# DESCRIPTION:
#	For raidz2, two destroyed pool's devices were removed or used by other
#	pool, it still can be imported correctly.
#
# STRATEGY:
#	1. Create a raidz2 pool A with N disks.
#	2. Destroy this pool A.
#	3. Create another pool B with two disks which were used by pool A.
#	4. Verify import this raidz2 pool can succeed.
