Where do you do DHCP? I had a primary pihole with DHCP enabled and a secondary with a cron job that enabled DHCP if the primary was down or disabled it if the primary was working. The cron job did sync DHCP leases from one to the other but it was a bit janky. I tried to update the secondary to pihole v6 and hosed it so I have no backup for now. I'd like to re-image the secondary and get a better setup - when I have time.
Edit to say I really wanted to try keepalived - that's really cool to fail over without clients noticing.
On the router.
My router is locked down so i assign the vrrp address to wach client (pain in the ass) but it works.
Pivpn takes care or wireguard too.
Debian & ubuntu sudo apt install keepalived
sudo apt install libipset13
