"pengine: error: native_create_actions: Resource <name> (<class>:<provider>:<type>) is active on 2 nodes attempting recovery" seen when a node rejoins a RHEL High Availability cluster

Issue

• My resources restarted unexpectedly after a node rejoined, even though I have location constraints and resource-stickiness set to prefer the node it was already running on, and I saw "is active on 2 nodes" errors
