As I see it, the process would look something like this:- Nova detaches volume using OS-Brick - Nova calls Cinder re-image passing the node's info (like we do when attaching a new volume) - Cinder would: - Ensure only that node is connected to the volume - Terminate connection to the original volume - If we can do optimized volume creation: - If encrypted volume we create a copy of the encryption key on Barbican or copy the ID field from the DB and ensure we don't delete the Barbican key on the delete. - Create new volume from image - Swap DB fields to preserve the UUID - Delete original volume - If it cannot do optimized volume creation: - Initialize+Attach volume to Cinder node - DD the new image into the volume - Detach+Terminate volume - Initialize connection for the new volume to the Nova node - Return connection information to the volume - Nova attaches volume with OS-Brick using returned connection information. So I agree, it's not a blockRebase operation, just a change in the volume that is used.
Yeah we're on the same page with respect to the high level changes on the nova side.
