| # DESCRIPTION: |
| # Verify manual trim pool data integrity. |
| # |
| # STRATEGY: |
| # 1. Create a pool on sparse file vdevs to trim. |
| # 2. Generate some interesting pool data which can be trimmed. |
| # 3. Manually trim the pool. |
| # 4. Verify trim IOs of the expected type were issued for the pool. |
| # 5. Verify data integrity of the pool after trim. |
| # 6. Repeat test for striped, mirrored, and RAIDZ pools. |
