  35 # DESCRIPTION:
  36 #       zpool history will truncate on small pools, leaving pool creation intact
  37 #
  38 # STRATEGY:
  39 #       1. Create two 100M virtual disk files.
  40 #       2. Create test pool using the two virtual files.
  41 #       3. Loop 100 times to set and remove compression to test dataset.
  42 #       4. Make sure 'zpool history' output is truncated
  43 #       5. Verify that the initial pool creation is preserved.
