| # DESCRIPTION: |
| # Once a pool has been exported, and one or more devices are |
| # damaged or missing (d/m), import should handle this kind of situation |
| # as described: |
| # - Regular, report error while any number of devices failing. |
| # - Mirror could withstand (N-1) devices failing |
| # before data integrity is compromised |
| # - Raidz could withstand one devices failing |
| # before data integrity is compromised |
| # Verify those are true. |
| # |
| # STRATEGY: |
| # 1. Create test pool upon device files using the various combinations. |
| # - Regular pool |
| # - Mirror |
| # - Raidz |
| # 2. Create necessary filesystem and test files. |
| # 3. Export the test pool. |
| # 4. Remove one or more devices |
| # 5. Verify 'zpool import' will handle d/m device successfully. |
| # Using the various combinations. |
| # - Regular import |
| # - Alternate Root Specified |
| # It should be succeed with single d/m device upon 'raidz' & 'mirror', |
| # but failed against 'regular' or more d/m devices. |
| # 6. If import succeed, verify following is true: |
| # - The pool shows up under 'zpool list'. |
| # - The pool's health should be DEGRADED. |
| # - It contains the correct test file |
| # |
