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