  32 # DESCRIPTION:
  33 #       Verify that the space used by multiple copies is charged correctly
  34 #
  35 # STRATEGY:
  36 #       1. Create filesystems with copies set as 2,3 respectively;
  37 #       2. Copy specified size data into each filesystem;
  38 #       3. Verify that the space is charged as expected with zfs list, ls -s, df(1m),
  39 #          du(1) commands;
  40 #
