The new lvm2-pvscan@.service is responsible for on-demand execution of "pvscan --cache --activate ay" which causes lvmetad to be updated and LVM activation done if the VG is complete. Also, use udev-systemd mechanism to instantiate the job as the lvm2-pvscan@$devnode.service on each newly appeared PV in the system. This prevents the background job to be killed (that would happen if it was directly forked from udev rule - this behaviour is seen in recent versions of udev with the help of systemd that can track detached processes - the detached process would still be in the same cgroup). To enable this official udev-systemd protocol for instantiating background jobs, use new --enable-udev-systemd-background-jobs configure switch (it's disabled by default). This option is highly recommended wherever systemd is used!
