Trickplays plays tricks on my storage

[Squid]

Ok- so i use this LXC script to install a jellyfin LXC container. so far so good.

How every yesterday, i learned the hard way that filling container space corrupts system.xml and i did a reinstall today.
I selected for library to create trickplay "next to media" and let it run for a while. 

How ever i see / grow. I have a seperate folder mounted to /media/ and library of movies and series are in a subfolder of this path, but if i go look around fold a folder called trickplay, i cannot find one.

Filesystem            Size  Used Avail Use% Mounted on
VM/subvol-101-disk-0  32G  8.0G  25G  25% /
data/Media            46T  31T  15T  68% /media

Im trying to get the large extra stuff into /media somewhere, and not fill the container subvolume up. If i go generate trickplay (schedule) it seems to grow the subvol and not /meta

But on the subvol i cannot find any folder called trickplay 

Code:

find . -name trickplay -type d

In the LXC, jellyfin does not run in docker.


EDIT:

Now an hour later or something, still growing on the wrong place

Filesystem            Size  Used Avail Use% Mounted on
VM/subvol-101-disk-0  32G  15G  18G  44% /
data/Media            46T  31T  15T  68% /media

I would check to see if the Jellyfin service user has write access to the media location.

I would check to see if the Jellyfin service user has write access to the media location.

It does: 

drwxrws--T  9 jellyfin jellyfin    9 Mar  3 12:06 media


drwxrws--T  9 jellyfin jellyfin  9 Mar  3 12:06 .
drwxr-x---  6 jellyfin jellyfin  9 Feb 28 16:27 ..
drwxr-sr-x  4 jellyfin jellyfin  5 Mar  3 12:11 laptop
drwxrwsr-x  5 jellyfin jellyfin  5 Mar  3 00:14 media

I would also redo the mount point for "VM/subvol-101-disk-0".
I don't have much experience with LXC, so I'm not sure or aware of a reason to use "/" as a mount point.

It being "/" while media mount is "/media" is probably causing this issue.

Try giving it a different mount point name.

Can you share your full jellyfin log via privatebin.net? To confirm what trickplay is doing. IIRC, it will write to the log that it doesn't have permission to write to your media directory before falling back to writing to the Jellyfin appdir.
