| # |
| # DESCRIPTION: |
| # Ensure that we can expand a device while the pool has a |
| # checkpoint but in the case of a rewind that device rewinds |
| # back to its previous size. |
| # |
| # STRATEGY: |
| # 1. Create pool |
| # 2. Populate it |
| # 3. Take checkpoint |
| # 4. Expand the device and modify some data |
| # (include at least one destructive change) |
| # 5. Rewind to checkpoint |
| # 6. Verify that we rewinded successfully and check if the |
| # device shows up expanded in the vdev list |
| # |
