[Bug] jDownloader not working with NFS mounted download folder

[ozdeadmeat]

Anything else?

I am using this in a Portainer Stack.

[ozdeadmeat]

have also attempted to use

- "/usr/downloads:/downloads:rw"
as another volume with the same result.

Directory perms are set correctly and can write to the directory, as far as I can tell, it appears to be an issue related to the app itself not registering the drive locations as writable.

[ozdeadmeat]

Can download to /tmp though not ideal

[jlesage]

Looks like a permission issue. Can you share the output of:

docker exec <container name> ls -ld /storage

Also, could you share the configuration of the associated export from the NFS server ?

[ozdeadmeat]

when in a container shell i can write to all the directories just fine. It seems to be only related to the java application.

[jlesage]

when in a container shell i can write to all the directories just fine. It seems to be only related to the java application.

Executing command from the shell is done as root. So any permission issue might not be seen.
Instead of doing touch test.456, try su-exec app touch test.456.

[jlesage]

Also, please share the export from the NFS server so we can see if it can explain the problem.

[digitalextremist]

I am also available to help diagnose this. I have this issue on three machines, with Mint Linux 21.*

[jlesage]

Sharing this information would be useful:

• Your NFS export.
• How you mounted the NFS share on the host.
• How you created the container (the docker run config).

[elec2]

Same here with a SMB share.
I can r+w files with the container cli but jdownloader says "invalid download directory"

docker-compose.yaml

version: '3'
services:
  jdownloader-2:
    image: jlesage/jdownloader-2
    ports:
      - "1131:5800"
    volumes:
      - "/docker/jdownloader-2:/config:rw"
      - "100_DOWNLOADS:/output"

volumes:
    100_DOWNLOADS:
      driver: local
      driver_opts:
        type: cifs    
        device: //192.168.1.3/100_DOWNLOADS
        o: "username=jdownloader,password=xxx,vers=3.0"

The SMB Server output should not be relevant because it is already working as "root" out of the container.

[jlesage]

What is the group and ID of the jdownloader user you used for the volume ? Looks like this same user should be defined via USER_ID and GROUP_ID environment variables.

[elec2]

If I understand that correct, that would mean, I'm never able to mount and use other SMB accounts in linux but only my own linux account login name. 🤔

[jlesage]

Sorry, small confusion on my side.

This line o: "username=jdownloader,password=xxx,vers=3.0" should include the user and group ID that match USER_ID and GROUP_ID environment variables.

So if USER_ID=1000 and GROUP_ID=1000, then your line should looks like:

o: "username=jdownloader,password=xxx,uid=1000,gid=1000,vers=3.0"

[Darkxaser]

I have the same problem, is there already a solution or is a solution in the works?

Thank you very much

[jlesage]

Please share:

• Your NFS export from the server
• How you mount the NFS share on the client

Sorry, small confusion on my side.

This line o: "username=jdownloader,password=xxx,vers=3.0" should include the user and group ID that match USER_ID and GROUP_ID environment variables.

So if USER_ID=1000 and GROUP_ID=1000, then your line should looks like:

o: "username=jdownloader,password=xxx,uid=1000,gid=1000,vers=3.0"

Finally I had time to test this and it worked indeed. Thank you very much!!!

had a similar issue with SMB CIFS like #160 (comment) and your proposal solved it as well as for #160 (comment).
Thank you very much for your support!

Ok... same part of the game, another problem.

I switched to another SMB server and now jDownloader says "skip download - Disc full".
This time it seems like it's not a permission problem.

I can manualy write files with the console as root and also app user. But if I do df the SMB volume is shown as "tempoarily unavailable"

Idk what I'm doing wrong here.
Here is the docker compose... where nothing has changed besides the smb server ip and login.

version: '3'
services:
  jdownloader-2:

    volumes:
      - "/docker/jdownloader-2:/config:rw"
      - "jdownloader:/output"
    restart: 'unless-stopped'
