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