The new version acquires i_flags_lock early and only drops it once we need to call into inode_init_always or before calling xfs_ilock. This patch fixes a bug seen in the wild where we race modifying the reclaim tag.

The latest patch is for 2.6.30, then one before is for the current git tree. Note that the one for current git has a small buglet if you want to compile XFS as a module: in that case you need t ochange the EXPORT_SYMBOL of destroy_inode in fs/inode.c to an export for __destroy_inode.

The mainline 2.6.31 kernel made it to the 5th release candidate but besides a few kernel-wide patches touching XFS the only activity were two small patches fixing a bug in FIEMAP and working around writeback performance problems in the VM. A few more patches were posted to the list but haven't been merged yet. Two big patch series deal with theoretically possible deadlocks due to locks taken in reclaim contexts, which are now detected by lockdep. The pace on the userspace side has been slow. There have been a couple of fixes to xfs_repair and xfs_db, and xfstests grew a few more testcases.

OK, got it. Applied and compiled OK now. But I was trying to reproduce this one first without the patch and creating a similar or even bigger workload on the box: well, the "box" is a netbook (1 GB RAM, 1.6GHz Atom) and right now there are running 4 instances of bonnie++, 1 tar, 1 tiobench, 1 rsync all reading and writing from/to the same XFS partition as in my initial report, where only 1 rsync operation was in progress - which usually creates quite a lot I/O by itself, but I though I should hammer on the box a bit more to trigger this. Load is now at 13, far higher than it was yesterday, but no BUG or any sign of instability. (Hm, this is usually a good thing, right?) So, yes - I could now boot again with the fix applied, but I'm not sure what to report then, as it's not visible that something would be "fixed". Thanks, Christian. -- BOFH excuse #288: Hard drive sleeping. Let it wake up on it's own...

My guess is that the XFS_DIFLAG_REALTIME flag is being set incorrectly on the xfs inode structure, setting iomapp->iomap_target to the wrong device pointer (probably NULL). I don't know if this is the best place to add a check, neither if returning -XFS_ERROR(EIO) is correct at this point.

That's not only counter-intuitive because inode_init_always did not allocate the inode structure, but in case of XFS it's actively harmful as ->destroy_inode might delete the inode from a radix-tree that has never been added. This in turn might end up deleting the inode for the same inum that has been instanciated by another process and cause lots of cause subtile problems. Also in the case of re-initializing a reclaimable inode in XFS it would free an inode we still want to keep alive.

Until you wind up looking at a problem from some old kernel, or modified vendor kernel, and you realize that now you really don't know which error "xfs_iformat(6)" is anymore, and you either have to go digging through trees that aren't handy, or you just give up and don't bother to help because now it's too much of a pain. ;) But I can leave it up to the folks @ sgi, I can see both sides of the argument, and I won't care too much either way.

I'll take a look. The reason for the objdump was to try to work out where in xfs_rename we were erroring out, but in your case: xfs_rename+0x5ac/0x5af I guess it's the trans_cancel at the very end of the function on the goto : error cases. Is there any chance you could instrument xfs_rename so that for every goto abort_return and goto error_return you add a printk so we know which one you hit? Maybe something like: printk("line %s error %d\n", __LINE__, error); just before each goto, with appropriate braces {} sprinkled in as necessary? I can send a patch if that helps. Sorry for the brute-force debugging but not at all sure yet what this may be.

Same as Eric I don't think there's much of a point renumbering the error cases. Instead I'll do another patch with a couple of cleanups in this function replacing all the numbers with short alphabetic tags. I don't really see the point of printing the flags either, if we have this bit flipped it's pretty clear that we had random corruption of this dinode.

New version below: -- Subject: xfs: fix locking in xfs_iget_cache_hit From: Christoph Hellwig The locking in xfs_iget_cache_hit currently has numerous problems: - we clear the reclaim tag without i_flags_lock which protects modifications to it - we call inode_init_always which can sleep with pag_ici_lock held - we acquire and drop i_flags_lock a lot and thus provide no consistency between the various flags we set/clear under it This patch fixes all that with a major revamp of the locking in the function. The new version acquires i_flags_lock early and only drops it once we need to call into inode_init_always or before calling xfs_ilock. This patch fixes a bug seen in the wild where we race modifying the reclaim tag.

There was no indication for a hardware problem. HW Raid status was *OK* /var/log/messages lists several thousand lines like: Aug 6 21:12:03 nfsserver kernel: [7660448.840139] Filesystem "sdb1": corrupt dinode 4806258, (btree extents). Unmount and run xfs_repair. (allways the same dinode #) after stopping nfsd and unmounting the fs both xfs_check and xfs_repaier did not detect any corruption! back in service i got the same problem and log lines. So what is wrong here? There might be a fs issue and the fs utilitys are not able to detect it ? I did a metadata dump of that fs and could post it, would this help to determine what is going wrong here?

These three patches fix problems we intorduced when redoing the XFS inode caching in 2.6.29 (yes, that long ago). The actual fixes are mostly in inode.c, but in functionality that was only exported in that way for XFS and doesn't have other users, which the last patch just mostly splits up a function in XFS to fix the way we delete inodes that lost the race of adding them to the inode. As you can see by the Reported-by tags on the last patch tons of people hit it (probably the most I've ever seen for a single bug), and it's been harassing us for a long time, so I'd really like to see this getting into 2.6.31. It's been out on -fsdevel for review for a couple of days.

Definitely sensible approach for inode_init_always to be symmetric, and to not free what it didn't allocate.

We actually had the test two times in the old code, once for the reclaim case, and once after the igrab succeeded. I just moved it into a single command place. I've updated the comment to match that. New version below: -- Subject: xfs: fix locking in xfs_iget_cache_hit From: Christoph Hellwig The locking in xfs_iget_cache_hit currently has numerous problems: - we clear the reclaim tag without i_flags_lock which protects modifications to it - we call inode_init_always which can sleep with pag_ici_lock held (this is oss.sgi.com BZ #819) - we acquire and drop i_flags_lock a lot and thus provide no consistency between the various flags we set/clear under it This patch fixes all that with a major revamp of the locking in the function. The new version acquires i_flags_lock early and only drops it once we need to call into inode_init_always or before calling xfs_ilock. This patch fixes a bug seen in the wild where we race modifying the reclaim tag.

The fundamental design is mostly unchanged. What you might now want to bother reading of the original documents are: dir_design.pdf - the dir code has been completely replaced threads.pdf - this is totally IRIX specific scaffold.pdf - again mostly IRIX specific message.pdf - no idea what this is at all, I never saw traces of this in XFS For all others there's quite a bit of IRIXism in there.

If there are no patches against 2.6.29 then i have no other chance than trying this, or i switch to ext4. But what happens then? What a bullshit, from one bug to the next, my company kills me.

The i_lock mutex is taken in reclaim context so all allocations under it must avoid recursions into the filesystem. There are a couple more uses of xfs_buf_associate_memory in the log recovery code that are also affected by this, but I'd rather keep the code simple than passing on a gfp_mask argument. Longer term we should just stop requiring the memoery allocation in xlog_sync by some smaller rework of the buffer layer. Reported by the new reclaim context tracing in lockdep.

Ack. > Is there anything specific you're looking for? In my work, I've just begun to use XFS as the interface into a very large, virtual storage system, to great effect. It's my first direct interaction with the file system, and I've been hugely impressed with its power, speed and versatility. The only unresolved problem that we're experiencing has to do with file system corruption in a failover scenario, and my immediate need in understanding some of the internals is to wrap my hands around this problem (I may email this list with details if I can sufficiently explain myself). A more long-term need we have is for clustering support. I've read lightly about CXFS, though it appears to be inactive, or at least not open source. Has clustering support been discussed with the members here? If so, I'd like to take part in those conversations if there's sufficient interest to engage in that way. Thanks very much again.

Any failover you're doing would need to be handled outside the filesystem, of course; STONITH etc? I don't know that reading xfs internals will be all that relevant. But I suppose the details may help if you think it is an xfs-related problem. > A more long-term need we have is for clustering support.

CXFS is and probably will be the only direct clustering mechanism for xfs... it is still active, though as you note it is not (and probably will never be?) open source. block-layer failover should be as possible on xfs as any other filesystem, though. -Eric > Thanks very much again. > > John Quigley jquigley.com > From felixb@oss.sgi.com Tue Aug 11 16:05:54 2009 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-1.6 required=5.0 tests=ALL_TRUSTED,AWL,BAYES_00 autolearn=ham version=3.3.0-rupdated Received: from oss.sgi.com (localhost [127.0.0.1]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7BL5nHn156982 for ; Tue, 11 Aug 2009 16:05:54 -0500 Received: (from felixb@localhost) by oss.sgi.com (8.14.3/8.14.3/Submit) id n7BL5niF156932; Tue, 11 Aug 2009 16:05:49 -0500 Date: Tue, 11 Aug 2009 16:05:49 -0500 Message-Id: <200908112105.n7BL5niF156932@oss.sgi.com> From: xfs@oss.sgi.com To: xfs@oss.sgi.com Subject: [XFS updates] XFS development tree branch, master, updated. v2.6.30-rc4-1259-g79dd43b X-Git-Refname: refs/heads/master X-Git-Reftype: branch X-Git-Oldrev: 7509ee34a365c041718d0b676e5ee255b58b5dda X-Git-Newrev: 79dd43bb85d64ba14a781f940c858d7bbe8c9a6d This is an automated email from the git hooks/post-receive script.

The i_lock mutex is taken in reclaim context so all allocations under it must avoid recursions into the filesystem. There are a couple more uses of xfs_buf_associate_memory in the log recovery code that are also affected by this, but I'd rather keep the code simple than passing on a gfp_mask argument. Longer term we should just stop requiring the memoery allocation in xlog_sync by some smaller rework of the buffer layer. Reported by the new reclaim context tracing in lockdep.

On July 18th I noticed the first time this unaccountable decrease of free s= pace of my root partition /dev/hda7: =46or at least several boot-shutdown-cycles it has decreased on every cycle= by some 1020 =E2=80=A6 1030 blocks from originally above 100 MB to 96 MB. Expected change at most =C2=B11 block. Neither xfs_check nor xfs_repair -d= n could detect any flaws. I booted a sidux image with kernel 2.6.27, mounted /dev/hda7 readonly (actu= ally sidux flavour =E2=80=9C/dev/sda7=E2=80=9D), and compared reported free= space =E2=9E=9C decrease seems to occur on umount + system shutdown. Neit= her xfs_check nor =E2=80=9Cxfs_repair -dn=E2=80=9D running under sidux kern= el 2.6.27 could detect any flaws. Only one other flaw is noteworthy (seperate bugreport scheduled): Since one of the 2.6.28.? kernels mount procedures require a time randomly = dithering between less than 1 second and more than 30 seconds with almost n= o harddisk i/o activity, with NO difference between =E2=80=9Cmount -a=E2=80=9D during boot and manual mou= nts, NO difference between mounts of plain and loop-aes-encrypted partitions, NO difference between kernels 2.6.29.[1-6] and 2.6.30.4. Only loop mounts of vfat images happen without remarkable delay. Just after xfs_check and =E2=80=9Cxfs_repair -dn=E2=80=9D have verified a p= articular loop-aes-encrypted filesystem errorfree, kernel complains every t= ime =E2=80=9Csuperblock invalid=E2=80=9D and mounts it successfully. Kerne= l 2.6.30.4 shows the same crazy behavior on mounting of the same and additi= onally another particular loop-aes-encrypted filesystem. Cannot say, if th= is extreme slow mounts are XFS specific, because I do not use any other fil= esystem on this linux system. On August 10th =E2=80=94 after reading =E2=80=9Ckernel.org/ChangeLog-2.6.30= =2Ebz2: xfs: fix bad_features2 fixups for the root filesystem =E2=80=A6=E2= =80=9D =E2=80=94 I switched to kernel 2.6.30.4, which left the problem UNMO= DIFIED.

[1] the only exception is that log reocvery is performed when we attempt a read-only mount with an unclean log, that is the box crashed while writing the filesystems.

You can get it to flush extremely often by playing with /proc/sys/vm/dirty_expire_centiseconds and /proc/sys/vm/dirty_writeback_centisecs, though. Safer settings generally imply terrible performance, though, you've been warned. Ah another thing may be some cache option in the iSCSI target. what target are you using? =20 --=20 -------------------------------------------------- Emmanuel Florac www.intellique.com =20 -------------------------------------------------- From felixb@sgi.com Thu Aug 13 17:00:32 2009 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 relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7DM0Cb4053816 for ; Thu, 13 Aug 2009 17:00:22 -0500 Received: from estes.americas.sgi.com (estes.americas.sgi.com [128.162.236.10]) by relay2.corp.sgi.com (Postfix) with ESMTP id 2AA8F304089 for ; Thu, 13 Aug 2009 15:00:58 -0700 (PDT) Received: from eagdhcp-232-172.americas.sgi.com (eagdhcp-232-172.americas.sgi.com [128.162.232.172]) by estes.americas.sgi.com (Postfix) with ESMTP id BBB2E7000103; Thu, 13 Aug 2009 16:44:05 -0500 (CDT) Cc: XFS Development Message-Id: From: Felix Blyakher To: John Quigley In-Reply-To: <4A8474D2.7050508@jquigley.com> Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes Content-Transfer-Encoding: 7bit Mime-Version: 1.0 (Apple Message framework v926) Subject: Re: XFS corruption with failover Date: Thu, 13 Aug 2009 16:44:05 -0500 References: <4A8474D2.7050508@jquigley.com> X-Mailer: Apple Mail (2.926) X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean On Aug 13, 2009, at 3:17 PM, John Quigley wrote: > Folks: > > We're deploying XFS in a configuration where the file system is > being exported with NFS.

As I understand the desire to be able to issue 0 size writes from xfs_io is to test the possibility of writing to a given fd. What kind of errors would you expect to test for? Otherwise looks good.

Client's caching can't affect the metadata and the log in particular operations on the server. Client may indeed loose some data, but that's completely different issue.

This sort of thing in generic_write_checks(): if (unlikely(*pos >= inode->i_sb->s_maxbytes)) { if (*count || *pos > inode->i_sb->s_maxbytes) { return -EFBIG; } /* zero-length writes at ->s_maxbytes are OK */ } Although I'm a little confused about why "*pos == s_maxbytes" is ok; I thought s_maxbytes was a count/size whereas pos is an offset, so it seems to me that pos == s_maxbytes is one past the max. But anyway, that's mostly unrelated to the patch in this thread. :) -Eric > Otherwise looks good. > > Felix From sandeen@sandeen.net Thu Aug 13 19:27:23 2009 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.3 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 (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7E0R3dp060409 for ; Thu, 13 Aug 2009 19:27:13 -0500 X-ASG-Debug-ID: 1250209644-3b6102ab0000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mail.sandeen.net (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 4A8531B690B0 for ; Thu, 13 Aug 2009 17:27:24 -0700 (PDT) Received: from mail.sandeen.net (sandeen.net [209.173.210.139]) by cuda.sgi.com with ESMTP id oU4UeCa5dY1PpjfU for ; Thu, 13 Aug 2009 17:27:24 -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 mail.sandeen.net (Postfix) with ESMTP id 29C0FA9ED21; Thu, 13 Aug 2009 19:27:24 -0500 (CDT) Message-ID: <4A84AF6C.3010801@sandeen.net> Date: Thu, 13 Aug 2009 19:27:24 -0500 From: Eric Sandeen User-Agent: Thunderbird 2.0.0.22 (Macintosh/20090605) MIME-Version: 1.0 To: Michael Monnerie CC: xfs@oss.sgi.com X-ASG-Orig-Subj: Re: Resizing XFS on GPT partition Subject: Re: Resizing XFS on GPT partition References: <200908140148.28810@zmi.at> In-Reply-To: <200908140148.28810@zmi.at> 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: 1250209668 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: -1.61 X-Barracuda-Spam-Status: No, SCORE=-1.61 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests=SUBJECT_FUZZY_TION X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.2.6128 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.41 SUBJECT_FUZZY_TION Attempt to obfuscate words in Subject: X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean Michael Monnerie wrote: > I've had a XEN VM with a 90GB disk, increased it to 250GB. > Then I had the problem that I used GPT partitioning, meaning only > "parted" being usable. parted doesn't support resizing partitions for > xfs and refuses to do it. > > The simple thing is to delete and recreate with bigger size that > partition.

Are you sure? if (ohead->oh_clientid != XFS_TRANSACTION && ohead->oh_clientid != XFS_LOG) { xlog_warn( "XFS: xlog_recover_process_data: bad clientid"); ASSERT(0); return (XFS_ERROR(EIO)); } so it does say EIO but that seems to me to be the wrong error; loks more like a bad log to me.

Acknowledged; we've looked at GFS, and I've been meaning to read up on OCFS2. For various reasons, particularly performance, ease of deployment and flexible growth, XFS has been the clear winner in our particular case (and our case is fairly unique, as our volume is backed by a distributed storage device). > You can get it to flush extremely > often by playing with /proc/sys/vm/dirty_expire_centiseconds > and /proc/sys/vm/dirty_writeback_centisecs, though.

No caching target side - I can speak definitely on that because I wrote it (integrates with our data dispersal stack [1]). Also, we're utilizing the same target when failing over; it's just the ISCSI initiator (aka, the NFS server) that is changing.

It's for this reason that I assumed it's something we're doing wrong, and not an inherent issue with the file system. - John Quigley From jquigley@jquigley.com Thu Aug 13 19:55:47 2009 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-0.7 required=5.0 tests=AWL,BAYES_00,MISSING_HEADERS autolearn=no version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7E0tRfu062357 for ; Thu, 13 Aug 2009 19:55:37 -0500 X-ASG-Debug-ID: 1250211371-0472012d0000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mail.jquigley.com (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id B75253CB216 for ; Thu, 13 Aug 2009 17:56:11 -0700 (PDT) Received: from mail.jquigley.com (main.jquigley.com [67.23.32.156]) by cuda.sgi.com with ESMTP id EkDbDBiV5FgDxh9x for ; Thu, 13 Aug 2009 17:56:11 -0700 (PDT) Received: from [10.1.1.11] (OSH-NAT-213-122.onshore.net [66.146.213.122]) (Authenticated sender: jquigley@mail.jquigley.com) by mail.jquigley.com (Postfix) with ESMTPSA id 05388204116 for ; Fri, 14 Aug 2009 00:56:10 +0000 (UTC) Message-ID: <4A84B629.3080208@jquigley.com> Date: Thu, 13 Aug 2009 19:56:09 -0500 From: John Quigley User-Agent: Thunderbird 2.0.0.22 (Windows/20090605) MIME-Version: 1.0 CC: XFS Development X-ASG-Orig-Subj: Re: XFS corruption with failover Subject: Re: XFS corruption with failover References: <4A8474D2.7050508@jquigley.com> In-Reply-To: Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-Barracuda-Connect: main.jquigley.com[67.23.32.156] X-Barracuda-Start-Time: 1250211371 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: -0.44 X-Barracuda-Spam-Status: No, SCORE=-0.44 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests=MISSING_HEADERS X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.2.6128 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 1.58 MISSING_HEADERS Missing To: header X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean Felix Blyakher wrote: > This is an IO error.

This has been tested and fails, so it does appear to be a corruption issue on the stable media. Based on your first comment, I'm re-running tests to verify that the ISCSI volumes are fully online and ready to accept IO before mounting the file system.

So even though we are writing at the limit we are not actually going to write anything.

Hey Eric: That would certainly be consistent with our experience, as the only way we're able to bring the file system back online is by zeroing the log. > It does make me wonder if there's any sort of per-initiator caching on > the iscsi target or something. There isn't, as mentioned above, though we have several intermediate layers between the file system and iSCSI initiator, including multipath and LVM, both of which I was initially suspicious of. In testing with a similar scenario but in a more isolate fashion without those two intermediates, the behavior was still present. Also, just to clarify the topology: /-----[Failover Secondary]------\ / \ NFS Client ----/ \-----[ISCSI Target]----[Distributed Storage] \ / \ / \-----[Failover Primary]--------/ Those two failover machines, Primary and Secondary, act as the NFS server, the XFS mountpoint and ISCSI initiator. Only one failover machine is logged into the ISCSI target/has XFS mounted. Thanks very much for your cycles on this guys. - John Quigley From michael.monnerie@is.it-management.at Thu Aug 13 20:09:57 2009 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,J_CHICKENPOX_33 autolearn=no version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7E19V8B063464 for ; Thu, 13 Aug 2009 20:09:47 -0500 X-ASG-Debug-ID: 1250212205-2cf902b90000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mailsrv1.zmi.at (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 97F183CB055 for ; Thu, 13 Aug 2009 18:10:06 -0700 (PDT) Received: from mailsrv1.zmi.at (mailsrv1.zmi.at [212.69.162.198]) by cuda.sgi.com with ESMTP id StQ6E9yN1xtWaJNG for ; Thu, 13 Aug 2009 18:10:06 -0700 (PDT) Received: from mailsrv.i.zmi.at (unknown [81.217.106.33]) (using TLSv1 with cipher DHE-RSA-CAMELLIA256-SHA (256/256 bits)) (Client CN "mailsrv2.i.zmi.at", Issuer "power4u.zmi.at" (not verified)) by mailsrv1.zmi.at (Postfix) with ESMTP id A014F4EEE; Fri, 14 Aug 2009 03:09:34 +0200 (CEST) Received: from saturn.localnet (saturn.i.zmi.at [10.72.27.2]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (Client did not present a certificate) by mailsrv.i.zmi.at (Postfix) with ESMTPSA id 943CD400174; Fri, 14 Aug 2009 03:09:34 +0200 (CEST) From: Michael Monnerie Organization: it-management http://it-management.at To: xfs@oss.sgi.com X-ASG-Orig-Subj: Re: Resizing XFS on GPT partition Subject: Re: Resizing XFS on GPT partition Date: Fri, 14 Aug 2009 03:09:29 +0200 User-Agent: KMail/1.10.3 (Linux/2.6.30.4-ZMI; KDE/4.1.3; x86_64; ; ) Cc: Eric Sandeen References: <200908140148.28810@zmi.at> <4A84AF6C.3010801@sandeen.net> In-Reply-To: <4A84AF6C.3010801@sandeen.net> MIME-Version: 1.0 Content-Type: multipart/signed; boundary="nextPart37899587.xJ3sraQm2n"; protocol="application/pgp-signature"; micalg=pgp-sha1 Content-Transfer-Encoding: 7bit Message-Id: <200908140309.34058@zmi.at> X-Barracuda-Connect: mailsrv1.zmi.at[212.69.162.198] X-Barracuda-Start-Time: 1250212208 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: -1.61 X-Barracuda-Spam-Status: No, SCORE=-1.61 using per-user scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=2.1 tests=SUBJECT_FUZZY_TION X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.2.6128 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.41 SUBJECT_FUZZY_TION Attempt to obfuscate words in Subject: X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean --nextPart37899587.xJ3sraQm2n Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline On Freitag 14 August 2009 Eric Sandeen wrote: > File a bug against parted. =A0:) You think that's easy?

I think my confusion over maxbytes is whether it's a size or an offset. The comment says ... max size. Also in the above function it does i_size_read on the block device - again a size. If it's a max offset you're right; if it's a max -size- then pos == s_maxbytes is already off the end, one past the limit. -eric From sandeen@sandeen.net Thu Aug 13 20:35:06 2009 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.3 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7E1YkVl064898 for ; Thu, 13 Aug 2009 20:34:56 -0500 X-ASG-Debug-ID: 1250213722-046b01d20000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mail.sandeen.net (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id E68FB3CADE3 for ; Thu, 13 Aug 2009 18:35:22 -0700 (PDT) Received: from mail.sandeen.net (sandeen.net [209.173.210.139]) by cuda.sgi.com with ESMTP id rzF4SixsYJmIkn2l for ; Thu, 13 Aug 2009 18:35:22 -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 mail.sandeen.net (Postfix) with ESMTP id 36D1DA9BF33; Thu, 13 Aug 2009 20:35:22 -0500 (CDT) Message-ID: <4A84BF5A.8030502@sandeen.net> Date: Thu, 13 Aug 2009 20:35:22 -0500 From: Eric Sandeen User-Agent: Thunderbird 2.0.0.22 (Macintosh/20090605) MIME-Version: 1.0 To: Lachlan McIlroy CC: John Quigley , XFS Development , Felix Blyakher X-ASG-Orig-Subj: Re: XFS corruption with failover Subject: Re: XFS corruption with failover References: <1405534054.1935051250211481446.JavaMail.root@zmail05.collab.prod.int.phx2.redhat.com> In-Reply-To: <1405534054.1935051250211481446.JavaMail.root@zmail05.collab.prod.int.phx2.redhat.com> Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit X-Barracuda-Connect: sandeen.net[209.173.210.139] X-Barracuda-Start-Time: 1250213728 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 3.2.2.6129 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean Lachlan McIlroy wrote: > ----- "Eric Sandeen" wrote: > >> Felix Blyakher wrote: >>> On Aug 13, 2009, at 3:17 PM, John Quigley wrote: >>> >>>> Folks: >>>> >>>> We're deploying XFS in a configuration where the file system is >>>> being exported with NFS.

I didn't plan to send it out until I get my hands onto a TRIM capable device (or at least get time to add support to qemu), and so far it's only been tested in dry-run mode. The basic idea is to add an ioctl which walks the free space btrees in each allocation group and simply discard everythin that is free. Given that XFS doesn't gragment freespace very much that's a very efficient way to do it. In addition we also already support setting a threshold under which we don't bother to discard an extent, it's currently hardcoded in the helper tool. In the future we could also add things like a sequence number in the AG headers if anything has changed at all, but let's leave those optimizations until we need them. XFS locks the allocation btree using the btree buffers, so we do not block allocations from any extent which we're not currenly discarding. Now the caveat for that is that we really do want to do the discard synchronously, that is wait for the request to finish. That's what I've implemented in this patch, but it's the part I haven't been able to test so far. (and yes, this should be separate patch, but it's really just an RFC for now) Mark, any chance to try it? Just create an XFS filesystem, age it a bit and then call the attached little trim.c program on the mountmoint (or any file inside the filesystem for that matter) Index: linux-2.6/fs/xfs/linux-2.6/xfs_ioctl.c =================================================================== --- linux-2.6.orig/fs/xfs/linux-2.6/xfs_ioctl.c 2009-08-15 20:15:14.379163976 -0300 +++ linux-2.6/fs/xfs/linux-2.6/xfs_ioctl.c 2009-08-15 21:19:19.342664224 -0300 @@ -1275,6 +1275,31 @@ xfs_ioc_getbmapx( return 0; } +STATIC int +xfs_ioc_trim( + struct xfs_mount *mp, + __uint32_t *argp) +{ + xfs_agnumber_t agno; + int error = 0; + __uint32_t minlen; + + if (!capable(CAP_SYS_ADMIN)) + return -EPERM; + if (get_user(minlen, argp)) + return -EFAULT; + + down_read(&mp->m_peraglock); + for (agno = 0; agno < mp->m_sb.sb_agcount; agno++) { + error = -xfs_trim_extents(mp, agno, minlen); + if (error) + break; + } + up_read(&mp->m_peraglock); + + return error; +} + /* * Note: some of the ioctl's return positive numbers as a * byte count indicating success, such as readlink_by_handle. @@ -1524,6 +1549,9 @@ xfs_file_ioctl( error = xfs_errortag_clearall(mp, 1); return -error; + case XFS_IOC_TRIM: + return xfs_ioc_trim(mp, arg); + default: return -ENOTTY; } Index: linux-2.6/fs/xfs/xfs_alloc.c =================================================================== --- linux-2.6.orig/fs/xfs/xfs_alloc.c 2009-08-15 20:11:00.791163409 -0300 +++ linux-2.6/fs/xfs/xfs_alloc.c 2009-08-15 21:40:16.226666638 -0300 @@ -2470,6 +2470,96 @@ error0: return error; } +STATIC int +xfs_trim_extent( + struct xfs_mount *mp, + xfs_agnumber_t agno, + xfs_agblock_t fbno, + xfs_extlen_t flen) +{ + xfs_daddr_t blkno = XFS_AGB_TO_DADDR(mp, agno, fbno); + sector_t nblks = XFS_FSB_TO_BB(mp, flen); + int error; + + xfs_fs_cmn_err(CE_NOTE, mp, "discarding sectors [0x%llx-0x%llx]", + blkno, nblks); + + error = -__blkdev_issue_discard(mp->m_ddev_targp->bt_bdev, + blkno, nblks, GFP_NOFS, 1); + if (error && error != EOPNOTSUPP) + xfs_fs_cmn_err(CE_NOTE, mp, "discard failed, error %d", error); + return error; +} + +/* + * Notify the underlying block device about our free extent map. + * + * This walks all free extents above a minimum threshold and notifies the + * underlying device that these blocks are unused.

The actual ioctl is compatible, just add the case XFS_IOC_TRIM: return xfs_ioc_trim(mp, arg); to xfs_file_compat_ioctl(). I'll add this to the next spin of the patch.

Hmm. That was kinda the reason why I didn't want to post stuff yet. In current mainline only MTD implements the prepare_discard_fn, and we'll need it implemented and working. I think Matthews patches should be sufficient, unless they have some ATA revision check to not issue the TRIM for your device.

Okay, I got Matthews patches updated onto 2.6.31, and fixed the incompatibilities between those and the XFS TRIM patch (from Christoph), plus a sector_t printk issue. My apologies for attachments, but I am attaching the updated Christoph patch, as well as my hacked-up forward-port of Matthew's patches. Not pretty, but they work. :) Now.. running Christoph's "xfs trim" on a 4.6GB mostly already-trimmed XFS partition gave this for the first time around: [ 25.961891] Filesystem "sdb3": discarding sectors [0xc558-0x102328] [ 27.814553] Filesystem "sdb3": discarding sectors [0x10ea78-0x10e688] [ 29.771218] Filesystem "sdb3": discarding sectors [0x21d120-0x10e860] [ 31.726444] Filesystem "sdb3": discarding sectors [0x32b9a0-0x10e860] [ 33.679023] Filesystem "sdb3": discarding sectors [0x43f220-0x109860] [ 35.629948] Filesystem "sdb3": discarding sectors [0x548aa0-0x10e860] [ 37.583142] Filesystem "sdb3": discarding sectors [0x657320-0x10e860] [ 39.531822] Filesystem "sdb3": discarding sectors [0x765ba0-0x10e860] Slow, but presumably thorough. Subsequent runs were equally slow. The problem is, it still issues TRIMs to the LLD one extent at a time.

Yeah. The new version should fix it. Here's a version with the small update that Eric suggested, any chance we could get this into 2.6.31 still? -- Subject: xfs: fix locking in xfs_iget_cache_hit From: Christoph Hellwig The locking in xfs_iget_cache_hit currently has numerous problems: - we clear the reclaim tag without i_flags_lock which protects modifications to it - we call inode_init_always which can sleep with pag_ici_lock held (this is oss.sgi.com BZ #819) - we acquire and drop i_flags_lock a lot and thus provide no consistency between the various flags we set/clear under it This patch fixes all that with a major revamp of the locking in the function. The new version acquires i_flags_lock early and only drops it once we need to call into inode_init_always or before calling xfs_ilock. This patch fixes a bug seen in the wild where we race modifying the reclaim tag.

Hi Tommy and sorry for dropping the ball on this, I didn't remember this mail anymore until I look for more reporters of the inode related problems. Current mainline (Linus' git as of today) has a lot of the fixes in this area, any chance I could trick you into trying it? Maybe including the debug patch below which adds a printk to that one culprit that I thing might remain: Also if it still happens any chance you could send output of the dmesg command instead of the syslog files? For some reason syslogd usually eats up some bits of kernel oops message..

buffers are released back to the buf_t =A0zone when they are done.
zone allocation / free is very fast so managing lists of "free" buffers doesn't make a lot of sense.

sorry my fault i was asking a= bout the pages these buffers point to? ....
I see them being pickd from= the device inode of the monted device...

The new version acquires i_flags_lock early and only drops it once we need to call into inode_init_always or before calling xfs_ilock. This patch fixes a bug seen in the wild where we race modifying the reclaim tag.

Looks like the only difference between the generic and the extN check routine is the addition of -f to the fsck command line. What about just introducing a _fsck_args similar to _mount_opts where filesystems can set their additional required mount options?

That would work, yeah, and would be result in far less code duplication in common.rc. I'll take a whack at it and resubmit.

I noticed that the active part of the log wraps around the physical end/start of the log which reminds of this fix: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d1afb678ce77b930334a8a640a05b8e68178a377 I remember that without this fix we were seeing ASSERTs in the log recovery code - unfortunately I don't remember exactly where but it could be from the same location you are getting the "bad clientid" error. When a log record wraps the end/start of the physical log we need to do two I/Os to read the log record in. This bug caused the second read to go to an incorrect location in the buffer which overwrote part of the first I/O and corrupted the log record.

All i can say is that the kernel compiles and runs. On my testbox I can't reproduce the fs crash, seems 2.6.29.4 is more stable than 2.6.30/31. I've tried Erics steps to reproduce for 2.6.30/31, tried stressing the nfs mount with iozone, tried recursive unpacking and removing eclipse (a lot of small files) and this in a lot of parallel tasks. Nothing triggers the bug. You know, if I can't reproduce it I can't say whether it is fixed or not. I'll update one server this week with the patched kernel and switch nfs on again, and wait then for the next crash. Hope that comes never.

We're currently using the very latest 2.6.30, unfortunately. We've distilled this into a reproducible environment with a stack of NFS + XFS to a local disk + automated sysrq 'b' reboots. We're working on getting this bundled up into a nice little package as a VirtualBox vm for your consumption. Please tell me if this is not desirable. Thanks very much again.

This first starts an asynchronous writeout of the range in generic_write_sync, then calls into ->fsync which waits for all I/O on the file to finish, then forces the log inside xfs_fsync, then waits for the range again in generic_write_sync, and after this code calls into xfs_write_sync_logforce which forces to log _again_. We should be fine just doing your new filemap_fdatawrite_range helper here and let xfs_write_sync_logforce do the work. Long term we should just get rid of this stupid submit writes before syncing the iode, then wait crap which is a pain for all modern filesystems.

That's not only counter-intuitive because inode_init_always did not allocate the inode structure, but in case of XFS it's actively harmful as ->destroy_inode might delete the inode from a radix-tree that has never been added. This in turn might end up deleting the inode for the same inum that has been instanciated by another process and cause lots of cause subtile problems. Also in the case of re-initializing a reclaimable inode in XFS it would free an inode we still want to keep alive. backport of upstream commit 54e346215e4fe2ca8c94c54e546cc61902060510 Signed-off-by: Christoph Hellwig Reviewed-by: Eric Sandeen Index: linux-2.6/fs/inode.c =================================================================== --- linux-2.6.orig/fs/inode.c 2009-08-15 22:27:03.922699982 -0300 +++ linux-2.6/fs/inode.c 2009-08-15 22:27:13.274661514 -0300 @@ -118,12 +118,11 @@ static void wake_up_inode(struct inode * * These are initializations that need to be done on every inode * allocation as the fields are not initialised by slab allocation. */ -struct inode *inode_init_always(struct super_block *sb, struct inode *inode) +int inode_init_always(struct super_block *sb, struct inode *inode) { static const struct address_space_operations empty_aops; static struct inode_operations empty_iops; static const struct file_operations empty_fops; - struct address_space *const mapping = &inode->i_data; inode->i_sb = sb; @@ -150,7 +149,7 @@ struct inode *inode_init_always(struct s inode->dirtied_when = 0; if (security_inode_alloc(inode)) - goto out_free_inode; + goto out; /* allocate and initialize an i_integrity */ if (ima_inode_alloc(inode)) @@ -189,16 +188,12 @@ struct inode *inode_init_always(struct s inode->i_private = NULL; inode->i_mapping = mapping; - return inode; + return 0; out_free_security: security_inode_free(inode); -out_free_inode: - if (inode->i_sb->s_op->destroy_inode) - inode->i_sb->s_op->destroy_inode(inode); - else - kmem_cache_free(inode_cachep, (inode)); - return NULL; +out: + return -ENOMEM; } EXPORT_SYMBOL(inode_init_always); @@ -211,9 +206,18 @@ static struct inode *alloc_inode(struct else inode = kmem_cache_alloc(inode_cachep, GFP_KERNEL); - if (inode) - return inode_init_always(sb, inode); - return NULL; + if (!inode) + return NULL; + + if (unlikely(inode_init_always(sb, inode))) { + if (inode->i_sb->s_op->destroy_inode) + inode->i_sb->s_op->destroy_inode(inode); + else + kmem_cache_free(inode_cachep, inode); + return NULL; + } + + return inode; } void destroy_inode(struct inode *inode) Index: linux-2.6/fs/xfs/xfs_iget.c =================================================================== --- linux-2.6.orig/fs/xfs/xfs_iget.c 2009-08-15 22:27:04.378664366 -0300 +++ linux-2.6/fs/xfs/xfs_iget.c 2009-08-15 22:27:13.274661514 -0300 @@ -63,6 +63,10 @@ xfs_inode_alloc( ip = kmem_zone_alloc(xfs_inode_zone, KM_SLEEP); if (!ip) return NULL; + if (inode_init_always(mp->m_super, VFS_I(ip))) { + kmem_zone_free(xfs_inode_zone, ip); + return NULL; + } ASSERT(atomic_read(&ip->i_iocount) == 0); ASSERT(atomic_read(&ip->i_pincount) == 0); @@ -104,17 +108,6 @@ xfs_inode_alloc( #ifdef XFS_DIR2_TRACE ip->i_dir_trace = ktrace_alloc(XFS_DIR2_KTRACE_SIZE, KM_NOFS); #endif - /* - * Now initialise the VFS inode.

[...] A general interface design question: you added a new ioctl XFS_IOC_TRIM case. It's a sub-case of an ugly-looking demultiplexing xfs_file_ioctl(). What is your threshold for turning something into a syscall? When are ioctls acceptable in your opinion? I'm asking this because we are facing a similar problem with perfcounters: we need to extend the ioctl functionality there but introducing a new syscall looks wasteful. So i'm torn about the 'syscall versus ioctl' issue, i'd like to avoid making interface design mistakes and i'd like to solicit some opinions about this. I've attached the perfcounters ioctl patch below.

Do not add an syscall that is just another multiplexer without structure. Most likely it will just be even worse than sys_ioctl. Also really don't bother adding a system call that is specific to one singler driver or filesystem. Besides horrible logistics - you'd need some always built-in stub calling out to the possibly modular drivers/filesystem - it also simply doesn't make any semantical sense. I can't say I like the ioctl use in perfcounters much, but adding a special syscalls instead would be even more horrible. As for the trim support this really just was an RFC to start bringing some code into play instead of the endless masturbation about hat code that doesn't exist happens on hardware most people don't have. The interface will most ceetainly change and I hope we will have a common interface for all filesystems (or at least those that care).

One clear defined purpose which comes to mind is a "trim" or "punch" system call, for making holes in files as well as trimming block devices. Several other OSes have that capability on files. I don't remember - does TRIM guarantee the blocks read zeros afterwards? It would be tidy if it does, as it could have the same meaning with files. -- Jamie From liml@rtr.ca Wed Aug 19 20:38:07 2009 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-2.8 required=5.0 tests=AWL,BAYES_00 autolearn=ham version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7K1blBA241910 for ; Wed, 19 Aug 2009 20:37:57 -0500 X-ASG-Debug-ID: 1250732308-68ca00b70000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mail.rtr.ca (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 8DBC53E373D for ; Wed, 19 Aug 2009 18:38:29 -0700 (PDT) Received: from mail.rtr.ca (rtr.ca [76.10.145.34]) by cuda.sgi.com with ESMTP id sW9IPvGfQM11BXCP for ; Wed, 19 Aug 2009 18:38:29 -0700 (PDT) Received: by mail.rtr.ca (Postfix, from userid 1002) id 98A08B802F2; Wed, 19 Aug 2009 21:38:27 -0400 (EDT) Received: from [10.0.0.6] (corey.localnet [10.0.0.6]) by mail.rtr.ca (Postfix) with ESMTP id 38F5CB802F0; Wed, 19 Aug 2009 21:38:27 -0400 (EDT) Message-ID: <4A8CA913.7020902@rtr.ca> Date: Wed, 19 Aug 2009 21:38:27 -0400 From: Mark Lord Organization: Real-Time Remedies Inc.

Both ATA and SCSI leave it up to the device to decide whether reads after a trim on a logical block are determinate (i.e. zeroes are returned) or indeterminate. In the case of ATA the IDENTIFY DEVICE data word 69 bit 14 gives the indication. In the case of SCSI the READ CAPACITY(16) command response TPRZ bit gives the indication. In both case a value of one indicates determinate.

I was just doing the straightforward conversion and sync_page_range() essentially did what generic_write_sync() does since it called fdatawrite(), write_inode_now(inode, 1) (here XFS was forced to wait for pages and force the log), fdatawait().

Yes, that would be a correct behavior but I see no good way of doing that. Flushing on EIOCBQUEUED mostly works for simple filesystems like ext[23] where we don't do anything from end_io callback. The only risk is if we crash after the transaction commits but before the direct IO is done (we could expose stale data) but I'm not sure that is an issue with real HW. Anyway, the question is what we should do about it. For now, I'd call generic_write_sync() even in case EIOCBQUEUED is returned to preserve old behavior (EIOCBQUEUED does not seem to be returned from buffered write path so we really just preserve the old behavior). > > @@ -2343,16 +2328,6 @@ generic_file_buffered_write(struct kiocb *iocb, const struct iovec *iov, > > if (likely(status >= 0)) { > > written += status; > > *ppos = pos + status; > > - > > - /* > > - * For now, when the user asks for O_SYNC, we'll actually give > > - * O_DSYNC > > - */ > > - if (unlikely((file->f_flags & O_SYNC) || IS_SYNC(inode))) { > > - if (!a_ops->writepage || !is_sync_kiocb(iocb)) > > - status = generic_osync_inode(inode, mapping, > > - OSYNC_METADATA|OSYNC_DATA); > > - } > > } > > No problem with -EIOCBQUEUED here, but we change from doing > generic_osync_inode with OSYNC_DATA which does a full writeout of the > data to sync_page_range which only does the range writeout here.

Well, that's a bit drastic. But the RAID software should at least not issue TRIM commands in ignorance of such. Would it still be okay to do the TRIMs when the entire parity stripe (across all members) is being discarded?

So a fully discarded stripe still has to verify OK (as in what's read for the parity must match what's read for the data). All of this is the reason for the TPRZ bit for SCSI UNMAP ... and why WRITE_SAME is also under consideration for discards in T10.

A closer reading of d2015r2-ATAATAPI_Command_Set_-_2_ACS-2.pdf section 7.10.3.2 (latest ACS-2 draft from www.t13.org) shows that there are 3 possible variants for data read from a logical block that has been trimmed (or "unmapped"): a) indeterminate b) determinate c) determinate, return all zeroes In the case of b) the same data is returned for each subsequent read. And that data must not be something that has previously be written to some other LBA! In the case of SCSI (sbc3r19.pdf) case b) is not supported (very sensibly IMO). Another difference I noticed between SCSI and ATA drafts is with the SECURITY ERASE UNIT command which is somewhat similar to the SCSI FORMAT UNIT command (which includes a security erase option). The ATA draft says that all blocks are determinate ("mapped" in the SCSI state model) after a SECURITY ERASE UNIT. The SCSI draft says that all logical blocks may be unmapped after FORMAT UNIT.

When drive write caches lose power it may lead to inconsistencies in a journaling filesystem like xfs, which relies on data hitting the disk in a certain order, more or less. By default xfs issues barriers to enforce this ordering; this has the effect of flushing the write cache to make it safe. In some cases disabling barriers and also disabling write cache may be a good choice. If you "never" lose power (good ups?) then write caching is safe even w/o barriers. -Eric > Thank you! > From eike-kernel@sf-tec.de Thu Aug 20 10:43:34 2009 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: X-Spam-Status: No, score=-1.6 required=5.0 tests=BAYES_00,RCVD_IN_BRBL autolearn=no version=3.3.0-rupdated Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7KFhEqX104501 for ; Thu, 20 Aug 2009 10:43:24 -0500 X-ASG-Debug-ID: 1250783039-116f01a20000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mail.sf-mail.de (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 66D0514F98F4 for ; Thu, 20 Aug 2009 08:43:59 -0700 (PDT) Received: from mail.sf-mail.de (mail.sf-mail.de [62.27.20.61]) by cuda.sgi.com with ESMTP id AB11ONVaWWj7Pb3o for ; Thu, 20 Aug 2009 08:43:59 -0700 (PDT) Received: (qmail 15566 invoked from network); 20 Aug 2009 15:43:52 -0000 Received: from mnhm-5f74fb0d.pool.einsundeins.de ([::ffff:95.116.251.13] HELO donald.sf-tec.de) (auth=eike-kernel@sf-tec.de) by mail.sf-mail.de (Qsmtpd 0.12svn) with (DHE-RSA-AES256-SHA encrypted) ESMTPSA for ; Thu, 20 Aug 2009 17:43:52 +0200 From: Rolf Eike Beer To: Mark Lord X-ASG-Orig-Subj: Re: [PATCH, RFC] xfs: batched discard support Subject: Re: [PATCH, RFC] xfs: batched discard support Date: Thu, 20 Aug 2009 17:43:41 +0200 User-Agent: KMail/1.12.0 (Linux/2.6.31-rc6-git; KDE/4.3.0; i686; ; ) Cc: Ric Wheeler , Ingo Molnar , Christoph Hellwig , Peter Zijlstra , Paul Mackerras , Linus Torvalds , xfs@oss.sgi.com, linux-fsdevel@vger.kernel.org, linux-scsi@vger.kernel.org, linux-kernel@vger.kernel.org, jens.axboe@oracle.com, "IDE/ATA development list" , Neil Brown References: <20090816004705.GA7347@infradead.org> <4A8D5442.1000302@redhat.com> <4A8D5FDB.7080505@rtr.ca> In-Reply-To: <4A8D5FDB.7080505@rtr.ca> MIME-Version: 1.0 Content-Type: multipart/signed; boundary="nextPart1495252.XOLBvpv6Aq"; protocol="application/pgp-signature"; micalg=pgp-sha1 Content-Transfer-Encoding: 7bit Message-Id: <200908201743.50167.eike-kernel@sf-tec.de> X-Barracuda-Connect: mail.sf-mail.de[62.27.20.61] X-Barracuda-Start-Time: 1250783043 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 3.2.2.6739 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.60 COMMA_SUBJECT Subject is like 'Re: FDSDS, this is a subject' X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean --nextPart1495252.XOLBvpv6Aq Content-Type: Text/Plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Mark Lord wrote: > Ric Wheeler wrote: > > Note that returning consistent data is critical for devices that are > > used in a RAID group since you will need each RAID block that is used to > > compute the parity to continue to return the same data until you > > overwrite it with new data :-) > > > > If we have a device that does not support this (or is misconfigured not > > to do this), we should not use those devices in an MD group & do discard > > against it... > > .. > > Well, that's a bit drastic.

(As opposed to just partial > data there being dropped) I think there might be a related usecase that could benefit from=20 TRIM/UNMAP/whatever support in file systems even if the physical devices do= =20 not support that. I have a RAID5 at work with LVM over it. This week I dele= ted=20 an old logical volume of some 200GB that has been moved to a different volu= me=20 group, tomorrow I will start to replace all the disks in the raid with bigg= er=20 ones. So if the LVM told the raid "hey, this space is totally garbage from = now=20 on" the raid would not have to do any calculation when it has to rebuild th= at=20 but could simply write fixed patterns to all disks (e.g. 0 to first data, 0= to=20 second data and 0 as "0 xor 0" to parity). With the knowledge that some of = the=20 underlying devices would support "write all to zero" this operation could b= e=20 speed up even more, with "write all fixed pattern" every unused chunk would= go=20 down to a single write operation (per disk) on rebuild regardless which par= ity=20 algorithm is used. And even if things are in use the RAID can benefit from such things. If we= =20 just define that every unmapped space will always be 0 when read and I writ= e=20 to a raid volume and the other part of the checksum calculation is unmapped= =20 checksumming becomes easy as we already know half of the values before: 0. = So=20 we can save the reads from the second data stripe and most of the calculati= on. "dd if=3D/dev/md0" on an unmapped space is more or less the same as "dd=20 if=3D/dev/zero" than. I only fear that these things are too obviously as I would be the first to= =20 have this idea ;) Greetings, Eike --nextPart1495252.XOLBvpv6Aq Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (GNU/Linux) iEYEABECAAYFAkqNbzYACgkQXKSJPmm5/E5LNQCdFqJ/6Rb+l/1Jdd8GNwG86+MF g8sAmwXujLHOGE0WsLOAchKRWCzuayAG =PtAF -----END PGP SIGNATURE----- --nextPart1495252.XOLBvpv6Aq-- From ragepie@gmail.com Thu Aug 20 10:45:24 2009 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=ham version=3.3.0-rupdated Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7KFj3QS104623 for ; Thu, 20 Aug 2009 10:45:13 -0500 X-ASG-Debug-ID: 1250783143-15ac01a00000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mail-vw0-f107.google.com (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 5786414F992A for ; Thu, 20 Aug 2009 08:45:43 -0700 (PDT) Received: from mail-vw0-f107.google.com (mail-vw0-f107.google.com [209.85.212.107]) by cuda.sgi.com with ESMTP id 7QGJu20CUTEc7JTE for ; Thu, 20 Aug 2009 08:45:43 -0700 (PDT) Received: by vws5 with SMTP id 5so76274vws.32 for ; Thu, 20 Aug 2009 08:45:42 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=gamma; h=domainkey-signature:mime-version:received:in-reply-to:references :date:message-id:subject:from:to:cc:content-type :content-transfer-encoding; bh=ZRbHTMWkJiPLFiQ7pxyGztKvMpnj8sf++g/wLOa/PBU=; b=ZGnL15m99c4GJ0Ey6P7kHkAfgCkA523VT2/nwBivhsdLoH4x+VV1VYp0OO7Nucu5Z0 YR7QAVouJRoDxNM7sYwv3nAPOr+w0RVKR8PGFGYrsm9ed7sTBkTie9zRZJ5yZwTexW/R kgaYjqEA+K185y/Iv4qmbRVRlt93zs+g0sUlY= DomainKey-Signature: a=rsa-sha1; c=nofws; d=gmail.com; s=gamma; h=mime-version:in-reply-to:references:date:message-id:subject:from:to :cc:content-type:content-transfer-encoding; b=xZMUPkKi9VDSVTQXyse2BuhddFigSxCLVLr7CNB650gFN3pWWoJcRjzAFGZx4j8Kqr jZqMDbJYQO2UtC+LhcU8D74xhnhQAD4sFImOiLTQER7h9BqQjGm3v7ozchqkiU5hYpJQ UKfIZQffvyYgkcBfI+ERXrjYDQdV4z1jKQNPQ= MIME-Version: 1.0 Received: by 10.229.3.12 with SMTP id 12mr3219028qcl.98.1250783142357; Thu, 20 Aug 2009 08:45:42 -0700 (PDT) In-Reply-To: <4A8D6A6D.405@sandeen.net> References: <4A8D6A6D.405@sandeen.net> Date: Thu, 20 Aug 2009 11:45:42 -0400 Message-ID: X-ASG-Orig-Subj: Re: XFS Best Practices Subject: Re: XFS Best Practices From: Jeff Flowers To: Eric Sandeen Cc: xfs@oss.sgi.com Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable X-Barracuda-Connect: mail-vw0-f107.google.com[209.85.212.107] X-Barracuda-Start-Time: 1250783150 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 3.2.2.6739 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean On Thu, Aug 20, 2009 at 11:23 AM, Eric Sandeen wrote: > Jeff Flowers wrote: >> I am going to use XFS on a Arch Linux box and I am looking for ways to >> maximize XFS performance.

Sure, but the point is, if there is some all-encompassing "tweak" or optimization to be made, it is already a default in xfs. Tuning beyond defaults is usually about tradeoffs, and making those tradeoffs depends on what you actually want to do with the filesystem. It's not meant to be snarky, but by and large the defaults for xfs really do match most normal usage scenarios, and looking for tips & tweaks isn't usually necessary IMHO. >>> Also, I have seen a few people recommend turning off the internal >>> buffers of hard drives (via hdparm) when using a file system like XFS. >>> Good advice? >> When drive write caches lose power it may lead to inconsistencies in a >> journaling filesystem like xfs, which relies on data hitting the disk in >> a certain order, more or less.

After that we we do have stale data in the inode in the area not written yet. Is there some case between that simple filesystem and the i_size update from I/O completion handler in XFS/ext4 where this behaviour actually buys us anything? Any ext3 magic maybe?

If even a single sector is written to a "discarded" stripe, the entire stripe has to be written with determinate data that has the right parity. ie. Only full stripes can be discarded and only full-stripes can be put back in service.

There's two variants of multiplexing: - multiplex something rather straightforward and related - multiplex unrelated fields, data, structures I consider the second one 'ugly', the first one 'ok-ish'.

I'd like to understand the technical basis of your critisism and i'd like to address any deficiencies of the perfcounters code. You said you dont like the ioctl solution we have, but that you'd like a separate syscall even less. Perfcounters are a kernel-wide concept, encompassing 100% of all Linux installations, not just some special hardware. So by your own standard above they seem to be more than eligible for system calls (i hope i'm not mis-stating it), as long as they are cleanly structured. Yet you dont like the interface nor any future pushing of the currently ioctl bits of the interface into syscalls. Is there any other interface form you'd like more?

Any ext3 magic maybe? Hmm, I can imagine it would buy us something in two cases (but looking at the code, neither is implemented in such a way that it would really help us in any way): 1) when an inode and it's data are stored in one block (e.g. OCFS2 or UDF) do this. 2) when we journal data In the first case we would wait for block with data to be written only to submit it again because inode was still dirty. In the second case, it would make sence if we waited for transaction commit in fdatawait() because only then data is really on disk. But I don't know about a fs which would do it - ext3 in data=journal mode just adds page buffers to the current transaction in writepage and never sets PageWriteback so fdatawait() is nop for it. The page is pinned in memory only by the fact that its buffer heads are part of a transaction and thus cannot be freed.

Yes, probably. Actually, that's what UDF does. It's just that then the sequence fdatawrite(), fdatawait() does not really send the data to disk. But that probably does not matter.

The self-contained and reproducible environment can be downloaded from the following location: http://www.jquigley.com/tmp/xfsVM.tar.bz2 That's a ~550 MB (compressed) image that can be 'imported' directly into the latest VirtualBox. Instructions for setting up the environment (trivial, should take you a mere couple of minutes): http://www.jquigley.com/tmp/README.txt The basic concept here is to use the VM as the file server, accessing the XFS file system thereon through the guest OS which acts as the NFS client. Automated reboots are effected with cron and sysrq 'b', so you can just set this up and run it until failure. Hope this helps lend insight - if there are any questions, please ask.

Shu And using the loop device is kindof a worsened version of hanving write caches as we don't just have small disk caches that can fill up but major amounts of the main memory. The loop device before 2.6.30 is unfortunately not safe in case of system crashes. And given your other report we'll have to see if maybe the barrier support in 2.6.30 cause other kinds of problems to, although it could be something else.

The CI flag relaly only hcanges on thing in the on disk format, and that is the hash used for calculating the directory b+tree indices. So what you need to do is the following algorithm foreach diretory { read the whole directory structure into memory rewrite the btree with the case insensitive hash } handling of conflicts would be a pretty natural fallout of this, by checking for hash conflicts with the new case-sensitive flag.

That might certainly be more flexible than a whole disk as well if it is practical. Then as the 'attr' was set, the hash could be rebuilt either inplace, or created as a newdir with files being moved to the new dir.

Isn't it the best choice for most users given today's memory constraints (or lack thereof?) I saw a message about xfs parameter tuning and still see the mention to: 'logbufs=8,noatime' having to be specified on every mount. If the desire is to provide default optimal tuning, maybe a default of logbufs to 8 would be a good idea, and maybe a mkfs flag to default to 'noatime' and a 64MB internal log size would be good ideas for *most* users? How much of problem is defaulting to a 64MB internal log size when file partitions are measured in the 100GB range? I'm not sure how much use it is to even remember typing lazy-count=1 on the size partition each time. One more 'nit', while I think of it...for a 64MB log buffer size, one should be able to specify 32768b, but last I tried, that gave a 'too large' error...isn't 32768*4=64MB, not 32767b? What's really created when I use the 32767b max? 64MB or "64MB-4K"?

Taking it in the inode reclaim path means however that we can't take it while doing memory allocations that recurse back into the filesystem, and recently lockdep has been enhanced to find these cases and noticed quite a few of these in XFS. We had similar issues with the ilock, but we could get away with just stopping to do filesystem-recursing allocation under the ilock as there were just a few. The iolock is however taken over larger critical sections protection actual I/O and it's almost impossible to switch all these to NOFS allocations. Based on what the iolock is used for we don't actually need it in the reclaim path, though - at this point the inode is dead and no one has any other reference to it. See the listing in the first patch for a more detailed list of our current iolock holders and why they can't contend with the reclaim path. I would greatly appreciate some indepth-review of this to make sure I haven't missed a big loophole..

The i_lock mutex is taken in reclaim context so all allocations under it must avoid recursions into the filesystem. There are a couple more uses of xfs_buf_associate_memory in the log recovery code that are also affected by this, but I'd rather keep the code simple than passing on a gfp_mask argument. Longer term we should just stop requiring the memoery allocation in xlog_sync by some smaller rework of the buffer layer. Reported by the new reclaim context tracing in lockdep.

Taking it in the inode reclaim path means however that we can't take it while doing memory allocations that recurse back into the filesystem, and recently lockdep has been enhanced to find these cases and noticed quite a few of these in XFS. We had similar issues with the ilock, but we could get away with just stopping to do filesystem-recursing allocation under the ilock as there were just a few. The iolock is however taken over larger critical sections protection actual I/O and it's almost impossible to switch all these to NOFS allocations. Based on what the iolock is used for we don't actually need it in the reclaim path, though - at this point the inode is dead and no one has any other reference to it. See the listing in the first patch for a more detailed list of our current iolock holders and why they can't contend with the reclaim path.

As mention in the previous platch there is no need to acquire iolock in the inactive path as the inode is dead enough at that point. For release we can just acquire the lock in a non-blocking fashion. This will leave the pre-allocation on the file in case of lock contention, but we will still take care of it on the final iput.

Good catch, the two in xfs_dialloc should indeed be WANT_CORRUPTED_GOTOs. For the one in xfs_ialloc_next_rec. Below is the updated version of the patch, still needs to run through XFSQA again: Subject: xfs: untangle xfs_dialloc From: Christoph Hellwig Clarify the control flow in xfs_dialloc. Factor out a helper to go to the next node from the current one and improve the control flow by expanding composite if statements and using gotos. The xfs_ialloc_next_rec helper is borrowed from Dave Chinners dynamic allocation policy patches.

The root of the problem is some bad logic in the xfs_showargs() function, which is used to format the file system type-specific options in effect for a file system. The problem originated in this GIT commit: Move platform specific mount option parse out of core XFS code Date: 11/22/07 Author: Dave Chinner SHA1 ID: a67d7c5f5d25d0b13a4dfb182697135b014fa478 For XFS quotas, project and group quota management are mutually exclusive--only one can be in effect at a time. There are two parts to managing quotas: aggregating usage information; and enforcing limits. It is possible to have a quota in effect (aggregating usage) but not enforced. These features are recorded on an XFS mount point using these flags: XFS_PQUOTA_ACCT - Project quotas are aggregated XFS_GQUOTA_ACCT - Group quotas are aggregated XFS_OQUOTA_ENFD - Project/group quotas are enforced The code in error is in fs/xfs/linux-2.6/xfs_super.c: if (mp->m_qflags & (XFS_PQUOTA_ACCT|XFS_OQUOTA_ENFD)) seq_puts(m, "," MNTOPT_PRJQUOTA); else if (mp->m_qflags & XFS_PQUOTA_ACCT) seq_puts(m, "," MNTOPT_PQUOTANOENF); if (mp->m_qflags & (XFS_GQUOTA_ACCT|XFS_OQUOTA_ENFD)) seq_puts(m, "," MNTOPT_GRPQUOTA); else if (mp->m_qflags & XFS_GQUOTA_ACCT) seq_puts(m, "," MNTOPT_GQUOTANOENF); The problem is that XFS_OQUOTA_ENFD will be set in mp->m_qflags if either group or project quotas are enforced, and as a result both MNTOPT_PRJQUOTA and MNTOPT_GRPQUOTA will be shown as mount options.

It appears this could be the cause (no issues, as of yet). At this point it doesn't look crypto related anymore, but like some bad interaction between layers once we add those fsync in the loop code.

Unless the filesystems waits itself for the data to hit the disk like XFS or btrfs will be issue the cache flush potentially before the data write has actually reached the disk cache.

Except when the inode already is in the inode cache, in which case it returns the existing locked inode with increment lock recursion counts. Now, no one in the tree every decrements these lock recursion counts, so any user of this gets a potential double unlock when both the original owner of the inode and the xfs_trans_iget caller unlock it. When looking back in a git bisect in the historic XFS tree there was only one place that decremented these counts, xfs_trans_iput. Introduced in commit ca25df7a840f426eb566d52667b6950b92bb84b5 by Adam Sweeney in 1993, and removed in commit 19f899a3ab155ff6a49c0c79b06f2f61059afaf3 by Steve Lord in 2003. And as long as it didn't slip through git bisects cracks never actually used in that time frame. A quick audit of the callers of xfs_trans_iget shows that no caller really relies on this behaviour fortunately - xfs_ialloc allows this inode from disk so it must not be there before, and all the RT allocator routines only every add each RT bitmap inode once. In addition to removing lots of code and reducing the size of the inode item this patch also avoids the double inode cache lookup in each create/mkdir/mknod transaction.

Ok, this one failed the reality check - no matter how hard I tried I could not reproduce that case in my test harness. It turns out cache flush request are quite sensibly treated as barriers by the block layer and thus we drain the queue before issueing the cache flush.

Jan Kara has started unifying these two path for filesystems using the generic helpers, and I've started to look at XFS. The actual transaction commited by xfs_fsync and xfs_write_sync_logforce has a different transaction number, but actually is exactly the same. We'll only use the fsync transaction going forward. One major difference is that xfs_write_sync_logforce never issues a cache flush unless we commit a transaction causing that as a side-effect, which is an obvious bug in the O_SYNC handling. Second all the locking and i_update_size vs i_update_core changes from 978b7237123d007b9fa983af6e0e2fa8f97f9934 never made it to xfs_write_sync_logforce, so we add them back. To make xfs_fsync easily usable from the O_SYNC path, the filemap_fdatawait call is moved up to xfs_file_fsync, so that we don't wait on the whole file after we already waited for our portion in xfs_write. We'll also use a plain call to filemap_write_and_wait_range instead of the previous sync_page_rang which did it in two steps including an half-hearted inode write out that doesn't help us. Once we're done with this also remove the now useless i_update_size tracking.

We really need this notification because the VFS keeps writing directly into the inode structure instead of going through methods to update this state. In addition to the long-known atime issue we now also have a caller in VM code that updates c/mtime that way for shared writeable mmaps. And I found another one that no one has noticed in practice in the FIFO code. So implement ->dirty_inode to set i_update_core whenever the inode gets externally dirties, and switch the c/mtime handling to the same scheme we already use for atime (always picking up the value from the Linux inode). Note that this patch also removes the xfs_synchronize_atime call in xfs_reclaim - it was not only superflous (we'll never reclaim a dirty inode), but also didn't do anything (I_CLEAR is always set at this point). I replaced it with a myriad of ASSERTs for now to make my point. Also switch to just using file_update_time for regular reads/writes - that will get us all optimization done to it for free and make sure we notice early when it breaks.

There's really no reason to just do only either the submit or wait.

It still may happen; however, moving forward I was wondering.. If both '-o nobarrier' and the patch solves the issue, what is the next action that should be taken? Update the documentation to always use -o nobarrier for cryptoloop? Or get the patch reverted in mainline? Justin.

Replace the implementation with the one the kernel uses on these architectures. It might be a tad slower on architectures like x86, but I don't want to have multiple implementations around to not let the testing matrix explode. Also remove the unaligned.h header which includes another implementation for unaligned access we don't actually use anymore. Note that the little change to xfs_inode.c needs to go into the kernel aswell, I will send a patch for that shortly.

We'll have to figure out why it causes those problems and how fix them. -o nobarrier on a loop device is extremly unsafe as you will possible lose large amounts of log updates in case of a crash.

And it does the same things as xfs_iget() does, but in a more restricted context. One difference I see is that this verifies the transaction pointers match--and if they do not, it returns NULL. In xfs_iget(), meanwhile, there is no such check. I'm not familiar enough with the transaction code to know what circumstances that might lead a hashed inode without a matching transaction pointer, but thought I'd point it out anyway in hopes you maybe did... > - return ip; > -} > - > /* > * Decrement reference count of an inode structure and unlock it. > * . . . > Index: linux-2.6/fs/xfs/xfs_trans_inode.c > = =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D > --- linux-2.6.orig/fs/xfs/xfs_trans_inode.c 2009-08-26 = 14:15:45.689894519 -0300 > +++ linux-2.6/fs/xfs/xfs_trans_inode.c 2009-08-26 14:17:14.434495492 = -0300 . . . > @@ -163,8 +89,6 @@ xfs_trans_ijoin( > xfs_inode_item_init(ip, ip->i_mount); > iip =3D ip->i_itemp; > ASSERT(iip->ili_flags =3D=3D 0); > - ASSERT(iip->ili_ilock_recur =3D=3D 0); > - ASSERT(iip->ili_iolock_recur =3D=3D 0); These are the only other references, and (assuming we've done a lot of testing with ASSERT() enabled) it is evident that these are always zero at this point. In any case, what this means is that xfs_trans_ijoin() must never be called after xfs_trans_iget() has been called on a hashed inode. Again, I'm not familiar enough with how we manage transactions to to verify by inspection this is the case, but I presume it is.

What do people thing about pushing out a 3.0.3 xfsprogs release? Since 3.0.1 (discounting 3.0.2 as a Debian-only thing quickly following 3.0.1): we have the following changes the list below. It's not a whole lot, but everything is relatively small fixes, the the unaligned thing makes the 3.0 series so far unusable on strict alignment platforms. If we go for it I can update the CHANGES ASAP for the release, and ater that we can start putting in changes for a 3.1.0 release - I have Barry's repair speedups ready for a wider audience, Eric has the patch to make the lazy sb counters default and I can do the long needed resync with the kernel code.

I'm always happy about people actually looking deep into the code in reviews. Let's got through the above case in detail: To have i_tansp set the inode must be locked. So assuming we have an inode in a transaction that is not your. We will no go on to the xfs_iget once the xfs_inode_incore is gone. But as part of xfs_iget we will lock the inode exclusively, which means we have to wait until the other transaction unlocks the inode. Also if this was for some reason no true we would immediately hit the ASSERT in xfs_trans_ijoin which chcks that the i_transp pointer is NULL. > > xfs_inode_item_init(ip, ip->i_mount); > > iip = ip->i_itemp; > > ASSERT(iip->ili_flags == 0); > > - ASSERT(iip->ili_ilock_recur == 0); > > - ASSERT(iip->ili_iolock_recur == 0); > > These are the only other references, and (assuming we've done > a lot of testing with ASSERT() enabled) it is evident that > these are always zero at this point.

Not a big deal. the __ routines are internal implementation details, the kernel has non-__ prefixed versions that take void pointers, but I didn't bother to add them to xfsprogs as we only do unaligned access to 64bit values. That beeing said I dislike the interface taking void pointers as it removes important error checking. The actually visible interface should take __be16/32/64 types to enforce they are used on the right type. Once I get some time I will push for that in the kernel again, but for xfsprogs I really do want to stick to the kernel interfaces so that we can share the code unmodified.

The results should be int types: __be16, etc., I agree. But I'm saying the unaligned addresses--which we (now) make no assumptions about and treat as character pointers--I think the void pointer explicitly captures that unaligned quality (and avoids any need for a cast). In any event I think it's fine either way. Really not a big deal, just a tiny detail that only a geek could love to argue about. -Alex From felixb@sgi.com Fri Aug 28 17:48:49 2009 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 relay.sgi.com (relay2.corp.sgi.com [137.38.102.29]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7SMmTP1181785 for ; Fri, 28 Aug 2009 17:48:39 -0500 Received: from estes.americas.sgi.com (estes.americas.sgi.com [128.162.236.10]) by relay2.corp.sgi.com (Postfix) with ESMTP id CF3203040D1 for ; Fri, 28 Aug 2009 15:49:23 -0700 (PDT) Received: from eagdhcp-232-188.americas.sgi.com (eagdhcp-232-188.americas.sgi.com [128.162.232.188]) by estes.americas.sgi.com (Postfix) with ESMTP id 92ED77000103; Fri, 28 Aug 2009 17:49:23 -0500 (CDT) Cc: xfs@oss.sgi.com Message-Id: <6854DCEB-F9C8-4969-8012-65B0CD671E38@sgi.com> From: Felix Blyakher To: Christoph Hellwig In-Reply-To: <20090828221304.GA17666@infradead.org> Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 7bit Mime-Version: 1.0 (Apple Message framework v926) Subject: Re: [PATCH] xfsprogs: update CHANGES Date: Fri, 28 Aug 2009 17:49:22 -0500 References: <20090828221304.GA17666@infradead.org> X-Mailer: Apple Mail (2.926) X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean On Aug 28, 2009, at 5:13 PM, Christoph Hellwig wrote: > Signed-off-by: Christoph Hellwig Reviewed-by: Felix Blyakher I'll generate the 3.0.3 package later tonight.

Uh, that was the "/dev/md6 with 5 units", so I guess Elvis personally came to deliver an exact copy of drive #4, or else someone has invented a new algorithm to ensure that a RAID5 can lose 2 drives and still be fine.

[ ... ] Well, I am not at the level of those who can develop such an advanced understanding of storage systems that includes 19+1 arrays and RAID5s that can lose 2 drives and be "again OK". But I'd look at how many controllers and drives are actually still working by doing a read test of all the drives. Once that is known perhaps some recovery strategy can be discerned. If several drives have failed it might take several weeks or months or even years to do a partial recovery. If things are really very lucky only some of the 6 host adapters have failed, or only one drive per array, and replacing the host adapters will get things working again, except that running 'xfs_repair' on an incomplete array will have made things even better, more challenging and advanced.

An application could certainly be doing something that results in this sort of thing. w/o reading some kde code I can't say for sure, and I don't mean to blame KDE, but this isn't necessarily a bug in xfs. -Eric From michael.monnerie@is.it-management.at Sat Aug 29 17:14:09 2009 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,J_CHICKENPOX_33 autolearn=no version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7TMDnoI246278 for ; Sat, 29 Aug 2009 17:13:59 -0500 X-ASG-Debug-ID: 1251584073-298a00400000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mailsrv5.zmi.at (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id 7FCDE40D3B1 for ; Sat, 29 Aug 2009 15:14:34 -0700 (PDT) Received: from mailsrv5.zmi.at (mailsrv5.zmi.at [212.69.164.54]) by cuda.sgi.com with ESMTP id DnmvmLAySi67FGSS for ; Sat, 29 Aug 2009 15:14:34 -0700 (PDT) Received: from mailsrv.i.zmi.at (h081217106033.dyn.cm.kabsi.at [81.217.106.33]) (using TLSv1 with cipher DHE-RSA-CAMELLIA256-SHA (256/256 bits)) (Client CN "mailsrv2.i.zmi.at", Issuer "power4u.zmi.at" (not verified)) by mailsrv5.zmi.at (Postfix) with ESMTP id C15F66A1 for ; Sun, 30 Aug 2009 00:14:28 +0200 (CEST) Received: from saturn.localnet (saturn.i.zmi.at [10.72.27.2]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (Client did not present a certificate) by mailsrv.i.zmi.at (Postfix) with ESMTPSA id 503D040015E for ; Sun, 30 Aug 2009 00:14:28 +0200 (CEST) From: Michael Monnerie Organization: it-management http://it-management.at To: xfs@oss.sgi.com X-ASG-Orig-Subj: Re: xfs data loss Subject: Re: xfs data loss Date: Sun, 30 Aug 2009 00:14:13 +0200 User-Agent: KMail/1.10.3 (Linux/2.6.30.5-ZMI; KDE/4.1.3; x86_64; ; ) References: <4A981133.6060009@sandeen.net> In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Content-Disposition: inline Message-Id: <200908300014.13845@zmi.at> X-Barracuda-Connect: mailsrv5.zmi.at[212.69.164.54] X-Barracuda-Start-Time: 1251584076 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 3.2.2.7578 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean On Samstag 29 August 2009 Passerone, Daniele wrote: > But apart from that, it is not as easy to backup 20 TB, so we decided > to set it as data storage leaving the responsibilty of the backup to > our users. I do not consider it completely absurd. Right, if you communicated this to users it's OK. But really, don't create any RAID with more than 8 data disks. Performance doesn't increase above that, and the chance that a single disk dies is already 8x as high as with a single disk. I wish you luck with your recovery, but please try to split your 20 disks, make it 2x9 disks with a RAID-5, better RAID-6, and connect those two via RAID-0. So you get a RAID-50 or RAID-60. Take the remaining 2 drives as hot spare. This will protect you at least from drive failures, and speeds up recreating the RAID when a disk dies. Try to connect the disks which are in a single RAID-5/6 via the same controllers, so if a controller dies it's only one RAID-5/6 part that dies, which will help to make it possible to repair. mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0660 / 415 65 31 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: AC19 F9D5 36ED CD8A EF38 500E CE14 91F7 1C12 09B4 // Keyserver: wwwkeys.eu.pgp.net Key-ID: 1C1209B4 From michael.monnerie@is.it-management.at Sat Aug 29 17:17:31 2009 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,J_CHICKENPOX_33 autolearn=no version=3.3.0-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7TMHBar246446 for ; Sat, 29 Aug 2009 17:17:21 -0500 X-ASG-Debug-ID: 1251584272-317403a80000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mailsrv5.zmi.at (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id A10C640D3C3 for ; Sat, 29 Aug 2009 15:17:52 -0700 (PDT) Received: from mailsrv5.zmi.at (mailsrv5.zmi.at [212.69.164.54]) by cuda.sgi.com with ESMTP id HgEmHggC2BbHATqA for ; Sat, 29 Aug 2009 15:17:52 -0700 (PDT) Received: from mailsrv.i.zmi.at (h081217106033.dyn.cm.kabsi.at [81.217.106.33]) (using TLSv1 with cipher DHE-RSA-CAMELLIA256-SHA (256/256 bits)) (Client CN "mailsrv2.i.zmi.at", Issuer "power4u.zmi.at" (not verified)) by mailsrv5.zmi.at (Postfix) with ESMTP id 267926A1 for ; Sun, 30 Aug 2009 00:17:22 +0200 (CEST) Received: from saturn.localnet (saturn.i.zmi.at [10.72.27.2]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (Client did not present a certificate) by mailsrv.i.zmi.at (Postfix) with ESMTPSA id A550340015E for ; Sun, 30 Aug 2009 00:17:21 +0200 (CEST) From: Michael Monnerie Organization: it-management http://it-management.at To: xfs@oss.sgi.com X-ASG-Orig-Subj: Re: pushing out a new xfsprogs release, was Re: [PATCH] xfsprogs: fix unaligned access in libxfs Subject: Re: pushing out a new xfsprogs release, was Re: [PATCH] xfsprogs: fix unaligned access in libxfs Date: Sun, 30 Aug 2009 00:17:07 +0200 User-Agent: KMail/1.10.3 (Linux/2.6.30.5-ZMI; KDE/4.1.3; x86_64; ; ) References: <20090828153718.GA26409@infradead.org> <4A9810C7.8010806@sandeen.net> <20090828182454.GA8217@infradead.org> In-Reply-To: <20090828182454.GA8217@infradead.org> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Content-Disposition: inline Message-Id: <200908300017.07268@zmi.at> X-Barracuda-Connect: mailsrv5.zmi.at[212.69.164.54] X-Barracuda-Start-Time: 1251584279 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 3.2.2.7578 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean On Freitag 28 August 2009 Christoph Hellwig wrote: > What do people thing about pushing out a 3.0.3 xfsprogs > release?

I've never had that for reiserfs, so I guess it's really XFS to blame here. I like that filesystem, but such things really shouldn't happen. > however I am curious to see if you see any of the issues here: > http://forums.storagereview.net/index.php?showtopic=27303&hl=velociraptor > > Since you only use one drive and not a raid of the WD Velociraptors, > you may not be affected, but I was curious, thanks. In fact I use 3 VelociRaptor 150GB and 6 Raptors. 8 are in a single RAID-6 in a server running since about 3 years, and during this time 2 Raptors died and were replaced by VelociRaptors. The one I use in my desktop is a spare spart to use in case the server needs one. I just use it because the speed is nice, and I see if it has failures. Smartctl is running as a daemon here, so you can see the SMART self tests. It's almost definitely not the drive. mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0660 / 415 65 31 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: AC19 F9D5 36ED CD8A EF38 500E CE14 91F7 1C12 09B4 // Keyserver: wwwkeys.eu.pgp.net Key-ID: 1C1209B4 From michael.monnerie@is.it-management.at Sun Aug 30 03:44:28 2009 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,J_CHICKENPOX_33 autolearn=no version=3.3.0-rupdated Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7U8i8S2014373 for ; Sun, 30 Aug 2009 03:44:18 -0500 X-ASG-Debug-ID: 1251621894-424b00150000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from mailsrv5.zmi.at (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with ESMTP id E59EF1B83D22 for ; Sun, 30 Aug 2009 01:44:54 -0700 (PDT) Received: from mailsrv5.zmi.at (mailsrv5.zmi.at [212.69.164.54]) by cuda.sgi.com with ESMTP id P0eLkEcJZ1SGhWRW for ; Sun, 30 Aug 2009 01:44:54 -0700 (PDT) Received: from mailsrv.i.zmi.at (h081217106033.dyn.cm.kabsi.at [81.217.106.33]) (using TLSv1 with cipher DHE-RSA-CAMELLIA256-SHA (256/256 bits)) (Client CN "mailsrv2.i.zmi.at", Issuer "power4u.zmi.at" (not verified)) by mailsrv5.zmi.at (Postfix) with ESMTP id 9295C3D1 for ; Sun, 30 Aug 2009 10:44:23 +0200 (CEST) Received: from saturn.localnet (saturn.i.zmi.at [10.72.27.2]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (Client did not present a certificate) by mailsrv.i.zmi.at (Postfix) with ESMTPSA id 5386940015E for ; Sun, 30 Aug 2009 10:44:23 +0200 (CEST) From: Michael Monnerie Organization: it-management http://it-management.at To: xfs@oss.sgi.com X-ASG-Orig-Subj: Re: pushing out a new xfsprogs release, was Re: [PATCH] xfsprogs: fix unaligned access in libxfs Subject: Re: pushing out a new xfsprogs release, was Re: [PATCH] xfsprogs: fix unaligned access in libxfs Date: Sun, 30 Aug 2009 10:44:03 +0200 User-Agent: KMail/1.10.3 (Linux/2.6.30.5-ZMI; KDE/4.1.3; x86_64; ; ) References: <20090828153718.GA26409@infradead.org> <200908300017.07268@zmi.at> <4A99D43D.5050208@sandeen.net> In-Reply-To: <4A99D43D.5050208@sandeen.net> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline Message-Id: <200908301044.03807@zmi.at> X-Barracuda-Connect: mailsrv5.zmi.at[212.69.164.54] X-Barracuda-Start-Time: 1251621902 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 3.2.2.7619 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean On Sonntag 30 August 2009 Eric Sandeen wrote: > Afraid I haven't fixed that one yet, sorry. =A0If you could open a bug > on xfs.org's bugzilla it'd be much better for tracking ...

If I've guessed right what that code does, proper O_RSYNC will be easy: int generic_sync_before_read(struct file *file, loff_t pos, loff_t count) { int is_sync = ((file->f_flags & O_SYNC) || IS_SYNC(file->f_mapping->host)); int is_dsync = is_sync || (file->f_flags & O_DSYNC); if (!is_dsync || !(file->f_flags & O_RSYNC)) return 0; return vfs_fsync_range(file, file->f_ath.denty, pos, pos + count - 1, is_sync); } (By the way, did I mention Irix has range-fsync and range-fdatasync system calls too :-) (actually fcntls)) -- Jamie From hch@lst.de Sun Aug 30 11:39:34 2009 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) 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-rupdated Received: from cuda.sgi.com (cuda2.sgi.com [192.48.176.25]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7UGd9Lk036101 for ; Sun, 30 Aug 2009 11:39:24 -0500 X-ASG-Debug-ID: 1251650403-36a0019a0000-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 999DE40E6F3; Sun, 30 Aug 2009 09:40:04 -0700 (PDT) Received: from verein.lst.de (verein.lst.de [213.95.11.210]) by cuda.sgi.com with ESMTP id uEXTqZGLT1kMbmYe; Sun, 30 Aug 2009 09:40:04 -0700 (PDT) X-ASG-Whitelist: Client 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 n7UGdHVL024402 (version=TLSv1/SSLv3 cipher=EDH-RSA-DES-CBC3-SHA bits=168 verify=NO); Sun, 30 Aug 2009 18:39:17 +0200 Received: (from hch@localhost) by verein.lst.de (8.12.3/8.12.3/Debian-7.2) id n7UGdHri024401; Sun, 30 Aug 2009 18:39:17 +0200 Date: Sun, 30 Aug 2009 18:39:17 +0200 From: Christoph Hellwig To: Jamie Lokier Cc: Christoph Hellwig , Jan Kara , LKML , hch@lst.de, linux-fsdevel@vger.kernel.org, Evgeniy Polyakov , ocfs2-devel@oss.oracle.com, Joel Becker , Felix Blyakher , xfs@oss.sgi.com, Anton Altaparmakov , linux-ntfs-dev@lists.sourceforge.net, OGAWA Hirofumi , linux-ext4@vger.kernel.org, tytso@mit.edu X-ASG-Orig-Subj: Re: [PATCH 07/17] vfs: Introduce new helpers for syncing after writing to O_SYNC file or IS_SYNC inode Subject: Re: [PATCH 07/17] vfs: Introduce new helpers for syncing after writing to O_SYNC file or IS_SYNC inode Message-ID: <20090830163917.GA23955@lst.de> References: <1250875447-15622-1-git-send-email-jack@suse.cz> <1250875447-15622-8-git-send-email-jack@suse.cz> <20090827173540.GA19115@infradead.org> <20090830163551.GA7129@shareable.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: <20090830163551.GA7129@shareable.org> 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: 1251650404 X-Barracuda-Virus-Scanned: by cuda.sgi.com at sgi.com X-Virus-Scanned: ClamAV version 0.94.2, clamav-milter version 0.94.2 on oss.sgi.com X-Virus-Status: Clean On Sun, Aug 30, 2009 at 05:35:51PM +0100, Jamie Lokier wrote: > I like that.

I'm not sure if that's a good idea or if we should just add a sys_fdatasync_rage systems call. I don't quite see the point of a range-fsync, but it could be easily implemented as a flag.

Apart from the way it loses your data, the man page for sync_file_range never manages to explain quite why you should use the existing flags in various combinations. It's only obvious if you've worked on a kernel yourself. Having asked this before, it appears one of the reasons for sync_file_range working as it does is to give the application more control over writeback order and to some extent, reduce the amount of blocking. But it's really difficult to manage the amount of blocking with it. You need to know the request queue size among other things, and even if you do it's dynamic. Writeback order would be as easy with fdatasync_range, and if you want to reduce blocking, a good implementation of aio_fsync would be more useful. Or, you have to use application writeback threads anyway, so fdatasync_range again. The one thing sync_file_range can do is let you submit multiple ranges which the elevators can sort for the hardware. You can't do that with sequential calls to fdatasync_range, and it's not clear that aio_fsync is implemented well enough (but it's a fairly good API for it). Nick Piggin's idea to let fdatasync_range take multiple ranges might help with that, but it's not clear how much. > I'm not sure if that's a good > idea or if we should just add a sys_fdatasync_rage systems call. fdatasync_range has the advantage of being comprehensible. People will use it because it makes sense. sync_file_range could be hijacked with new flags to implement fdatasync_range. If that's done, I'd rename the system call, but keep it compatible with sync_file_range's flags, which would never be set when userspace uses the new functionality. > I don't quite see the point of a range-fsync, but it could be easily > implemented as a flag. A flags argument would be good anyway: to indicate if we want an ordinary fdatasync, or something which flushes the relevant bit of volatile hardware caches too. With that as a capability, it is useful to offer fsync, because that'd be the only way to get a volatile hardware cache flush (or maybe the only way not to?). For that reason, it should be permitted to give an infinitely large range. I don't see the point of range-fsync either, but I'm not sure if I see any harm in it. If permitted, range-fsync with a zero-byte range would flush just the inode state and none of the data. If that's technically available, maybe O_ISYNC and "#define O_SYNC (O_DATASYNC|O_ISYNC)" isn't such as daft idea. I'd call it fsync_range for consistency with aio_fsync (POSIX), which takes flags O_DSYNC or O_SYNC to indicate the type of sync. But I'd use new flag names, to keep the space clear for other flags. Just sketching some ideas: /* One of FSYNC_RANGE_SYNC or FSYNC_RANGE_DATASYNC must be set. */ #define FSYNC_RANGE_SYNC (1 << 0) /* Like fsync, O_SYNC. */ #define FSYNC_RANGE_DATASYNC (1 << 1) /* Like fdatasync, O_DSYNC. */ #define FSYNC_RANGE_NO_HWCACHE (1 << 2) /* Not hardware caches. */ -- Jamie From dmfforg@yahoo.fr Sun Aug 30 13:42:03 2009 X-Spam-Checker-Version: SpamAssassin 3.3.0-rupdated (updated) on oss.sgi.com X-Spam-Level: *** X-Spam-Status: No, score=3.0 required=5.0 tests=BAYES_50,HTML_MESSAGE autolearn=no version=3.3.0-rupdated Received: from cuda.sgi.com (cuda3.sgi.com [192.48.176.15]) by oss.sgi.com (8.14.3/8.14.3/SuSE Linux 0.8) with ESMTP id n7UIfgue041566 for ; Sun, 30 Aug 2009 13:41:53 -0500 X-ASG-Debug-ID: 1251657724-1c2901a60000-NocioJ X-Barracuda-URL: http://cuda.sgi.com:80/cgi-bin/mark.cgi Received: from web24705.mail.ird.yahoo.com (localhost [127.0.0.1]) by cuda.sgi.com (Spam Firewall) with SMTP id 7480C158919B for ; Sun, 30 Aug 2009 11:42:04 -0700 (PDT) Received: from web24705.mail.ird.yahoo.com (web24705.mail.ird.yahoo.com [212.82.104.178]) by cuda.sgi.com with SMTP id YmOQKeiFND8SzECJ for ; Sun, 30 Aug 2009 11:42:04 -0700 (PDT) Received: (qmail 8675 invoked by uid 60001); 30 Aug 2009 18:42:04 -0000 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=yahoo.fr; s=s1024; t=1251657724; bh=ZZAF4qg8A2t4e++JxvofZmxOjPvravAavEuSMiRRObQ=; h=Message-ID:X-YMail-OSG:Received:X-Mailer:Date:From:Subject:To:MIME-Version:Content-Type; b=QJ66h59HfXVtcsDAbcEoDgH5H+AQNZRxx6D+Kd0DEfKhiXKG+NdwXBW4jZuwpDWsziNu16ZQb7pdldZkq3ReRsZnZUDcn0Vwzf5NalYsV1iXlBuKphFDCze6li5MVY0vx1AMCApBDujg4pIZ/CuQyMyMZ+QTZG6FwZmt8v6tqHk= DomainKey-Signature:a=rsa-sha1; q=dns; c=nofws; s=s1024; d=yahoo.fr; h=Message-ID:X-YMail-OSG:Received:X-Mailer:Date:From:Subject:To:MIME-Version:Content-Type; b=5xChAePJiRZqs0CWstzB9v4nqhX/Nm4aq6Fd0/Z86I+q8tLaGEp8sW4o2hdORQNcq1CIXxlOaUI+zURZ+eeXImCxE7LI3SDebjpyH1R84+pWy7gJgGOxxhJ6ZqDl3WoqpkE90AJZo/y1qC4uhoxeJre/iSL5Jlr6n5eXIETjpCI=; Message-ID: <360342.8213.qm@web24705.mail.ird.yahoo.com> X-YMail-OSG: VxhHL6wVM1m.moC0zg4ri.X6418YEl.PxWJUTXb6d9OD9Vg_SIVDRLztI9zb9sXDPtfN9EV6UPAARA9oA0kCbNFwb_jttSh9gUmnw_Lm3pa5HaGRMEol1zcXzPmPElTNDt1lGUfXK1SaPkgmgqI8yB.UqEPUZ4udPzWQWgbbWk1CO227ql40LgTQHZadYkwuQjRrBjf1YyknRXBpS_L1stdWnxbX30cCyI8bha7D55xi7voegtUCSd_jKQTBi_WwkDK9QtuEhuA6BRoTHzMVCxUjwHm5OA-- Received: from [63.247.87.103] by web24705.mail.ird.yahoo.com via HTTP; Sun, 30 Aug 2009 18:42:04 GMT X-Mailer: YahooMailClassic/6.1.2 YahooMailWebService/0.7.338.2 Date: Sun, 30 Aug 2009 18:42:04 +0000 (GMT) From: Dikembe Mutombo X-ASG-Orig-Subj: Dikembe Mutombo FOUNDATION.

The new named storage market has taken off to drive the whole business and marketing strategies. Shortly, the tota= l global production volume of Blu-ray Disc has reached to 30 million pieces b= y 2008. While the unit price of Blu-ray Disc has rapidly slid down to US$ 2 o= r $3, the Blu-ray Disc Association (BDA) has estimated a significant climb of total production volume to achieve 152 million disks by 2010. This figure i= s expected to generate more than 280 million Blu-ray Discs in 2011 as well. With such a huge business potential as well as prospective high-definition entertainment market ahead, the Asian biggest and global leading ICT exhibition - COMPUTEX TAIPEI - is the must-visit platform to picture the latest digital storage media trends and developments. *Strong Taiwan BD Supply Chain* Looking back to COMPUTEX TAIPEI 2009, we have seen quite some Taiwan suppliers showcase numerous Blu-ray products. Among all, RITEK and CMC both represented the latest Blu-ray Discs product ranges at the show ground. RITEK has also announced to launch its BDA certified 50GB Blu-ray Disc in the second year of 2009. Apart from some Japanese companies, RITEK is not only the first manufacturer in Asia who has the capability of supplying BDA standard Blu-ray Disc, but also the only permitted disc provider in Taiwan. Meanwhile, two of the top three BD player manufacturers including Hitachi L= G Data Storage (HLDS) and Philips & Lite-On Digital Solutions Corporation (PLDS) also introduced 4X BD Slim serial and 8X BD Combo to grab the market attention. Lite-On, who has cooperated with Philips, is expected to benefit from BD patent cost with better price advantage in the long run. Quanta Storage Inc (QSI), however, has to relay on its mother company Quanta Computer Group to maintain its global No. 1 NB supplier status to deliver stable BD demand. While key components such as chipset and spindle motor account for more tha= n 25% of total cost in the whole process of BD player manufacturing, Taiwan suppliers who have advantages in cost control as well as flexible productio= n line are expected to become the key force to increase new product adoption rate with affordable price in the end market. Companies who have involved i= n BD technologies and innovations are chipset pioneers Mediatek and Sunext Technology; spindle motor supplier Delta; BD player providers QSI, BenQ, PLDS, ASUS; disc manufacturers RITEK, CMC, Daxon as well as software developer Cyberlink. The complete supplier chain in Taiwan means lower cost in BD hardware and software too. *Taiwan** Suppliers in BD Industry* ** Source: Topology Research Institute, 2009/8 *Otaku Economy to Accelerate Future Growth* The global financial storm has deeply impacted the overall purchasing power in every sector.

Following the step of Sony in 2008; Sharp, Panasonic and Pioneer also launched a variety of entry-level options with the price ranging from 30,000 to 50,000 Japanese Yen by 2009. Nevertheless, high-end BD Player such as the forth generation Pioneer BD Player with the highest 48bit Deep Color technology will also be announced in the third season of 2009. The price of this top model is therefore between 50,000 and 80,000 Japanese Yen. Researches also indicated that more than half of consumers in Japan have shifted to BD formats.

Damn. I rebooted to 2.6.27 to test something unrelated, forgot about it, and later tried xfs_growfs -d, which failed as per above. And yes indeed, in 2.6.30 everything works as expected.

The copat ioctls were added in > 2.6.28. On a slightly related note: I also have a system with a 32bit userland and a 64bit kernel. After switching to the 64bit kernel, xfs_fsr was no longer working, but that was caused by the then still missing compat ioctls. Today I retried it, but it still fails: XFS_IOC_SWAPEXT failed: ino=: Invalid argument Looking at the compat code SWAPEXT looks somewhat suspicious: fs/xfs/linux-2.6/xfs_ioctl32.h defines XFS_IOC_SWAPEXT_32, but I can't find a single place where this is used. And in the big switch of xfs_compat_ioctl() the value XFS_IOC_SWAPEXT is surrounded by contants that all end in 32. I don't have any experience with the linux ioctl code, I only read fs/xfs/linux-2.6/xfs_ioctl32.c, but for my untrained eye it looks like there is a _32 missing. Or am I misreading this completely?

Then 'mount' with '-o sync', or write your own applications and patches to the GNU/Linux kernel to enforce well known atomicity and persistence semantics. This issue as related to several filesystems has been discussed in great depth over the past several months.

Unfortunately KDE like most applications is known not to do the right thing (depending on specific app and version, but most IIRC).
