# Storage Migration Issue - pve2 Configuration

**Last Updated:** 2026-01-31  
**Document Version:** 1.0  
**Status:** Active Documentation

**Issue:** Container migrations failing due to storage configuration mismatch.

---

## Problem

Container migrations from ml110 to pve2 are failing with the error:
```
Volume group "pve" not found
ERROR: storage migration for 'local-lvm:vm-XXXX-disk-0' to storage 'local-lvm' failed
```

## Root Cause

**ml110** (source):
- Has `local-lvm` storage **active**
- Uses volume group named **"pve"** (standard Proxmox setup)
- Containers stored on `local-lvm:vm-XXXX-disk-0`

**pve2** (target):
- Has `local-lvm` storage but it's **INACTIVE**
- Has volume groups named **lvm1, lvm2, lvm3, lvm4, lvm5, lvm6** instead of "pve"
- Storage is not properly configured for Proxmox

## Storage Status

### ml110 Storage
```
local-lvm: lvmthin, active, 832GB total, 108GB used
Volume Group: pve (standard)
```

### pve2 Storage
```
local-lvm: lvmthin, INACTIVE, 0GB available
Volume Groups: lvm1, lvm2, lvm3, lvm4, lvm5, lvm6 (non-standard)
```

## Solutions

### Option 1: Configure pve2's local-lvm Storage (Recommended)

1. **Rename/create "pve" volume group on pve2**:
   ```bash
   # On pve2, check current LVM setup
   ssh root@192.168.11.12 "vgs; lvs"
   
   # Rename one of the volume groups to "pve" (if possible)
   # OR create a new "pve" volume group from available space
   ```

2. **Activate local-lvm storage on pve2**:
   ```bash
   # Check storage configuration
   ssh root@192.168.11.12 "cat /etc/pve/storage.cfg"
   
   # May need to reconfigure local-lvm to use correct volume group
   ```

### Option 2: Migrate to Different Storage on pve2

Use `local` (directory storage) instead of `local-lvm`:

```bash
# Migrate with storage specification
pct migrate <VMID> pve2 --storage local --restart
```

**Pros**: Works immediately, no storage reconfiguration needed  
**Cons**: Directory storage is slower than LVM thin provisioning

### Option 3: Use Shared Storage

Configure shared storage (NFS, Ceph, etc.) accessible from both nodes:

```bash
# Add shared storage to cluster
# Then migrate containers to shared storage
```

## Immediate Workaround

Until pve2's local-lvm is properly configured, we can:

1. **Skip migrations** for now
2. **Configure pve2 storage** first
3. **Then proceed with migrations**

## Next Steps

1. ⏳ Investigate pve2's LVM configuration
2. ⏳ Configure local-lvm storage on pve2 with "pve" volume group
3. ⏳ Verify storage is active and working
4. ⏳ Retry container migrations

## Verification Commands

```bash
# Check pve2 storage status
ssh root@192.168.11.12 "pvesm status"

# Check volume groups
ssh root@192.168.11.12 "vgs"

# Check local-lvm configuration
ssh root@192.168.11.12 "cat /etc/pve/storage.cfg | grep -A 5 local-lvm"
```
