# Shrink the VM Disk File on Proxmox

## 1. Get Volume ID

$ pvesm list local-lvm --vmid 534
Volid                      Format  Type              Size VMID
local-lvm:vm-534-cloudinit raw     images         4194304 534
local-lvm:vm-534-disk-0    raw     images    107374182400 534

## 2. Get the path to the disk

$ pvesm path local-lvm:vm-534-disk-0
/dev/pve/vm-534-disk-0

## 3. Shrink the Disk File

$ qemu-img convert -p -f raw -O qcow2 /dev/pve/vm-534-disk-0 /root/ub2204/ub2204.qcow2
    (100.00/100%)

## 4. Check

$ ls -lh ub2204/
total 12G
-rw-r--r-- 1 root root  12G May 19 13:14 ub2204.qcow2
