depends what went wrong, but in general that error means that metadata
corruption was encountered which was sufficient for xfs to abort
whatever it was doing.  It's not done lightly; it's likely bailing out
because it had no other choice.

You can't "force mount" something which is sufficiently corrupted that
xfs can't understand it anymore...  IOW you can't traverse and read
corrupted/scrambled metadata, no mount option can help you.  :)

If the shutdown were encountered during use, you could maybe avoid the
bad metadata.  If it's during mount that's probably a more fundamental
problem.

kernel messages when you get the "structure needs cleaning" error would
be a clue as to what it actually hit.
