William - Adding an option to disable the Gluster NFS server is in the works (http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=2094). Previous versions of Gluster just re-exported the native client to a uNFS or kNFS service. I think the closer integration may have resolved a lot of these issues but I'll ask the engineer primarily responsible for gNFS to take a look at this thread and respond directly.
