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

**Date:** 2025-01-20  
**Status:** ⚠️ Migration Blocked - Storage Configuration Issue  
**Issue:** Source storage (thin1) is disabled on r630-02

---

## Migration Requirements

### VMs to Migrate

**VMIDs 100-130 (7 containers):** 96 GB total
- 100, 101, 102, 103, 104, 105, 130

**VMIDs 7800-7811 (5 containers):** 210 GB total  
- 7800, 7801, 7802, 7810, 7811

**Total:** 306 GB required

### r630-01 Storage Available

- **thin1:** 208 GB (sufficient for VMIDs 100-130)
- **local-lvm:** 200 GB
- **local:** 536 GB (sufficient for VMIDs 7800-7811)
- **Total:** 944 GB (more than sufficient)

## Current Blocking Issue

### Problem: thin1 Storage Disabled on r630-02

**Issue:**
- VMs on r630-02 use `thin1` storage
- thin1 storage shows as **disabled** on r630-02
- vzdump backup fails: "storage 'thin1' is not available on node 'r630-02'"
- Direct migration fails with same error

**Storage Status on r630-02:**
```
thin1: disabled (but has volumes!)
thin4: active (has VMIDs 7800-7811)
```

---

## Solution Options

### Option 1: Enable thin1 Storage on r630-02 (Recommended)

Enable thin1 storage on r630-02 so backups can work:

1. Check thin1 configuration on r630-02
2. Enable thin1 storage
3. Then perform backup/restore migration

**Pros:** Allows standard backup/restore method  
**Cons:** Requires fixing storage configuration first

### Option 2: Change VM Storage Before Migration

1. Change VM storage to `local` (directory storage, always available)
2. Then migrate normally
3. Optionally change storage on target if needed

**Pros:** Works around the disabled storage issue  
**Cons:** Requires storage change operation first

### Option 3: Manual Storage Volume Copy (Complex)

1. Use LVM commands to copy storage volumes
2. Move/copy VM configs
3. Complex and risky

**Pros:** Direct volume copying  
**Cons:** Very complex, error-prone

## Recommended Approach

### Step 1: Enable thin1 Storage on r630-02

Fix the storage configuration so backups can work:

```bash
# On r630-02
# Check thin1 configuration
cat /etc/pve/storage.cfg | grep -A 6 "lvmthin: thin1"

# Enable thin1 storage
pvesm set thin1 --disable 0
```

### Step 2: Perform Migration

Once thin1 is enabled, use backup/restore method:

**VMIDs 100-130 → thin1 on r630-01:**
```bash
for vmid in 100 101 102 103 104 105 130; do
    vzdump $vmid --storage local --node r630-02 --compress gzip --mode stop
    BACKUP=$(ls -t /var/lib/vz/dump/vzdump-lxc-$vmid-*.tar.gz | head -1)
    pct restore $vmid $BACKUP --storage thin1 --target r630-01
    pct destroy $vmid  # on source
done
```

**VMIDs 7800-7811 → local on r630-01:**
```bash
for vmid in 7800 7801 7802 7810 7811; do
    vzdump $vmid --storage local --node r630-02 --compress gzip --mode stop
    BACKUP=$(ls -t /var/lib/vz/dump/vzdump-lxc-$vmid-*.tar.gz | head -1)
    pct restore $vmid $BACKUP --storage local --target r630-01
    pct destroy $vmid  # on source
done
```

## Current Status

- ✅ Storage capacity verified (sufficient)
- ✅ Migration plan created
- ⚠️ **Blocked:** thin1 storage disabled on r630-02
- ⏳ **Next Step:** Enable thin1 storage on r630-02

---

## Next Steps

1. **Enable thin1 storage on r630-02**
2. **Verify backup works**
3. **Perform migration using backup/restore**
4. **Verify VMs on r630-01**
