I have two pihole servers running, and each of them have extra host entries. My “main” server is running in a container on my workhorse machine. My “backup” server is running on a RPI like machine.
Occasionally the main server goes down when I’m fiddling. My router points to main as the primary and the backup as the secondary dns.
When both are running, I can only see the extra hosts on the main pihole. If main goes down, I can see the hosts on the backup. What can I do (other than copying the host entries) so that I can always see the extra hosts on both servers?
