| # DESCRIPTION: |
| # Verify that zfs unmount and destroy in a snapshot directory will not cause error. |
| # |
| # STRATEGY: |
| # 1. Create a file in a zfs filesystem, snapshot it and change directory to snapshot directory |
| # 2. Verify that 'zfs unmount -a' will fail and 'zfs unmount -fa' will succeed |
| # 3. Verify 'ls' and 'cd /' will succeed |
| # 4. 'zfs mount -a' and change directory to snapshot directory again |
| # 5. Verify that zfs destroy snapshot will succeed |
| # 6. Verify 'ls' and 'cd /' will succeed |
| # 7. Create zfs filesystem, create a file, snapshot it and change to snapshot directory |
| # 8. Verify that zpool destroy the pool will succeed |
| # 9. Verify 'ls' 'cd /' 'zpool list' and etc will succeed |
| # |
