  36 # DESCRIPTION:
  37 # A zvol volume will return ENOSPC when the underlying pool runs out of
  38 # space.
  39 #
  40 # STRATEGY:
  41 # 1. Create a pool
  42 # 2. Create a zvol volume
  43 # 3. Create a ufs file system ontop of the zvol
  44 # 4. Mount the ufs file system
  45 # 5. Fill volume until ENOSPC is returned
