if it is easier, I do know about tmmate and could use that. If that helps you help me that is 
At the moment, Iām a bit backed up but can probably make some time to help you later today if thatās ok.
My friend, who is so much better at this than I, has isolated an issue. Plex, it seems, is running in docker.
This is my cautionary tale. I tried to use pgblitz/plexguiide.
It didnāt do what I wanted it to. It did things, but⦠beyond my scope.
and apparently put every single thing it installed into docker.
So, no matter how many times I install/reinstall, docker is there⦠waiting.
So thatās it for now, a further update once I figure out how badly I have ruined my system and need to format/wipe.

Thank you all again for the help, truly!
Lol, that would have been a valuable piece of informationā¦
Hey, you think YOU would have liked to know? Iāve spent a whole 24 hours on thisā¦
WHY CANT IT BE MORE GUI?!?
sorry, thatās a linux rant. apologies.
(editing as my replies are maxed)
Itās not that I hate it- itās that I am learning it and it is new and I am old.
also, linux is a beast when things go like they should.
Iām on an AMD A-10 for crying out loud! When I was using windows on this box, it took 20 minutes to boot!
Just sayin, I like linux, always have, even when I played with freebsd or whatever that was. But itās frustrating when something like docker here can just ⦠hijack⦠things. But enough about that. Weāre knee deep into trying to conf this to work and the exfat may be an issue.
The solution via my friend
What I did was I went into PlexGuide settings. The multi-drive paths were set to the devices instead of the mounts, so I changed that to the mounts after that ran the deploy thing twice
Solved! They now show under /mnt/union.
Thank you all again for the help!
Why are you using Linux if you hate it so much? 
Docker does not hijack anything, you just have not understood how it works obviously 
You have to mount the directory you want to use to the docker container, it just does not get access to the file system by default, but only the folders you allow it to see.
Hijacking the solution.
Iām said friend.
PG installs everything into Docker containers where Plex sees the directory /mnt/ as /mnt/ on the host system
As the disks were in /disks/ it would be impossible for the Plex docker container to see the drives.
There are two possible solutions:
- Move the mountpoints on the host system to somewhere under /mnt/
- Do it the proper way, and use PGās UnionFS system to mount /disks/b and /disks/c to /mnt/unionfs
We went with the second option. It turned out that multi-disk unionfs was already configured however the paths were set to /dev/sdb2 and /dev/sdc2. To fix it the paths were updated to /disks/c and /disks/b which ultimately solved the problem.
Unionfs is something that is not necessary on a local machine I would say, I use this on my vps to combine local and cloud storage.
In this case this would introduce an additional layer without my benefit.
Edit: ok maybe I didnāt get the reason for the unionfs. You probably know it better then me
