Refresh metadata stopped working

[Coert000 0]

I can use some help with Refresh Metadata on my libraries. 

Since I installed Emby a week ago, it worked like a charm.  Today I installed the People backup/restore plugin and the Refresh Metadata stopped working.  I have the library set to use .nfo file, but none appear.  The only thing that I notice are error reports in the log as show below

Synology 216j (DSM 6.1.7-15284 Update 3) and the stable release of Emby (4.5.4.0-6)

Hi there, please attach the complete emby server log.

Additionally, please provide some discussion of an example. thanks.

Thanks for the reply @Luke.  

I noticed that nfo files were not written when the metadata was refreshed.  This gave me the impression that metadata was not being refreshed at all.

Reinstalling the Emby server didn't help.  I tried re-adding the media library, but still no luck.  Finally, the The "permission denied" in the log pointed me in the right direction.  I noticed a difference in permission between the Linux-based host file system and its SMB file sharing that uses Windows ACL permissions.  I now see the nfo files appearing.

I am still in the dark about all the " *** Error Report ***" entries in the log.  I tried running the command from a shell, but it seems like should runs in a .net container or so.

I attached the log you asked for.

Yes the system is trying to save the nfo files but being denied write access by your file system:

	System.UnauthorizedAccessException: System.UnauthorizedAccessException: Access to the path "/volume1/audio/Compilations/80s/album.nfo" is denied.

So resolve that and I think you'll be good to go after that.

Thanks. Yes, it seems to have a good go at it.

What about the other error reports from ffprobe?  I suspect it might be related to UTF-8 file names or so.  Or just let it go?

[Luke 37116]

That's actually from the Dlna feature. Can you temporarily enable debug logging under the server debug logs section, as well as dlna debug logging under the dlna settings? Then maybe we can find out which device on your network is sending messages across the network to cause that. thanks.

Will do.

Great, thanks !

The DLNA was right on.  I still had Plex running advertising over DLNA.  Since I disabled Plex, I no longer see the error messages.

Thanks!

Thanks for the feedback.
