+# 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`
+

+
+The web UI provides a graphical interface to configure mhvtl devices and libraries.
