Title:
v1 API: image data downloads for images in pending_delete fails
Status in OpenStack Image Registry and Delivery Service (Glance):
In Progress
Status in OpenStack Compute (Nova):
Opinion
Bug description:
Use case: user spawns an instance, then deletes the boot image, to
prevent new instances from being spawned with it. Later, the user
wants to live migrate the instance to a new hypervisor.
As part of this, nova will attempt to download all the images used by
the instance on the target node to populate its image cache. Because
the image used is no longer in an explicit "active" state, the Glance
v1 API returns a 404 Not Found.
According to the docs, pending_delete is supposed to be recoverable,
which could arguably imply that downloading and re-uploading the image
would be allowed; so this smells like a bug.
I will not let the fact that Mark just told me in as many words that
it is not dissuade me from this point of view. ;-)
