35#
36# DESCRIPTION:
37# Setting valid canmount to filesystem, it is successful.
38# Whatever is set to volume or snapshot, it is failed.
39# 'zfs set canmount=noauto <fs>'
40#
41# STRATEGY:
42# 1. Setup a pool and create fs, volume, snapshot clone within it.
43# 2. Set canmount=noauto for each dataset and check the retuen value
44#    and check if it still can be mounted by mount -a.
45# 3. mount each dataset(except volume) to see if it can be mounted.
46#
47# TESTABILITY: explicit
48#
49# TEST_AUTOMATION_LEVEL: automated
50#
51# CODING_STATUS: COMPLETED (2008-03-05)
