[Proxmox] Jellyfin w/ NAS mount + iGPU passthrough (sh.itjust.works)

Fresh Proxmox install, having a dreadful time. Trying not to be dramatic, but this is much worse than I imagined. I'm trying to migrate services from my NAS (currently docker) to this machine.

How should Jellyfin be set up, lxc or vm? I don't have a preference, but I do plan on using several docker containers (assuming I can get this working within 28 days) in case that makes a difference. I tried WunderTech's setup guide which used an lxc for docker containers and a separate lxc of jellyfin. However that guide isn't working for me: curl doesn't work on my machine, most install scripts don't work, nano edits crash, and mounts are inconsistent.

My Synology NAS is mounted to the host, but making mount points to the lxc doesn't actually connect data. For example, if my NAS's media is in /data/media/movies or /data/media/shows and the host's SMB mount is /data/, choosing the lxc mount point /data/media should work, right?

Is there a way to enable iGPU to pass to an lxc or VM without editing a .conf in nano? When I tried to make suggested edits, the lxc freezes for over 30 minutes and seemingly nothing happens as the edits don't persist.

Any suggestions for resource allocation? I've been looking for guides or a formula to follow for what to provide an lxc or VM to no avail.

If you suggest command lines, please keep them simple as I have to manually type them in.

Here's the hardware: Intel i5-13500 64GB Crucial DR5-4800 ASRock B760M Pro RS 1TB WD SN850X NVMe

If your system is that fucked, I would wipe it and start over. And don't run any scripts or extra setup guides, they're not necessary.

Personally I run all my containers in a Debian VM because I haven't bothered migrating them to anything proxmox native. But gpu accel should work fine if you follow the directions from jellyfin: https://jellyfin.org/docs/general/post-install/transcoding/hardware-acceleration/

Just make sure you follow the part about doing it in docker.

It may be better now but I’ve always had problems with Docker in LXC containers; I think this has to do with my storage backend (Ceph) and the fact that LXC is a pain to use with network mounts (NFS or SMB); I’ve had to use bind mounts and run privileged LXCs for anything I needed external storage for.

Proxmox is about managing VMs and LXCs. I’d just create a VM and do all your docker in there. Perhaps make a second VM so you can shuffle containers around while doing upgrades.

If you plan to have your whole setup be exclusively Docker and you have no need for VMs or LXCs, then Proxmox might be a bunch of overhead you don’t need.

I use the LXCs for simple stuff that does a bare-metal type install within them, and I use the VMs for critical services like OPNSense firewall/routers. I also have a Proxmox cluster across three machines so I can live-migrate VMs during upgrades and prevent almost any downtime. For that use case it’s rock solid. It’s a great product and it offers a lot.

If you just need a single machine and only Docker, it’s probably overkill.

[–] LazerDickMcCheese@sh.itjust.works 3 points 1 month ago (1 children)

Well, the plan was to use a couple VMs for niche things that I'd love to have and many services. But if I can't get Proxmox working as advertised, I'll throw most of that out of the window

[–] 4am@lemmy.zip 2 points 4 weeks ago (1 children)

The easiest solution if you want to have managed VMs IMHO is to just make a large VM for all your docker stuff on Proxmox and then you get the best of both worlds.

Abstracting docker into its own VM isn’t going to add THAT much overhead, and the convenience of Proxmox for management of the other VMs will make that situation much easier.

LXC for docker can be made to work, but it’s fiddly and it probably won’t gain you much in the long run.

Now, all these other issues you seem to be having with the Proxmox host itself; are you sure you have networking set up correctly, etc? curl should be working no problem; I’m not sure what’s going on there.

This is the way I'd imagine. I used this for Plex and this should make iGPU a lot easier.

[–] Tinkerer@lemmy.ca 3 points 4 weeks ago* (last edited 4 weeks ago) (1 children)

I run jellyfin on an LXC, so first get jellyfin installed personally I would separate jellyfin and your other docker containers, I have a separate VM for my podman containers. I need jellyfin up 100% of the time so that's why its separate.

Work on the first problem, getting jellydin installed I wouldn't use docker, just follow the steps for installing it on Ubuntu directly.

Second, to get the unprivileged lxc to work with your nas share follow this forum post: https://forum.proxmox.com/threads/tutorial-unprivileged-lxcs-mount-cifs-shares.101795/

Thirdly, read through the jellyfin docs for hardware acceleration. Its always best practice to not just run scripts blindly on your machine.

Lastly take a break if you can't figure it out, when I'm stuck I always need to take a day and just think stuff over and I usually figure out why its not working by just doing that.

If you need any help let me know!

So I got Jellyfin running last night as an unprivileged LXC using a community script. It's accessible via web browser, and I could connect my NAS. Now I'm having NAS-server connection issues and "fatal player" issues on certain items. I appreciate the support, I'm going to need a lot of it haha

[–] Tinkerer@lemmy.ca 2 points 4 weeks ago (7 children)

This is most likely because of encoding. Did you change any settings in jellyfin for hardware acceleration? Have you passed theough your GPU? You will need to find out what codecs your GPU supports and enable those in the jellyfin hardware encoding spot.

How should Jellyfin be set up, lxc or vm

Either way. I prefer lxc, personally, but to each their own. lxc I think is drastically easier, in part because you don't need to pass through the whole GPU....

Is there a way to enable iGPU to pass to an lxc or VM without editing a .conf in nano?

You don't need to pass the igpu, you just need to give the LXC access to render and video groups, but yes, editing the conf is easiest. I originally wrote out a bunch here, then remembered there is a great video.

https://www.youtube.com/watch?v=0ZDr5h52OOE

My Synology NAS is mounted to the host, but making mount points to the lxc doesn’t actually connect data

Do they show up as resources? I add my mount points at the CLI personally, this is the best way imo:

pct set 100 -mp0 /mnt/pve/NAS/media,mp=/media

This is done from the host, not inside the LXC.

Does your host see the mounted NAS? After you added the mount point, did you fully stop the container and start it up again?

Edit: You can just install curl/wget/etc BTW, its just Debian in there.

apt install curl

Edit 2: I must have glossed over the mount part.

Dont add your network storage manually, do it through proxmox as storage, by going to Datacenter > Storage > Add, and enter the details there. This will make things a lot easier.

https://tteck.github.io/Proxmox/ this is a good place to start. Also highly recommend youtube videos lots of good stuff there.

[–] jjffnn@feddit.dk 6 points 1 month ago

Tteck is unfortunately no longer with us.
The new proxmox scripts project can be found here.

[–] LazerDickMcCheese@sh.itjust.works 1 points 1 month ago (1 children)

Yes, I tried a couple of those. They were giving me errors

[–] jjffnn@feddit.dk 6 points 1 month ago (2 children)

The linked repository is unmaintained, and some of the scripts are broken as a result.
The scripts have moved to this repository.
Last time i used then they worked fine.
Try the scripts in the new one, and if they still give you errors let me know and i'll be happy to try and help you.
Also, please don't run scripts from the internet without reading trough them first. Even from a trusted source. You never know what random people could have written in there. 😅

[–] irmadlad@lemmy.world 2 points 1 month ago (1 children)

Can confirm. The scripts in the new repository work just fine. I've run a bunch of them.

[–] LazerDickMcCheese@sh.itjust.works 3 points 1 month ago* (last edited 1 month ago) (1 children)

I was struggling with it for a bit, but I got it working. Main concern (before I check transcoding/acceleration) is NAS file sharing. Huge headache. The host is connected, but the lxc and vms don't use it

[–] jjffnn@feddit.dk 1 points 1 month ago* (last edited 1 month ago) (1 children)

May i be so bold as to ask about how much experience you have with linux?
A basic understanding would go a long way i think.

But to answer your question:
You need to mount the nas drive directly to the lxc running jellyfin, not to the proxmox host.

[–] LazerDickMcCheese@sh.itjust.works 2 points 1 month ago (1 children)

Probably hundreds of hours, but very little was in a functional desktop...most of it was trying to get an install to boot and update software (I'm not joking).

[–] jjffnn@feddit.dk 1 points 1 month ago

That sucks. But this is a good way to learn.

[–] LazerDickMcCheese@sh.itjust.works 1 points 1 month ago (1 children)

Any tips on copy-pasting those commands into a console window? Every function I've tried has failed, but I'm willing to keep trying

[–] jjffnn@feddit.dk 1 points 1 month ago (1 children)

It always works for me to just paste with ctrl+shift+v directly in the terminal window of the web gui.

[–] LazerDickMcCheese@sh.itjust.works 2 points 1 month ago (1 children)

Interesting, what browser do you use? Sounds like I may have to switch from Firefox if that's the case because this lack of quality of life is ridiculous

[–] jjffnn@feddit.dk 1 points 1 month ago (1 children)

I use firefox as well, on linux mint, not windows. So if you use windows, that may be the culprit. I haven't used it in a long time so i don't know if that could be the case.

[–] LazerDickMcCheese@sh.itjust.works 2 points 4 weeks ago (2 children)

Well, this is the first step in me eventually dropping Windows (assuming all goes well). I'd like to wipe my main PC and do a dual-boot situation eventually, but migrating services to an actual server takes priority...got kiddos counting on their cartoons, can't let em down

There is a helper script for jellyfin LXC. From memory I can't help much, but I suggest searching for that. I think the default specs for disk space and RAM were weak, But setup was easy enough. After the initial helper script, you will need to learn how to mount the NAS into the LXC as well.

[–] ryokimball@infosec.pub 1 points 1 month ago (1 children)

I want to say iGPU makes things easier, not because of experience but only because I tried passing through an Nvidia card and the instructions all insinuated this was more difficult than any other option

[–] curbstickle@anarchist.nexus 1 points 1 month ago* (last edited 1 month ago)

If youre going LXC, its not going to matter much of you just map GIDs and provide the LXC access to the host.

Side bonus, multiple LXCs and they can all share that GPU. This is what I do, I have a couple of JF instances among other containers that use the GPUs.

Edited to add: Well, nvidia itself can be a pain. But that'd be because nvidia.
