Problem to browse/save in a Docker mounted folder

[EHRETic]

Hi there,

I'm scratching my head with one...

So I have 2 SABnzbd Docker instances, one test, one "productive".
The test one is just to test updates and config modifications.
Both runs today 4.5.5 (11ba9ae)

On these docker instances, I mount 2 folders.
Those 2 folders are NFS shares mounted on the physical host and I pass them in compose file.
One is used as "upload" default and the second one contains subfolders for categories (movies, series, music). Both have the same permissions.

Here is how I declare them:

Code: Select all

    volumes:
      - config:/config
      - downloads:/downloads
      - /mnt/sabnzbd:/mnt/sabnzbd
      - /mnt/uploads:/mnt/uploads

On the test instance :
- default upload : no problem
- second categories folder : no problem, I can also see & browse folders from web console when I edit a category.

On the prod instance :
- default upload : no problem
- second categories folder : can't be browsed from web console and I get this error when I download a movie :

Code: Select all

Traceback (most recent call last):
  File "/app/sabnzbd/sabnzbd/filesystem. py", line 741, in create_all_dirs
    os.mkdir(path_part_combined)
PermissionError: [Errno 13] Permission denied: '/mnt/sabnzbd/Films'

The weirdest thing: from container shell, I can browse and create folders without any issue and this was working a couple of months/week ago.
(but I can't figure out if this is due to a SABnzbd update or not... and this doesn't explain why one instance would work and the other not.

Any clue where I can start looking please?
