| # DESCRIPTION: |
| # Verify allowed striped widths (data+parity) and hot spares may be |
| # configured at pool creation time. |
| # |
| # STRATEGY: |
| # 1) Test valid stripe/spare combinations given the number of children. |
| # 2) Test invalid stripe/spare/children combinations outside the allow limits. |
