"qemu-img: Cannot resize device files" when trying to shrink vm disk

[kakao73]

I tried below:

$ qemu-img resize -f raw --shrink $(pvesm path <lvm-thin-storage>:<vm-disk>) -1G
qemu-img: Cannot resize device files

How can I shrink it?

AFAIK, qemu-img doesn't handle LVM(-thin). You will need to use the lvreduce command directly.

@Alwin Ah, thanks.
