[Pacemaker] votequorum for 2 node cluster

[Kostiantyn Ponomarenko]

two_node option is my another question. I think it's not for this thread.

So, anyway the only node will remain working in split brain (or one node
shout down) situation is that with the lowest id.
And that is like roulette, in case we lose the lowest nodeid we lose all.
So I can lose only the node which doesn't have the lowest nodeid?
And it's not useful in 2 node cluster.
Am i correct?


Thank you,
Kostya
