| # DESCRIPTION: |
| # Test /proc/spl/kstat/zfs/<pool>/state kstat |
| # |
| # STRATEGY: |
| # 1. Create a mirrored pool |
| # 2. Check that pool is ONLINE |
| # 3. Fault one disk |
| # 4. Check that pool is DEGRADED |
| # 5. Create a new pool with a single scsi_debug disk |
| # 6. Remove the disk |
| # 7. Check that pool is SUSPENDED |
| # 8. Add the disk back in |
| # 9. Clear errors and destroy the pools |
