With fencing disabled what we are seeing is exactly what we would expect: The state of the resource is unknown - pacemaker tries to stop it - doesn't work as the node is offline - no fencing configured - so everything it can do is wait till there is info if the resource is up or not. I guess the strange output below is because of fencing disabled - quite an unusual - also not recommended - configuration and so this might not have shown up too often in that way.
