# DESCRIPTION:
#	The largest pool can be created and a dataset in that
#	pool can be created and mounted.
#
# STRATEGY:
#	create a pool which will contain a volume device.
#	create a volume device of desired sizes.
#	create the largest pool allowed using the volume vdev.
#	create and mount a dataset in the largest pool.
#	create some files in the zfs file system.
#	do some zpool list commands and parse the output.
