Unable to load root folders

[fahadshery]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I can see all my movies INSIDE the container.
I can also write to the /movies folder from INSIDE the container.
But I am unable to import my existing movies.
I have been using the same movies folder for few years without any issues.
This is what I see:

and this is the error I see when try and import:

Expected Behavior

Being able to import my existing movies.

Steps To Reproduce

Just spin up the docker and portainer.
Then setup using docker compose

Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

I can also write to the /movies folder from INSIDE the container.

You're likely exec'ing into the container as root, but radarr runs as user abc inside, which is mapped to the PUID/PGID you set in docker arguments

Yes and that PUID and PGID is mapped to my user which can read/write/execute in the /movies folder.

Here is how I am mounting the cifs share:
//192.168.10.90/media /mnt/nas/media cifs uid=1000,gid=1000,credentials=/home/myuser/.smbcreds 0 0

[Mafyuh]

I am having same exact issue. everything still works, adding new movies, importing from download client, literally everything besides seeing root folders and importing movies manually, ive tried downgrading versions the past few weeks, and still the same. I can delete movies still from the ui. I only set up this VM about 6 weeks ago and everything was fine then. I guess i havent tried to manually import since then so I'm not sure when it started.

My fstab for mounting:
//ip/share-name/Media /data/media cifs username=username,password=password,uid=1000,gid=1000,auto,nofail 0 0
Ive tried re-running some permissions commands:
sudo chown -R $USER:$USER /data
sudo chmod -R a=,a+rX,u+w,g+w /data
My PUID/PGID are set same as above docker compose. I'm just mapping /data:/data

I am getting the same exact error message as well.

Docker version 26.0.1, build d260a54
Ubuntu 22.04.4

EDIT: Updated to Ubuntu 24 with docker version 26.1.0 and its fixd

[alexneth]

I have also encountered this issue. Updating to Ubuntu 24 and docker 26.1.0 like mentioned by Mafyuh above, did not work for me. The only way I managed to get this to work was to set both PUID and PGID to 0.

[thespad]

That means you have permissions issues, which you're bypassing by having radarr run as root, which we neither recommend, or support.

I am getting a similar error, except trying to add a root folder says it has invalid permissions.
My compose:

  radarr:
    image: lscr.io/linuxserver/radarr:5.7.0.8882-ls228
    container_name: radarr
    restart: unless-stopped
    environment:
      PUID: ${RADARR_PUID}
      PGID: ${PGID}
      UMASK: ${UMASK}
      TZ: ${TZ}
    networks:
      - proxy
    volumes:
      - radarr:/config
      - data:/data

When I try adding a root folder:

Unable to add root folder

    Folder '/data/media/movies/' is not writable by user 'abc'

Yet, /data/media/movies has the following permissions:

truenas1# ls -ld movies
drwxrwxr-x  2 nobody  arr  2 Jul 10 17:20 movies

The arr group is the same as ${PGID}, confirmed by the logs:

───────────────────────────────────────

GID/UID

───────────────────────────────────────

User UID:    10023

User GID:    90075961

The container sees the permissions as such:

drwxrwxr-x 2 nobody abc 2 Jul 10 17:20 movies/

Which if abc is mapped to the PUID/PGID then this should be fine.

So I'm unsure what to do...

[sonicd007]

I'm running into the same issue. abc user has 1000 as PID and GID and I confirm the directory has the same permissions from within the container but abc is unable to write to the directory.

Assuming this is a USB drive, it's mounted as root, the device needs to be mounted and the folders need to be owned by the uid/gid you're using.

[sonicd007]

I was able to resolve the issue on my end by changing the docker container's directory mapping to /data/media instead of /media. I think since /media is already a directory in Linux this may have been causing issues with the mount. Once changed, the /data directory is owned by root but the subdirectories are owned by user abc and thus I can write/read to those directories.

The mounted media is an nvme disk drive on the host machine just fyi.

So two ways to solve this, either change the mount directory within the docker container or docker exec -it radarr /bin/bash and chown the directory you want chown abc:abc /media.

A third alternative might be to create your own image based off the radarr image where you can do the chown command there so it's automated but I would say just change the mounting directory on the container.

[sonicd007]

Nevermind, I thought that solution worked but it didn't. I still have to chown the directory for it to work

[sonicd007]

Last update, I think the issue is that within docker compose the abc user will only have access to the mounted directory NOT the entire path to the mounted directory. I had to change my volumes like so

volumes:
      - /media/sonicd007/Media/radarr/data:/config
      - /media/sonicd007/Media/media/:/data/media/
      - /media/sonicd007/Media/media/download-client-downloads:/downloads #optional
      # - /media/sonicd007/Media/media/movies:/data/media/movies #optional
      # - /media/sonicd007/Media/media/tv:/data/media/tv #optional

Doing this lets user abc access the /data/media root directory for the general media setup settings and then I can add the movies and tv directory under the libraries section of radarr. This seems to work for me.

[j0nnymoe]

It just sounds like your ownership of the folders isn't setup correctly if you're needing to chown.
