Openstack storage

Hello everyone! I am trying to install Openstack Base on my lab of 3 HP G8 with 4 disks. 2x300 in raid1 /dev/sda for OS installation and 2x600 /dev/sdb, /dev/sdc for Openstack storage. Before deploy I only change “osd-devices:” in openstack-base/bundle.yaml osd-devices: &osd-devices /dev/sdb /dev/sdc

After reinstallation (due to radosgw issue) in juju status everything is green and active. But in Openstack horizon, only system disks are displayed in local storage. 2021-10-05 12_46_27-Hypervisors - OpenStack Dashboard

You’ve included juju status output but minus the relations. Can you provide output to juju status --relations?

Tracking the code with the traceback, it appears that the RBD image name is missing, probably at some point in the configuration. Could you paste the contents of the file /etc/cinder/cinder.conf from the machine that is running the cinder charm ?
