When using a fuse mount, or libgfapi, with a replica volume, fault 
tolerance is built in. Once mounted, the client connects to every brick 
in the volume. The only possible issue may be the ping-timeout default 
of 42 seconds. This is long to give your tcp connection time to recover 
in the event of a temporary network fault. If your server completely 
dies, however, the client will have to wait for this timeout. I 
recommend leaving the timeout long and instead using servers that don't 
die frequently.

The tip the other guys mentioned have to do with mounting the volume if 
the first server in the volume is unavailable at the time of mount. 
Besides backupvolfile-server you can use a round-robin dns entry to 
resolve mounting if a server is down.
