    SubjectCan't recover from broken ext3 journal

    I had a harddrive develop hard IO errors in the section of the drive
    that holds the ext3 journal.

    If it try to fsck the filesystem, fsck eventually terminates after
    trying to replay the journal.

    I tried to use debugfs but that fails in similar way.

    When I use tune2fs to try to turn off the journal, even with
    the -f option, it simply reports 'the needs_recovery flag is
    set, please run e2fsck'.

    I've replaced the drive and restored from backups, however, it seems
    rather poor design that I should lose *all* my data on the drive simply
    because the journal won't replay due to an disk error.

    The man pages for 'tune2fs' even implies you can use it for
    the very purpose of removing a broken journal but it doesn't
    work, as I reported above.

    I could comment out the check in the tune2fs source code, however, is
    there a proper way to do this?
