You are using LVM; there is no need to do anything drastic.

Change the partition types of hda1 and hda2 to "Linux LVM". Don't delete 
or merge the partitions together, or you will need to alter your 
grub.conf file to change partition numbers (not a big job, admittedly).

Then do:
# pvcreate /dev/hda1 /dev/hda2

You will now be able to use "vgextend" to add /dev/hda1 and /dev/hda2 to 
your existing logical volume (VolGroup00 by default):
# vgextend VolGroup00 /dev/hda1 /dev/hda2

"vgdisplay" should then show that you have additional 30G of free space 
in your volume group, which you can add to your existing logical 
volume(s), using "lvextend". You can then use resize2fs or ext2online to 
change the sizes of the ext2/3 filesystems on the logical volume(s) you 
have made bigger, to make use of the extra space.

Paul.
