36# DESCRIPTION:
37# 'zpool add -n <pool> <vdev> ...' can display the configuration without adding
38# the specified devices to given pool
39#
40# STRATEGY:
41# 1. Create a storage pool
42# 2. Use -n to add devices to the pool
43# 3. Verify the devices are not added actually
44# 4. Add devices to the pool for real this time, verify the vdev tree is the
45#    same printed by the dryrun iteration
