Public bug reported: Copying of larger images using copy-image import method fails for AWS S3 store. The reason is while copying the image it uses 'single_part' upload for uploading large images. On normal image creation process it does uses 'multi_part' upload and thus works fine.
After further analyzing the code in glance, image size is not passed to [1] which is required to decide the upload mechanism on S3 side. [1] https://github.com/openstack/glance_store/blob/master/glance_store/_drivers/s3.py#L628 Possible solution: Since we have image size available at the time of copying the image, we should pass it all the way to s3 driver through onion layer of glance. ** Affects: glance Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
