I've got a broken jfs file system on a Apple Xserve RAID attached
to PC with Fedora Core 3. A replacement drive was installed,
the RAID apparently hiccuped, and the jfs kernel module became
very unhappy. We had to reboot to get the RAID to rebuild, and
now the file system won't mount. fsck.jfs craps out during Phase
1, and exits with exit code eight. Details follow.
Interestingly enough, fsck.jfs -n reports some extra info...
Secondary file/directory allocation structure (2) is not a
correct redundant copy of primary structure. [fsckimap.c:909]
Also of interest: the superblock looks identical to the superblocks
on other identically configured machines.
Is there any hope of fixing it? Or should I call it dead?
