# ID: zfs_mount_005_pos
#
# DESCRIPTION:
# Invoke "zfs mount <filesystem>" with a filesystem
# but its mountpoint is currently in use,
# it will fail with a return code of 1
# and issue an error message.
#
# STRATEGY:
# 1. Make sure that the ZFS filesystem is unmounted.
# 2. Apply 'zfs set mountpoint=path <filesystem>'.
# 3. Change directory to that given mountpoint.
# 3. Invoke 'zfs mount <filesystem>'.
# 4. Verify that mount failed with return code of 1.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
