28# DESCRIPTION:
29#	Verify that cloning a file at a large offset is possible.
30#
31# STRATEGY:
32#   1. Create dataset.
33#   2. Populate the source file with 1024 blocks at 1024 block offset.
34#   3. Clone 1024 blocks at a 1024-block offset.
35#   4. Compare the cloned file with the original file.
