I have created some "custom" TV shows to accumulate groups of related miscellaneous videos. The TV show format, with season sub-folder organization suits my purposes perfectly. The main folder for each show is titled "SHOW NAME"; Sub-folders are "SEASON 1", "SEASON 2", etc; Naming of episodes are "SHOW NAME - S#E# - episode title", and are all within their respective season folder. Of Course, they can't be IDENTIFIED because they don't exist in any online databases (IMDB, TVDB, etc). I go back & edit the metadata, and tick the "lock to prevent future changes" for the show, seasons & episodes. It's a bit of work, but the final presentation works very well for me. When I first started with Emby these shows were acknowledged, but with no automatic assignment of metadata or images (as expected). Some I was able to manually edit & they were fine. Unfortunately, some were a bit "mixed up" due to sloppy file naming conventions on my part. In order to correct the problems I moved the entire folder to a separate, non-indexed shared folder on my NAS using File Station, then went into Emby (Version 4.8.10.0) & deleted the show (to eliminate any "incorrect" data related to the title), then went back to File Station on my Synology NAS (DS718+, DSM 7.1.1-42962 Update 6) and edited the file names, folder names & show titles to consistently match the structure & naming conventions I mentioned above. When I moved the entire corrected folders back into the DOCUMENTARIES folder (indexed under Emby for TV Shows), the shows were no longer recognized - they fail to show up in the TV show list at all. Individual shows have an option to RESCAN FILES, but I can't seem to find that option for the TV show section as a whole. I tried clicking the Refresh Page link in my browser address window ↩︎, and then tried completely closing the window & restarted Emby from the Home Page on my NAS, to try to force it to re-scan the indexed folders. The shows still don't show up in the list. I have seen Emby take a little time for changes to show up, but I have been re-checking (& refreshing) Emby while writing this post, and after at least 1/2 hour they are still not showing up. I thought, perhaps, having deleted the shows might prevent them from being re-recognized, but one of the shows was renamed completely, so that can't be the issue.. Is there a way to "force" Emby to recognize new added content when it fails to do so own its own?

It is a per library setting but per your log it does not work as iNotify has to be modified. System.IO.IOException: The configured user limit (8192) on the number of inotify watches has been reached, or the operating system failed to allocate a required resource. As for manual scan you have many options. Scheduled task manually trigger library scan, or add additional triggers at different times. Manually Run from Library page Manually scan the library Manually scan the Series Get the libraryids and use the api/script to scan.
