Ok, that clarifies that the VG on /dev/hda3 is not in use at all and your 
CentOS is indeed installed on the LV on hda9. I still wonder how this mess 
was created. Did you have an earlier Linux installation on it and forgot 
to wipe that completely before you installed CentOS?
I think the easiest way to get you back on track is to edit your fstab. 
There is a line about /boot in it that points to /dev/hda3. Change that to 
/dev/hda8. This is all.
But before you do that, please check that there is indeed a grub.conf on 
it that contains the "old" information. You know the path I gave you was 
slightly wrong. Once you have confirmed that you can make the change to 
fstab (/etc/fstab). Be really careful when you do that as the wrong 
changes can make your system unbootable.
Once the change is done the *next* kernel that gets installed will go to 
the correct boot partition and the correct grub.conf will be updated with 
the correct information to boot with the new kernel.
