No.  AFS does not distribute the contents of a volume across multiple 
partitions, either on the same server or on different servers.

What you can (and should) do is set up a small /afs/<cell>/home which is 
replicated across both servers, and then create separate volumes for each 
user, mounted inside it.  Each individual user's volume would reside on 
only one server, but it is easy to move them around to balance space usage 
(in fact, there are automated tools available for this), and such moves are 
completely transparent.
