Permission problem with Radarr and smb

Solution: Use NFS -_-'

Hello. I've been using hotio's qbittorent, radarr and sonarr images for a while and I've been really happy with it. But A few weeks ago, I started having problems with radarr failing to copy my files to the destination folder. I have qbittorrent on machine A and my video server on machine B (called "orbiter"). I mounted destination folder on machine B to machine A like follow: sudo mount -t cifs //orbiter/Video/ /mnt/OrbiterVideo -o username=root,password=omgstrongpassword,uid=998,gid=100

And added it to fstab: //orbiter/Video /mnt/OrbiterVideo/ cifs username=root,password=omgstrongpassword,iocharset=utf8,noperm,uid=998,gid=100 0 0

Now, here are my docker-compose for qbittorrent and radarr :

QBittorrentVPN

    
version: "3.7"

services:
  qbittorrent:
    container_name: qbittorrentvpn
    image: cr.hotio.dev/hotio/qbittorrent
    ports:
      - 8992:8992
      - 8118:8118
    environment:
      - WEBUI_PORTS=8992/tcp,8992/udp
      - PUID=998
      - PGID=100
      - UMASK=0022
      - TZ=Europe/Paris
      - VPN_ENABLED=true
      - VPN_LAN_NETWORK=192.168.1.0/24
      - VPN_CONF=wg0
     # - VPN_ADDITIONAL_PORTS
      - VPN_IP_CHECK_DELAY=5
      - PRIVOXY_ENABLED=false
      - DEBUG=yes
    volumes:
      - /srv/path/Files/QBittorrentVPN:/config
      - /srv/path/Files/QBittorrentVPN/downloads:/downloads
      - /srv/path/Files/QBittorrentVPN/skins:/skins
    cap_add:
      - NET_ADMIN
    sysctls:
      - net.ipv4.conf.all.src_valid_mark=1
      - net.ipv6.conf.all.disable_ipv6=1
    restart: unless-stopped

Radarr

    
version: "3.7"

services:
  radarr:
    container_name: radarr
    hostname: Radarr
    image: cr.hotio.dev/hotio/radarr
    ports:
      - "7878:7878"
    environment:
      - PUID=998
      - PGID=100
      - UMASK=002
      - TZ=Europe/Paris
    volumes:
      - /srv/path/Files/Radarr/config:/config
      - /srv/path/Files/QBittorrentVPN/downloads:/downloads
      - /mnt/OrbiterVideo/movies/:/movies
    restart: unless-stopped

Radarr manages to grab and download a movie, but it fails to copy it:

    
2023-07-21 16:15:59.3|Warn|ImportApprovedMovie|Couldn't import movie /downloads/awesomemovie.mkv

It is important to note that I didn't change anything in my config.

Is there something I am doing wrong here ? I can't see through this anymore.

What do the permissions look like on newly created files and directories from the qBittorrent container? Run ls -al and check to see, this sounds like a simple fix.
You can try adding file_mode and dir_mode to your fstab mount as well.
https://superuser.com/questions/1359092/whats-the-difference-between-file-mode-dir-mode-and-gid-when-mounting-a-cif
- Folders are drwxr-sr-x and files are rw-r--r--
  I added file_mode and dir_mode in my fstab mount. But should I erase uid and gid as this post mentions that it overrides file_mode and dir_mode ?
  
  I know you marked this as SOLVED, however I just noticed (dunno how I missed it before) that your umask is 022 for qBittorrent but it is 002 for Radar. Even though you have the same UID/GID on both systems I’d still recommend setting 002 umask in the qBittorrent compose file
Does the ending / intervene maybe?

- /mnt/OrbiterVideo/movies/:/movies
Is the share mounted?
Can you browse the mount from source machine?
Can you browse the share inside the docker container? (--interactive)
- The ending / wasn't a problem a few weeks back, but I tried to remove it anyway with no luck. The share is mounted and I can browse it from source machine and container.
  
  Have you set the correct chown permissions? ls -al /mnt/OrbiterVideo/movies
  I have a similiar issue on a plex transcode folder that randomly resets permissions.
I know it's linux and you never reboot it and yadda yadda, but have you tried rebooting both machines?
For what it's worth, that's my fstab entry (it's mounted with a normal user, which is the same which the containers use). I seem to remember I had to change ownership of the /mnt/nasdownload folder (before the mount) to the user used to mount it.
//192.168.1.10/Download /mnt/nasdownload cifs auto,user,uid=1000,gid=1000,rw,iocharset=utf8,suid,credentials=/root/.smbgringo,file_mode=0770,dir_mode=0770,_netdev,vers=3.0 0 0
- I tried rebooting with no luck. Changing my fstag entry following your suggestion didn't work either.
So what do the permissions look like on that file? Does it work if you enter the container as that user and try it yourself? If you have selinux enforcing, have you checked its audit log?
- It has same user:group as files that could be copied before I started having bugs, And that's the user: group I need. I have this problem with multiple files, downloaded at different times, trying to copy them on different locations on my mount. So my guess as a beginner is that the problem is at the destination. I don't have selinux.
