[info-afs] Bogus volume after rebuild

[Jeffrey Hutzelman]

You probably want to send your message to openafs-info; this list doesn't
get much traffic these days, and doesn't have nearly as many subscribers,
either.

This is what the salvager does when it finds data belonging to a volume
without a volume header.  Since it doesn't know the volume's real name, it
makes one up.
The first thing you should do is look up that ID in the VLDB and see if
it's a real volume you care about.  Sometimes they end up being temporary
clones left over from a move or release, or data belonging to a volume
that no longer lives on that server.

error 9 is EBADF.  I'm going to guess that the problem here is that the
link table for that VG is corrupted or missing.  Unfortunately, the
salvager doesn't know how to deal with this situation.

Well, yes; since you used -noauth, the request is made without
authentication, and the bosserver denies it.  Performing this operation
requires that you be authenticated as an administrator listed in the
UserList, or else run it on a fileserver with -localauth
