In the world of pacemaker, we don't rely on quorum to the extent that
other resource managers do - so we have no real need to fake having
it.
In your situation fencing[1] + no-quorum-policy="ignore" should
normally be sufficient.
Or add a third with standby=true set (prevents it from hosting
resources) to act as a tie-breaker.
