That original volume is still taking up disk space, so absolutely needs to be part of the quota and billing. We talked about allowing snapshots to exist when their origin volume is deleted in cinder (I was an advocate of it), but it turns out to be impossible on some backends without lots of data copying, and having a quota system that does not represent the actual resource usage is begging for s DoS attack. _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
