Openstack Component not working

Hi All, I am new to openstack and it's deployment, so having some issues with it.

I deployed openstack bundle using juju(version 2.6.9-bionic-amd64) and this tutorial https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/install-openstack-bundle.html.

After deployment I found out ceph-osd and ceph-radosgw has status "blocked" and message "No block devices detected using current configuration". Can you please shed light on what the problem maybe. Also some other components such as "nova-compute" complains of "Incomplete relations: storage-backend". What do I need to do to rectify this. I have tried to instal openstack by components, but this does not resolve it.

I cannot upload pictures because I am a new member, but below shows what I see, when I run juju status
