Provide a (semi) official way to increase Cinder Loop Device Size after initialization + changing it's location

[Lucca Jiménez Könings]

Hello,

I am currently unable to open a topic on the Microstack Discourse, so I'll just ask my question here:

Can we get a (semi) official guide on how to resize the Cinder loop-device backend after microstack initialization? Currently, a working solution has been reported here:

https://discourse.charmhub.io/t/microstack-cannot-create-volumes/4518

I understand that Microstack is currently in beta, but I'd just like some confirmation if this is a "valid" way of extending the volume after init.

Additionally, If I wanted to change the location of the file,
is that possible without much effort? How can this be done?
