VME Cluster maintenance - how to reboot one node at a time

We have a new (4) node cluster. I put (1) node into maintenance mode and from the VME told that node to stop. That did not go well. It took a long time to reboot with a lot of sigkill calls, failed unmounts and term timeouts. Once the node was back online the cluster looked good (pcs cluster status) but all of the VM's had been stopped. I had to manually restart the VME VM.

What is the proper way to do rolling server (host) maintenance in a VME cluster? Obviously the way I did it was not correct. Thanks.

Related question, how is Ubuntu patching on the hosts done?  What is the recomended way to perform host maintenance?
