36# DESCRIPTION:
37# Invoke "zfs mount <filesystem>" with a filesystem
38# but its mountpoint is currently in use,
39# it will fail with a return code of 1
40# and issue an error message.
41#
42# STRATEGY:
43# 1. Make sure that the ZFS filesystem is unmounted.
44# 2. Apply 'zfs set mountpoint=path <filesystem>'.
45# 3. Change directory to that given mountpoint.
46# 3. Invoke 'zfs mount <filesystem>'.
47# 4. Verify that mount failed with return code of 1.
