  We are running HB 2.1.4 and we replaced a node but didn't change the UUID before bring it back into the cluster. So how we have two nodes with the same name and one is offline and the other is online.

  Should we try to delete the old node or run crm_uuid -w to change the duplicate node back to the old UUID?
