To be more specific, if there remains the resource which failed to
stop operation and went to the unmanaged status with its
on-fail="block" configuration,
it would be better to prevent Pacemaker from its shutdown.
Is it difficult to discriminate between "unmanaged(stop failure)" and
"unmanaged(operational)"?
well, stonith-enabled="false" should not be configured...

Thanks,
