# DESCRIPTION:
# 'zfs create -s -V <size> <volume>' can create various-size sparse volume.
#
# STRATEGY:
# 1. Create a volume in the storage pool.
# 2. Verify the volume is created correctly.
# 3. Verify that the volume created has its volsize rounded to the nearest
#    multiple of the blocksize (in this case, the default blocksize)
#
