(Late to thread - here's an example of what David is talking about):
Node Votes
----- -----
node1 1
node2 2
node3 3
node4 5
Total: 11
Quorate 2-node partition:
- node1 node4 (6 votes / 11)
- node2 node4 (7 / 11)
- node3 node4 (8 / 11)
Inquore 2-node partition:
- node1 node2 (3 / 11)
- node1 node3 (4 / 11)
- node2 node3 (5 / 11)
Effectively, no matter how a 2:2 partition occurs in this configuration,
one partition will always have quorum (and thus be able to fence). Like
a normal 4-node cluster, one node can always fail while the other 3
nodes remain quorate.
