All;
The overall issue has been resolved.
There were two major causes:
Misplacement of keyring(s) (they were not within /etc/ceph/)
'openstack-cinder-volume' service was not started/enabled

Subject: [ceph-users] [cinder] Cinder & Ceph Integration Error: No Valid Backend
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

cinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;volume:create: No valid
backend was found. No weighed backends available: cinder.exception.NoValidBackend: No
valid backend was found. No weighed backends available
Here is the 'cinder.conf' from our Controller Node:

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