I think stopping cluster resources that way is a bad idea, because the cluster
when started again thinks the apps are up.
There has been a "stop cluster" thread recently. AFAIR there was not perfect
solution. Maybe try to find that thread.

I think there is a "stop all resources" somewhere that might avoid that.

Not a perfect one, I'm afraid.
