I'd follow Jason's suggestion
I've had to do this twice in the 8/9 years we been running AFS. In
our case we would (quickly) rebuild a physical sever, get the raid
attached, mount them as /vicep(x) partitions then perform the VLDB
sync ritual - there may be some old addresses and references in the
VLDB that need tiding up later.
Don't move the databases - that will move the sysid file which could
cause more pain.
You can run with two out of three database servers for a little while
- though i've found that there is the occasional delay in some
operations in this mode as the distributed leadership election between
the remaining two servers seems to kick in more oftern

How about moving the /usr/afs directories from a known good server
to the RW server and doing the same?

there are 2 other RO servers still OK but 2 out of 20 volumes are

what's the best way to proceed after I rekey
PS I also have vos dump files but the 2 aforementiined volumes are
not up to

I suggest connecting the raid drives to another server, possibly one
of your R/O servers. Mount the /vicepX partitions, restart the
fileserver, then run "vos syncserv" and "vos syncvldb" to have the
recovered volumes be remapped to the different server.
