He can't do it that way because the Falconstor is a raw block device and has no idea the difference between a snapshot and other filesystem bits. Robert - we have some very alpha patches in house that allow suspension of UFS filesystems for things like this (also working on online UFS growing). I'm not sure how close we really are to letting it loose in the wild, but we will definitely be making all the patches available to whomever wants it.
