Post 10.11.x upgrade: library scans take days now (instead of minutes)

[Iacov]

hey

I have a strange issue with my library scan. ever since I upgraded from version 10.7 to 10.11.(0/1), my library scan takes between two and three days to complete. during the migration, I followed the instructions and first let the database migration finish, then performed a full scan of the library — which took three days.

now, however, every subsequent library scan (scheduled every 12 hours) also takes two to three days, and I don’t know how to fix the problem. Is there an option for advanced logging so I can see why the scan is taking so long? Maybe it's getting stuck somewhere?
My library hasn’t changed, but I suspect the "Home Media" library might be the issue — it contains thousands of photos and small videos. It’s possible the scan is getting stuck there. Unfortunately, I can’t temporarily exclude this library from the scan — I can only delete it, right?

Do you have any advice for me, please?

many thanks in advance!

you can try to ignore the directory from the scan by adding an empty file named ".ignore"
it should ignore the whole directory from a libraryscan, but somewhere back in my head i think i read somewhere that people currently got problems with ignored folders...
but.. give it a shot. should not cause much trouble - in case something goes wrong, just remove that file.

dankeschön, ebenso

i'll try that but will also try to narrow down the "culprit" by scanning the libraries individually and hopefully which one causes the holdup
i know that movies/series are quite fast - music, home media and collections still have to be tested

currently, i'm facing the issue that i have "stopped" the media library scan, but it is still attempting to stop the process (15m+)
very weird as i have absolutely no clue what causes the bottleneck (cpu is a n100 and has pletty of resources left)

I've noticed library scans take longer since updating, but not it's not days)

I had endless issues, I found (not ideal) but just uninstall, wipe it all out. Install the newest version and its now blazing fast. Giant library scans are so so much faster. But before fully uninstalling and wiping out all server data, it was insanely slow after updating an older version. Constantly crashing also.

Sadly only fix was a fresh start with Jellyfin. Hopefully helps! Altho maybe not the ideal answer.

Another alternative to try, make sure there are no stray .nfo files or anything for missing content. Some said that was causing endless loops in searching.
