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