[Gluster-users] Non-Uniform opErrstr output in all gluster --xml commands

Re: [Gluster-users] NFS file locking with gluster 3.7.3

Looking around I get the impression that file locking (NLM) may simply not be supported in glusterfs's built-in NFS server. I get the impression that Ganesha is aimed at supporting NFS better, and presumably supports locking well, so I should give it a try (If I understand well the performance is
