new udev rule 69-dm-lvm.rules replaces 69-dm-lvm-meta.rules and lvm2-pvscan.service udev rule calls pvscan directly on the added device pvscan output indicates if a complete VG can be activated udev env var LVM_VG_NAME_COMPLETE is used to pass complete VG name from pvscan to the udev rule udev rule uses systemd-run to run vgchange -aay <vgname>
