That's what pacemaker group does. I am not sure what you mean with
"disable all resources". If resource fail count on a node exceeds
threshold, this node is banned from running resource. If resource failed
on every node, no node can run it until you clear fail count.

"Disable resource" in pacemaker would mean setting its target-role to
stopped. That does not happen automatically (at least I am not aware of it).
