We're still not sure what the initial hardware problem was, but
whatever it was we got off pretty easy.  After a long night, I
had everything back up with very little lost.  In fact, I'm not
quite sure that anything was lost.  In a quick look over the
logs, I think almost all of the AFS volumes which were damaged
by the Thursday night problem were RO replicas.

And the end of all that, I have only two volumes which the file
server process could not attach when I bought the file server
back up.  And those two were the two unused user volumes which
started this thread.

I'm inclined to go with 'salvager -oktozap' for those to volumes,
and then restore them from backup.  But I'm going to wait until
Monday morning to do that.

Thanks for all the replies!
