I lose my tags and metadata every time Plex refreshes

Server Version#: 1.14.1.5488
Player Version#: 3.77.4

My Plex server seems to want to refresh my entire library every few days. I cannot figure out how to tell it to stop doing this. It takes FOREVER for it to refresh and while it’s doing it, for some reason, half the movie library disappears. The movies will inevitably reappear but it might take a whole day for Plex to refresh all the metadata (even though I don’t want it to go through this cycle).

Every time it goes through this, I lose all the tags I had manually inserted and all the collections that had been created (like linking a series of movies together, for example).

I can’t go through this whole process again, where I have to enter all this information into Plex, only to lose it in about a day when it decides to do it’s own refresh sequence.

So…anyone else experiencing this issue? How can I tell it not to refresh the whole library every day or so?

do you have something set in Scheduled tasks? https://support.plex.tv/articles/201553286-scheduled-tasks/

Yes, it does some scheduled tasks. I’ve unchecked a lot of items. I’m not sure what it’s doing that causes it to essentially refresh all the data. I have over 600 movies in my database and when this process starts, I can visibly see movies disappear until the total gets down to just over 200. Over the course of 12-18 hours (sometimes longer), it slowly builds back up to the total number of movies. But in the process, the alternate posters I’ve selected have been removed and many movies that have custom tags to create collections are removed. I have to reinsert them all over again, but then lose them (AGAIN) the next time Plex goes through it’s refresh cycle.

It’s maddening. I have a screenshot of my settings but don’t see a way to attach a photo.

To add a photo, it’s the upload icon to the right of the one that looks like a rubics cube. Looks like a computer with an Up Arrow.

Thanks…uploading image…for now, I’m shut down my server. After running all night and still not done refreshing, I cannot have the server taking up all my CPU computing power.

In addition to losing tags and updated posters, bonus features (for movies that have them) no longer show up. So all the work to save and upload bonus features goes for naught. I can likely force Plex to find these files again and get them to show up, but that is the real problem…I keep having to redo all the work and Plex keeps screwing it up and just creating more work for the end user. There has to be a better solution out there.

let’s start from the beginning.

  1. what type of library is this? is it happening to more than one library?
  2. are your media files stored on that same computer the server runs on?
  3. what agent is the library using? which sub agents are enabled and in what order for it?
  1. This is a movies library. Doesn’t seem to be happening in other libraries but my other libraries are small and other media, such as TV Shows.

  2. Media files are stored on a 4TB WDMyCloud drive that is connected to my wifi network.

I’m attaching pics of the agents I’m using and the order. This is for Movies. Perhaps this is causing the conflict. Plex doesn’t allow me to unselect “Plex”, “Personal Media” or “The Movie Database” options so I have to figure out how to prioritize them to get the right results.

those look fine. if you go to edit your library it will show which is being used on the advanced tab ( images below)

it sounds like the server is loosing connection to the MyCloud (not sure if it goes to sleep or anything), during a scan it thinks the media is gone and removes them, then as the NAS wakes up it adds them all again as if brand new. I am wondering if you turn off “empty trash after a scan” in library settings it might stop that. (that setting removes data for files it can no longer find after a scan)

I don’t see that setting in the screenshots you attached.

regarding the WDMyCloud…it definitely does go to sleep but don’t most hard drives?

I really don’t know what is going on, I just know that I’ve manually entered in data for some of these files too many times to do it again. If I can’t get to the bottom of what’s happening, I’m going to have to find another way to access this media.

Also, can you give me any insight as to why, when it does refresh, it doesn’t recognize all the of the bonus material that is in these folders? The files are structured according to Plex rules and it has recognized them before. But when it goes through this refresh cycle, it’s like it ignores all the bonus material. I have to go to each movie that I know has bonus material and force a manual refresh of metadata for it to recognize it. It doesn’t always work right away either and of course, it forces me to keep a memory of all the movies where I actually have bonus material, which is obviously not practical.

the “empty trash after every scan” is a server library setting. those previous screens were for you to look at what agent is being used for your movie library.

yes most drives go to sleep but a drive on a NAS to be pinged then wake which could take some time for the computer to see depending on network speed, etc (to be clear i am not saying that is the cause, it was just a guess about what might be happening)

as far as the bonus material. assuming you do have it named right since manual refreshes pick it up fine. I can’t say why it would not in the first place. Can you tell me an example of how you have them named/organized for one movie and i can try to reproduce

I’m using conventional Plex naming. As I stated, last night before the server decided to refresh the whole library, all my bonus material was visible. When the refresh started locating and re-adding movies to the library, the bonus material didn’t show up.

As an example of my naming:

(Folder) Crimson Tide (1995)

  • Crimson Tide.mkv
  • (Folder) Interviews
    - Denzel Washington-interview.mkv

my main issue is that when the library is reformed, the extras don’t show up, unless I force a metadata refresh
