I am wondering if I am understanding carp interfaces correctly. I
have a SPAM gateway that runs on two servers. I want to enable a
failover scenario. I want to test the interface on the backup server.
So the primary server is shut down. I enable carp and it starts up
fine and works for a while but after a while the port stops responding
to ping or anything else.
Did I miss something in the setup or is this a bug of some sort?
Do I need preempt for a failover?
I assume the backup interface (advskew 100) can start without the
primary being up yet?
Here are my settings:
net.inet.ip.same_prefix_carp_only: 0
net.inet.carp.allow: 1
net.inet.carp.preempt: 0
net.inet.carp.log: 1
net.inet.carp.arpbalance: 0
net.inet.carp.suppress_preempt: 0
