  36 # DESCRIPTION:
  37 #
  38 # A reservation cannot exceed the quota on a dataset
  39 #
  40 # STRATEGY:
  41 # 1) Create a filesystem and volume
  42 # 2) Set a quota on the filesystem
  43 # 3) Attempt to set a reservation larger than the quota. Verify
  44 # that the attempt fails.
  45 # 4) Repeat 2-3 for volume
  46 #
