I am planning on using a centralized storage array with my Openstack deployment. I’ve done the deployment on the past and configured the cinder.conf files by hand, so I know what I need to place on that file and also the .deb file I need to install on every storage node. I want to know if you guys can guide me as to how should I proceed to do the same thing on juju because now I’m deploying a charmed Openstack. Do I need to write a charm configure the cinder.conf file and put there my storage backend configuration? If so, Do you know where I could start looking for information? I have deployed an Openstack cloud with CEPH using other’s charms but never created my own. I also went through the charm store and didn’t find one for my storage vendor.
