#
# ID: zfs_unshare_001_pos
#
# DESCRIPTION:
# Verify that 'zfs unshare <filesystem|mountpoint>' unshares a given shared 
# filesystem.
#
# STRATEGY:
# 1. Share filesystems
# 2. Invoke 'zfs unshare <filesystem|mountpoint>' to unshare zfs file system
# 3. Verify that the file system is unshared
# 4. Verify that unsharing an unshared file system fails
# 5. Verify that "zfs unshare -a" succeeds to unshare all zfs file systems.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-18)
#
# __stc_assertion_end
