35# DESCRIPTION:
36# Verify that umount and destroy fail, and do not unshare the shared
37# file system
38#
39# STRATEGY:
40# 1. Share the filesystem via 'zfs set sharenfs'.
41# 2. Try umount failure, and verify that the file system is still shared.
42# 3. Try destroy failure, and verify that the file system is still shared.
