  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.
