The Copy offload binary is a special RPC implemented in Ontap that allows NFS clients to ask the server to copy data between volumes in the same cluster efficiently. The special binary will be developed by NetApp and distributed to its customers. It will address two copy cases after efficient image clone failed. First when image cache file is present in a different share than the one holding volume. Second when glance is backed by nfs share which is on the same cluster as nfs driver backend. Instead of regular http download the copy offload workflow will be used to copy image to share and volume. Resubmitting it as there was a problem with build in previous submission.
