Please note – before starting make sure you have installed the Container Manager package from Package Manager

When passing folders into a Docker container each mount point is treated as its own filesystem.

This means when moving files between two mount points Docker will do a Copy, then Delete operation. Meaning you are creating a full duplicate of a file while its being ‘moved’ creating unwanted disk IO and temporarily taking up double the space. (especially when seeding torrents after copying to the final folders)

In order to avoid this we need to set up a clean directory structure that allows us to just have one folder or share mounted to our containers.

If you are starting with these guides and have existing media you may need to move around your data in line with this setup, I recommend creating all the folders below using File station to avoid potential permission issues later.

Directory Structure

With this setup all of your media will sit within a single share, you can call this whatever you want but in all the guides it will be called ‘data’. If you change its name you will need to adjust any steps or compose files from my guides accordingly.

Open up the control panel then in ‘Shared Folder’ hit ‘Create’

On screen 1 fill out the name as ‘data’

Screen 2 we leave the folder unencrypted and don’t enable write once features

Screen 3 – Enable data checksums as this will help catch any issues with files during data scrubbing.

Screen 4 – just click next past the summary

On the final screen we don’t need to change any user permissions yet, we will do that in the second guide.

The Sub-folders

Now we have our main ‘data’ directory we need to create a number of sub-folders to hold our media and downloaded files. You can amend this depending on whether you are using Torrents or Usenet (Newsgroups) or both.

You will initially create 3 folders within /data

  • media
  • torrents
  • usenet

Then under /data/media create

  • movies
  • music
  • tv
  • books

Then under /data/torrents create

  • completed
  • incoming
  • watch

Then under /data/usenet create

  • completed
  • intermediate
  • nzb
  • queue

Your folder tree should now look like this.

Finally, within the /docker shared folder create a folder called ‘projects‘ which will be used for any containers using the Projects (Docker Compose) feature of Container Manager.

You can now go back to where you left off in the guides and do the next step.

    I’ve followed your instructions to the letter and have a working system but I get the following error in both Sonarr and Radarr.

    “Download client qBitTorrent places downloads in the root folder /data/torrents/completed. You should not download to a root folder.”

    I dont understand this since I have

    /data/torrents for downloads
    /data/media for shows

    Any ideas of how to fix?

      Hey – if you have set the folders as mentioned then this error should not appear. For the actual ‘Root folder’ within Sonarr and Radarr > Settings > Media Management are they set to /data/media/tv and movies respectively.

  2. Just to let you know, I’m using DSM 7.2.1-69057 Update 5. Your Screen 2 shows a different view, but has the same meaning. Here’s the screenshot

      Hey, you link doesn’t seem to be working, I will do the upgrade and swap out the screenshot 🙂

    Hey, so I have followed all your guides and set this up but the files are not being moved out of the ‘completed’ folder to the TV folder after they’ve been downloaded. Sonarr is saying it doesnt have access to the ‘data/media/tv folder. The root folder in Sonarr is the data/media/tv and it can read whats in there.

    Been trying to figure out and a lot of guides say that they usenet folder should have a ‘movies’ and ‘tv’ folder in it so that sonarr knows where to put the downloaded items. But I have no idea! I have clearly missed something when it comes to permissions, but no clue where.

    • Dr_Frankenstein Dr_Frankenstein

      Hey is the path missing the initial /

      The completed download folder doesn’t have to have dedicated tv and movie folders, but it does help.

      Drop me a message via my HelpMe! page and we can exchange some screenshots.
