Note that if resource is stopped _just_ for this period (in seconds)
while monitor is set to a bigger value (30 s), pacemaker may miss the
resource being intermittently stopped.

Just for clarification, do you mean stopped completely within the
cluster and not just on the node the group was running when one of
its resources stopped?

Why do you have target-role=stopped (should preferably be title-cased
"Stopped") here/is that only for the test purposes?  I ask as it may
intefere with any subsequent modifications.


P.S. The presented configuration resembles output of clufter, so any
feedback to be turned into its improvements welcome.
