Write permissions with docker -> cifs mount > synology nas setup

[Xinv9 0]

I'm struggling with the write permissions for my Emby server. It runs fine, except for the write permissions: nfo, srt, pictures are not saved after a refresh and an error is reported in the logs (attached) immediately after I try that. The strangest thing is that I did succeed in getting delete permissions: I can delete videos from Emby. 

I've already checked File Permissions Guide for New Linux Users. And read multiple posts of people having similar problems, but that didn't help me so far.

I'm running Emby in a docker, the docker-compose is run from uid:1000:

version: "2.3"
services:
  emby:
    image: emby/embyserver
    container_name: embyserver
    volumes:
      - /home/snip/emby:/config # Configuration directory
      - /mnt/nas_video:/mnt/video # Media directory
    ports:
      - 8096:8096 # HTTP port
      - 8920:8920 # HTTPS port
    devices:
      - /dev/dri:/dev/dri # VAAPI/NVDEC/NVENC render nodes
    restart: unless-stopped

etc/fstab:

//192.168.1.16/video /mnt/nas_video cifs user=###,pass=###,vers=3.0,auto,noperm 0 0

Without the noperm only root had write access, so I figured this would help. If I go into the mount with uid 1000 I have write access, but it didn't give me write access for Emby.

 The mount is to a file share on Synology. The user that has the mount, has write access for the shared folder.

I've tried adding this to the docker-compose.yml (even though this doesn't seem right, running as root), but that doesn't change anything.

    environment:
      - UID=0 
      - GID=0

Hi, please see if this similar question here helps:

Thanks.

Thank you. Unfortunately this doesn't help me. That other question is also not solved by the way. It did help me with the correct statement to exec into the container, but once there I can do everything write/delete, without a problem. Also in the mounted folders. But the Emby-error persists.

Hello,

I had the same problem on a Debian 11.

The only solution was to upgrade to the Emby beta.

Sincerely

Hi, it's due to a bug in the .NET runtime, and the upcoming 4.7 server release has updated to .NET 6, which resolves this.

Aargh, this indeed solved the problem, tnx @focheur91300. Well at least I learned a lot about Docker and permissions...
