| # DESCRIPTION: |
| # Verify scrub behaves as intended when contending with a healing or |
| # sequential resilver. |
| # |
| # STRATEGY: |
| # 1. Create a pool |
| # 2. Add a modest amount of data to the pool. |
| # 3. For healing and sequential resilver: |
| # a. Start scrubbing. |
| # b. Verify a resilver can be started and it cancels the scrub. |
| # c. Verify a scrub cannot be started when resilvering |
| # |
