(Get the code!)
The NetApp zapi for clone create has an undocumented limit of 32 block ranges (of a max 2^32 blocks each).
The driver should check to make sure the number of block range segments does not exceed 32. In the case of an excessively large request, the xml may be rejected by the filer silently and the volume will become stuck in an extending state, with 2 flexVols (the original and the new sized one) present on the filer.
