  26 # DESCRIPTION:
  27 # Verify that the dnode sizes of newly created files are consistent
  28 # with the dnodesize dataset property.
  29 #
  30 # STRATEGY:
  31 # 1. Create a file system
  32 # 2. Set dnodesize to a legal literal value
  33 # 3. Create a file
  34 # 4. Repeat 2-3 for all legal literal values of dnodesize values
  35 # 5. Unmount the file system
  36 # 6. Use zdb to check expected dnode sizes
  37 #
