# ID: zfs_share_001_pos
#
# DESCRIPTION:
# Verify that 'zfs set sharenfs' and 'zfs share' shares a given dataset.
#
# STRATEGY:
# 1. Invoke 'zfs set sharenfs'.
# 2. Verify that the file system is shared.
# 3. Invoke 'zfs share'.
# 4. Verify that the file system is shared.
# 5. Verify that a shared filesystem cannot be shared again.
# 6. Verify that share -a succeeds.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
