# ID: zfs_mount_004_pos
#
# DESCRIPTION:
# Invoke "zfs mount <filesystem>" with a filesystem
# which has been already mounted,
# it will fail with a return code of 1
#
# STRATEGY:
# 1. Make sure that the ZFS filesystem is unmounted.
# 2. Invoke 'zfs mount <filesystem>'.
# 3. Verify that the filesystem is mounted.
# 4. Invoke 'zfs mount <filesystem>' the second times.
# 5. Verify the last mount operation failed with return code of 1.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
