It will sit there “Processing”… This is normal & expected.
If you already indexed a lot of media… don’t worry
What the app is doing is automatically upgrading the internal storage from the Beta structure to the final structure (You’ll have a PlexMediaServer shared folder when this is done with your server & metadata having been relocated there)
Not knowing how much media you have, this could take a couple minutes to an hour or so.
Don’t panic.
My advice is to sit there, on that page, and don’t navigate away from it (DSM won’t show you what it’s doing if you do)
There is a “PlexMediaServer” username (internal to DSM)
-and-
There is a PlexMediaServer shared folder.
You will grant System Internal User (the application) permission to read your media files.
At no point should you need to touch anything in the PlexMediaServer shared folder unless you need to get the logs manually or want to add a special preference to Preferences.xml
PlexMediaServer is “MY” shared folder for the app’s use
Its checking the library now. I’m not sure if its working as of yet. I clicked a video to see if it worked and it did not. Could be the library is not up to date.
For you, since it’s all in the Plex share, you only need to fix that one shared folder
and “Apply to this folder, sub-folders and files” (an important step) – you’ll see the checkbox as you do it.
