Docker Plex Service Kill Command Update (LinuxServer.io)

[AppliedEllipsis]

On the current LinuxServer.io Plex Docker container, the service kill command is now

s6-svc -d /run/service/svc-plex

The path has changed and the current script will fail to stop otherwise.

@AppliedEllipsis

Cool. Thank you for letting me know. I'll update right away. Expect an update (Aug 28/29)

I've never been able to get the script to stop plex correctly (in a linuxserver.io docker on unraid) and the command seems to change every time I need to run it.

Rest of the script is awesome and I've used it multiple times so hopefully this fixes it and the command stops changing.

And reading the install instructions I think I have the files in the wrong spot. They are supposed to be next to /config and mine are in there. Hopefully that is my main issue.

@Chaotic

1. Yes, put the script (DBRepair.sh) adjacent to /config
2. This way, when you enter the container, you can then /DBRepair.sh stop auto start exit (or whatever you want to do)

I just created a new LSIO plex container.

This is what I see:

root@lsioplex:/# ls /var/run/service
s6-linux-init-shutdownd  s6rc-fdholder  s6rc-oneshot-runner  svc-cron  svc-plex
root@lsioplex:/#

Given you state /run versus /var/run, I have no problem adding support for that variant.

Can you confirm?

I've updated the general path testing to look at both older and newer (?) path -- which I can't yet confirm in my own new container.

Please test the DBRepair.sh from this branch

https://github.com/ChuckPa/PlexDBRepair/tree/chuckpa/update-linuxserver-svc

[AppliedEllipsis]

Hey,
Both paths exist in the container, but the command does not actually stop plex unless s6-svc -d /run/service/svc-plex is used.

Testing that branch I get:
./DBRepair.sh: 738: Syntax error: "}" unexpected (expecting "fi")

But adding another fi ~ :664 does allow the script to run and it stops/starts plex in the container successfully.

[ChuckPa]

1, Yes, I forgot to close that with fi

2. If both paths exist in the container, how can we determine which one is the correct one to use ?
   I have then as equal. last-wins, IF statements. I can make a if-then-else tree.

[AppliedEllipsis]

For 2: I am not sure how you would other than maybe try one after the other instead of replacing.

It might have something to do with Docker Read-Only Root FS and s6
https://github.com/just-containers/s6-overlay#read-only-root-filesystem

Note that s6-overlay assumes that:
/run exists and is writable. If it is not, it will attempt to mount a tmpfs there.
/var/run is a symbolic link to /run, for compatibility with previous versions. If it is not, it will make it so.
In general your default docker settings should already provide a suitable tmpfs in /run.

So maybe that logic.

---

Also in the Docker Container, PID 1 shows /run/service as the path for s6-svscan.
Maybe you could query ps -fp 1 for that.

@ChuckPa I just wanted to let you know that the current script works with Unraid version 6.12.13 and Linuxserver/docker-plex version 1.41.0.8992-8463ad060-ls235.

I downloaded the script via cli directly into the container:

docker exec -it plex /bin sh

apt-get update

apt-get install git -y

##A few moments later....###

git clone https://github.com/ChuckPa/PlexDBRepair.git

cd "/config/Library/PlexDBRepair"

Then launched the script via "./PlexDBRepair.sh"

Able to select option #1 to stop PMS

Then run / select any other option of my choice including #2 which runs smoothly just takes time because in my instance "com.plexapp.plugins.library.blobs.db" = 975MB & "com.plexapp.plugins.library.db" = 1.08GB in size.

Once again, I thank you @ChuckPa and your team for all of your hard work behind the scenes.

If you all want any further info or detail please let me know here or via PM.

[ChuckPa]

Well isn't this problematic 😄

For the life of me, I cannot figure out why these lines, which have worked for a long time now, suddenly fail.

      # Miscellaneous start/stop methods
      if [ -d "/var/run/service/svc-plex" ]; then
        HaveStartStop=1
        StartCommand="s6-svc -u /var/run/service/svc-plex"
        StopCommand="s6-svc -d /var/run/service/svc-plex"
      fi

      if [ -d "/run/service/svc-plex" ]; then
        HaveStartStop=1
        StartCommand="s6-svc -u /run/service/svc-plex"
        StopCommand="s6-svc -d /run/service/svc-plex"
      fi

      if [ -d "/var/run/s6/services/plex" ]; then
        HaveStartStop=1
        StartCommand="s6-svc -u /var/run/s6/services/plex"
        StopCommand="s6-svc -d /var/run/s6/services/plex"
      fi

I'm not testing for writeable.
This test shows shows directories are seen through the link.

[chuck@lizum ~.2000]$ mkdir /tmp/a
[chuck@lizum ~.2001]$ ln -s /tmp/a a
[chuck@lizum ~.2002]$ [ -d a ] && echo directory
directory
[chuck@lizum ~.2003]$ ls -la a

I'm glad it helped.
There are a couple here which help me with this monster I've created. ( I had no idea it would be like this when started) lol

I've figured out how to do multiple-level 'undo' commands .
This would allow you to do anything you want then unwind all the way back to the beginning.

It sounds like fun but feels like superfluous fluff.

I use this in all my production and testing work at Plex (I use a lot of LXCs)
I'm glad it's out there to help the thousands who've used it so far

I get it. Its been a task for sure but much appreciated. I have used the script on both Synology & Unraid which have both come as life savers thank to the help of yourself and your team. @ChuckPa
