  36 # DESCRIPTION:
  37 #       Verify that the space used by multiple copies is charged correctly
  38 #
  39 # STRATEGY:
  40 #       1. Create filesystems with copies set as 2,3 respectively;
  41 #       2. Copy specified size data into each filesystem;
  42 #       3. Verify that the space is charged as expected with zfs list, ls -s, df(1m),
  43 #          du(1) commands;
  44 #
