I spotted this in the release notes, but am unsure how to now actual do this.
I have two machines running carp, as a failover pair, and I normally upgrade
BACKUP, reboot, switch to MASTER, and do the other and flip back.
But I dont quite see how to do this from 13 to 14 - my worry is that when the
upgraded machine comes back up, it will just take on MASTER and I will have two
MASTERs.
I see that it's possible to make the talk the old protocol, but then how do I
move to the new protocol ?
Specify the old protocol in rc.conf on both machines and do the upgrade one at
a time. Once both are upgraded, stop pfsync on the standby machine, change the
version on the active machine, restart pfsync on the standby machine also with
the new version.
Ah, thankyou - I had forgotten pfsync was a service I can stop and
start! Thats the critical bit of info I was missing...
