Proxmox how to shrink mounted lvm lxc?

Question

LXC

There is proxmox 6.1, it has an lxc container with ubuntu 18.04. The root partition with lvm is connected to ubuntu.
We need to reduce its size. It is clear how to reduce it by turning off the container.

lvresize --size -4G --resizefs /dev/vg0/vm-100-disk-0

But it is required to do this without shutting down the container. Is it possible to do this and what are the ways. Haven't been able to find any info on google yet.

Answer 1

No, you have to turn it off.
