One possible course of action in this situation is to give each member a vote and configure a quorum disk with 1 vote. Expected votes is 4, and quorum is 3. If the quorum disk fails, remove the quorum disk vote by using the clu_quorum -d adjust 0 command. Or, if a member fails, remove the member vote by using the clu_quorum -m failed-cluster-member 0 command. The resulting cluster (expected votes is 3; quorum is 2) would survive another failure.
