> **Note:** sda (447G Patriot Burst) is the OS drive — not part of the ZFS pool.

## Pool Plan (From zfs-casaos.md)

### Main Pool ("tank")
- **Vdev 1:** 5×4TB raidz2 → ~12TB usable, 2-drive redundancy
- **Vdev 2:** 3×3TB raidz1 → ~6TB usable, 1-drive redundancy

### Backup (standalone, NOT in main pool)
- 8TB + 10TB → standalone backup targets, format TBD

## Testing Pipeline

### Phase 1: SMART Long Test
```bash
smartctl -t long /dev/sdX
smartctl -H /dev/sdX  # check result
smartctl -a /dev/sdX > smart-$(basename sdX)-$(date +%Y%m%d).log
```

### Phase 2: badblocks (non-destructive)
```bash
badblocks -nvs /dev/sdX > badblocks-$(basename sdX)-$(date +%Y%m%d).log
```

### Pass/Fail Criteria
- ✅ **PASS:** Reallocated=0, Pending=0, Uncorrectable=0, badblocks=0/0/0
- ⚠️ **CONDITIONAL:** Any reallocated/pending sectors → demote to non-critical vdev
- ❌ **FAIL:** Any uncorrectable errors, badblocks bad sectors, SMART health=FAILED → retire

## Key Metrics to Watch
| Attribute | Warning | Critical |
|-----------|---------|----------|
| Reallocated Sectors (5) | >0 | >100 |
| Current Pending (197) | >0 | >10 |
| Uncorrectable Errors (198) | >0 | any |
| Power-On Hours (9) | — | >50,000 |
| Temperature (194) | >40°C | >45°C |
| Power Cycle Count (12) | — | high = old/used |

## Current Batch Schedule
| Batch | Drives | Status |
|-------|--------|--------|
| 1 | sdb, sde | ✅ Done |
| 2 | sdc, sdd | Mounted — test when safe |
| 3-4 | Cold 4TB×4 | Need to power up and swap |
| 5 | 3×3TB | Cold — TBD |

## Next Steps
- [ ] Identify cold drives — get model/serial for drives 5-11
- [ ] Run SMART tests on sdc, sdd (mounted, in use)
- [ ] Power up and test cold drives in batches
- [ ] Get exact drive models for all cold storage
- [ ] Set up smartd monitoring once testing complete
- [ ] Build pool on new rig when hardware arrives
