Edit: Solved! Thanks a ton non_burglar.
Good day selfhost gang!
I’m redoing my media stack and I’ve come across a conundrum that I can’t solve on my own. I’ve got Docker containers on the same Debian machine for qbittorrent, sonarr, and radarr for automatic media downloading. The problem is, as you may have guessed from the title, I need to implement remote path mapping in sonarr/radarr because qbittorrent downloads to a different location than where my media files are hosted. My media is hosted on a network share, mounted at /home/marighost/gilashare/media (which is further broken into subfolders for media types). On this machine, however, I’ve got my qbittorrent downloading to a 2Tb SSD at /srv/data/torrents. Here are the volumes as presented in my compose.yml files:
qbittorrent:
volumes:
- /home/marighost/docker/seedbox/gluetunconfig:/gluetun
- /home/marighost/docker/seedbox/qbittorrentconfig:/config
- /srv/data/torrents:/data/torrents
sonarr:
volumes:
- /home/marighost/docker/arrstack/sonarrconfig:/config
- /home/marighost/gilashare/media:/tv
- /srv/data/torrents:/data
radarr:
volumes:
- /home/marighost/docker/arrstack/sonarrconfig:/config
- /home/marighost/gilashare/media/movies:/movies
- /srv/data/torrents:/data
All three applications work mostly as expected (radarr can grab a release from an indexer, throws it into qbittorrent to download), but it does not move media into the /gilashare subfolder.
Obviously, I get the error in both sonarr and radarr that tells me:
You are using docker; download client qBittorrent places downloads in /data/torrents but this directory does not appear to exist inside the container. Review your remote path mappings and container volume settings.
Here is how my remote path mapping looks in the settings of sonarr/radarr:
Host: qbittorrent
Remote Path: /srv/data/torrents/
Local Path: /data/
I was messing around with radarr initially, and also tried appending /movies to the ends of the Remote and Local paths to see if it needed the full path, but that didn’t seem to work either. I’ve also read through Trash Guides, but the information there seems outdated (all references to images are just… not there). I’ve also read radarr’s docs, but I feel like I’m missing something, and they just link to Trash Guides anyway.
Thanks for reading, happy to dig into my configs or setup more if necessary.


No worries, and I’m glad it helped!
I’ll add that I was also mystified by the remote path option for a long time, I think the wiki should show more clearly what this does and maybe an example.
Also, I used to run into issues of running into permissions errors because the download client wrote the files with the wrong permissions. Many nzb and torrent clients have a POSIX masking option that allows you to set the permissions at the time of writing.
