Description

If there is a CARP IP in INIT on both the primary and backup systems, for instance if a NIC is unplugged on both that has a CARP IP defined, it leads to both wanting to be master and causing various issues because of a preemption problem. That's basically never encountered in production since both systems should never lose link on a NIC in this type of scenario, but needs to be fixed.

To replicate:
Setup a HA pair with CARP IPs on LAN and WAN.
Unplug the LAN NIC on both systems.
CARP should get confused at that point.
