#
# DESCRIPTION:
# Rewind to checkpoint on a stressed pool. We basically try to
# fragment the pool before and after taking a checkpoint and
# see if zdb finds any checksum or other errors that imply that
# blocks from the checkpoint have been reused.
#
# STRATEGY:
# 1. Import pool that's slightly fragmented
# 2. Take checkpoint
# 3. Apply a destructive action and do more random writes
# 4. Run zdb on both current and checkpointed data and make
# sure that zdb returns with no errors
# 5. Rewind to checkpoint
# 6. Run zdb again

# 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.
