This is a known issue. Clusters crashed on the node which is showing disconnected. The fix will be released in 3.7.2

Hi Team,

Recently I started working glusterfs and created the following home setup:

Total nodes: 4

gluster02.myhomedomain.com
g2-node2.myhomedomain.com
g2-node3.myhomedomain.com
g2-node4.myhomedomain.com

I created a replica volume (Name: replvol) on nodes gluster02 & g2-node2. I was able to mount the volume on my client vm and copy some files.
Now I created 2 bricks (one each on g2-node3 & node4) and ran add-brick on the replica volume. The bricks got added to the volume and the info is listed in replvol.info file.
Even at this stage the peer status shows that the peers are in cluster and connected.

Once I run: 
                             gluster volume rebalance replvol start

              

I see that the status of the peers (only g2-node3 and g2-node4)  are moving to "disconnected" and the status of g2-node2 is still "connected".

If I stop the volume and restart the nodes, they are getting back connected. Once again if I run rebalance, they are moving to disconnected state.

As I am not sure which specific files to share, so I am attaching the logs from gluster02, g2-node3 and g2-node4.

All nodes are running CentOS 7.1.1503 and glusterfs: 3.7.1
No issues with connectivity between the nodes. 

I also have a distributed volume up and running. I was able to add-bricks to the distributed volume and rebalance.

Any help to troubleshoot the issue will be appreciated.

Thanks,
Suneel
