Hey all, I’ve got ZFS pool created and just create a VM drive in that pool like normal, then Jellyfin just has that drive mounted. I think I’m losing the best parts of ZFS through this manner.
How should I set this up properly? Create a media pool or something and have VMs accessing the pool directly?

So if you’re going through the trouble of setting up proxmox, I would setup the majority of the storage in a ZFS pool for a TrueNAS SMB share/NFS share. Then create a small container just to host jellyfin and jellyfin’s cache–maybe commit 10GB of storage to it–really depends on how big your media library is. Mine is about 5TB and cache, metadata, and other misc things take up about 8GB.
Setting up your share is enough for jellyfin. Since the media and jellyfin are stored on the same metal, additional latency will be sub 100ms. Create a library in Jellyfin and set it to the share;
Movies: \\nas\Movies,TV: \\nas\TV, etc.Works flawlessly and would have more utility than allocating the entirety of your storage to your jellyfin container because it functions as a normal NAS. I’ve been running with a setup like this for a while and it works great.
Are you suggesting creating a TrueNAS VM? Wouldn’t that be the same as what I’m doing now with creating an image in the ZFS pool?
If you want to share storage you need some way of doing that. Zfs is a good option for storage on vm-host level, but ist not designed for shared usage. Im not sure what you are after, but maybe you want zfs storage inside the vm for snapshots, dedup etc? Or maybe you want to share your media storage between vm’s? The first case you can use zfs inside your vm, it does not know or care about how its disks are stored or of they are a physical drive. For the second use-case you want some way to share drives, like smb, nfs etc. or a distributed filesystem if you really want to over complicate things. Truenas might be over overkill for sharing a few volumes, but you need something. I believe you can share zfs over nfs now but i have never used that outside of proxmox cluster storage
I use both debian on a vm with samba+nfs and a bare metal truenas for my needs. Find your needs and figure out what solves them
Why bother with truenas? Just put the media in a zfs pool and mount it directly into jellyfin.
You’re doing it fine. You can overprovision your zpool that way for other VMs with datasets on the pool, and it only uses what it needs for each set. And you can exclude the media pool from backups and repllications if you like. There’s no performance hit the way you’r doing it.
I sure wouldn’t bother with any sort of NAS intermediary, you can share out the media pool via the Jellyfin VM if you really need to, but I can’t see why you would if you’re using Arr stack components already.
OK, sweet thanks. I just thought having the media files directly in the ZFS pool (zfs pool > files) instead of ZFS Pool > Qemu img > Files would be smarter
Then you’d have to share them back from the host to the guest using NFS or samba, and there’s no reason to have them on the host. No, you’re fine. That’s what I would consider the right way to do it for what you describe as your purpose. Putting more layers in there isn’t serving a useful purpose, which is why I say to not bother with a NAS to store them, if your primary use of them is via the Arr stack VM.
