Hm. Why /dev/hda2 if there are no partitions?

pvcreate /dev/hda && vgcreate VG /dev/hda && ....

You normally don't do that. One of the "key techniques" of using
LVM in a successful way, is to make the logical volumes and thus
the file systems only as big as needed, leaving unallocated space
in the VG which can then, later, be allocated to a logical volume.
