Since some recent update, I wasn’t really paying attention but it’s been about 45-60 days maybe, odd things have been happening with my Home Screen on either my AppleTV or my girlfriend’s Roko. It looks like the database isn’t fully being read or loaded? Where I’ll have hundreds of shows - it’ll suddenly show only several dozen, with sporadic episodes listed. I can rescan the library and they’ll show up. And over the course of a couple of weeks the Recently Added list will show items that had been loaded for years.

So, obviously it feels like a database issue. But when I do an integrity_check with Plex SQLite it says all fine. And rebuilding the database seems to have no effect.

Since this is happening seemingly at random I don’t know where to begin looking in the logs.

Is this some bug introduced with a recent update? Did I anger a bog hag? Do I need to make a sacrifice to some forgotten deity? What should I look for in the logs or try next to try and find more clues or a solution…

I have over 1100 movies in the directory Plex is using for the Movies category. But only 500 or so shown. When I force it to scan it sees the full catalog, but at some point it’ll reverts to the 500+ movies as before. It’s not a case of it showing all the movies but some don’t play - it’s forgetting about the movies it just added. And it seems like this is happening regularly. It’ll constantly show me TV Shows and movies that I’ve had for years as if I just added them (meaning it forgot about them and just re-added them). This is getting very frustrating. Collections and playlists I create are useless because the videos I’ve added get removed when Plex forgets about them.

Might be this:

I’d peruse that thread to see if it fits what you’re seeing.

Good Luck,

Okay, trying this again. The video files are not going anywhere on my storage. The database is forgetting they even exist. One day I’ll have 1100 movies, then next day I’ll have 30. Happens for TV Shows and Movies, not one specific category.

I don’t think it’s a file system issue - Movies and shows aren’t listed but can’t be played due to missing media. Instead I think it’s a database issue - a movie that was listed yesterday is missing entirely from the user interface the next. Movies and Shows will slowly reappear when rescanning, but they show as just added when it was rescanned (not when it was initially added years ago - at least before I trashed my entire database).

I can re-scan and eventually all my movies and shows will show back up… until they disappear again!!! Collections that were complete one day, now show zero items and I have to go back through and reselect items to be in a collection again (they don’t automatically go back into the collection they were in before they disappeared).

I trashed my entire plex database and rebuilt it from scratch. Worked great for a couple of weeks. Now I’m back to forcing it to rescan every couple of days.

Running the plex database check and it says everything is fine. Which is the same answer the captain of the Titanic gave.

I am facing the same issue. I had my QNAP fail due to a motherboard issue. Thankfully, all files were backed up to a Lacie big2dock. I added the new path, however, on a “scan library file” the old files are “unavailable” (which makes sense), but the new files are not being found. I had the empty trash can checked, so once scan was done the “unavailable” files disappeared. Now out of around 1000 movies, and maybe 3700 Music albums, I am seeing only 50 or sometimes 70 files. A rescan of the library causes files earlier visible to become “unavailable” whilst new files show up. I dont mind starting from scratch to rescan everything, so pls help guide me on the steps.

  1. if your media files are not stored inside the Plex server machine, never activate “Empty trash automatically after every scan”. This prevents them from getting removed from your plex database when they’re not available. And thus it will prevent them from getting re-added and appear as “recently added” when they become available again.
