All;
We're having problems with our Openstack/Ceph integration. The versions we're using are Ussuri & Nautilus.
When trying to create a volume, the volume is created, though the status is stuck at 'ERROR'.
This appears to be the most relevant line from the Cinder scheduler.log:
2021-01-07 14:00:38.473 140686 ERROR cinder.scheduler.flows.create_volume [req-f86556b5-cb2e-4b2d-b556-ed07e632289d 824c26c133b34d8b8e84a7acabbe6f91 a983323b5ffc47e18660794cd9344869 - default default] Failed to run task cinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;volume:create: No valid backend was found.

Here is the 'cinder.conf' from our Controller Node:

Does anyone have any ideas as to what is going wrong?
