Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
ALERT: The filesystem has valuable metadata changes in a log which is being
ignored because the -n option was used.  Expect spurious inconsistencies
which may be resolved by first mounting the filesystem to replay the log.
