Emby Server Running on Debian 11 Errors After Synology 7 Upgrade

[yodajones 3]

@LukeSorry about the old screenshot, but I think it is the same as todays.  See attachment.  The error logs I posted this morning are also from today.

 

[Luke 37132]

The log you provided is not from the same time as that activity entry occurred. Can you please provide the one from when the problem was experienced? Thanks.

[yodajones 3]

@LukeIf you mean a log from 1/9/2024 1:59:59 AM there is none.  I see only 8 logs.  Here is what I see (attachment), unless I should be looking somewhere else.  If you want one of the ones shown let me know.

 

[Luke 37132]

It would be the one that contains the date/time that you see in that error entry in the activity log.

[yodajones 3]

@LukeHere are 2 from this morning and a screenshot of the error in the dashboard.

I would make sure the server has full write access to the folder

/var/lib/emby

and everything underneath. Please let us know if this helps. Thanks.

[yodajones 3]

@LukeDo you have a recommended command?  Maybe this:

chown emby:emby /var/lib/emby

How can I see who / what the permissions are currently before I make changes?

@Lukeand @TMCswHere is what I get from the ls command so it doesn't look like a permissions issue unless I'm reading this wrong.

[Luke 37132]

Have you checked recursively?

[yodajones 3]

@LukeI had not, but I just did.  That was a long list.  Do you want to see the entire output, or only some particular parts?

Here is an example:

root@emby:~# ls -laR /var/lib/emby

/var/lib/emby/root/default/Music:
total 16
drwxr-xr-x 2 emby emby 4096 Nov 20  2022 .

[Q-Droid 657]

Try these two commands.

find /var/lib/emby ! -user emby -ls

find /var/lib/emby ! -perm -u+w -ls

 

[yodajones 3]

@Q-DroidHere is what I get:

root@emby:~# find /var/lib/emby ! -user emby -ls
  1574204  65964 -rw-r--r--   1 root     root     67547136 Dec  2 16:38 /var/lib/emby/data/library.db.backup
  1574240  65964 -rw-r--r--   1 root     root     67547136 Dec  2 16:45 /var/lib/emby/data/library.db
root@emby:~# 
root@emby:~# find /var/lib/emby ! -perm -u+w -ls
root@emby:~# 

 

[Q-Droid 657]

That explains why Emby couldn't write to that DB. Those files should be owned by emby, not root. Stop the emby server, change ownership of those files to emby:emby then start the server.

 

[yodajones 3]

@Q-DroidShould I only change those files, or is there any reason I shouldn't do the entire file tree as such:

chown -R emby:emby /var/lib/emby

 

[Q-Droid 657]

Changing those two files would be faster but either way would have the same result as those two are the only files under that path that are not owned by emby.

 

[yodajones 3]

@Q-DroidSome success! - I ran these:

chown emby:emby /var/lib/emby/data/library.db
chown emby:emby /var/lib/emby/data/library.db.backup

And afterwards some of my libraries are working.  What I can now read and play are "Movies", "Audiobooks" and "TV Shows".  For some reason "Music" and "Recordings" are not able to scan their respective libraries.

Here is the FSTAB

This library works and I can play files from this share in Emby:
nas:/volume1/Video/movie /media/synologynas/movies nfs rsize=8192,wsize=8192,timeo=14,intr

This library does not work and Emby says it is empty:
nas:/volume1/Music /media/synologynas/music nfs rsize=8192,wsize=8192,timeo=14,intr

This library works and I can play files from this share in Emby:
nas:/volume1/Video/shows /media/synologynas/shows nfs rsize=8192,wsize=8192,timeo=14,intr

This library works and I can play files from this share in Emby:
nas:/volume1/AudioBooks /media/synologynas/audiobooks nfs rsize=8192,wsize=8192,timeo=14,intr

This library does not work and Emby says it is empty:
nas:/volume1/TV /media/synologynas/tv nfs rsize=8192,wsize=8192,timeo=14,intr

Inside Emby here are the libraries I have setup:

Working:

Audiobooks:
/media/synologynas/audiobooks
FSTAB Line:
nas:/volume1/AudioBooks /media/synologynas/audiobooks nfs rsize=8192,wsize=8192,timeo=14,intr

Movies:
/media/synologynas/movies
FSTAB Line:
nas:/volume1/Video/movie /media/synologynas/movies nfs rsize=8192,wsize=8192,timeo=14,intr

TV Shows:
/media/synologynas/shows
FSTAB Line:
nas:/volume1/Video/shows /media/synologynas/shows nfs rsize=8192,wsize=8192,timeo=14,intr

Not Working:

Music:
/media/synologynas/music
FSTAB Line:
nas:/volume1/Music /media/synologynas/music nfs rsize=8192,wsize=8192,timeo=14,intr

Recordings:
/media/synologynas/tv
FSTAB Line:
nas:/volume1/TV /media/synologynas/tv nfs rsize=8192,wsize=8192,timeo=14,intr

The playlists are also not working.  These are music playlists I created inside Emby and have the path: /var/lib/emby/data/playlists.  I presume they do not work because the music library is not working.

Just after posting this I looked at the logs and saw this:

Access to some of the media is still not working. Compare a path that works to one that doesn't to see what's different about them both on the Emby server host and the Synology NAS.

Pick some media items of each and compare the full paths, every directory along the way to the files and the files for ownership and/or permissions differences. Every access setting for those on Synology and how they look on the server. Something is different somewhere.

It's the only way to get to the bottom of this.

[yodajones 3]

@Q-Droid& @Lukeand everyone else who helped me out with this.

I want you guys to know that it looks like everything is working again!  I really appreciate you guys taking the time to help me.

To summarize: I had a completely working Emby Server running on a Debian virtual machine on a Proxmox server.  After updating Synology DSM from 6.x to 7.x I noticed that I could no longer view any videos or listen to any music via Emby in a browser or on the Emby app on our AppleTV.

The Synology NAS is where all our media files are stored and were attached to the Emby Server via NFS shares.

There were two significant steps that helped me for my situation:

1. Fixing the permissions on /var/lib/emby/data/library.db and /var/lib/emby/data/library.db.backup with these commands:

chown emby:emby /var/lib/emby/data/library.db
chown emby:emby /var/lib/emby/data/library.db.backup

After running these commands I was able to access some of our shares.

2. Fixing the Squash settings on the Synology NAS.

The original Squash settings on the Synology NFS shares was set to "Map root to admin" and changing this setting to "Map all users to admin" fixed the shares.

After doing these two things I was able to watch videos and listen to music again in the Emby AppleTV app and in all the browsers.

Obviously the permissions for the library.db and library.db.backup files could not have been changed from a Synology DSM update so I probably messed them up with my attempts to fix the original access issues.  Perhaps all I would have needed to do was change the Squash settings on the Synology but I'll never know now.

I have a couple questions remaining, one may be off topic and one could be related:

1. Music Playlists.

Before this all started, I had created some extensive music playlists.  The library shows the playlists are located at /var/lib/emby/data/playlists so are stored locally on the Emby Server.  Now all the playlists are empty.  Here is an example of one of my playlist.xml files:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Item>
  <Added>3/5/2023 11:47:11 AM</Added>
  <LockData>false</LockData>
  <LocalTitle>Pop</LocalTitle>
  <SortTitle>Pop</SortTitle>
  <RunningTime>0</RunningTime>
</Item>

I would have expected to see some of the songs listed in here.  Isn't that a correct assumption?  Why would this playlist.xml be empty now?

2. Media Images.

In the library settings there is a checkbox "Save artwork into media folders".  OK, that makes sense.  But if this is NOT selected where are the images saved?  The reason I ask is because all the images I previously had are now gone.  I was able to "Refresh meta data" and that seemed to get most back, but some were manually set and are now gone.

Again, thank you to everyone here for their help.

It is displayed in advanced library settings.
