nfo Metadata saver: Permission denied

[chrischalfin 0]

Hi,

I am having this problem for a while now and tried to find the solution in former topics facing with file/folder permission issues in Linux. I think I tried a lot, but still without success.

What am I trying to do?
I want to save all metadata changes, made within emby, saved as an album.nfo file in the album-folder. I just want to make sure, that all changes I made are permanently saved and can be exported when necessary.

My library setup
My music is physically stored on a network drive, which is configured as a samba share. I mount this share with a dietpi-raspberry and emby is running on that raspberry. I checked file permissions, the mount has owner and group emby. So that should work?

What did I do so far?
I activated nfo as metadata reader and safer in the library. I change the album genre in emby and save it. My expectation is, that this change would reflect in an album.nfo file? But nothing happens.

Log Output
This is what I get:

My question:
What could possibly still go wrong? I know everything looks like a classic linux permission problem, I just already tried many configurations with no luck. Is there another cause for this problem? Or am I missing something else?

I hope you can help me Thank you!

HI there, it looks like Emby Server is being denied write access by your file system. Have you taken a look at this?

Thank you for your reply! I already found that article and followed the instructions. Unfortunatelly It didn´t solve my problem.

My current permission status for my music library is the following:

drwxr-xr-x  2 emby emby  0 Aug  8 20:50 MusicLibrary

The user emby should have write permission. Maybe it´s important to know, that the folder is mounted via samba share and the following entry in fstab:

//192.168.178.XX/MusicLibrarySamba /mnt/MusicLibrary cifs cred=/var/lib/dietpi/dietpi-drive_manager/mnt-MusicLibrary.cred,iocharset=utf8,uid=emby,gid=emby,file_mode=0755,dir_mode=0755,vers=3.1.1,nofail

The corresponding configuration in smb.conf is the following:

[MusicLibrarySamba]
path=/media/myCloudDrive/music
writeable=yes
valid users = SambaUser
force user = sambauser
force group = sambauser

The music folders permission settings:

drwxr-xr-x 1 sambauser sambauser  144  8. Aug 21:50 music

One possibility is, that maybe the different user names emby and sambauser might cause the problem?

Amazing! Thank you @Happy2Play, that solved the problem. This kept me up for a very long time now, next time I will post my issues earlier

I thought that would have been fixed in .Net 6. Go figure.
