Logical Volumes are not being disabled

Lines 47 to 56 in a927262

	# disable any active LVM partitions
	lvs=$(lvs --noheadings --rows | head -n1)
	if [ ! -z "$lvs" ]; then
	echo -n "Deactivating LVM volumes ... "
	for lv in $lvs
	do
	lvchange -an $lv > /dev/null 2>&1
	done
	echo -e "${green}done${normalText}"
	fi

I think, there is an error here: lvchange -an requires VG, not LV.
(And suppressing error output is also not a good idea)
