40# DESCRIPTION:
41# Verify that zfs unmount and destroy in a snapshot directory will not cause error.
42#
43# STRATEGY:
44# 1. Create a file in a zfs filesystem, snapshot it and change directory to snapshot directory
45# 2. Verify that 'zfs unmount -a'  will fail and 'zfs unmount -fa' will succeed
46# 3. Verify 'ls' and 'cd /' will succeed
47# 4. 'zfs mount -a' and change directory to snapshot directory again
48# 5. Verify that zfs destroy snapshot will succeed
49# 6. Verify 'ls' and 'cd /' will succeed
50# 7. Create zfs filesystem, create a file, snapshot it and change to snapshot directory
51# 8. Verify that zpool destroy the pool will succeed
52# 9. Verify 'ls' 'cd /' 'zpool list' and etc will succeed
53#
54# TESTABILITY: explicit
55#
56# TEST_AUTOMATION_LEVEL: automated
57#
58# CODING_STATUS: COMPLETED (2008-07-29)
