Summary: XFS_FSR corrupts filesystem during reorganisation
Product: Linux XFS
Version: Current
Platform: PC
OS/Version: Linux
Status: NEW
Severity: critical
Priority: P1
Component: xfsprogs
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: igor@xxxxxxxx
I've set up xfs_fsr to run daily at 3:00 AM, and it frequently causes XFS
filesystem to shut down..
1st occurence:
--------------------------------------------
Filesystem "sda": XFS internal error xfs_trans_cancel at line 1169 of file
fs/xfs/xfs_trans.c. Caller 0xffffffff803b4f06

--------------------------------------------
resolved by remounting FS, log replayed, no errors found by xfs_check then.
2nd occurence:
--------------------------------------------
xfs_iunlink_remove: xfs_itobp() returned an error 117 on sda. Returning error.
xfs_inactive: xfs_ifree() returned an error = 117 on sda

Now the corruption is more severe. FS won't mount, saying:

XFS: log mount/recovery failed: error 117
XFS: log mount failed
--------------------------------------------
Resolved by 'xfs_repair -L /dev/sda' two times (as the first one didn't repaired
one error) and the it checked & mounted OK.
OS: Gentoo Linux x86_64
Kernel: 2.6.23-gentoo-r3 (equivalent to ~2.6.23.12 + some other patches by
gentoo community)
XFS-Progs: 2.9.4
XFS-Dump: 2.2.46
Hardware seems OK, physical backend is RAID5 3.5Tb (one full-size XFS filesystem
without partitioning) on Adaptec 8-port PCI-X controller. Memory was checked
too.
