Nice idea.

Actually, fast image cloning has been widely supported by most NAS devices, and VMware VAAI also started to require this criteria many years ago.

However, I am not quite sure what exactly need to put into the base NFS driver, anyways, the fast cloning api will vary for specific vendors.

Subject: [openstack-dev] Efficient image cloning implementation in NetApp nfs drivers // make this part of base NFS driver

Hi All,

I was going through the following blue print, NetApp proposed and implemented in its driver (NetAppNFSDriver - cinder/volume/drivers/netapp/nfs.py ) a while back (change<https://review.openstack.org/#/c/41868/>):
https://blueprints.launchpad.net/cinder/+spec/netapp-cinder-nfs-image-cloning

It looks quite an interesting and valuable feature for the end customers.
Can we make it part of the base NfsDriver (cinder/volume/drivers/nfs.py)? so that the customers using the base NFS driver can benefit and also other drivers inheriting from this base NFS driver (e.g. IBMNAS_NFSDriver, NexentaNfsDriver) can also benefit.

Please let me know your valuable opinion.
I can start a blueprint for the Juno release.

Thanks,
Nilesh
