# DESCRIPTION:
#	Verify set, export and destroy when cachefile is set on pool.
#
# STRATEGY:
#	1. Create two pools with one same cahcefile1.
#	2. Set cachefile of the two pools to another same cachefile2.
#	3. Verify cachefile1 not exist.
#	4. Export the two pools.
#	5. Verify cachefile2 not exist.
#	6. Import the two pools and set cachefile to cachefile2.
#	7. Destroy the two pools.
#	8. Verify cachefile2 not exist.
