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
