The COW file is allocated by filling it with zeroes. This is the result of epic #219, which was needed for the direct IO to ensure the COW file is completely initialized from the FS perspective. Still, this seems a time-consuming operation on large volumes (it may take up to a couple of minutes) which can be improved. The appropriate investigation is required to find the best solution.
