i run a 2 node cluster and want to be save in split-brain scenarios. For this i 
setup external/ipmi to stonith the other node.

Some possible issues jumped to my mind and i would ike to find the best 
practice solution:

- I have a primitive for each node to stonith. Many documents and guides 
recommend to never let them run on the host it should fence. I would setup 
clone resources to avoid dealing with locations that would also influence 
scoring. Does that make sense?

- Monitoring operation on the stonith primitive is dangerous. I read that if 
monitor operations fail for the stonith device, stonith action is triggered. I 
think its not clever to give the cluster the option to fence a node just 
because it has an issue to monitor a fence device. That should not be a reason 
to shutdown a node. What is your opinion on this? Can i just set the primitive 
monitor operation to disabled?

Thank you.
