33# DESCRIPTION:
34# Scrubbing a pool with offline devices correctly preserves DTL entries
35#
36# STRATEGY:
37# 1. Create the pool
38# 2. Offline the first device
39# 3. Write to the pool
40# 4. Scrub the pool
41# 5. Online the first device and offline the second device
42# 6. Scrub the pool again
43# 7. Verify data integrity
44#
45# NOTE:
46# Ported from script used to reproduce issue #5806
