So you're running vgchange in a loop, which suggests that the lvm2-activation.service and lvm2-activation-early.service unitsas shipped by lvm2 are not sufficient. Those are supposed to run vgchange. I notice, that the /etc/init.d/lvm2 init script has Should-Start: mdadm-raid but the systemd unit files have no such ordering. I wonder, if that makes a difference. Could you copy /lib/systemd/system/lvm2-activation.service to /etc/systemd/system and add a line After=mdadm-raid.service to the [Unit] section. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
