Is it specifications?
I tested it using the same configuration in Pacemaker-1.0.
As expected, the behavior of the resource differed in Pacemaker-1.1.
At the time of monitor(on-fail="stop") failure,
- Pacemaker-1.0:
the resource stopped and did not start elsewhere.
- Pacemaker-1.1:
the resource stopped and started again on a different node.
