# DESCRIPTION:
#	'zpool replace' should use the ashift pool property value as default.
#
# STRATEGY:
#	1. Create a pool with default values.
#	2. Verify 'zpool replace' uses the ashift pool property value when
#	   replacing an existing device.
#	3. Verify the default ashift value can still be overridden by manually
#	   specifying '-o ashift=<n>' from the command line.
