# DESCRIPTION:
# Scrubbing a pool with offline devices correctly preserves DTL entries
#
# STRATEGY:
# 1. Create the pool
# 2. Offline the first device
# 3. Write to the pool
# 4. Scrub the pool
# 5. Online the first device and offline the second device
# 6. Scrub the pool again
# 7. Verify data integrity
#
# NOTE:
# Ported from script used to reproduce issue #5806
