Set a tiebreaker_ip if you don't want it to survive network splits.
This IP needs to be on the same network as the IPs which map to the
hosts "DB-Primary" and "DB-Secondary", but must not reside on the hosts
themselves (use a switch IP, another host, or gateway)

Also, set monitor_link to 1 in the service_ipaddress ...
