# r630-01 Migration Complete - VMIDs 100-130 and 7800-7811

**Date:** 2025-01-20  
**Status:** ✅ Migration Complete  
**Method:** Backup/Restore using --dumpdir (bypasses storage config issue)

---

## Executive Summary

Successfully migrated **12 containers** from r630-02 to r630-01 using backup/restore method with `--dumpdir` parameter:
- **VMIDs 100-130 (7 containers)** → thin1 storage (96 GB)
- **VMIDs 7800-7811 (5 containers)** → local storage (210 GB)
- **Total:** 306 GB migrated

---

## Blocking Issue Resolution

### Problem
- Storage configuration mismatch: thin1 storage config said `vgname pve` but r630-02's thin1 uses VG `thin1`
- vzdump failed with "no such logical volume pve/thin1"

### Solution
- Used `vzdump --dumpdir` parameter to bypass storage configuration dependency
- This allows vzdump to work directly with volume paths without relying on storage config
- Backup/restore process completed successfully

## Migration Method

### Backup/Restore with --dumpdir

Used `vzdump --dumpdir` to bypass storage configuration issues:

```bash
# Backup (bypasses storage config)
vzdump <vmid> --dumpdir /var/lib/vz/dump --compress gzip --mode stop

# Restore
pct restore <vmid> /var/lib/vz/dump/vzdump-lxc-<vmid>-*.tar.gz \
    --storage <target-storage> \
    --target r630-01

# Cleanup
pct destroy <vmid>  # on source node
```

**Key Improvement:** Using `--dumpdir` instead of `--storage` allows vzdump to work even when storage configuration doesn't match actual volume groups.

## Storage Distribution

### r630-01 Storage Usage

| Storage | Type | Used | Available | VMs |
|---------|------|------|-----------|-----|
| thin1 | lvmthin | 96 GB | 112 GB | VMIDs 100-130 |
| local | dir | 210 GB | 326 GB | VMIDs 7800-7811 |
| **Total** | | **306 GB** | **438 GB** | **12 containers** |

---

## Verification

### Pre-Migration
- ✅ All 12 VMs verified on r630-02
- ✅ Storage capacity confirmed (944 GB available)
- ✅ All VMs in stopped state
- ✅ Blocking issue resolved (using --dumpdir)

### Post-Migration
- ✅ All 12 VMs verified on r630-01
- ✅ No VMs remaining on r630-02 for these VMIDs
- ✅ Storage usage confirmed
- ✅ VMs configured correctly

## Migration Script

**Script:** `scripts/migrate-vms-fixed.sh`

**Key Features:**
- Uses `--dumpdir` to bypass storage config issues
- Automated backup/restore for all VMs
- Error handling and verification
- Progress reporting
- Automatic cleanup

---

## Key Learnings

1. **--dumpdir Parameter:** Bypasses storage configuration dependency in vzdump
2. **Storage Config Issues:** Can be worked around using direct dump directory
3. **Backup/Restore Reliability:** Most reliable method when storage configurations don't match
4. **Storage Conversion:** Proxmox automatically converts storage types during restore

---

## Next Steps Completed

1. ✅ Fixed blocking issue (using --dumpdir)
2. ✅ Migrated all VMs
3. ✅ Verified migrations
4. ✅ Updated documentation

---

## Next Steps (Optional)

1. ⏳ **Verify VM functionality** - Start VMs and verify services
2. ⏳ **Monitor storage usage** - Track thin1 and local storage
3. ⏳ **Cleanup backups** - Remove backup files if no longer needed

**Last Updated:** 2025-01-20  
**Status:** ✅ **MIGRATION COMPLETE**  
**Method:** Backup/Restore with --dumpdir  
**Result:** All 12 containers successfully migrated to r630-01
