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