From adilger at sun.com Thu Jan 17 18:35:41 2008 From: adilger at sun.com (Andreas Dilger) Date: Thu, 17 Jan 2008 11:35:41 -0700 Subject: [Lustre-announce] [URGENT] Lustre 1.6.4.1 data loss bug Message-ID: <20080117183541.GY3351@webber.adilger.int> Attention to all Lustre users. There was a serious problem discovered with only the 1.6.4.1 release which could lead to major data loss on relatively new Lustre filesystems in certain situations. The 1.6.4.2 release is being prepared that will fix the problem, and workarounds are available for existing 1.6.4.1 users, but in the meantime customers should be aware of the problem and take measures to avoid the problem (described at the end of the email). The problem is described in bug 14631, and while there are no known cases that this has impacted a production environment, the consequences can be severe and all users should take note. The bug can cause objects on newly formatted OSTs to be deleted if the following conditions are true: OST has had fewer than 20000 objects created on it ever ------------------------------------------------------- This can be seen on each OST via "cat /proc/fs/lustre/obdfilter/*/last_id" which reports the highest object ID ever created on that OST. If this number is greater than 20000 that OST is not at risk of data loss. The OST must be in recovery at the time the MDT is first mounted ---------------------------------------------------------------- This would happen if the OSS node crashed, or if the OST filesystem is unmounted while the MDT or a client is still connected. Unmounting all clients and MDT before the OST is always the correct process and will avoid this problem, but it is also possible to force unmount the OST with "umount -f /mnt/ost*" (or path as appropriate) to evict all connections and avoid the problem. If the OST is in recovery at mount time then it can be mounted before the MDT and "lct --device {OST device number} abort_recovery" used to abort recovery before the MDT is mounted. Alternately, the OST will only wait a specific time for recovery (4:10 by default, actual value printed in dmesg) and this can be allowed to expire before mounting the MDT to avoid the problem. The MDT is not in recovery when it connects to the OST(s) --------------------------------------------------------- If the MDT is not in recovery at mount time (i.e. it was shut down cleanly), but the OST is in recovery then the MDT will try and get information from the OST on existing objects, but fail. Later in the startup process the MDT would incorrectly signal the OST to delete all unused objects. If the MDT is in recovery at startup, then the MDT recovery period will expire after the OST recovery and the problem will not be triggered. If the OSTs are mounted and are not in recovery when the MDT mounts then the problem will also not be triggered. To avoid triggering the problem: -------------------------------- - unmount the clients and MDT before the OST. When unmounting the OST use "umount -f /mnt/ost*" to force disconnect all clients. - mount the OSTs before the MDT, and wait for the recovery to timeout (or cancel it, as above) before mounting the MDT - create at least 20000 objects on each OST. Specific OSTs can be targetted via "lfs setstripe -i {OST index} /path/to/lustre/file". These objects do not need to remain on the OST, there just have to have been that many objects created on the OST ever, to activate a sanity check when the 1.6.4.1 MDT connects to the OST. - upgrade to lustre 1.6.4.2 when available Cheers, Andreas -- Andreas Dilger Sr. Staff Engineer, Lustre Group Sun Microsystems of Canada, Inc.

This material has existed for some time but was closely guarded intellectual property by the former CFS. In the spirit of making Lustre continually more open, we have been encouraged by Sun execs to make this valuable information available to the Lustre community. Lustre High Level Designs (HLD): http://arch.lustre.org/index.php?title=LustreHLDs Lustre Detailed Level Designs (DLD): http://arch.lustre.org/index.php?title=LustreDLDs Lustre Internals: http://wiki.lustre.org/index.php?title=Lustre_Internals Lustre HLDs and DLDs are available for download from the CVS repository in their original Lyx format. The HLD and DLD wiki pages include CVS download instructions. Additionally, each wiki page has links for the most current design documents available in PDF format. For each PDF, the author and date are listed, along with a synopsis. Over the coming days, we'll continue to make more of the 2008, 2007 and 2006 HLDs and DLDs available as PDFs on the wiki pages. Note that some of this documentation may be out of date, incomplete, or not yet implemented in Lustre. But it still provides useful reference material for understanding Lustre. The Lustre Internals course was taught a few times in the past year by Peter Braam. We've decided that it represents more of a useful knowledge resource than course material. It is our hope that this documentation will contribute to nurturing a stronger and more vibrant development community for Lustre.

This bug can result in the journal device entering read only mode after an umount then remount. A normal mount on boot will not be affected There is a patch applied to the bug and this fix will be in both 1.6.7 (which is in release testing atm) and 1.8.0. Regards PJones
