If someone can help me fix this please new to Plex and unraid servers.

[JaysPlex]

I don’t know if this your problem but a power outage is probably at the top of the list for things that cause database corruption

Can you access the Plex UI at all?

You should probably post a full set of logs to see if that’s what the problem is
There is a repair utility if that is the issue

GitHub - ChuckPa/PlexDBRepair: Database repair utility for Plex Media Server...

I'm having issues with a corrupt database

Unraid Plex runs via docker. Run the tool inside the container. e.g docker exec -it container bash then , inside the container, you’ll be root and the tool will detect the container configuration.

I think I saw Chuck say he’s not going to be around today so if you need assistance you might have to wait a bit

[chrishern66]

Thanks I will look at this and see if it helps. No worries on time its been down for 2 days now.

[ChuckPa]

If there are problems with Preferences.xml, it’s not a DBRepair problem (yet) .

It’s this problem

You’ll need to reclaim it without erasing all the ID’s .

I have the tool for that

1. In container; stop plex (plex_service.sh -d)
2. Fix preferences.xml
3. Restart

Given the file is empty – you might have to delete it completely,
Get a new PLEX_CLAIM token
Recreate the container – using the same directory bindings so you don’t lose the metadata.

GitHub - ChuckPa/UserCredentialReset: User Credential Reset utility for Plex

[chrishern66]

Sorry not sure how to get in the container to stop plex. Is that from the unraid WebUI or console? Somone else made this for me and they are no longer around.

[ChuckPa]

To get in and out of docker as well as control PMS in it is easy.

1. Start the container
2. use docker exec to get into the command line
3. inside the container, run the plex_service.sh script (see below) with the -d (down) option.
4. PMS will now stop
5. Next, with the UserCredentialReset.sh script placed (usually where /config maps to in the real file system), run it.
6. Observe it knows it’s inside the container

This is what i see plex is running

I can open this.

and click console.
none of the commands work here.

[ChuckPa]

That really differs from what I have.

I don’t know whose image that is.

Plexinc is this, and I have control.

[chrishern66]

I get this

should i type something different?

[chrishern66]

[chrishern66]

[chrishern66]

i can open terminal but get this when i try to run docker exec
Thanks for your help

[chrishern66]

Docker container list pops up here

[chrishern66]

I’m getting somewhere i stop PMS

but UserCredentialReset.sh does nothing

Thanks for your help.
I just did this and it is back up fine now.

Linux/Plex preferences.xml failed to load

Had an unfortunate reboot caused by circumstances out of my control and upon startup, getting the same error from plex. Running 1.25.6.5577 . Preferences.xml is now a completely empty file. Is this a widespread issue? edit: resolved by moving the empty Preferences.xml file out of the default dir, running setup again using 32400/web. Thankfully this did not alter plex data for libraries at all, just the home screen.
