Just to be clear, when you export a gluster volume via NFS, the clients
are using kernel NFS. The gluster NFS server is the only thing in user
The redundancy you do lose is the automatic fail-over to the other
servers if the NFS server the client mounted from fails.
If you're using replication, you do not lose that when you chose to use NFS.
