# DESCRIPTION:
# Setting a valid snapdir on a dataset, it should be successful.
#
# STRATEGY:
# 1. Create pool, then create filesystem and volume within it.
# 2. Create a snapshot for each dataset.
# 3. Setting different valid snapdir to each dataset.
# 4. Check the return value and make sure it is 0.
# 5. Verify .zfs directory is hidden|visible according to the snapdir setting.
