### VM Storage Sizes

| VMID | Name | Current Storage | Size |
|------|------|----------------|------|
| 100 | proxmox-mail-gateway | thin1 | 10 GB |
| 101 | proxmox-datacenter-manager | thin1 | 10 GB |
| 102 | cloudflared | thin1 | 2 GB |

## r630-01 Storage Capacity

### Available Storage

| Storage | Type | Status | Total | Used | Available |
|---------|------|--------|-------|------|-----------|
| **local-lvm** | lvmthin | ✅ Active | 200 GB | 0 GB | **200 GB** |
| thin1 | lvmthin | ❌ Disabled | 208 GB | - | - |
| local | dir | ✅ Active | 536 GB | 0 GB | 536 GB |

### Storage Analysis

**Recommended Storage:** `local-lvm`
- ✅ Active and ready
- ✅ 200 GB available (sufficient for 96 GB requirement)
- ✅ LVM thin provisioning (efficient)
- ✅ Standard storage name

**Alternative Storage:** `local` (directory storage)
- ✅ 536 GB available (more than sufficient)
- ⚠️ Slower performance than LVM thin
- ⚠️ Less efficient space usage

---

## Migration Feasibility

### ✅ Storage: SUFFICIENT

- **Required:** 96 GB
- **Available (local-lvm):** 200 GB
- **Margin:** 104 GB free after migration
- **Status:** ✅ **Sufficient storage available**

### ✅ Current Load: LOW

- **Current VMs on r630-01:** 0
- **After Migration:** 7 containers
- **Status:** ✅ **Low load, can handle migration**

### ✅ Resources: EXCELLENT

- **CPU:** 32 cores @ 2.40GHz (excellent)
- **Memory:** 503 GB (1% used, 99% free)
- **Status:** ✅ **Excellent resources available**

---

## Migration Plan

### Pre-Migration Checklist

- [x] Storage capacity verified ✅
- [x] Storage type confirmed (local-lvm) ✅
- [x] Target node resources verified ✅
- [ ] Source VMs status checked (currently stopped)
- [ ] Network connectivity verified
- [ ] Backup plan prepared

### Migration Steps

1. **Verify Source VMs**
   ```bash
   ssh root@192.168.11.12
   pct list | grep -E '100|101|102|103|104|105|130'
   ```

2. **Verify Target Storage**
   ```bash
   ssh root@192.168.11.11
   pvesm status local-lvm
   ```

3. **Migrate VMs**
   ```bash
   # From r630-02 (or ml110)
   for vmid in 100 101 102 103 104 105 130; do
       pct migrate $vmid r630-01 --storage local-lvm
   done
   ```

4. **Verify Migration**
   ```bash
   ssh root@192.168.11.11
   pct list
   ```

## Storage Breakdown

### Before Migration

**r630-01:**
- local-lvm: 200 GB available
- Used: 0 GB

**r630-02:**
- thin1: 124 GB used (52.35%)
- thin4: 38 GB used (16.03%)

### After Migration

**r630-01:**
- local-lvm: 104 GB available (200 GB - 96 GB)
- Used: 96 GB (7 containers)

**r630-02:**
- thin1: ~28 GB used (reduced by 96 GB)
- thin4: 38 GB used (unchanged)

---

## Recommendations

### ✅ Recommended: Proceed with Migration

**Reasons:**
1. **Sufficient Storage:** 200 GB available, only 96 GB needed
2. **Excellent Resources:** 32 cores, 503 GB RAM
3. **Low Load:** No current VMs on r630-01
4. **Storage Type:** LVM thin is optimal for containers

### Storage Strategy

**Use `local-lvm` for migration:**
- Best performance (LVM thin provisioning)
- Efficient space usage
- Standard storage name
- Sufficient capacity (200 GB > 96 GB required)

## Migration Commands

### Full Migration Script

```bash
#!/bin/bash
# Migrate VMIDs 100-130 from r630-02 to r630-01

SOURCE_NODE="r630-02"
TARGET_NODE="r630-01"
TARGET_STORAGE="local-lvm"
VMIDS=(100 101 102 103 104 105 130)

echo "Migrating VMs from $SOURCE_NODE to $TARGET_NODE"
echo "Target storage: $TARGET_STORAGE"
echo ""

for vmid in "${VMIDS[@]}"; do
    echo "Migrating VMID $vmid..."
    pct migrate $vmid $TARGET_NODE --storage $TARGET_STORAGE
    if [ $? -eq 0 ]; then
        echo "  ✓ VMID $vmid migrated successfully"
    else
        echo "  ✗ VMID $vmid migration failed"
    fi
    echo ""
done

echo "Migration complete!"
echo "Verifying on $TARGET_NODE..."
ssh root@192.168.11.11 "pct list"
```

---

## Verification Steps

### Pre-Migration
```bash
# Check source VMs
ssh root@192.168.11.12
pct list | grep -E '100|101|102|103|104|105|130'

# Check target storage
ssh root@192.168.11.11
pvesm status local-lvm
```

### Post-Migration
```bash
# Verify VMs on target
ssh root@192.168.11.11
pct list | grep -E '100|101|102|103|104|105|130'

# Check storage usage
pvesm status local-lvm

# Verify VM configurations
for vmid in 100 101 102 103 104 105 130; do
    pct config $vmid
done
```
