Automatic scan starts and stalls

Plex Media Server
1

I have “Run a partial scan when changes are detected” set. None of the other automatic scanning options are checked.

When I add a file to TV programs (say) and go to the home page and click on the dots next to TV programs I can see “Cancel scan”, so I know a scan has been initiated. But this scan will never actually run; I have to cancel it and then “Scan library files” to actually see the new video in the library.

Same for new media added to any other library folder. The files are obviously detected, and the library shows “Cancel scan”, but I have to cancel and run manually to see it.,

Is this a known issue or is there some other setting I need to change?

I think when I was starting with Plex I can remember something like this. But that was more than 7 years ago. My process for adding and scanning files has changed a lot since then.

Can you describe how you’re adding the new files? Could it be that the file transfer is slow and Plex is stalling because the file is still being written as the scan is performed?

Can you try copying the file to the destination drive, but somewhere Plex can’t see. Then move the file to the library folders, as that should be instantaneous. See if this scan still stalls.
