Plex not auto scanning media

You’re describing what happens when you have more folders than DSM can monitor without slight customization.

To verify.

  1. DEBUG server logging on, VERBOSE logging off, SAVE if changed
  2. Restart PMS
  3. Wait 3-4 minutes (give it time to finish initialization)
  4. Download the logs ZIP file
  5. Open the ZIP and inspect “Plex Media Server.log”
  6. Search for ‘No space left on device’ . It’ll occur on a ‘Notify’ event record.

If this is the case, follow this procedure.
