  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
