The NetApp driver uses NetApp specific API calls to implement the actual
cloning of the file. You could probably generalize it by implementing the
keeping of a cached image file on the destination share for future copies,
and then implement a standard copy file method that could be overloaded

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):

It looks quite an interesting and
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
