Resolution

Verify if there is a backup of the original filesystem, and if yes, prepare the backup in case clearing the dirty region logging does not resolve the problem.

Attempt to mount the filesystem to see if it is mountable:

# mount <devicepath> /mnt

...where <devicepath> could be /dev/mapper/vg01-lv01 for example.

If it is mountable but still show errors, unmount to allow logging to be cleared:

# umount <devicepath>
# xfs_repair <devicepath>

If the filesystem is still unmountable, use the -L option (force log zeroing) to clear the log:

# xfs_repair -L <devicepath>

Cause

The affected XFS filesystem has corruption which could not be recovered by the kernel:

Jan 22 00:20:52 lab-host kernel: [ 9253.615083] XFS (dm-8): Starting recovery (logdev: internal)
Jan 22 00:20:52 lab-host kernel: [ 9253.619277] XFS: Internal error XFS_WANT_CORRUPTED_GOTO at line 1521 of file /usr/src/packages/BUILD/kernel-default-3.0.101/linux-3.0/fs/xfs/xfs_alloc.c.  Caller 0xffffffffa06dd4a9

As a result mounting was not possible:

The end result was that kernel failed to recover the filesystem:

Jan 22 00:20:52 lab-host kernel: [ 9253.622505] XFS (dm-8): Failed to recover EFIs
