</div></div>I usually use the crm shell so I'm not positive but I think these are the parts you need...<br>
<br>
$rsc_$task_$interval@$node=$rc<br>
<br>
$rsc = resource to test, in your case I believe you want to specify the primitive instance of the clone i.e. p_resource:0<br>
$task = monitor or migrate or stop or whatever operation you want to take<br>
$interval = the interval of a monitor task<br>
$node = the node<br>
$rc = the exit code you want to fail with i.e. error, not_running<br>
<br>
So (I think) something like:<br>
--op-fail=$p_of_clone_resource:0_$monitor_$10@$node1=$not_running<br>
<br>
You *should* be able to experiment till you get it just right since its simulate.. :-)<br>
