Hi!
I'm building a Pacemaker cluster on top of Corosync 1.4.2. I started
with 3 nodes, so their corosync.conf files contain:
quorum {
provider: corosync_votequorum
expected_votes: 3
}
Now I'm adding a new node, which has a very similar configuration, but
with expected_votes: 4. My question: what happens in a cluster where
the nodes have different values for expected_votes? The new node joined
the cluster all right, and crm status reports:
4 Nodes configured, 4 expected votes
on all nodes (even on those with expected_votes: 3). This seems just
fine, but I fear I might be hit by unobvious repercussions later. I can
restart corosync on the other nodes after adjusting their config, but
sooner of later I'll be in a similar situation again...

Feri.
