Running crm_mon without arguments simply says "Waiting until cluster is
available on this node ..."
There's no pacemaker service yet so it can't get us any information. The
"pcs status" says as much too "Error: error running crm_mon, is pacemaker
running?"
My curiosity has been satisfied for now. Although I still feel my
question should have some answer like:
"Yes, if you enable the read_Johns_mind flag. But you will have a very
high risk of split brain."
Thanks again for your attention.
