Hi Pranith - correct me if I'm wrong, but if node1 suffered catastrophic failure and had to be completely rebuilt from scratch, then additional procedures would have to be completed - right?

hi Hareem,
     When the NODE1 comes back up it will automatically be part of cluster and the self-heal of the files will happen whenever they are accessed. If you want to sync the files manually, follow the instructions in http://europe.gluster.org/community/documentation/index.php/Gluster_3.1:_Triggering_Self-Heal_on_Replicate

Can someone please kindly help in the following:

How best to deal with node failures and cluster repairs.


I have a problem. I setup 4 node distribute replicated cluster.

Node1-4

Node1: 192.168.1.100
Node2: 192.168.1.101
Node3: 192.168.1.102
Node4: 192.168.1.103

On Node1 is initiated the peer probe command and formed the storage pool
(Node1 being hypothetical master).

I mounted the glusterfs native client on a machine. Using Node1 is used to
mount the glusterfs onto the client machine.


Now say NODE1 fails and goes offline. How do i add it back to the cluster
and get the cluster back to its 4 node strength.

Do i need to do rebalance or something else.

Your help is greatly appreciated.


Best Regards
Hareem. Haque
