Library malfunction and new shows not populating

[adman99]

I'm running Jellyfin 10.11.6 on Windows 11 pro, and, as of this afternoon, I've had an issue where nothing I copied into my "TV Shows" library would be added to the server. I could, however, get expected results from adding the media to other libraries. I've moved everything from my D:\MEDIA\TV SHOWS directory to a new folder, deleted the old, and moved everything back. Now, I'm showing two ghost libraries that don't exist on my home screen, none of my devices can access any TV shows, it looks like the new library was deleted from the dashboard, and I'm at a loss.

I went back to server version 10.10.7 & it works fine now

I'm having a very similar issue. Saturday everything was working fine. On Sunday transferred new files to my TV Show and movies directories. The movies updated fine but the TV Shows never updated. I tried messing with settings and even went as far as deleting the TV Shows library and crating a new one and now none of my Tv Shows exist in jellyfin. One post on another forum thinks the jellyfin database has become corrupted but I can't verify that in any way.

Similar problem. since yesterday my jellyfin Television media folder won’t see any newly added shows. New episodes of shows with folders already established are seen fine - just brand new ones are somehow skipped.

It’s just TV shows that has this problem, new films are seen fine in movie folder. If I place new TV shows in another media folder, Jellyfin sees them and populates the metadata fine, however if I copy them back to TV folder jellyfin is still blind to them.

I’ve tried renaming the files, remuxing them, adding established and viewable into the new folders (which become immediately invisible), copying the new mkv file into established and viewable folders where still they aren’t viewable

I'm not not sure if it coincidental but I upgraded my UGreen OS yesterday too.

any ideas?

I don't think its a UGreen issue because I"m running my server on a stand alone Ubuntu machine

Thanks Gary. I too created a new TV library - it was identical to the original in that it saw all previous TV shows but none added since tuesday. However, I didn't delete the old and reboot. So perhaps it was working on muscle memory.

Until a fix is found, my work around is a library I created for things that are neither films or TV shows. This folder (set to host mixed film and TV) sees the TV shows fine.

Before I made the above post I was able to see error logs for tv shows I'd tried to add by their titles. However I don't seem to be able to recreate those logs with new additions. Here are some errors in the log at the moment. Maybe they help identify the problem.

I am considering a database reset. An attempt to rebuild the library structure again from scratch. In Config: deleting db files, then recreating the libraries.

Might this work?

Has anyone done this before?

I was going to copy the config files just in case, should I take any other precautions?
