### Configuration
```bash
# Multi-node configuration
PROXMOX_NODES="pve,pve2,pve3"
NODE_ASSIGNMENT_STRATEGY="auto"  # auto, round-robin, manual
```

### Scripts

- ✅ `scripts/manage/migrate-container.sh` - Container migration
- ✅ Enhanced `lib/proxmox-api.sh` - Multi-node API support

## ✅ Elastic Storage

### Implemented Features
- ✅ **Dynamic Expansion**: Expand container storage without downtime
- ✅ **Storage Pool Support**: Multiple storage pools (local-lvm, local-zfs, shared)
- ✅ **Automatic Monitoring**: Storage usage monitoring and alerts
- ✅ **Filesystem Expansion**: Automatic filesystem expansion after disk expansion

### Configuration
```bash
# Storage configuration
PROXMOX_STORAGE="local-lvm"
PROXMOX_STORAGE_POOLS="local-lvm,local-zfs,shared-storage"
STORAGE_EXPANSION_ENABLED="true"
STORAGE_ALERT_THRESHOLD="80"
STORAGE_EXPANSION_INCREMENT="50"
AUTO_EXPAND_STORAGE="false"  # Enable for automatic expansion
```

### Scripts
- ✅ `scripts/manage/expand-storage.sh` - Storage expansion utility
- ✅ Enhanced API functions for storage management

### Usage
```bash
# Expand container storage
./scripts/manage/expand-storage.sh <VMID> <additional_GB>

# Example
./scripts/manage/expand-storage.sh 106 50  # Add 50GB to container 106
```

## ✅ Container Migration

### Implemented Features
- ✅ **Live Migration**: Move containers between nodes with minimal downtime
- ✅ **Storage Migration**: Option to migrate storage along with container
- ✅ **Migration Verification**: Automatic verification after migration
- ✅ **Node Selection**: Automatic node discovery and selection

### Usage
```bash
# Migrate container
./scripts/manage/migrate-container.sh <VMID> <target_node> [storage] [migrate_storage]

# Examples
./scripts/manage/migrate-container.sh 106 pve2
./scripts/manage/migrate-container.sh 115 pve3 local-lvm true
```
