That answer may need a little editing since it seems to be saying two
different things.

	Note that if you configure a quorum disk/partition, you want
	two_node="1" or expected_votes="2" since the quorum disk solves
	the voting imbalance. You want two_node="0" and expected_votes="3"
	(or nodes + 1 if it's not a two-node cluster).
