You can specify the lock server for an AFR, but it defaults to the first 
specified subvolume I believe.  Each client requests a lock from that 
server.  I can see some situations where there might be lock guarantee 
problems (server invisible to some but not all clients), but it I don't 
know the details of how it works.
