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 ..

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.
