35# DESCRIPTION:
36# Verify that zfs unmount and destroy in a snapshot directory will not cause error.
37#
38# STRATEGY:
39# 1. Create a file in a zfs filesystem, snapshot it and change directory to snapshot directory
40# 2. Verify that 'zfs unmount -a'  will fail and 'zfs unmount -fa' will succeed
41# 3. Verify 'ls' and 'cd /' will succeed
42# 4. 'zfs mount -a' and change directory to snapshot directory again
43# 5. Verify that zfs destroy snapshot will succeed
44# 6. Verify 'ls' and 'cd /' will succeed
45# 7. Create zfs filesystem, create a file, snapshot it and change to snapshot directory
46# 8. Verify that zpool destroy the pool will succeed
47# 9. Verify 'ls' 'cd /' 'zpool list' and etc will succeed
48#
49# TESTABILITY: explicit
50#
51# TEST_AUTOMATION_LEVEL: automated
52#
53# CODING_STATUS: COMPLETED (2008-07-29)
