One or more resources restart throughout the cluster when a node joins in a cluster with pacemaker
Issue
- When a node leaves the cluster, all services are correctly live-migrated / relocated to other cluster nodes and everything seems to work fine. But when the node re-joins the cluster, all services on all nodes get restarted
- When we
pcs cluster starton a node, all of the other nodes restart their copy of a clone resource. Why did node42 restart the fs resource?

- I see all of our resources restart throughout the cluster whenever a node starts up
