40# DESCRIPTION:
41#	zpool history can record and output huge log.
42#
43# STRATEGY:
44#	1. Create two 100M virtual disk files.
45#	2. Create test pool using the two virtual files.
46#	3. Loop N times to set compression to test pool.
47#	4. Make sure 'zpool history' output correctly.
48#
49# TESTABILITY: explicit
50#
51# TEST_AUTOMATION_LEVEL: automated
52#
53# CODING_STATUS: COMPLETED (2006-07-05)
