Hi Luke,
I had tried a variation of what you have suggested which was:
monitor_()
{
touch /monitor
return $OCF_NOT_RUNNING
}
just to see if start is getting called at all, but to no avail.
I just did exactly what you suggested but I still only see /monitor file.
One interesting thing is that in the <status/> section I only see
monitoring related details without any start or stop related details
for my resource on a node.
If start should have happened it should have been part of the status
information, it's vital status information.
