# DESCRIPTION:
# Starting, stopping, uninitializing, and restart an initialize works.
#
# STRATEGY:
# 1. Create a one-disk pool.
# 2. Verify uninitialize succeeds for uninitialized pool.
# 3. Verify pool wide cancel|suspend + uninit
#   a. Start initializing and verify that initializing is active.
#   b. Verify uninitialize fails when actively initializing.
#   c. Cancel or suspend initializing and verify that initializing is not active.
#   d. Verify uninitialize succeeds after being cancelled.
# 4. Verify per-disk cancel|suspend + uninit
#
