35# DESCRIPTION:
36#	zpool history can record and output huge log.
37#
38# STRATEGY:
39#	1. Create two 100M virtual disk files.
40#	2. Create test pool using the two virtual files.
41#	3. Loop N times to set compression to test pool.
42#	4. Make sure 'zpool history' output correctly.
43#
44# TESTABILITY: explicit
45#
46# TEST_AUTOMATION_LEVEL: automated
47#
48# CODING_STATUS: COMPLETED (2006-07-05)
