30# DESCRIPTION:
31# After initializing, the disk is actually initialized.
32#
33# STRATEGY:
34# 1. Create a one-disk pool.
35# 2. Initialize the disk to completion.
36# 3. Load all metaslabs that don't have a spacemap, and make sure the entire
37#    metaslab has been filled with the initializing pattern (deadbeef).
