Inspired by “What’s a good piece of hardware to run a jellyfin server?” I wanted to get the communities thoughts on how to set up my home media server.

Current hardware: Apple Mac mini “Core i7” 2.3 (Late 2012) with 8GB RAM (2x4GB) and 1.0TB Mercury Electra 6G SSD that I upgraded

OS: OMV6 (6.9.14-1 (Shaitan))

Docker containers:

Goal:

  • Use this old Mac Mini for as long as possible as a media server. Be able to download with Transmission over VPN and then add them to a Plex media folder via SMB on my Mac Studio. I want to manage the containers in Portainer and I’ve used Stacks/Compose to add most of the containers. Use the discrete GPU for hardware accelerated transcoding, mostly so I can download movies to my iPad quicker, less so other people can use it remotely. The containers should restart if they stop and I want to keep them updated automatically if possible. I’ve not experimented with Servarr yet (Radarr, Sonarr), not opposed, but also happy to drag them over.

Problems:

  • I don’t love OMV, I seem to have a recurring DNS issue with containerd that causes Plex to stop whenever I’m watching a movie. I can run a test and leave something playing all day and not have a problem, then whenever I want to watch something with my wife, the whole system becomes unavailable and I have to watch a ping until it comes back. I’m considering a new OS, it should be accessible via VNC/SSH and have my internal and external drive shared as a SMB share to my Mac. I can’t figure out how to get the GPU to be seen by OMV so everything is on the CPU, an OS where this is easier is preferred.

Questions:

  • Any OS recommendations to use instead of OMV6?
  • Advice on getting the discrete GPU seen in whatever OS I use?
  • I can’t tell if it’s Haugene causing the DNS issue, I’m using public Google/CloudFlare DNS to avoid using my PiHole that runs on a Pi3b. Can I set up Docker to use a different network so it doesn’t bring my whole system’s IP down? It might also be Watchtower updating a container and bring it down, any advice to troubleshoot would be appreciated.

Disclaimer:

  • IT guy, but mostly Mac. I can Google my way through most things, but I am NOT a Linux or Docker expert. So please go easy on me if I have any follow up questions!

Thank you in advance!

    This is incredibly helpful CurbsTickle!

    Sorry this is probably a super dumb DNS questions, should I be setting my OMV DNS to the IVPN DNS or just my Transmission/OVPN Docker stack? I tried using the OpenVPN DNS here and it doesn’t connect when set in the stack, OMV or both. I also have PiHole on a Pi (maybe I can move that to Proxmox and use 1 system?), which is why I was using the Google Public DNS in OMV and the Haugene stack which seemed to work, apart from the weird issue I’m seeing randomly.

    Honestly, I might scrap this configuration and put the time into getting Proxmox setup on this machine, try to get it in a good working order and then look at a tiny/mini/micro for later down the line. I’ve started watching more Anime and honestly the subtitle transcoding worries me a bit!

    Any personal preferences or suggestions on hardware outside of the beelink s12pro which I’m checking out? I’m also hoping to cannibalize the SSD which isn’t that old, the RAM might be useless at this point.

    Also any guides/tutorials you can suggest for getting a working Proxmox setup running similar to yours?

      Only your container with VPN connection and transmission would be using the VPN’s DNS

      With regards to the pihole, yeah I’d run that as a container on proxmox (there are some handy scripts by [tteck](https://tteck.github.io/Proxmox/, though I’m not generally a fan of running shell scripts off the net like this it is easy). But I wouldn’t get rid of the pi, I’d keep it as your secondary. Single point of failure means it will drive you nuts if you have to reboot the server, everything will be down.

      Outside of the beelink, it’s just the tiny/mini/micro options from Lenovo/HP/Dell, and then by generation of CPU. The beelink is a popular choice, but personally I like the power that an i5/i7 will give me, and I’ve got a couple of machines with 32GB and 64GB of ram - throwing 16GB at a VM I can access remotely for Windows apps is super useful, and I can otherwise live in my Linux desktop.

      I’d also say you don’t have to toss the 2012 Mac mini, you can grab some bits you want (SSD), but you can drop in a replacement and make it another proxmox host. Even run your second pihole there.

      In terms of guides, sorry don’t really have any on specifically my setup no. But there are ones out there to learn how to set up an LXC as a docker host, docker networking, guides to the *arrs being set up, etc.

      Such as this one for a VPN container, and docker-compose samples for having other containers use that network: https://www.naturalborncoder.com/linux/2021/02/19/making-a-docker-container-use-a-vpn/

      For a good start on how to set up (after the containers are running) sonarr/Radarr/etc, check out: https://trash-guides.info/

      And you can always ask questions in the various home server communities here (and elsewhere on the fediverse obviously).

      Good luck!

        Hey CurbsTickle

        Thank you so much for the tips, with a mix of googling, bit of GPT4 and straight smashing my head against the desk, I’ve gotten Proxmox installed on the Mac Mini and ordered 16GB of RAM (figured it’s worth the $40). Fought a serious battle trying to get to the startup manager with my mechanical keyboard and Dell monitor, eventually got it to boot from the thumb drive and install. I’ve got an LXC setup with Debian 12 and installed Plex, even managed to get my existing Plex Media folder from my external drive mounted in the container!

        Next steps are the IVPN Wireguard killswitch VPN LXC and Transmission LXC, based on the quick reading I’ve done, it looks like iptables rules is the way to go. I’ll more than likely be writing a big post in selfhosted lemmy soon asking if anyone has achieved this already and has the steps. I might look at the *arrs but that is a later project, I am fine with searching, downloading and renaming/moving the files when I want to watch something. We don’t have regular shows we download right now.

        Final questions before I head into the deep dark world of home server communities.

        • Doing the Plex setup quickly, I gave it 1 core and 1GB of RAM, gonna guess this isn’t enough, if I’m doing Direct Play and transcode for subtitles, how much RAM and how many Cores would you throw at it with my system?
        • Can this be updated or do I need to create a whole new lxc container if I want to add more cores/ram to it?
        • For my HD 4000, is it of any use to me with Plex, or is it already being utilized due to it being integrated?
        • Can I setup a SMB share from the mounted disk in Proxmox? I created a mount point in Proxmox and then edited the containers config file so it mounted in the container.
        • Any final tips on MUST DO setup on the Proxmox side? Happy to nuke a container and recreate it if need be, but I’d like to make sure the Proxmox side of the house is in a good place from day 1!

        Thanks again

          iptables is a solid choice for the regular Linux side (or an LXC), if you use a docker container though, you can just use the docker network to restrict access - you can see a solid example of that here:

          https://tcpip.wtf/en/force-docker-containers-vpn-gluetun.htm

          Regarding your questions:

          • Good enough for direct play, and for SRT subtitles, but any image subtitles (pgs, vobsub) will transcode. If you can use GPU for transcoding, it won’t matter, it’ll come down to how much simultaneous use you’ve got more than anything. You can view how it’s running from the summary page of the VM/LXC, and adjust accordingly whenever. Just give it another core, shutdown, start back up, and you’ll have more cores applied - ready to test again. (One of the reasons I like proxmox).
          • You can update any time, just need to shutdown and start up again to apply hardware changes! The only thing you can’t change easily is privileged/unprivileged LXCs. For now don’t worry about that.
          • A privileged container can access the hardware on the host, but an unprivileged container can’t (without some extra shenanigans). I’d make it privileged for now, if you want to change later after you’ve gotten some experience you’ll be able to do so much more quickly. The HD4000 will do pretty well with h264 video, but won’t help with h265/hevc, so stick with h264 for anything with subtitles.
          • Sure can! You can actually mount it to the LXC from proxmox with a simple command:

          pct set XXX -mpX /host/dir,mp=/container/mount/point

          Where XXX is the container number, and mpX is the mount number. Mount Point 0 is the first (mp0), the next directory you mount is mp1, etc.

          • Check out tteck’s helper scripts for an idea on the things you can do. Personally I recommend making the LXCs yourself, but these scripts are good to use to get familiar with what you can do:

            Thank you for answering my questions, I spent some time over the weekend performing testing. Sadly I suspect all my problems stem from my NIC failing. The loss of IP that I was seeing in OMV is still happening in Proxmox. Now trying to decide next steps, I can either keep throwing money at it and get an external Ethernet solution with compatible drivers or finally put this Mini to rest. I’ll probably make a post on the selfhosting community and see if anyone has any recommendations for hardware. Little peeved I bought the RAM and have this SSD with nowhere to make use of them. Maybe I can find a suitable machine that can use them, but I’m gonna guess they’ve aged out of the CPUs I’d need for better performance. But I am very happy with the Proxmox, LXC and Debian suggestions.

              Definitely unfortunate…

              What I’d recommend maybe looking at then is an off lease Lenovo/HP/Dell tiny/mini/micro - on eBay I’m seeing a Dell 3050 with 6th gen i3 for ~$60, a 7050 with an i5 6th gen and no HD for the same price (better purchase right there), or an i7 6th gen with a 256gb drive and 16gb ram for $120.

              Anything like that, and swap in the SSD if it will take it, then you could put proxmox on one disk and dedicate the second SSD to your media server VM.

              Good luck with whichever route you go!

                Thanks for the suggestions, I also tagged you in a post before I saw this. I’ll start researching the off lease options and I don’t hate the idea of a Dell 7050 with an i7. Would be amazing to make use of the SSD still. And really appreciate the advice with going with Proxmox, the UI is a million times better than trying to use OMV and made troubleshooting so much easier!
