[OpenAFS] Duplicate VLDB entries

[Kim Kimball]

What does "vos exam <volumename>" show for any volume with a duplicate?

You might also try running "volinfo" to see what's on disk.  As root on 
fileserver, local command, my "volinfo" binary is in /usr/afs/bin but I 
don't know if that's a default location.

[root@satchmo ~]# which volinfo
/usr/afs/bin/volinfo
[root@satchmo ~]#


[root@satchmo ~]# volinfo /vicepa

volinfo gives a record like the above for each volume it finds on the 
partition -- can't imagine that there really are two volumes with the 
same ID or two volumes with the same name on a single partition, but it 
can't hurt to look.
