My guess is that you only can get into that state if you have a vldb
that has a mix of old style entries without UUIDs and new ones. If you
have had a VLDB for a long time, you can accumulate a lot of crap in

I had a different problem, but to solve it I wrote a modification to vos:
$ /usr/src/openafs-1.5.71/src/volser/vos help
/usr/src/openafs-1.5.71/src/volser/vos: Commands are:
setaddrs set the list of IP address for a given UUID in the VLDB
$ /usr/src/openafs-1.5.71/src/volser/vos setaddrs -help
Usage: /usr/src/openafs-1.5.71/src/volser/vos setaddrs -uuid <uuid of server> -host <address of host>+ [-cell <cell name>] [-noauth] [-localauth] [-verbose] [-encrypt] [-noresolve] [-help]
The patch is there (against 1.5.71, ass seen above):
It is in OpenAFS since 1.5.74 (Thanks Jeff). So I'd get a 1.5.74 vos
and change the IP addr of the UUID you do not like to something else
and then changeaddr -remove it. Record the UUIDs before you change
anything, because with setaddr you can set anything you want.

setaddr is not "safe" ;-)
