31# DESCRIPTION:
32#	'zpool add' works with nested replacing/spare vdevs
33#
34# STRATEGY:
35#	1. Create a redundant pool with a spare device
36#	2. Manually fault a device, wait for the hot-spare and then replace it:
37#	   this creates a situation where replacing and spare vdevs are nested.
38#	3. Verify 'zpool add' is able to add new devices to the pool.
