Title:
fstrim corrupts ocfs2 filesystems when clustered
Status in util-linux package in Ubuntu:
Confirmed
Bug description:
Recently upgraded from trusty to xenial and found that our ocfs2
filesystems, which are mounted across a number of nodes
simultaneously, would become corrupt on the weekend:
[Sun Apr 9 06:46:35 2017] OCFS2: ERROR (device dm-2):
ocfs2_validate_gd_self: Group descriptor #516096 has bad signature
[Sun Apr 9 06:46:35 2017] On-disk corruption discovered. Please run
fsck.ocfs2 once the filesystem is unmounted.
[Sun Apr 9 06:46:35 2017] OCFS2: File system is now read-only.
[Sun Apr 9 06:46:35 2017] (fstrim,1080,8):ocfs2_trim_fs:7399 ERROR: status =
-30
[Sun Apr 9 06:46:35 2017] OCFS2: ERROR (device dm-3):
ocfs2_validate_gd_self: Group descriptor #516096 has bad signature
[Sun Apr 9 06:46:36 2017] On-disk corruption discovered. Please run
fsck.ocfs2 once the filesystem is unmounted.
[Sun Apr 9 06:46:36 2017] OCFS2: File system is now read-only.
[Sun Apr 9 06:46:36 2017] (fstrim,1080,10):ocfs2_trim_fs:7399 ERROR: status
= -30
We found the cron.weekly job which is pretty close to the timing:
47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts
--report /etc/cron.weekly )
# cat /etc/cron.weekly/fstrim
#!/bin/sh
# trim all mounted file systems which support it
/sbin/fstrim --all || true
We have disabled this job across our servers running clustered ocfs2
filesystems. I think either the utility or the cronjob should ignore ocfs2
(gfs too?) filesystems.
