# STRATEGY:
# 1. Create a one-disk pool.
# 2. Initialize the disk to completion.
# 3. Load all metaslabs that don't have a spacemap, and make sure the entire
# metaslab has been filled with the initializing pattern (deadbeef).
# 3. Load all metaslabs and make sure that each contains at least
# once instance of the initializing pattern (deadbeef).
