# DESCRIPTION:
# Test /proc/spl/kstat/zfs/<pool>/state kstat
#
# STRATEGY:
# 1. Create a mirrored pool
# 2. Check that pool is ONLINE
# 3. Fault one disk
# 4. Check that pool is DEGRADED
# 5. Create a new pool with a single scsi_debug disk
# 6. Remove the disk
# 7. Check that pool is SUSPENDED
# 8. Add the disk back in
# 9. Clear errors and destroy the pools
