Plex Media Server upgrade to 1.19.1.2630 won't restart

Plex Media Server
1

Server Version#: 1.18.9.2578
Player Version#: N/A

CentOS 7.3.10

Running headless in a CentOS VM for months. Went from 1.13.6.5339 to 1.19.1.2630. Seems like everything updated OK, and when the service fires up, the service just dies and crashes within seconds. Any clues what went wrong? I have many crash dumps if that would be of use to anyone.

Plex Media Server logs are surprisingly quiet:

I suppose it might be helpful for @ChuckPa if you can re-run the installation and post the output from your terminal (either as text or screenshot).

3

Also please post the contents of /tmp/plexinstaller.log ?

Regarding logs being quiet, was DEBUG logging disabled? (turning DEBUG off does not save space)

4

just applied the update and had the same issue on Linux Mint. Plex Media will not restart

Again I ask.

Contents of /tmp/plexinstaller.log and/or the actual console output from when it installed please?

6

/tmp/pms-8c6bca34-82a0-430a-a666-765b5a8a68c8/ file is empty

7

Please rerun the installer. You will not harm anything,
Immediately thereafter, without rebooting. grab the file /tmp/plexinstaller.log
along with any console output.

The console output and the contents of /tmp.plexinstaller.log should match.

You know I have never had to “re-run” an installer, I always just do “sudo yum update plexmediaserver”. So when I run that again, all I get is “No Packages Marked for Update”. If I try to do “sudo yum install plexmediaserver” I just get “Nothing to Do”. Is there a way to force the Plex installer inside the RPM to run by itself?

Thanks,
Erik

Now I understand the disconnect. You’re using RPM packaging.
I’m working on that now to follow what I just completed for Debian.

In that RPM , the new installer will run and perform both the validation as well as reporting back to you everything it found and how PMS is setup.

At this point, with us in sync, may I have a tar.gz of the Logs directory (under /var/lib/plexmediaserver a bit)

10

OK Here’s what I got…
eccoleman-logs.tar.gz (390.5 KB)

11

Also to answer your previous inquiries, I do have DEBUG turned off at the moment, and unfortunately, I rebooted the system before I was able to grab /tmp/plexinstaller.log.

Thanks,
Erik

12

Would you mind manually editing the Preferences.xml file?
Doing so allows us to turn DEBUG logging on again

  1. /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Preferences.xml

  2. Right before the closing /> , add logDebug="1" with a space preceding it.

  3. Save and start PMS.

When it starts next, it will start with DEBUG logging. We’ll see a lot more.

What I can see isn’t promising. It looks like a bad installation:

Apr 08, 2020 09:55:41.557 [0x7fc639ffb700] WARN - Request for plug-in [org.musicbrainz.agents.music] but it doesn't exist.
Apr 08, 2020 09:55:41.917 [0x7fc639ffb700] WARN - Request for plug-in [tv.plex.agents.music] but it doesn't exist.

Normal installation puts these in /usr/lib/plexmediaserver with all the other executables and resources.

This implies a bad download or install.

13

OK done, and new set of logs are uploaded here. eccoleman-logs.tar.gz (409.5 KB)

So taking a different route, would it be safer/cleaner to just save my databases and do an uninstall/reinstall? Haven’t done that before either, but I think if I just do an rpm -e and delete stuff that will freshen everything? Do I need to save anything else besides databases?

Thanks,
Erik

14

Did you edit Preferences.xml with Plex already stopped?

It looks like you did but the length of the log files is only 23 KB. It should be a few MB by the time it gets going.

Erik,

How many Plug-ins do you have? PMS thinks you have 39! the limit is 10.

16

I did have it stopped, a quick glance showed DEBUG entries, so I figured I was set.

As for plug-ins, I’ve never messed with them, I’ve kept things pretty stock. So I’m surprised to see that!

-Erik

17

Would you please go count the number of entries in your Plug-ins directory?
ls -la would be most helpful.

18

Here’s what I got… neither 10 nor 39:

Honestly, none of those look terribly important, we don’t use those channels via Plex at all.

Thanks,

Well… you do know there’s no way to access those which stream content anymore and can be removed?

20

OK So I cleaned up nearly everything in the Plug-Ins folder. There are a few generic ones in there, but seems like it still is crashing as a new log is rotating about every 2 minutes. Here’s the latest batch. eccoleman-logs.tar.gz (401.8 KB)
