  • Sync Local DNS and Lists on second pihole - latest way?

    OR I could implement https://github.com/vmstan/gravity-sync as it's last commit was a year ago but users still seem to be using it.
  • Have any idea ?

  • Two piholes and both with unbound?
    2 projects | /r/pihole | 31 May 2023
    As others have said both instances should be totally complete as the idea is if one goes offline you should still have another that functions exactly the same. I also run Gravity Sync in my environment, helps keep down the maintenance. When I whitelist a domain on one it syncs to the other within minutes, that kind of thing.

    the github page has a really good walkthrough and explanation
  • Running PiHole on a second server

    I don't have anything add to your question. But I recommend installing gravity-sync if you're going to run two piholes. It will sync up DNS entries (among other things) automatically to the second pihole when you add a entry one of them. https://github.com/vmstan/gravity-sync
  • Using RPi for Pihole and remote access gateway
    2 projects | /r/selfhosted | 21 Apr 2023
    Run Pihole on both, if DNS goes down its painful. You can sync them with https://github.com/vmstan/gravity-sync
  • Who else doesn’t work in IT? What are you struggling with today.

    Hmm, per their GitHub page, "Starting in Gravity Sync 4, replication of static DHCP assignments is now supported." (Found here: https://github.com/vmstan/gravity-sync/wiki/DHCP-Replication) -- But, as I stated before, I don't use PiHole for DHCP reservations so I can't comment on if it does or doesn't work.
  • What do you run your Pihole on?
    2 projects | /r/pihole | 3 Apr 2023
    They're separate DietPi installs with Gravity Sync to keep the lists synced, but they each maintain their own resolver (unbound) caches upstream, and all clients are configured for primary (Pihole) and secondary (Bihole) addresses, then a firewall rule on the router that forwards any traffic to port 53 (AKA DNS) to Pihole. They both feed metrics to a single host that gives me a custom dashboard. Secondary unit gets less traffic, so I also run NUT (Network UPS Tools) on it to control my APC UPS.
  • Homelab DNS?

    Two pi holes with gravity sync? Then it wouldn't matter which one it hit https://github.com/vmstan/gravity-sync
  • Backup DNS if/when AdGuard container doesn't work
    3 projects | /r/mikrotik | 7 Mar 2023
    I decided to setup a 2 node replicated cluster with Pi-Hole using this excellent collection of scripts - https://github.com/vmstan/gravity-sync You can probably adopt it to use AdGuard since it has even simpler configuration than Pi-Hole. Here are some ideas how to do that here - https://github.com/AdguardTeam/AdGuardHome/issues/573
