This, by itself, is not necessarily surprising. The property
"cluster-reheck-interval" defines how often the PE gets re-run, and
defaults to 15 minutes.
This is not dynamically adjusted based on failure-timeouts, and if this
feature becomes more widely used, there probably should be a "better"
way to handle/trigger these while still avoiding swamping the cluster
with empty transitions etc.
In short: right now, if you want a failure-timeout of 30s to be
meaningful, you need to set cluster-recheck-interval to something
shorter.

I'm not sure I perfectly get what you're saying here with the last
sentence. Did the cluster try to restart it, and it failed again, yet
the failure was ignored this time around?
The cluster didn't stop or restart my cloned resource, but it is still
monitoring it.
Which is expected as I configured the on-fail to block.
I see that the monitor section of my ocf is executed every 15s (=monitor
interval),
and that it is still failing (returning with $OCF_ERR_GENERIC)
I find it disturbing that a resource with a failing monitor has a 0
failcount, shows ok in crm_mon and allows to run the depending
resources.
Yes, if I got that right, that would be a problem - please create a
hb_/crm_report and open a bug.
Ok, will create a crm_report containing my tests.

Lars
