How to mount LVM images
|
||
=======================
|
||
|
||
|
||
You want to read your LVM image (e.g., there is a problem where you can’t start any VMs except dom0).
|
||
|
||
1: make the image available for qubesdb. From dom0 terminal:
|
||
|
||
.. code:: 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/$dev/desc "YOUR_LVM_IMAGE"
|
||
|
||
|
||
2: Create a new disposable VM
|
||
|
||
.. code:: bash
|
||
|
||
[user@dom0]$ 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:
|
||
|
||
.. code:: bash
|
||
|
||
[user@dom0]$ qvm-block attach NEWLY_CREATED_DISPVM dom0:$dev
|
||
|
||
|
||
4: Mount the partition you want to, and do what you want with it
|
||
|
||
.. code:: bash
|
||
|
||
[user@dispXXXX]$ mount /dev/xvdiX /mnt/
|
||
|
||
|
||
5: Umount and kill the VM
|
||
|
||
.. code:: bash
|
||
|
||
[user@dispXXXX]$ umount /mnt/
|
||
|
||
|
||
6: Remove the image from qubesdb
|
||
|
||
.. code:: bash
|
||
|
||
[user@dom0]$ qubesdb-rm /qubes-block-devices/$dev/
