Regarding juju Storage - using MAAS as cloud provider

There are some documentation about creating storage on MAAS here:

Using this document you should be able to create block devices in MAAS that
you can later use in Juju.

The Juju storage documentation can be found here:

As an example, once you have your MAAS storage created and tagged, you
could create a storage pool in Juju like this:

juju create-storage-pool mypool maas tags=<maas-tag>

And then you could add a storage constraint to deploy your charm like this:

juju deploy <charm> --storage disks=mypool,1G

I have not tried MAAS storage with Juju so you may need some additional
commands. If anyone else has examples of combining MAAS storage with Juju
please reply here to let us know. Thanks!
