# DESCRIPTION:
# Check that zpool labelclear will refuse to clear the label
# on ACTIVE vdevs of exported pool without -f, and will succeeded with -f.
#
# STRATEGY:
# 1. Create a pool with log device.
# 2. Export the pool.
# 3. Check that zpool labelclear returns non-zero when trying to
#    clear the label on ACTIVE vdevs, and succeeds with -f.
# 4. Add auxilary vdevs (cache/spare).
# 5. Check that zpool labelclear succeeds on auxilary vdevs of
#    exported pool.
