lvextend only affects the partition. After extending a partition it
is necessary to run fsck and resizefs. Assuming ext3 the flow looks
something like this:
unmount /dev/vg1/lv1
lvextend -L+1G /dev/vg1/lv1
e2fsck -f /dev/vg1/lv1
resize2fs /dev/vg1/lv1
mount /dev/vg1/lv1
The LVM HOWTOs explain these fairly well.
