33 +The actual disk is mounted as a mapper device. If is was LXC container with id 401, a disk might look like `/dev/mapper/pve-vm--401--disk--0`
34 +
35 +```bash

52 +Identify the vm disk path using the command:
53 +
54 +```bash
55 +pvesm path STORAGE:vm-VM_ID-disk-0
56 +```
57 +
58 +Stop the container or vm:
59 +
60 +```bash
61 +qm stop 401
62 +or
63 +lxc-stop 401
64 +```
65 +
66 +Then convert the the storage with:
67 +
68 +```bash
69 +qemu-img convert -p -O qcow2 $(pvesm path local-lvm:vm-401-disk-0) vm-401-disk-0.qcow2
70 +```
71 +
72 +note, here we also move the storage from `local-lvm` to `nvme`.
