1. Manually add the new nodes' IP Address to the /etc/corosync/corosync.conf configuration.on one of the existing nodes in the cluster. This will be a new "memberaddr:"
2. The new configuration should be distributed to all nodes in the cluster. csync2 -xv | scp | rsync
At this point, the new corosync configuration needs to be reloaded which means "openais" service will need to be stopped / started again.
You can do this like a rolling update, bouncing one node in the cluster at a time allowing resources to migrate to other nodes in the cluster.
3. With the new corosync.conf configuration in the cluster, you can now use the "sleha-join" script on the new node.
The only method is to 'stop' and 'start' the openais service with updated corosync.conf configuration which will update it's member / node list in memory.
This has been fixed in SLES12sp2. The command: "corosync-cfgtool -R" reloads the corosync configuration. The sleha-join scripts will do this automatically for you starting with SLES12sp2.
