I am a bit confused tbh 😅

The link you send links to docker projects, the link I sent is the second one of those. Seems pretty straightforward?

But to be fair, I have never used docker for any of this. In my nix config, it’s literally just:

    services.prowlarr.enable = true;
    services.prowlarr.openFirewall = true;

There’s not really anything you need to configure host-side. Prowlarr needs to be able to communicate with sonarr and radarr (same as jackett), but otherwise it’s basically stateless.

Hell no, My downloads folder in my media folder are completely different. I copy everything from downloads to media It gets renamed, possibly resampled. The torrents are left in the original folder to seed unmolested.

Every once in a while I go through my torrent list and just tell the client to destroy the torrent and files for anything that I don’t care to seed anymore. Zero chance of it breaking my actual store.

Hard links are a built-in feature of basically every modern filesystem. The bigger question to me is, why aren’t hard links working for you?

Yes - but I have no idea about docker, sorry. Have it running baremetal (or rather, in a proxmox VM).

Just a hunch, but in case you “only” share the directory where Sonarr puts Episode files with Jellyfin via some mount point or whatever, and not the directory where Sonarr gets them from (where the torrent client downloads to), then I can see hardlinks breaking in unexpected ways
