IgnoreOnIsolate=true [Service] # The mdmon starting in the initramfs (with dracut at least) # cannot see sysfs after root is mounted, so we will have to # 'takeover'. As the '--offroot --takeover' don't hurt when # not necessary, are are useful with root-on-md in dracut, # have them always present. ExecStart=/usr/sbin/mdmon --foreground --offroot --takeover %I # Don't set the PIDFile. It isn't necessary (systemd can work # it out) and systemd will remove it when transitioning from # initramfs to rootfs. #PIDFile=/run/mdadm/%I.pid # The default slice is system-mdmon.slice which Conflicts # with shutdown, causing mdmon to exit early. So use system.slice. Slice=system.slice Save
