I believe this is true for NFS mounts but not necessarily so for the 
Gluster FUSE mounts. The mount.glusterfs man page shows two methods for 

mount -t glusterfs [-o <options>] <volumeserver>:<volumeid> <mount‐point>
mount -t glusterfs [-o <options>] <path/to/volumefile> <mountpoint>

The second approach relies on local access to the volume file. We plan 
to distribute our volume files to each client and then have them mount 
Gluster volumes based on these volume files.

For occasional access to data on a Gluster volume an NFS mount will 
suffice. But most of our Gluster usage will require constant and 
high-availability access to data on the Gluster volumes. So, we'll 
definitely be going the Gluster FUSE route with distributed volume files.
