Files in bind mount not visible

[PaulePils]

Hello,

recently, I decided to change how my NAS should work (VM with OMV ---> LXC with Cockpit) to make better use of the shared folders/files/mount because I wanted an arr-Stack. I found these awesome Tutorials Tutorial bind mounts and ZFS bind mounts. I got it to work except for the Tdarr LXC...... (I used the tteck script to create this LXC, all the rest was build manually).
I used the same mount point, the same group, usermod etc. but I still can't see the files inside the directory. Jellyfin, Cockpit, Sonarr, Radarr, .... all work with this group mapping config

Chown and chmod both give me an error message that even the root user of the lxc is not allowed to change something

root@tdarr:~# chown -R :raid-users /mnt/
chown: changing group of '/mnt/media/movies': Operation not permitted
chown: changing group of '/mnt/media/music': Operation not permitted
chown: changing group of '/mnt/media/tv': Operation not permitted
chown: changing group of '/mnt/media/books': Operation not permitted

Here the permissions structure from the PVE host

ls /raid/media/ -all
total 35
drwxrwxr-x 6 raid raid-users  6 Nov 23 17:49 .
drwxrwxr-x 7 raid raid-users  7 Nov 21 23:23 ..
drwxrwxr-x 2 raid raid-users  2 Nov 23 16:56 books
drwxrwxr-x 9 raid raid-users 10 Dec 24 13:20 movies
drwxrwxr-x 6 raid raid-users  6 Dec 17 16:54 music
drwxrwxr-x 9 raid raid-users  9 Dec 17 15:43 tv

and here from the Tdarr LXC

ls /mnt/media/ -all
total 7
drwxrwxr-x 6 tdarr  raid-users    6 Nov 23 17:49 .
drwxrwxr-x 3 tdarr  raid-users 4096 Dec  1 00:20 ..
drwxr-xr-x 2 nobody nogroup       2 Nov 21 23:19 books
drwxr-xr-x 2 nobody nogroup       2 Nov 21 23:20 movies
drwxr-xr-x 2 nobody nogroup       2 Nov 21 23:20 music
drwxr-xr-x 2 nobody nogroup       2 Nov 21 23:20 tv

Here my config of the ARR LXC:

If someone could point me in the right direction I would be really happy

I assume you can't see the files at all. Not sure about this one (I have never done this myself), but I notice:

From arr-Stack config:

mp2: /raid/media/movies,mp=/mnt/media/movies

no trailing slash after dir mp in LXC, so ...../movies & not ...../movies/

but from tdarr config we have:

mp0: /raid/media/movies,mp=/mnt/media/movies/

Is this intentional. I am not sure, Debian vs Ubuntu? Maybe try changing it to the one that works.

I found the trailing slashes as a potential fix in another post. Before it was without the slashes but unfortunatly, both are not working.
I got the same config for LXC of Jellyfin and of Sonarr, ... Those work.

Maybe I try to setup Tdarr without the script
