36# DESCRIPTION:
37# While canmount=noauto and  the dataset is mounted,
38# zfs must not attempt to unmount it.
39#
40# STRATEGY:
41# 1. Setup a pool and create fs, volume, snapshot clone within it.
42# 2. Set canmount=noauto for each dataset and check the return value
43#    and check if it still can not be unmounted when the dataset is mounted
