32# DESCRIPTION:
33#	'zpool replace' should use the ashift pool property value as default.
34#
35# STRATEGY:
36#	1. Create a pool with default values.
37#	2. Verify 'zpool replace' uses the ashift pool property value when
38#	   replacing an existing device.
39#	3. Verify the default ashift value can still be overridden by manually
40#	   specifying '-o ashift=<n>' from the command line.
