWIW, XFS has had this log covering code since, well, forever. It came from Irix and it worked on Irix. I don't think that it has ever worked on Linux, though, because of the lack of a sync_supers() call at the end of do_sync(1). We've just never noticed it until we corrected the infamous NULL files problems in 2.6.22 which hid this particular cause of file size mismatches after a crash. With a bunch of hacks in place, test 182 now passes and sync(1) on XFS finally does what it is supposed to. I'm not going to post the hacky, full-of-garbage, debuggy patch I have that I used to discover this - I'll clean it up first to just have the bits needed to fix the problem, then post it. That'll be tomorrow.... However, I have a problem - I'm an expert in XFS, not the other tens of Linux filesystems so I can't begin to guess what the impact of changing do_sync() would be on those many filesystems. How many filesystems would such a change break? Indeed - how many are broken right now by having dirty inodes and superblocks slip through sync(1)? And then the big question - how the hell does one test such change? I can test XFS easily enough because it has shutdown ioctls that effectively simulate a power failure - that what test 182 uses. I don't think any other filesystem has such an ioctl, though, and I don't have the time or hardware to repeatedly crash test every filesystem out there to prove that a change to do_sync() doesn't negatively impact them. What are the alternatives? do_sync() operates above any particular filesystem, so it's hard to provide a filesystem specific ->do_sync method to avoid changing sync order for all filesystems. Do we change do_sync() to completely sync a superblock at a time instead of doing each operation across all superblocks before moving onto the next operation? Is there any particular reason (e.g. performance, locking) for the current method that would prevent changing to completely-sync-a-superblock iteration algorithm so we can provide a custom ->do_sync method? Are there any other ways that we can get a custom ->do_sync method for XFS? I'd prefer a custom method so we don't have to revalidate every linux filesystem, especially as XFS already has everything it needs to provide it's own sync method (used for freezing) and a test suite to validate it is working correctly..... Are there any other options for solving this?

It is normal in unix-like operating systems to always flush everything dirty on the inode no matter what stream it arrived on. Flushing everything is permitted but not the requirement so applications must not expect this is *promised* or they will not be portable. It is only guaranteed that "stuff" in this example will be on disk. AFAIK the fsync semantic comes from the days of dinosaurs, mainframes, and minicomputers... when a lot of operating systems had user-space libraries that buffered the I/O. On fsync(fd), the "fd2" data would still be in user-space. jim From owner-xfs@oss.sgi.com Thu Oct 30 06:41:44 2008 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=unavailable version=3.3.0-rupdated Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.12.11.20060308/8.12.11/SuSE Linux 0.7) with ESMTP id m9UDfgdw007818 for ; Thu, 30 Oct 2008 06:41:44 -0700 X-ASG-Debug-ID: 1225374102-3252036c0000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from hackers.mr.itd.umich.edu (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 5EA091B6C89B for ; Thu, 30 Oct 2008 06:41:42 -0700 (PDT) Received: from hackers.mr.itd.umich.edu (smtp.mail.umich.edu [141.211.14.81]) by cuda.sgi.com with ESMTP id 7vOZtDhcTmwNsbb6 for ; Thu, 30 Oct 2008 06:41:42 -0700 (PDT) Received: FROM citi.umich.edu (dsl093-001-248.det1.dsl.speakeasy.net [66.93.1.248]) BY hackers.mr.itd.umich.edu ID 4909B97F.17A28.26555 ; 30 Oct 2008 09:41:19 -0400 Date: Thu, 30 Oct 2008 09:41:18 -0400 From: Jim Rees To: jim owens Cc: Nick Piggin , Chris Mason , Ric Wheeler , Jamie Lokier , Christoph Hellwig , linux-nfs@vger.kernel.org, akpm@linux-foundation.org, xfs@oss.sgi.com, linux-fsdevel@vger.kernel.org X-ASG-Orig-Subj: Re: [patch 0/9] writeback data integrity and other fixes (take 3) Subject: Re: [patch 0/9] writeback data integrity and other fixes (take 3) Message-ID: <20081030134118.GA31598@citi.umich.edu> References: <20081029031645.GE4985@disturbed> <20081029091203.GA32545@infradead.org> <20081029092143.GA5953@wotan.suse.de> <20081029094417.GA21824@infradead.org> <20081029103029.GC5953@wotan.suse.de> <20081029122234.GE846@shareable.org> <490865E3.8070102@gmail.com> <1225292196.6448.263.camel@think.oraclecorp.com> <20081030021601.GF18041@wotan.suse.de> <4909ADE0.1060205@hp.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <4909ADE0.1060205@hp.com> X-Barracuda-Connect: smtp.mail.umich.edu[141.211.14.81] X-Barracuda-Start-Time: 1225374103 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Barracuda-Spam-Score: -2.02 X-Barracuda-Spam-Status: No, SCORE=-2.02 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests= X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.1.9053 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- jim owens wrote: AFAIK the fsync semantic comes from the days of dinosaurs, mainframes, and minicomputers... when a lot of operating systems had user-space libraries that buffered the I/O.

Locking can't be the reason as we should never hold locks while returning from one of the VFS operations. I think it's performance or rather alledged performance as I think it doesn't really matter. If it matters however there is an easy method to make it perform just as well with a proper callout - just spawn a thread for every filesystem to perform it in parallel. > Are there any other ways that we can get a custom ->do_sync > method for XFS?

I think having a method for this would be useful. And given that a proper sync should be exactly the same as a filesysytem freeze we should maybe use one method for both of those and use the chance to give filesystem better control over the freeze process?

Sure, that will be faster as long as the filesystems are on separate devices.

Right - that's exactly where we should be going with this, I think. I'd suggest two callouts, perhaps: ->sync_data and ->sync_metadata. The freeze code can then still operate in two stages, and we can also use then for separating data and inode writeback in pdflush.... FWIW, I mentioned doing this sort of thing here: http://xfs.org/index.php/Improving_inode_Caching#Avoiding_the_Generic_pdflush_Code I think I'll look at redoing do_sync() to provide a custom sync method before trying to fix XFS....

As it is, here's the somewhat cleaned up patch that demonstrates the changes needed to make xfsqa test 182 pass.... Cheers, Dave. -- Dave Chinner david@fromorbit.com XFS, RFC: demonstration fix of test 182 This patch shows the various changes needed to ensure sync(1) leave the filesystem in a consistent state. It shows the different format of do_sync(), the changes to mark the inode dirty before data I/O and the changes to xfs_fs_write_super() and the functions it calls to ensure the log gets covered at the end of the sync. This is in no way a real fix for the problem, merely a demonstration of the problem. The real fix is to make the XFS sync code use the same flush algorithm as freeze, but that first requires VFS level changes to provide a method for doing so. --- fs/sync.c | 7 +++---- fs/xfs/linux-2.6/xfs_aops.c | 38 ++++++++++++++++++++++++++++---------- fs/xfs/linux-2.6/xfs_super.c | 29 +++++++++++------------------ fs/xfs/linux-2.6/xfs_sync.c | 41 ++++++++++++++++++++++++++--------------- fs/xfs/linux-2.6/xfs_sync.h | 2 +- 5 files changed, 69 insertions(+), 48 deletions(-) diff --git a/fs/sync.c b/fs/sync.c index 137b550..69f40b7 100644 --- a/fs/sync.c +++ b/fs/sync.c @@ -23,13 +23,12 @@ */ static void do_sync(unsigned long wait) { - wakeup_pdflush(0); - sync_inodes(0); /* All mappings, inodes and their blockdevs */ - DQUOT_SYNC(NULL); - sync_supers(); /* Write the superblocks */ sync_filesystems(0); /* Start syncing the filesystems */ sync_filesystems(wait); /* Waitingly sync the filesystems */ + DQUOT_SYNC(NULL); + sync_supers(); /* Write the superblocks */ sync_inodes(wait); /* Mappings, inodes and blockdevs, again. */ + sync_supers(); /* Write the superblocks, again */ if (!wait) printk("Emergency Sync complete\n"); if (unlikely(laptop_mode)) diff --git a/fs/xfs/linux-2.6/xfs_aops.c b/fs/xfs/linux-2.6/xfs_aops.c index f8fa620..cb79a21 100644 --- a/fs/xfs/linux-2.6/xfs_aops.c +++ b/fs/xfs/linux-2.6/xfs_aops.c @@ -143,19 +143,37 @@ xfs_destroy_ioend( } /* + * If the end of the current ioend is beyond the current EOF, + * return the new EOF value, otherwise zero. + */ +STATIC xfs_fsize_t +xfs_ioend_new_eof( + xfs_ioend_t *ioend) +{ + xfs_inode_t *ip = XFS_I(ioend->io_inode); + xfs_fsize_t isize; + xfs_fsize_t bsize; + + bsize = ioend->io_offset + ioend->io_size; + isize = MAX(ip->i_size, ip->i_new_size); + isize = MIN(isize, bsize); + return isize > ip->i_d.di_size ? isize : 0; +} + +/* * Update on-disk file size now that data has been written to disk. * The current in-memory file size is i_size.

Hence when XFS inverts the error to be returned to the VFS, it can incorrectly invert a negative error and this error will be ignored by the syscall return.

However, the duplicate transaction that gets used as the transaction continues still contains a pointer to the ticket. Hence when the duplicate transaction is cancelled and freed, we free the ticket a second time. Add reference counting to the ticket so that we hold an extra reference to the ticket over the transaction commit. We drop the extra reference once we have checked that the transaction commit did not return an error, thus avoiding a double free on commit error. Credit to Nick Piggin for tripping over the problem.

Logging the inode every time a file size update occured increased log traffic by about 11% for the load that test 182 generates. Logging the inode during inode writeout if, and only if, there are unlogged changes (ie i_update_core is set) has a negligible impact on log traffic or performance. I thought I understood this problem yet your description is a lot more detailed than I expected. I agree with you that sync is updating everything on disk and if it wasn't for log replay messing things up then everything would be good. So although the inode on disk is up to date the history of changes to that inode in the log is missing the last changes involving file size updates. So when the log is replayed the inode loses the file size update. And it's all because of the inode cluster buffer initialisation log entry that resets the cluster (and all the inodes in it) so even the di_flushiter hack can't save us. The obvious solution to me was to complete the history of the inode in the log so if replay wants to start from scratch it will make all the necessary changes to bring the inode to a state that matches what is on disk. Logging unlogged changes during sync will achieve this. Avoiding log replay altogether is even better but that solution is only going to work if we've run sync just before our system crashes. If we haven't run sync before our system crashes then we'll still hit this problem with regressing inodes but if we haven't run sync there are no guarantees, right? > > This solution also seemed to me to be papering over the real problem > which we hadn't yet found because it did not explain why we were > replaying an allocation that we should not need to.

Sometimes files are corrupted in such way as pasted below. This is in memory corruption since the file is correct after reboot. File size is unchanged as original, mtime not modified (compared to what I have in backup) according to ls -l. There is no oops, just contents of some files (it happens like 1 file per week, well I notice one file per week) are partially trashed. This is 230GB partition on lvm2, mounted with rw,nosuid,nodev,noatime,nodiratime,usrquota,grpquota options. Hardware is intel rack server (don't remember which one exactly) 1U with 2 x quad xeon, adaptec 3405, 4 SAS disks in raid5. Any ideas what that could be? /** * A class for reading Microsoft Excel Spreadsheets. * * Originally d4040\134040\134040\134040//"#,##0.00",^M\134012\134040\134040\134040\134040\134040\134040\134040\1340400x5\134040=>\134040"%1.0f",\134040\134040\134040\134040\134040/*"$#,##0;

It increases the number of transactions by 33%, (i.e one to create the file, one for the allocation, and an additional one for updating the file size). That means a significant increase in the CPU overhead involved in writing inodes via pdflush, and we've still got to write those inodes to disk at some point. Besides, what do we do when we write inodes back from the AIL and we find unlogged changes then? We can't issue transactions from the AIL, as that would deadlock if the log is full. And we can't not push the inodes out, as that will prevent the tail of the log moving forward and that will deadlock the filesystemi as well... On top of that, XFS already logs far, far too much information. We need to be decreasing logging overhead, not increasing it by a significant fraction.... > Logging the inode during inode writeout if, and only if, there are > unlogged changes (ie i_update_core is set) has a negligible impact on > log traffic or performance.

My last attempt at solving this problem a couple of months ago was based on this premise - it (successfully) avoided replaying the inode allocation transaction, but the inode still got overwritten. It got overwritten by the allocation transaction being replayed in exactly the manner described by the log covering code.... > The obvious solution to me was to complete the history of the inode in > the log so if replay wants to start from scratch it will make all the > necessary changes to bring the inode to a state that matches what is > on disk.

If the system crashes while busy, there's no guarantee that cached write-behind data has been written out, let alone the inode or the allocation transaction. Recent transactions will still be in memory, and log buffers may have been written out of order so on a crash we can lose up to the last 2MB of transactions from recovery. Logging inodes instead of writing them back does not change this at all - we just lose the inode changes from the log instead of from the on disk location. XFS has never attempted or claimed to provide data reliability guarantees when a crash occurs - it was designed to ensure that the filesystem metadata is consistent after recovery, not that there was zero data loss.....

Update: This issue has been addressed with a CVS fix on the 29th March 2007 and merged into mainline on 8th May 2007 for 2.6.22-rc1. XFS journals metadata updates, not data updates. After a crash you are supposed to get a consistent filesystem which looks like the state sometime shortly before the crash, NOT what the in memory image looked like the instant before the crash. Since XFS does not write data out immediately unless you tell it to with fsync, an O_SYNC or O_DIRECT open (the same is true of other filesystems), you are looking at an inode which was flushed out, but whose data was not. Typically you'll find that the inode is not taking any space since all it has is a size but no extents allocated (try examining the file with the xfs_bmap(8) command).

XFS has never done this. (explicitly overwrite with zeros, that is). There was a time in the past when after a truncate + size update + crash, the log would replay these metadata operations (truncate+size update) but the data blocks had never hit the disk (this is assuming there was no fsync complete), so there were no data blocks (extents) associated with the file - you wound up with a sparse file as a result. Reading this led to zeros, of course. This is NOT the same as "overwriting existing files with zeros" which xfs has *never* done. This particular behavior has been fixed in 2 ways, though. One, if a file has been truncated down, it will be synced on close: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=7d4fb40ad7efe4586d1341d4731377fb4530836f [XFS] Start writeout earlier (on last close) in the case where we have a truncate down followed by delayed allocation (buffered writes) - worst case scenario for the notorious NULL files problem. This reduces the window where we are exposed to that problem significantly. Two, a separate in-memory vs. on-disk size is now tracked: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ba87ea699ebd9dd577bf055ebc4a98200e337542 [XFS] Fix to prevent the notorious 'NULL files' problem after a crash. The problem that has been addressed is that of synchronising updates of the file size with writes that extend a file. Without the fix the update of a file's size, as a result of a write beyond eof, is independent of when the cached data is flushed to disk. Often the file size update would be written to the filesystem log before the data is flushed to disk. When a system crashes between these two events and the filesystem log is replayed on mount the file's size will be set but since the contents never made it to disk the file is full of holes. If some of the cached data was flushed to disk then it may just be a section of the file at the end that has holes. There are existing fixes to help alleviate this problem, particularly in the case where a file has been truncated, that force cached data to be flushed to disk when the file is closed. If the system crashes while the file(s) are still open then this flushing will never occur. The fix that we have implemented is to introduce a second file size, called the in-memory file size, that represents the current file size as viewed by the user. The existing file size, called the on-disk file size, is the one that get's written to the filesystem log and we only update it when it is safe to do so. When we write to a file beyond eof we only update the in- memory file size in the write operation. Later when the I/O operation, that flushes the cached data to disk completes, an I/O completion routine will update the on-disk file size. The on-disk file size will be updated to the maximum offset of the I/O or to the value of the in-memory file size if the I/O includes eof. ======== > This > would violate a basic requirement of Postfix (don't lose data after > fsync).

As long as postfix is looking after data properly with fsyncs etc, xfs should be perfectly safe w.r.t. data integrity on a crash. If you see any other behavior, it's a *bug* which should be reported, and I'm sure it would be fixed. As far as I know, though, there is no issue here. > Wietse > > To: Private List > From: "Theodore Ts'o" > Date: Sun, 19 Dec 2004 23:10:09 -0500 > Subject: Re: [evals] ext3 vs reiser with quotas > > [...] This email has been quoted too many times, and it's just not accurate. > This issue is completely different from the XFS issue of zero'ing > all open files on an unclean shutdown, of course.

And it's equally the job of the application; if an application uses the proper calls to sync data on xfs, xfs will not lose that data on a crash.

The specific question is, will unclean shutdown cause loss of data that was already fsynced, when the file was updated after the fsync. For example, if the on-disk file metadata is updated after the file data is appended, then there is no need to have a zero-fill problem after crash during append. What if the crash happens after Postfix requests a 1-byte write in the middle of a file, i.e. without changing the size? A reasonable implementation would not corrupt the file, but would either update the file data or not change it. I can deal with that.

Yeah, that's what I meant with my initial comment that we can grab the inodes anytime they are on the radix tree. Looks good.

And you weren't the first to thing of this. Reiser4 for example has bad a patch forever to turn sync_sb_inodes into a filesystem method, and I think something similar is what we want. When talking about syncing we basically want a few things: - sync out data, either async (from pdflush) or sync (from sync, freeze, remount ro or unmount) - sync out metadata (from pdflush), either async or sync (from sync, freeze, remount ro or unmount) and then we want pdflush / sync / etc call into it. If we are doing this correctly this would also avoid having our own xfssyncd. And as we found out it's not just sync that gets it wrong, it's also fsync (which isn't part of the above picture as it's per-inode) that gets this utterly wrong, as well as all kinds of syncs, not just the unmount one. Combine this with the other data integrity issues Nick found in write_cache_pages I come to the conclusion that this whole area needs some profound audit and re-architecture urgently.

Currently we iterate inodes for data and "metadata" sync, and the only other concept is writing superblocks. I think most filesystems have more types of metadata than this, so it makes sense for sync to work on abstracts sync as data and metadata rather than data, inodes and superblocks... > and then we want pdflush / sync / etc call into it.

Async writeback (write_inode()) has the same problem as fsync - writing the inode before waiting for data I/O to complete - which means we've got to jump through hoops in the filesystem to avoid blocking on inodes that can't be immediately flushed, and often we end up writing the inode multiple times and having to issue log forces whenw e shouldn't need to. Effectively we have to tell the VFS to "try again later" the entire time data is being flushed before we can write the inode and it's exceedingly inefficient..... > Combine this with the other data integrity issues Nick > found in write_cache_pages I come to the conclusion that this whole area > needs some profound audit and re-architecture urgently.

But in the current code sync(1) certainly never, ever triggers a superblock write we wait for...

XFS guarantees that you won't lose anything you fsync()d. You might lose what you wrote after the fsync()), though, because you haven't fsync()d it. Obvious, yes? > For example, if the on-disk file metadata is updated after the file > data is appended, then there is no need to have a zero-fill problem > after crash during append. In case you didn't read Eric's response - that's exactly how we fixed XFS to prevent this problem. And please stop propagating this erroneous "zero-fill" meme - Eric addressed how wrong that FUD is as well. > What if the crash happens after Postfix requests a 1-byte write in > the middle of a file, i.e. without changing the size?

That is exactly how XFS has always behaved for non-extending data overwrite. i.e. Exactly the same pretty much every filesystem that has ever existed.

With my patch to kill the shared readonly bits we should be able to make it use xfs_sync_fsdata for consistency.

Yes, absolutely. And for those that have inodes as primary / only metadata besides superblock we can still provide a generic_sync_inodes helper that just takes a callback to apply to every inode.

Yes, that was the couple of sync functions I meant above as the whole inode writeback path is extremly convoluted - mostly due to the dirty data vs metadata mixup mess.

And please stop propagating > this erroneous "zero-fill" meme - Eric addressed how wrong that > FUD is as well. Just confirming a specific case that I care about. Here's something I would like to know regarding the order of directory updates: - Does fsync(file) guarantee the file's directory entry is safe? Some file systems complete directory updates before the open/link/rename system call returns, so fsync() doesn't have to worry about it. - Does rename() guarantee that at least one directory entry will exist even when the system crashes in the middle of the operation? Postfix assumes both answers are "yes"; old ext2fs violated both assumptions. > > What if the crash happens after Postfix requests a 1-byte write in > > the middle of a file, i.e. without changing the size?

Thanks for confirming that XFS is not unusual. Wietse
