I'm not sure net.inet.carp.arpbalance is compatible with preempt. I'm
not using net.inet.carp.arpbalance myself.

Do the output of ifconfig (MASTER vs BACKUP) change on both nodes
when you unplug one cable ?
In my case, the BACKUP becomes master, but I don't remember if
MASTER switch to BACKUP, or if it remains MASTER. It's OK for
MASTER to stay MASTER, because is then has a lower priority than
the other host.
