We started investigating this problem and noticed that cache memory is slowly increasing. We tried to dump this cache memory using: /bin/echo "3" > /proc/sys/vm/drop_caches In a result, cache was dumped, but in logs we noticed a lot of errors with XFS: [kern.warning] kernel: xfs_iunlink_remove: xfs_inotobp() returned an error 22 on dm-16. Returning error. [kern.notice] kernel: xfs_inactive:\011xfs_ifree() returned an error = 22 on dm-16 [kern.notice] kernel: xfs_force_shutdown(dm-16,0x1) called from line 1406 of file fs/xfs/xfs_vnodeops.c. Return address = 0x [kern.alert] kernel: Filesystem \"dm-16\": I/O Error Detected. Shutting down filesystem: dm-16 [kern.alert] kernel: Please umount the filesystem, and rectify the problem(s) [kern.warning] kernel: xfs_imap_to_bp: xfs_trans_read_buf()returned an error 5 on dm-16. Returning error. [kern.warning] kernel: xfs_imap_to_bp: xfs_trans_read_buf()returned an error 5 on dm-16. Returning error. [kern.warning] kernel: xfs_imap_to_bp: xfs_trans_read_buf()returned an error 5 on dm-16. Returning error. We are wondering if this is problem connected to hardware or rather this is XFS problem (if yes, was it fixed?).
