Hi David

   XFS works fine as a backing store for GlusterFS.  We've deployed this 
now to many customer sites, and have not run into issues with it.

   There are many reasons to choose XFS in general, and there are no 
issues with using it with GlusterFS.  Especially on large file transfers.

   Small files are the bane of every cluster file system.  We recommend 
using NFS client with GlusterFS for smaller files, simply due to the 
additional caching you can get out of the NFS system.
