This isn't really a valid workflow. You need to first detach the volume from the server via the compute API:
https://docs.openstack.org/python-openstackclient/latest/cli/command- objects/server.html#server-remove-volume And then you can delete the volume. The volume attachments API in Cinder is really meant for nova/cinder internal communication, not really for end users. Think of it like the neutron port binding API extension which is admin-only by default. The difference is until I think Queens, nova didn't have configuration options to have admin/service credentials for cinder. That is possible now, but it's not yet required so Cinder can't just change the policy rules on the attachments API without breaking some backward compatibility. See: https://docs.openstack.org/cinder/latest/configuration/block- storage/policy.html volume:attachment_create Default: <empty string> Operations: POST /attachments Create attachment. volume:attachment_update Default: rule:admin_or_owner Operations: PUT /attachments/{attachment_id} Update attachment. volume:attachment_delete Default: rule:admin_or_owner Operations: DELETE /attachments/{attachment_id} Delete attachment. volume:attachment_complete Default: rule:admin_or_owner Operations: POST /attachments/{attachment_id}/action (os-complete) Mark a volume attachment process as completed (in-use) And: https://docs.openstack.org/nova/latest/configuration/config.html#cinder ** Changed in: nova Status: New => Invalid -- You received this bug notification because you are a member of Yahoo!

Create volume. 2. Create VM. 3. Attach the VM to the volume - volume status - "in-use". 4. Delete the attachment using cinder - cinder --os-volume-api-version 3.27 attachment-delete <attachment-id >. 5. Check that the volume status is - "available". 6. Delete the volume. - See that the volume not deleted and remain in "available" status. Expected result =============== 1. Volume will be deleted after the attachment delete using cinder.
