# DESCRIPTION:
# Setting valid canmount to filesystem, it is successful.
# Whatever is set to volume or snapshot, it is failed.
# 'zfs set canmount=noauto <fs>'
#
# STRATEGY:
# 1. Setup a pool and create fs, volume, snapshot clone within it.
# 2. Set canmount=noauto for each dataset and check the retuen value
#    and check if it still can be mounted by mount -a.
# 3. mount each dataset(except volume) to see if it can be mounted.
