[SOLVED] Cannot Read Mounted SMB path on RHEL9

[ayrus02]

Hi, I have problem, my Jellyfin setup is on old PC running AlmaLinux 9, the setup was run perfectly. But recently I've tried to add new library to read some mounted SMB Shares on other machine.

Bellow are the error log from Jellyfin when I've tried to browse the path to mounted SMB shares:

Code:

FYI: I've run the mounting of SMB Shares using root user. Is there anyway I can enter some console using user of Jellyfin to verify that Jellyfin can access (read) the path and it's content?

Is there anyway I can enter some console using user of Jellyfin to verify that Jellyfin can access (read) the path and it's content?

if it's installed in docker

docker exec -it jellyfin /bin/bash
- (replace jellyfin with the name of your container)

if it's not in a docker
# su jellyfin
(replace jellyfin with the username for jellyfin)

OK, thanks for the help, I've resolve this problem by adding these options on mount command of SMB Share

Code:

uid=961,gid=962

and Jellyfin flawlessly can read the SMB share folder.
uid 961 is for jellyfin user in my server and gid 962 is group for jellyfin on my server. You can see what UID and GID for your jellyfin user by running this command:

Code:

# id jellyfin
uid=961(jellyfin) gid=962(jellyfin) groups=962(jellyfin),39(video),998(render)

Thanks to all of you for the help provided...

Regards.
