That check breaks with no or more than 1 LV but anyway, we should bail
out even on non active VG, it's not nice to reformat the disk under
LVM feet, so just first check is enough:

if [ "$(pvs -o vg_name --noheadings $dev $dev[0-9]* 2>/dev/null)" ]; then
	echo "Device, $dev, contains a volume group and cannot be formated!"
