19# Description:
20# Verify that ZAPs are handled properly during mirror pool splitting.
21#
22# Strategy:
23# 1. Create a pool with a two-way mirror.
24# 2. Split the pool.
25# 3. Verify that the ZAPs in the old pool persisted.
26# 4. Import the new pool.
27# 5. Verify that the ZAPs in the new pool persisted.
