  • How do the DNS servers resolve local hostnames then? The pihole DHCP integration adds local hostnames to DNS when they are assigned an address. If there’s two DHCP servers handing out leases, presumable only one would be accepted, how then would the DNS servers sync those names?

    I think I had my secondary pihole resolve local names from the primary, and leases were copied over on a cronjob in case the secondary DHCP server had to be enabled.



  • 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.




  • I would encourage you not to split things up too finely. A single repo for your environment would allow you to see all related changes with git. E.g. if you set up a new VM it might need a playbook to set something up, a script to automate a task, and a DNS entry. With a well put together commit message explaining why you’re making those changes there’s not much need for external documentation.

    Maybe if you want some more info organised in a wiki, point to the initial commit where you introduced some set up. That way you can see how something was structured. Or if you have a issue tracker you can comment with research on something and then close the issue when you commit a resolution.

    Try not to have info spread out too much or maintaining all the pieces will become a chore. Make it simple and easy to keep up.
