OpenStack maas/juju on NUCs with one drive each

I set up my mass and juju, and commissioned four NUC's. I attempted the juju charm to deploy the bundle, but it seems it MUST have three drives on each metal node? NUC's seem to only have capacity for one drive, older models that I planned to use for a POC deployment. These all have 4 cores and 8 gig RAM and a 1T drive. Is there a way around this? Perhaps this as more of a juju/canonical question?

This charm requires two disks, one for the OS, the other for Ceph. If you replace Ceph by Swift, you might need more. Which charm are you trying?

DISCLAIMER: I know practically nothing about deployment with MAAS and Juju.

Perhaps it's possible to simulate disks with loop devices.

I am new to the entire stack, so wanted to try a proof of concept following: https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/install-maas.html (https://docs.openstack.org/project-de...)

Unsure if there are better or different charms, totally new to juju.

I might be wrong, but the document that you refer to doesn't say you have to have 3 disks. Rather, as an example, it shows how MAAS discovers nodes that have three disks each.

The Ceph charm must be configured with a YAML that specifies a second drive, it will wipe it it seems, must be clean. Then the Swift charm requires a third. Maybe those are not required for OpenStack. If OpenStack doesnt req, maybe there is a better charm?
