# DESCRIPTION:
# Verify that a dataset could not be shared but filesystems are shared.
#
# STRATEGY:
# 1. Create a dataset and file system
# 2. Set the sharenfs property on the dataset
# 3. Verify that the dataset is unable be shared.
# 4. Add a new file system to the dataset.
# 5. Verify that the newly added file system be shared.
