Anyone run into a CARP failure after upgrading a primary/secondary to 25.7.8? My nodes had split brain, with half the networks being master on one node, and the other half slave. I troubleshot for a good while and couldn't figure it out. I am running non-HA right now as I had to shut my primary and ride the secondary. Going to roll back the VMs to before the change to test the upgrade again.
On the occasion when that I recall it occurred to me, I put one in persistent maintenance mode to get the networks on one instance. When I disabled maintenance, everything stayed or went back to the primary. It's worked as expected since. I haven't tried it on 25.7.9.
Prepping to upgrade to 26 finally and ran into an issue. One of my nodes (the backup node, in VIP backup mode) will not keep the WAN interfaces down.. I have 2 interfaces, one to Verizon and one to Spectrum. Switching the CARP master to the master node brings them down.. but after a moment, they come back up. I can't get them to stay down. Currently pinned up on my primary node with the interfaces all disabled to the backup. Anyone seen this before?
I haven't found that to be a problem - I'm on spectrum as well. I usually receive the same IP with the same default router.
I will mention that on System: Gateways: Configuration: WAN gateway: Edit, I've checked the
Upstream Gatewayoption (help statesThis will select the above gateway as a default gateway candidate.) and it's worked well for me.
