31# DESCRIPTION:
32# Verify that the dnode sizes of newly created files are consistent
33# with the dnodesize dataset property.
34#
35# STRATEGY:
36# 1. Create a file system
37# 2. Set dnodesize to a legal literal value
38# 3. Create a file
39# 4. Repeat 2-3 for all legal literal values of dnodesize values
40# 5. Unmount the file system
41# 6. Use zdb to check expected dnode sizes
42#
