# How to mount LVM image
You want to read your LVM image (ex: you did some errors and can't start the VM ).
1: make the image available for qubesdb.
```bash
# Example: /dev/qubes_dom0/vm-debian-9-tmp-root
[user@dom0]$ dev=$(basename $(readlink /dev/YOUR_LVM_VG/YOUR_LVM_IMAGE))
[user@dom0]$ qubesdb-write /qubes-block-devices/$dev/desc "YOUR_LVM_IMAGE"
```
2: Create a new disposable VM
```bash
[user@dom0]$ qvm-run -v --dispvm=YOUR_DVM_TEMPLATE --service qubes.StartApp+xterm &
```
3: Attach the device to your newly created disp VM
From the GUI, or from the command line:
```bash
[user@dom0]$ qvm-block attach NEWLY_CREATED_DISPVM dom0:$dev
```
4: Mount the partition you want to, and do what you want with it
```bash
[user@dispXXXX]$ mount /dev/xvdiX /mnt/
```
5: Umount and kill the VM
```
[user@dispXXXX]$ umount /mnt/
```
6: Remove the image from qubesdb
```
[user@dom0]$ qubesdb-rm /qubes-block-devices/$dev/
```
