Any which makes pacemaker to think resource stop op failed.
OCF_ERR_* particularly.

If pacemaker has got an error on start, it will run stop with the same 
set of parameters anyways. And will get error again if that one was from 
validation and RA does not differentiate validation for start and stop. 
And then circular fencing over the whole cluster is triggered for no reason.

Of course, for safety, RA could save its state if start was successful 
and skip validation on stop only if that state is not found. Otherwise 
removed binary or config file would result in resource running on 
several nodes.

Well, this all seems to be very complicated to make some general 
algorithm ;)
