High availability / CARP DHCP Cluster - Failover Split Ignored
« on: December 30, 2023, 10:09:27 pm »
I have a 2 node DHCP CARP cluster setup. I only want the primary handing out leases (whichever happens to be primary at the time) so I've set the Failover split to 256. XMLRPC Sync has replicated the Failover split value of 256 to the secondary node (the text help states it will be ignored on the secondary so this should be fine, but the text help also says to leave the value blank on the secondary which XMLRPC Sync does not do.)
However, it seems both the primary and backup are still handing out DHCP leases. I tried fixing this by setting the response delay on the backup, but that value gets wiped out as soon as the config gets synced from the primary so that won't work.
Any idea how I can get only the primary to hand out DHCP leases via the Failover split value?
