# 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`
### Web UI
Access the configuration web UI at:
```
http://[SERVER-IP]/mhvtl-config
```
The web UI provides a graphical interface to configure mhvtl devices and libraries.
