  36 # DESCRIPTION:
  37 # The primary side of a zpool mirror can be zeroed without causing damage
  38 # to the data in the pool
  39 #
  40 # STRATEGY:
  41 # 1) Write several files to the ZFS filesystem mirror
  42 # 2) dd from /dev/zero over the primary side of the mirror
  43 # 3) verify that all the file contents are unchanged on the file system
