[Bug 1785800] Re: Not possible to delete volume which was attached
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:

Steps to reproduce
==================
1. 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.
Actual result
=============
1. Fails to delete the Volume.
logs show:

This may have been caused by a connection from a client that has crashed and, if so, may be resolved by retrying the delete after 30 second
