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