My current setup has my DHCP + DNS on my Unifi USG. However, as I have all my apps hosted on a different server (unifi, plex, home assistant, NAS, etc.) I’ve ran into issues trying to get things set up.

Basically, Unifi needs to know where the unifi server is, but it’s assigning the IP address to it.

Should I put DHCP+DNS onto it’s own system? Should I put it on my current server? And any non-Pi recommendations for systems? (I’ve had the PI filesystem clobber itself too many times)

Edit: I’m starting to think that the real problem is having UNIFI on the same system as the server, as it prevents me reconfiguring any of the server routing information without also disconnecting unifi…

Edit 2: I’m going to try switching the server from a static DHCP lease to a static IP. If that’s doesn’t work, then I think I’ll move the unifi server onto it’s own system. Thanks!

    Sidnenote about the PI filesystem self-clobbering: Are you running off of an SD card? Running off an external SSD is way more reliable in my experience. Even a decent USB stick tends to be better than micro-SD in the long run, but even the cheapest external SSD blows both of them out of the water. Since I switched my PIs over to that, they’ve never had any disk-related issues.

      I’ve completely bricked two SD cards using a Pi. The USB option sounds interesting, I’ll have to try it.

      You can use log2ram to mitigate that.

      Alternatively, you can even boot a root filesystem residing on an NFS share, but in the case of a rpi hosting the network’s DNS and DHCP services, you could end up with a chicken and egg problem.

      Yeah, whoever thought that sd cards were a good idea for anything even resembling operating systems is a dum dum

        what do you mean? they’re fine unless you want to read or write to them… wait a minute

          They’re fine if the OS is read-only. Unraid loads from a USB drive, but the entire OS is copied into RAM on boot and there’s barely any reads or writes after that.
