[Gluster-users] howto disable gluster nfs on one computer

[Craig Carl]

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.

Thanks,

Craig
