I have two servers mpt and lyn. The two servers are file server and db 
server.
The two servers hosts a RO copy of my volume. Only mpt have a RW copy.

On a client near lyn, fs where give me only mpt, and fs gets also.
How to add the other server lyn ?

My file /var/db/openafs/etc/cellServDB knows the two servers .

I'm user MacOSX as client and server. with OpenAFS 1.4
