Upgraded to DSM7/PackageCenter before reading this forum, all libraries gone, please help

[me_duginov_com]

Hi, all

I’m not an experienced Plex user and I didn’t follow this forum before
For years I enjoyed Plex on my Synology DSM 6.
Two days ago it asked me about possible upgrade to DSM 7. I confirmed and upgraded.
Immediately after that Package center told me Plex requires “repair”. I confirmed to.
It gave me a single message: “installation was successful!” and I granted permissions to PlexMediaServer (to the share “media” where all media is stored).

However when I access my Plex server, it now has no libraries. I suspect nothing was really migrated from “Plex” share. How do I fix this?

Regards,
Dmitry

Server Version#:1.29.2.6364-7000

Dmitry,

If everything still remains in the Plex shared folder, we can fix this.

Here is the FAQ, with screenshots.

You will most likely use “Scenario 2”

1. Give PlexMediaServer “Full Control” of all folders and files in the Plex shared folder.
2. Stop Plex
3. Uninstall + Erase the DSM 7 package installation (the empty one)
4. When you reinstall the DSM 7 package, it will be “Installing” until all migration is completed.
   ( Open another tab to the DSM desktop and look for “Migration.log” in the “Plex” shared folder. This will allow you to follow its progress. )

FAQ 27 - Migrating an existing PMS from DSM 6 to DSM 7 Upgrading PMS from DSM 6 → DSM 7 DSM 7 no longer allows us to go find the metadata directory and use it across volumes before starting PMS (This is the lack of “root” privilege blocking). As such we require the following two conditions are met we will attempt to automatically migrate you; You have an existing DSM 6-created PMS installation and PMS is installed on the SAME STORAGE VOLUME as the “Plex” shared folder (this is critical) …

Thank you very much! That helped and I got all my libraries back.
I noticed that here and there I’m missing some thumbnails. Is there anything I can/should run to get them back or it’ll be taken care of eventually by a newly installed version?
Also few libraries now have “Upgrade library” options. Would you point out to some documentation that describes what is that about and whether it’s critical to upgrade.
Thanks again,
Dmitry
P.S. I always granted Plex “read only” access to the actual media folder. Can I keep it this way or it now requires read/write?

Refresh metadata is the best way to get these back. It will generate what’s missing.

Now that you’re on the new server, you also have the new media agents and scanner at your disposal.

If your names are per plex standard, you can upgrade and you’ll notice how much faster things work

Plex only needs Read access to your media unless you want to record DVR.

Thanks again!

One more wrinkle. In a web client I now can see two servers with the same name, one is not accessible (presumably old one?), another one is good. How can/should I get rid of the dead one?

Dmitry,

1. Open Plex/web
2. Settings → Authorized Devices (Upper Left corner)
3. Change “All” → “Server” (it’s a dropdown box)
4. You will see the empty server DSM created (which we deleted from the hDD)
   – AND -
   See the one migrated to DSM 7

Look carefully at the ‘Last Seen’.

The current one (migrated one which is still running) will have been seen more recently than the dead one.

REMOVE the dead one
