I've come across this same issue (I was using vol files thinking they 
would tell the client how to mount without relying on one hostname).

For example, I have a test distributed-replicated cluster of 10 servers 
and 2 client set up.  If I have the client set up to "mount -t glusterfs 
server1:/volume /mnt/volume" and I take down server1, everything still 
works.  But if I try and mount server1 again (with the above command) on 
another client it will complete the mount command but then just sit 
there and hang the machine if you try and do df or cd into /mnt/volume.

Basically I want to have a reliable way of mounting from clients just in 
case a machine tries to mount a Gluster volume when one of the servers 
in the cluster is down.
