So, basically, you want a 3rd node for quorum only? I find that a
kludge, since the third node needs to be maintained and configured and
managed etc and isn't really allowed to do anything.

Have you investigated other approaches as a tie-breaker? external/sbd
(or, in the RHEL work, fence_sanlock)? boothd?
