title: unable to peer probe in glusterfs : Transport endpoint is not connected
body: <p>We are implementing a 3-node openstack cloud using glusterfs for storage solution. 3 nodes : controller compute and network are peers in gluster. We need to add another compute node as a peer in gluster but it is showing the following error :</p>
  
  <pre><code>[root@newcompute2 ~]# gluster peer probe 192.168.10.3
  peer probe: failed: Probe returned with Transport endpoint is not connected
  </code></pre>
  
  <p>where 192.168.10.3 is the IP of controller node. Logs are also showing the same error.
  Please suggest what may be the reason for this and the required solution.</p>
