I did not catch the beginning of this thread so I don't know if this is
the information you want.  I'm guessing that you have this new partition
that you want added to your existing volume group.

First you can go to: http://tldp.org/HOWTO/LVM-HOWTO/

Here are the steps as I see them:

pvcreate /dev/hdd4 (?)
vgextend my_volume_group /dev/hdd4
umount /dev/my_volume_group/my_logical_volume
resize2fs /dev/my_volume_group/my_logical_volume
mount /dev/my_volume_group/my_logical_volume /my_mount_point

Hope that helps.
