# ID: zfs_share_003_pos
#
# DESCRIPTION:
# Invoking "zfs share <file system>" with a file system
# whose sharenfs property is 'off' , will fail with a
# return code of 1 and issue an error message.
#
# STRATEGY:
# 1. Make sure that the ZFS file system is unshared.
# 2. Mount the file system using the various combinations
# - zfs set sharenfs=off <file system>
# - zfs set sharenfs=none <file system>
# 3. Verify that share failed with return code of 1.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
#
