TR-3742(http://media.netapp.com/documents/tr-3742.pdf) states:
2.6 CREATING A FLEXCLONE INSTANCE OF A FILE IN A SAN ENVIRONMENT
...
Host-side tool support is needed to integrate the cloned data blocks into the host file system and to present the cloned file to the host file system.
Though TR-3742 is dated 2010 I can't find any trace of real-world implementation of file FlexClone. What I need is the way to clone VHD files on a CSV LUN used in Hyper-V virtualization cluster.
Is file FlexClone really implemented, or does the feature exist only on paper? If it really exists, how can I use it (preferably from a PS script)? If it is a waporware, are there any plans to implement it in the real world?
