I would set cluster option "stop-all-resources" so all remaining resources are
stopped gracefully by the cluster.

Then you can stop both nodes using eg. "crm cluster stop".

On restart, after both nodes are up and joined to the cluster, you can set
"stop-all-resources=false", then start your VirtualDomains.
