  36 # DESCRIPTION:
  37 #       Verify 'zfs destroy -f' succeeds as root.
  38 #
  39 # STRATEGY:
  40 #       1. Create filesystem in the storage pool
  41 #       2. Set mountpoint for the filesystem and make it busy
  42 #       3. Verify that 'zfs destroy' fails to destroy the filesystem
  43 #       4. Verify 'zfs destroy -f' succeeds to destroy the filesystem.
