HINT: I have also submitted this as an issue in Github. You can see more detailed logs and screenshots there:https://github.com/jellyfin/jellyfin/issues/13278
I'm experiencing an issue where my Jellyfin server fails to completely scan my media library. After I hit the "scan all libraries" button, it produces isolated episodes but the whole season does not appear in my anime library. It also fails to recognize some of the anime in my media folder - neither complete season nor isolated episodes appear. Note that all these files are maintained automatically by Sonarr, so they are neatly named and organized and Jellyfin absolutely should have recognized them.
When I dived further, I found that Jellyfin automatically cancelled the scanning process shortly after it was started, amd that the scans will eventually stop at 86.6% with a log output
After stopping at this point for a moment, the whole scanning process is terminated. It seems that Jellyfin is trying to delete a phantom season but it is stuck, and that the rest of the library is not scanned at all. Meanwhile, another interesting fact is that SOMETIMES the scanning process stops after an error:
Through my observation, I believe that this error ONLY appears when the scanning process is the FIRST scan after the server is (re)started and the following ones do not report any error. The following ones will get stuck, and then exit, with incompletely scanned libraries, but no error in the log file. I know that poor accessibility to metadata providers such as TMDB here in China can be a cause of incomplete scans, but I have already disabled all means of scraping metadata (because the metadata is maintained by Sonarr) so this is definitely not the reason. I don't know why this error appears randomly, and I'm not sure whether it is related to the incomplete scan or not, but something must have gone wrong in my Jellyfin database.
Has anyone else encountered this problem? Are there any known fixes or troubleshooting steps I can try to resolve this issue?
Thank you for your assistance.
