So the test is a 2 part one, check the process is running and then make a call against the a status api.
There is a timeout period associated with the api call so I check first to see if its running

Don't think so as it runs fine and then occasionally fails

Oh silly me I was using the lib error codes an mistook 
$OCF_ERR_PERM as permanent not permissions !

But does this mean that pacemaker will not try and move the resource (IP) to the other node.
