38#
39# DESCRIPTION:
40# Setting valid canmount to filesystem, it is successful.
41# Whatever is set to volume or snapshot, it is failed.
42# 'zfs set canmount=noauto <fs>'
43#
44# STRATEGY:
45# 1. Setup a pool and create fs, volume, snapshot clone within it.
46# 2. Set canmount=noauto for each dataset and check the retuen value
47#    and check if it still can be mounted by mount -a.
48# 3. mount each dataset(except volume) to see if it can be mounted.
49#
50# TESTABILITY: explicit
51#
52# TEST_AUTOMATION_LEVEL: automated
53#
54# CODING_STATUS: COMPLETED (2008-03-05)
