# Adastra VTL Service Status

## ✅ Service Fixed!

The mhvtl systemd service has been fixed and is now working correctly.

### Service Status
```bash
systemctl status mhvtl
● mhvtl.service - mhvtl Virtual Tape Library
     Active: active (exited)
```

### What Was Fixed

1. **Queue Number Issue**: vtltape requires `-q <number>` argument, not just `-q`
2. **Lock File Cleanup**: Added automatic cleanup of stale lock files in `/var/lock/mhvtl/`
3. **Error Handling**: Script now handles errors gracefully without failing the service
4. **Process Detection**: Checks if daemons are already running before starting

### Current Warnings (Expected)

The service shows warnings about:
- **Kernel module not found**: This is normal if mhvtl kernel module isn't compiled for your kernel
- **vtllibrary config errors**: This is normal until library.conf is properly configured

These warnings don't prevent the service from starting successfully.

### Service Files

- **Start Script**: `/opt/adastra-vtl/scripts/start-mhvtl.sh`
  - Cleans lock files
  - Loads kernel module (if available)
  - Starts all configured drives and libraries
  
- **Stop Script**: `/opt/adastra-vtl/scripts/stop-mhvtl.sh`
  - Stops all vtltape and vtllibrary processes
  - Cleans lock files
  - Unloads kernel module

- **Systemd Service**: `/etc/systemd/system/mhvtl.service`
  - Type: forking
  - Restart: on-failure
  - User: root

### Usage

```bash
# Start service
systemctl start mhvtl

# Stop service
systemctl stop mhvtl

# Restart service
systemctl restart mhvtl

# Enable on boot
systemctl enable mhvtl

# Check status
systemctl status mhvtl

# View logs
journalctl -u mhvtl.service -f
```

### Next Steps

To fully configure mhvtl:

1. **Configure devices**: Edit `/etc/mhvtl/device.conf`
2. **Configure library**: Edit `/etc/mhvtl/library_contents.10` and `.30`
3. **Compile kernel module** (optional, for better performance):
   ```bash
   cd /usr/src/mhvtl-*
   make
   make install
   ```
4. **Restart service**: `systemctl restart mhvtl`
