Is there an XFS equivalent of the fsck.ext4 message "recovering journal"? (See Does "recovering journal" prove an unclean shutdown/unmount? ).

fsck.xfs is a no-op. So does the kernel log a message, when you mount an XFS filesystem that was not unmounted cleanly?

There does not appear to be a direct equivalent.

file -s /dev/sdb4 is able to show when an ext4 filesystem "needs journal recovery", but it does not detect any difference when I test an uncleanly unmounted XFS filesystem.

xfs_repair does not show any difference either. In fact, the list of common messages in man xfs_repair do not include anything about journal replay. Instead:

The xfs_repair utility cannot repair an XFS file system with a dirty log. To clear the log, mount and unmount the XFS file system. If the log is corrupt and cannot be replayed, use the -L option ("force log zeroing") to clear the log, that is, xfs_repair -L /dev/device. Be aware that this may result in further corruption or data loss.


While ext4 maintains special flags to indicate an unclean unmount, it sounds like XFS only maintains the journal. If the journal is empty then it is "clean"; there is nothing to repair/recover/replay.

(If your OS wishes to detect unclean shutdowns, then it must do so itself, like Windows does :-).
