perform a full consistancy check and fixes (and disgard the journal),
however if myth was recording or updating the DB in either case you could
have problems, journaling just ensures the FS is consistant after a crash,
not the data on it.

Just combine it with regular DB backups and you should be fine. :)
My objective is to have the box do an automatic file system check on
