# DESCRIPTION:
# zpool history will truncate on small pools, leaving pool creation intact
#
# STRATEGY:
# 1. Create a test pool on a file.
# 2. Loop 300 times to set and remove compression to test dataset.
# 3. Make sure 'zpool history' output is truncated
# 4. Verify that the initial pool creation is preserved.
