Season Unknown

[Jamie Chapman]

After upgrading to 10.11.x (I took the plunge with 10.11.2), the fix for me wound up being:

• Temporarily remove the offending media (move the entire show out of the root "Shows" folder)
  
• Perform a full library scan to allow Jellyfin to remove the show from the database
  
• Add the media back and perform another full scan
  

This was 100% successful for me. None of the TV shows have Season Unknown after the process (about 30% of my shows had the season unknown issue). I did the above steps by removing all shows that had the season unknown issue, running a full scan, then adding each show back one at a time, with full scans after adding each back. Obviously not pure science, as I was looking for the least impact on my time. YMMV.

Note: My "upgrade" to 10.11 was in actuality a clean install, not an upgrade. I blew out my old 10.10.7 database and metadata after backing it all up, in case 10.11 was still being problematic. I had attempted numerous real upgrades from 10.10.7 to 10.11.0 release candidates, and all of those upgrades had slowness issues that I could not resolve. The clean install method on 10.11.2 worked really well.

With the clean 10.11.2 install, everything has been running great, except for the unknown seasons issue which I finished cleaning up late last week using the above procedure (I had upgraded to 10.11.3 when I did the above procedure, in case it matters, which it could)

Some things are still a little bit slower than they were on 10.10.7, Books and Music libraries specifically, but overall the system is performing much faster for me with movies, TV shows and Collections, with fewer errors in the logs.
