[OpenAFS] newbie admin question

[jdisher@parad.net]

This is probably a question answered in the documentation, but I've been 
Googling and looking through the docs for a few hours now with no love. 
Hopefully someone has the quick seven-command answer for me.

I have two fileservers, identically configured running Linux.  Both are 16 
disk machines with 3Ware 3w9500-8 hardware raid cards, configured as 1.0TB 
RAID10 arrays.  Their filesystems are laid out as such:

sfs0 root # df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2             3.8G  1.8G  2.1G  47% /
none                  2.0G     0  2.0G   0% /dev/shm
/dev/sda3             913G   32K  913G   1% /vicepa
/dev/sdb3             913G   32K  913G   1% /vicepb

What I would like is for all 4 of the data partitions (sfs0:/vicepa, 
sfs0:/vicepb, sfs1:/vicepa, sfs1:/vicepb) to be part of one distributed 
afs volume (so I can mount it as, say, /data on my client servers).  I've 
not found what is needed to add additional partitions to a volume.

Thanks for the help.
