There are many stonith devices which do allow only extactly one connection at a time. The monitor action is often implemented to connect to the stonith device to see if it's alive. Now if you use clones, and the stonith RA is run on more then one node it could happen that the monitor action is triggered at the same time resulting in one monitor action to fail because two instances try to connect to the same stonith device. Am I wrong with that conclusion?
