Gluster repl node replacement.md

In a replication cluster, one of the nodes fails. I replace it with a new machine with the same hostname and address as the failed node. Then, with glusterd stopped on the replacement and running on the survivors

  • Get UUID of failed node from /var/lib/glusterd/peers on one of the survivors
  • Give it to the replacement node by putting it in /var/lib/glusterd/glusterd.info
  • Start glusterd on the replacement
  • On replacement, peer probe one of the survivors
  • Restart glusterd on replacement
