Hi all:
I have a failover pair of OPNsense routers running in my small ISP. I use CARP+pfsync for all my user-facing networks. My backup node is a bit weaker than my primary (working on hardware upgrades), and my demand has grown quickly (a good problem to have!) such that my backup node can't quite keep up. So if my primary is functional, I do want it handling all the traffic.
Recently, my backup node has on its own changed its CARP priority to -240, which of course makes it master. The primary router was at a priority of 0 at all times.
entering carp maintenance mode, then exiting on the secondary node did cause it to change to a priority of 0, which caused it to become the backup as expected.
What causes a CARP node to change its priority to -240 without human input? How can I get logs/troubleshooting details on that?
Thanks!
