Dear colleagues, for some reasons, I need to shrink image size to zero (freeing storage as well), while keeping this record in Glance database. First which come to my mind is to delete image and then create new one with same name/uuid/... and --file /dev/null, but this is impossible because Glance don't really delete records from database, marking them as 'deleted' instead. Next try was to use glance image-upload from /dev/null, but this is also prohibited with message "409 Conflict: Image status transition from [activated, deactivated] to saving is not allowed (HTTP 409)" I found https://docs.openstack.org/glance/rocky/contributor/database_architecture.html#glance-database-public-api's "image_destroy" but have no clues on how to access this API. Is it kind of library or kind of REST API, how to access it and whether it's safe to use it in terms of longevity and compatibility between versions? Or, may be, you can advise any other methods to solve the problem of zeroing glance image data / freeing storage, while keeping in database just a record about this image? Thank you. -- Volodymyr Litovka "Vision without Execution is Hallucination." -- Thomas Edison
