PLEX Creating duplicates of all my music without end

It looks like you have snapshots enabled, and Plex is picking up the files in the snapshots.

I did a quick search on the forum.

See this post: Scan results in hundreds of duplicate items in Music Library - #18 by Kubjo

After you get Plex to stop scanning snapshots:

  1. Re-scan all libraries
  2. Empty Trash
  3. Clean Bundles

dance


Then:

  1. Stop Plex Media Server
  2. Wait one minute
  3. Start Plex Media Server.
  4. Wait three minutes (to fully start & log everything).
  5. Pull & post the log files.

Scanning the snapshots is causing some other issues. It should resolve itself by not scanning the snapshot folders, but need to double check.

The Notify errors mean you’ve exceeded the number of directories Plex can monitor (you’re not really out of space). Not scanning the snapshot directories should bring you below the limit. If it does not, it is easy to fix things: FAQ 16: Increase the number of folders Plex can monitor
