This questions pops up over and over again. Pacemaker has to make sure that
your resources aren't up anywhere in the cluster before start them up on
designated nodes. That means that it has to be able to run status/monitor
operations for all configured resources on all configured nodes. You can't
just add a 3rd quorum node into cluster you have to make sure that all RAs
that you use can run on that 3rd node properly.
