#
# DESCRIPTION:
# Ensure that checkpoint plays well with indirect mappings
# and blocks.
#
# STRATEGY:
# 1. Import pool that's slightly fragmented
# 2. Introduce indirection by removing and re-adding devices
# 3. Take checkpoint
# 4. Apply a destructive action and do more random writes
# 5. Run zdb on both current and checkpointed data and make
# sure that zdb returns with no errors
#

# Display fragmentation after removals

#
# Destroy one dataset, modify an existing one and create a
# a new one. Do more random writes in an attempt to raise
# more fragmentation. Then verify both current and checkpointed
# states.
