[Gluster-users] Peers not connecting after changing IP address
Hi, I've had a 4 node Dis/Rep cluster up and running for a while, but recently moved two of the nodes (the replicas of the other 2) to a nearby datacentre. The IP addresses of the moved two therefore changed, but I updated the /etc/hosts file on all four hosts to reflect the change (and the peers were all probed by name, not IP). However at each site the other two peers show as disconnected, even though the servers can all successfully talk to each other. Is there some way I can kick this back into life?

Hello, Check the files in the peer directory: /var/lib/glusterd/peers They contain the IP addresses of the peers. I haven't done it but I assume that if you update those files on all servers you should be back online.
