There might be other ways, probably cleaner, but you can always:
* put the cluster into maintenance-mode
* shutdown the cluster stack on all nodes (pacemaker + corosync)
* reconfigure the ring(s) on all nodes
* start corosync on all nodes
* test connectivity (corosync-objctl | fgrep members)
* start pacemaker
