REVIEW: http://review.gluster.org/5442 (NFS: server nfs and unlock doesn't happen) posted (#1) for review on master by Santosh Pradhan (spradhan)
The fix is not needed. This is basically a configuration issue. Problem description: glusterd service conflicts with nfslock service. Description of FIX: If the machine is going to run the Gluster NFS server, it's advised to stop the nfslock service (rpc.statd daemon) because Gluster NFS is going to start rpc.statd anyway. It is better to turn the nfslock service OFF through chkconfig or so to make it persistent across reboot.
Am closing it. This is not a issue in code but a config issue.
