Change permission on folders for Jellyfin in Ubuntu

[Worldrazor]

I've been trying to get Jellyfin to access my library, but it won't. I think I have narrowed it down to being a permission issue. I've tried to use the command 
chown -R :lxc_shares /mnt/nas but without luck (it dosen't change anything). I have followed this guide (https://forum.proxmox.com/threads/tutori...es.101795/) to set up shares in my LXC. So basicly I think I need to change the ownership of the directory to the group where the jellyfin user is, but I don't know how.

The permissions for the folders look like this:

root@jellyfin:~# ls -l /mnt/nas
total 0
drwxrwx--- 2 100000 110000 0 Feb 12 13:48 Downloads
drwxrwx--- 2 100000 110000 0 Feb 11 20:03 Movies
drwxrwx--- 2 100000 110000 0 Jan 26 04:18 TV-Series

With network shares you need to provide a UID and GID in the mount parameters that correspond to the owner of the files on the NAS side.

I'm running it in a Proxmox LXC btw.

It's mounted like this: mp0: /mnt/lxc_shares/nas_rwx/,mp=/mnt/nas which should have rwx permissions
It's mounted on the host like this //111.111.11.111/Jellyfin /mnt/lxc_shares/nas_rwx cifs _netdev,x-systemd.automount,noatime,uid=100000,gid=110000,dir_mode=0770,file_mode=0770,user=pveuser,pass=PASSWORD 0 0

I have created a Group with the id 10000 where the jellyfin user has been added

You can see your library on the command line, but jellyfin won't read it, correct?

root@jellyfin:~# ls -l /mnt/nas
total 0
drwxrwx--- 2 100000 110000 0 Feb 12 13:48 Downloads
drwxrwx--- 2 100000 110000 0 Feb 11 20:03 Movies
drwxrwx--- 2 100000 110000 0 Jan 26 04:18 TV-Series

If that is the case, I think in the ubuntu you need to chown the library path so that jellyfin owns it or is the group owner and not 10000:11000.  Since the mount parameters will translate a lot of that.

I have already tried that with this command: chown -R :lxc_shares /mnt/nas

Also tried changing the group name to ID instead, but it dosen't change the permissions for the folder

What are the permissions on the host system?

I fixed it! I created a new LXC and made it unprivileged. That apparently made the change
