I recently updated the firmware on my NAS to 4.3.6.0979.
When running PLEX Media Server version 1.15.4, when I add libraries, it does not recognize any of the files in the paths added to it.
I tried upgrading manually to PLEX Media Server version 1.16.0, but after doing that, I cannot access the server at all, I just get a 404 error.
After uninstalling, reinstalling 1.15.4, the 404 error continued… uninstalled and reinstalled again, and it loads again, but I’m back to the libraries not finding any files.
Check your path permissions and same for a few files. Betting the NAS permissions changed when PLEX upgraded. There are a few posts about it, sorry I can’t find it a the moment
The “MultiMedia” share isn’t a real share. It’s an application which runs on QTS and artificially creates what looks like a share.
It is convenient for most because it does the work of sorting media types
It doesn’t work for Plex because it isn’t consistent in how it interacts.
The best solution here is for you to:
EDIT each Library section and add the shares which contain your actual media (direct reference), e.g. /share/movies, to your library section
When Plex is done detecting them this second time, they all will indicate with a 2 (number of duplicates)
Now Edit one last time and remove the Multimedia share reference.
This time, The duplicates will be removed as Plex updates the locations
When complete. Plex will now have the exact path and be operating independent of the Multimedia share.
Scan files
Empty Trash
Clean Bundles
Optimize database
The MultiMedia share has always been a problem. Every time it updates, everyone is impacted. Everyone loses their media until it scans again… All their watch history is gone and there is nothing we can do about it.
@ChuckPa - To clarify a little (and I’m no expert regarding how QNAP’s built-in software works, so I’m not entirely sure if this makes a difference) I have the ‘Media Library’ on my QNAP disabled. I found early on that it seemed to be a resource hog, so I just disabled it, as I planned to use PLEX for that anyway.
So I don’t think any of the QTS multimedia stuff is a factor. I did continue to use the Multimedia share as the primary share on my first disk, since it was already available. Do you think that’s still a problem? It’s been working fine for me for a couple years now. I only had an issue briefly after upgrading the firmware and the PLEX Media Server app, but it seems to be working fine again now. If I were going to use a path such as /share/movies, I’d have to create a share at that location, as it doesn’t currently exist, and then move all of my files to that location.
The Multimedia share is an artificial share. It is a software API entirely.
We went through the debugging process over several weeks here in the forum.
Two things it doesn’t support which Plex needs for proper operation:
Kernel change notification
File locking
To add to this, Codex Pack updates will cause the Multimedia database to be reconstructed (reindexed). When this happens, you lose all your media because, as far as Plex is concerned, it’s gone. When re-indexing is complete, Plex will scan again, as if new.
Please do take our advice seriously on this. Use the Multimedia share for QTS apps without issue. Use the share directly (/share/share-name). /share/share-name keeps you in Linux and out of the MultiMedia Console app.
