Hi Anuradha, Thanks for the advice, the version i use is 3.8.
You are correct with my requirement with original 2 nodes ( Distributed - Replicated Mode ) expanded to 3 nodes ( Distributed - Replicated Mode ).May i know the additional work for heal to be triggered based on the glusterfs version 3.8 ? My another question is : IF i only have 2 bricks in each nodes, any possibility add the 4th node ( also only have 2 bricks ) or 5th node etc.. to the cluster ? With the condition cannot add more brick to existing node. Thank you for the guide.
