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