An update on this, if the master node is rebooted during a failure, the
secondary node takes cover correctly and remains the master as would be
expected.
This makes me think that the priority is set correctly but the second
node for some reason isn't honoring the advskew set by the master correctly.
To illustrate what I mean-
-------------------
| Node A | Node B |
-------------------
| M M | B B | Normal, Node A is master on all CARP IP's
| M X | B M | Failure, incorrect though. Node B should be master.
| - - | M M | Node A Offline, B takes over as master correctly
| B X | M M | After restart, correct behavior. Node B is master.
-------------------
M - Master
X - Down
B - Backup
I've also ran through the CARP troubleshooting guide here to no avail.
https://doc.pfsense.org/index.php/CARP_Configuration_Troubleshooting
Let me know if you need more information or clarification, I'm not sure
the best way to illustrate / communicate my problem.

Hi List,
I'm having an issue with CARP preempt. I have two pfSense machines
running 2.4.1-RELEASE. CARP fails over all individual IPs correctly,
but doesn't preempt correctly in the case of a single failure.
On both machines, I've checked that net.inet.carp.preempt is enabled.
The master appears to be detecting the demotion, as it sets
net.inet.carp.demotion to 240 during a failure, but ifconfig still
reports advskew as 0.
I'm not 100% sure if that number should update, or if the demotion
number is added to the advskew reported by ifconfig.
Relevent sysctl, ifconfig, and log output taken from the master firewall
during a failure is attached.
Any help is greatly appreciated!
