The JFS drive is made up of a combination of two, smaller, hardware
RAIDs. The underlying hardware is reporting no drive failuires in
either RAID, so I have no reason to believe that the problem is due to a
faulty drive. The data corruption followed an unexpected power outage,
so I'm thinking that's the cause.
I just don't want to have to reformat the filesystem and lose all of my
data if it's possible to repair it. (Hence my headaches with jfs_fsck.)
