thanks to grep, logs can never be too long :-)

this seems to be an lrm bug.

the crm can handle it when an RA isnt installed on all nodes, but
apparently the lrm never bothers to tell us this is the case and just
returns "unknown error"

which means:
* monitor actions for that resource on that node will fail - making it
look active but failed
* stop actions for that resource on that node will fail - making it unmanaged
