ERR: MigrateMusicBrainzTimeout

Hey everyone,

so now I got time to take a deeper look into the problem and was able to solve it.

First of all I checked my database file which was located here ( I use UnRaid + Jellyfin docker):

Database location:
/mnt/user/appdata/jellyfin/data/data/library.db

First I opened the database:

Code:

sqlite3 library.db

Then I checked its integrity:

Code:

PRAGMA integrity_check;

It came out, that the database was borked. 
Luckily there were 2 other library databases (backups obviously automatically generated by jellyfin during the last docker updates) in that folder:
  library.db.bak1
  library.db.bak2

So I did the PRAGMA integrity_check also on those two databases. It came out, that library.db.bak2 was borked, but library.db.bak1 was ok.

So I deleted the following borked databases.
  library.db
  library.db-wab
  library.de-shm
  library.db.bak2

Then I moved library.db.bak1 to library.db and started Jellyfin Docker again and it worked. 

Code:

mv library.db.bak1 library.db

Jellyfin automatically recreated the databases library.db-wab and library.de-shm new.

PS: You in case need to make sure that the database file has the right owner. Just check your other jellyfin files and change that in case. E.g.: When I copied the database, it create the new database with owner root:root. To change this into another owner just:

Code:

sudo chown jellyfin:jellyfin /mnt/user/appdata/jellyfin/data/data/library.db

In this example the new owner would be jellyfin:jellyfin, but in my case it was users:?.

And: Once again thanks to TheDreadPirate for his frequent supply here!
