I am 100% sure Netapp Flexclone can change the ownership of the clone content.
We are using that functionality right now.


When you create clone in Flrxclone, you can specify a uid/gid. 
When the clone is created, all the files/directories/content in that clone is 
instantly owned by the uid/gid.

What I have been looking for is a similar functionality in Btrfs or ZFS?

I would like to put a diskimage on NFS, and mount it as a disk on my machine. 
And I want such snapshot and cloning(change ownership) capabilities in that 
disk image.

So I was considering BTRFS or ZFS, and was wondering if they miht have that

    You are probably mistaken. NetApp FlexClone (which you probably mean)
    does not have any ways to change volume content. Of course you can now
    mount this clone and do whatever you like from host, but that is
    completely unrelated to NetApp itself and can just as well be done using
    btrfs subvolume.
