Adastra VTL Service Status

✅ Service Fixed!

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

Service Status

systemctl status mhvtl
● mhvtl.service - mhvtl Virtual Tape Library
     Active: active (exited)

What Was Fixed

Queue Number Issue: vtltape requires -q <number> argument, not just -q
Lock File Cleanup: Added automatic cleanup of stale lock files in /var/lock/mhvtl/
Error Handling: Script now handles errors gracefully without failing the service
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.
