It can, of course, but that's still no failover, since you have just  
one RW copy.
If that server goes down, you _can't write_, and besides that, you  
have to mount the RW volume differently, so your user will have  
another path to the RW copy. That's definitely not what people call  
full replication of data.

This is documented that way and AFS people never claimed to have this  
feature (R/W replication of data across fileservers).
