Thanks, I'll look at this.

Is there a way to get back to normal state without rebooting all
machines and interrupting services?

I thought about a lightweight version of something like:

1. stop pacemaker on all nodes without doing anything with resources,
   they all continue to work
2. stop corosync on all nodes

3. start corosync on all nodes

4. start pacemaker on all nodes, as services are running nothing needs
   to be done

I looked in the documentation but fail to find some kind of cluster
management best practices.
