Thank l you. Totally forgot about try to mount read only.
I upgraded to jfsutils 1.1.15 and I'm rerunning fsck now. Hopefully this will
fare better. Otherwise I'll try to move everything off beofre doing anything
risky.
Appreciate the help and fast response.

Have you tried mounting the volume read-only (mount -oro)? jfs will try
to mount a dirty volume read-only, but will not allow it to be mounted
read-write until fsck succeeds against it. If a read-only mount works,
it may be best to back up what you can before trying to fix it again.

That doesn't seem right. You have an old version of jfsutils, not that
it has been updated in a while, but version 1.15 might be worth trying.
You can find the latest at http://jfs.sourceforge.net/

If jfsutils 1.15 fails in the same way, I can try to figure out what's
wrong. I'm not sure I'd find a way to get it to fix the volume or not.
Good luck,
