32# DESCRIPTION:
33#	'zpool add -o ashift=<n> ...' should work with different ashift
34#	values.
35#
36# STRATEGY:
37#	1. Create a pool with default values.
38#	2. Verify 'zpool add -o ashift=<n>' works with allowed values (9-16).
39#	3. Verify setting kernel tunable for file vdevs works correctly.
40#	4. Verify 'zpool add -o ashift=<n>' doesn't accept other invalid values.
