Sometimes this happens out of the blue, and I end up having to reinstall QubesOS. Could you please tell me how to resolve this issue?
The error “Logical volume vm-sys-net-volatile already exists in volume group qubes_dom0” typically occurs in Qubes OS after an unclean shutdown or crash, where temporary (volatile) logical volumes were not properly cleaned up. These volumes are meant to be ephemeral and can usually be safely removed to resolve the issue.
-
Open a terminal in dom0.
-
First, check for the existence of the conflicting logical volume:
lvdisplay | grep vm-sys-net-volatile
or list all logical volumes to confirm:
sudo lvs
- If the volume is found (e.g.,
/dev/qubes_dom0/vm-sys-net-volatile), remove it with:
sudo lvremove /dev/qubes_dom0/vm-sys-net-volatile
-
Confirm the removal when prompted.
-
Reboot or attempt to start the affected VM (e.g.,
sys-net) via Qubes Manager or command line:
qvm-start sys-net
This should resolve the conflict, as volatile volumes do not contain persistent data and are recreated on demand.
