[Gluster-users] Creating cluster replica on 2 nodes 2 bricks each.

[Jose Sanchez]

Hi Nithya

This is what i have so far, I have peer both cluster nodes together as replica, from node 1A and 1B , now when i tried to add it , i get the error that it is already part of a volume. when i run the cluster volume info , i see that has switch to distributed-replica. 

Thanks

Jose
