Openstack volume deletion

Hi, OpenStack Kolla Ansible has been installed on Ubuntu 20 and integrated with Ceph storage. The volume associated with the instance is not being deleted by Cinder when I terminate the instance with this option (Delete Volume on Instance Delete), which is causing me problems. I need to log in to the server and run the cinder commands to manually delete the volume that is not associated with instances. I would appreciate it if you could provide a solution. Thanks, Vijay
