  36 # DESCRIPTION:
  37 # A ZFS file system is limited by the amount of disk space
  38 # available to the pool. Growing the pool by adding a disk
  39 # increases the amount of space.
  40 #
  41 # STRATEGY:
  42 # 1) Fill a ZFS filesystem mirror/raidz until ENOSPC by creating lots
  43 # of files
  44 # 2) Grow the mirror/raidz by adding a disk
  45 # 3) Verify that more data can now be written to the file system
