DSM 7 - Plex Media Server 1.24.3.5033 - Recent upgrade and then half movie library was deleted

Server Version#: 1.24.3.5033
Player Version#: n/a

I have a Synology 920 which was recently upgraded to DSM 7.0-41890, then I deleted my previous version of Plex Media server and installed “PlexMediaServer-1.24.3.5033-757abe6b4-x86_64_DSM7.spk” which was downloaded directly from the Plex/ downloads page.

I did the installation and reset the libraries to refer to my existing folder structure:

multimedia

  • movies
  • music
  • tv

I followed the directions and allowed R/W access to the multimedia folder to the Plex internal user account.

When clicking on Movies or TV Shows, initially nothing showed up.
Then I did a rescan of each library and the movies showed up with a garbage can over many of the movie titles. I did a test and clicked on a few and the movies played. Because it was a “new” install, I decided to reboot my NAS and then let the system settle and do its regular maintenance overnight.
Today I logged in and the libraries were empty! I rescanned and the TV Shows and Movies started showing up. But when the scan was completed, I lost nearly half my movie library (from 796 movies down to 400 in the library, 409 in the movies folder). I have checked the system recycle bin but the missing movie files are not there.

I haven’t checked the TV Shows or Music folders, but I do know I am missing movies. :frowning:

Questions

  1. Any idea how to restore these movies?
  2. Is thee a log files indicating what was deleted?
  3. Where do I restore them from?
  4. What setting do I need to change to prevent movies from being deleted going forward?

FYI: I have backups to different QNAP NAS on-site, and an off-site backup to an AWS Glacier bucket - but I wanted to check to see if I could retrieve these files locally before bringing them back from the alternate NAS.

Any assistance is appreciated.

Thanks

I have reset the file permissions. Essentially nothing changed, but I went through the motions as noted from trmps81’s reply to my initial question.

I will wait to see what happens.

But… my original questions still apply:

attached is the zipped log file. Logs.zip (6.7 MB)

To clarify a couple items:

  • the movies that were deleted where single files under the movie folder, there were no subfolders deleted
  • I double checked and “Allow media deletion” is unchecked

Thanks for your assistance.

Thanks for your assistance trumpy81.

I will get started doing some maintenance and restoring from backup the rest of my movie collection.

Cheers
