| # DESCRIPTION: |
| # A pool should be importable when up to 2 top-level devices are missing. |
| # |
| # STRATEGY: |
| # 1. Create a pool. |
| # 2. Write some data to the pool and checksum it. |
| # 3. Add one or more devices. |
| # 4. Write more data to the pool and checksum it. |
| # 5. Export the pool. |
| # 6. Move added devices out of the devices directory. |
| # 7. Import the pool with missing devices. |
| # 8. Verify that the first batch of data is intact. |
| # 9. Verify that accessing the second batch of data doesn't suspend pool. |
| # 10. Export the pool, move back missing devices, Re-import the pool. |
| # 11. Verify that all the data is intact. |
