max "raw" datasize and solutions

[SeWizarD]

So, a problem I realized:

LXC, mount and rootdisk sizes, are seemable limited to about 2TB.

- error if bigger: TASK ERROR: command '/usr/bin/qemu-img resize -f raw /home/images/100/vm-100-disk-0.raw 2200000000000' failed: exit code 1
(".raw datasize limited")

Soo, I actually need my drive(one drive) to be bigger than that solutions I thought about:
- creating 2TB mountpoint and somehow fuse them (don't know how)
- change the data type?

Hope you know some solutions to this, running out of ideas I can find a solution to (actually never had solutions I found something, haha ^^)

Thanks for reading. I am looking forward to hearing your ideas and solutions !!

Already found a solution
Creating multiple mounting points and fusing them to one directory:

refering to: https://serverfault.com/questions/191299/can-we-mount-multiple-disks-as-one-directory

Containers run best with ZFS and you will not have any of the limitations.

PSS: if you already have a hdd or ssd bigger than the "limit" use a shared folder aka bind mount point

go to:
/etc/pve/lxc/[LXC-ID].conf

edit with additional line:
mp0: /mnt/bindmounts/shared(source),mp=/shared(destination)
