Um, that's not consistent with the config. What you're running is a
single-instance MySQL LSB primitive; for a Master/Slave replication
managed by Pacemaker you would use the OCF resource agent
(ocf:heartbeat:mysql) and wrap it in a master/slave set.

There is no trace of that in the config either.

IIRC that's a no-can-do in a symmetric cluster; Pacemaker will pretty
much always execute the probe.

Er, no. That cidr_netmask is incorrect.

4 nodes, 3 votes? Did you meddle with this manually?

Bad idea.
