failed to start microstack lvm service

[Robert Gildein]

Failed to start microstack.setup-lvm-loopdev.service after stopping all microstack
services using the snap. More details and how they can be reproduced can be found here [1].

The microstack.setup-lvm-loopdev failed with error 'Volume group "cinder-volumes" not found'.

```bash

I was able to fix this by running `sudo microstack init --auto --control` again.

Tried to fix this by running `sudo microstack init --auto --control` but did not work.

Any suggestions?
Thanks,
