Re: [arch-general] mdmonitor.service failed to start

But the new problem is: Why this service automatically start? I never manually enabled mdmonitor, and I cannot find its link in /etc/systemd/system/ . OK, it seems that the unit is somehow a dependence for some other units: $ systemctl is-enabled mdmonitor static

And I just masked that service to force prevent it from auto start. Problem 'solved'. Regards.
