Upgraded 1515+ to DSM7 and Plex not working

Plex Media Server NAS & Devices
1

Hi Guys,

I followed the instructions given in this thread how to upgrade:

But there was one small difference:

  1. Uninstall the DSM 6 Plex app: DONE

  2. Upgrade to DSM 7: DONE

  3. Reboot DSM again after upgrade: DONE

  4. Download Plex (dsm7) from Media Server Downloads | Plex Media Server for Windows, Mac, Linux, FreeBSD and More : DONE (1.25.6.5577-c8bd13540-x86_64_DSM7.spk)

  5. The installer will expect the new username “PlexMediaServer” to already exist and have Full Control of the Plex share. It will not so the first attempt to install will fail.
    This is expected.

=> At this point, the installer did NOT throw any error! (I did not created the user PlexMediaServer upfront), it finished the installation successfully!!

Then I resumed with the actions required (grant access to PlexMediaServer to the shares with my files).

Now the Plex server is shown as offline, checking /PlexMediaServer/AppData/Plex Media Server/Logs/Plex Media Server.log shows issues:

Feb 28, 2022 13:10:30.616 [0x7f2c1751db38] DEBUG - [HttpClient] HTTP/1.1 (0.0s) 403 response from GET http://192.168.178.32:5000/ssdp/desc-DSM-ovs_bond0.xml (reused)

I attached Plex Media Server.log.
Tried to find “Plex/Migration.log” but could not find it?!

Not sure how to fix it, I need help :confused:

Thanks guys.

Your logs show that it started up a fresh DSM 7 installation.

The installer does look for an existing “Plex” shared folder to migrate the data from.
Specifically -

  1. If there is an existing shared folder named Plex (various capitalization allowed)
  2. AND it can look down inside it enough to see a valid “Plex Media Server” folder.
  3. THEN it will start migration

Anything else results in a new/fresh installation.

therefore:

  1. What is the shared folder name
  2. What are the permissions on the “Plex” share ?
3

From my POV, everyhing as it should be

Plex
Plex893×560 96.3 KB

Plex2
Plex21056×474 46.5 KB

Contant of Plex folder:

Plex3
Plex31020×490 58 KB

Did you give PlexMediaServer permission to access the Plex shared folder ?

Yes see picture 1. PlexMediaServer has full control for Plex share.

@braun.th

If it now has Full Control, for all Sub-folders and files

  1. Uninstall Plex - ERASE option to remove the empty DSM 7 setup
  2. Reinstall the package
  3. The installer will automatically engage

Do not interrupt the installer once started.

You may open a new session to DSM and look at Migration.log (after about 3 minutes) in the Plex shared folder to track progress.

Woho - that worked! Thanks, Plex is up & running.

Migration.log shows also no issues:
