Very interesting. I'm already running DRBD 9, so that base has already
been covered, but here's some extra information: My test system
actually consists of a single 4-node DRBD cluster that spans two data
centers, with each data center having a 2-node Pacemaker cluster to
fail resources over between the two DRBD nodes in that data center.
But, for the purpose of quorum arbitration I guess these extra DRBD
nodes don't matter, perhaps because four is not an odd number?
