The following is a single, integrated example showing the clearpart, raid, part, volgroup, and logvol kickstart options in action:

clearpart --drives=hda,hdc --initlabel

# Raid 1 IDE config
part raid.11    --size 1000     --asprimary     --ondrive=hda
part raid.12    --size 1000     --asprimary     --ondrive=hda
part raid.13    --size 2000     --asprimary     --ondrive=hda
part raid.14    --size 8000                     --ondrive=hda
part raid.15    --size 1 --grow                 --ondrive=hda
           
part raid.21    --size 1000     --asprimary     --ondrive=hdc
part raid.22    --size 1000     --asprimary     --ondrive=hdc
part raid.23    --size 2000     --asprimary     --ondrive=hdc
part raid.24    --size 8000                     --ondrive=hdc
part raid.25    --size 1 --grow                 --ondrive=hdc

# You can add --spares=x 
raid /          --fstype ext3 --device md0 --level=RAID1 raid.11 raid.21
raid /safe      --fstype ext3 --device md1 --level=RAID1 raid.12 raid.22
raid swap       --fstype swap --device md2 --level=RAID1 raid.13 raid.23
raid /usr       --fstype ext3 --device md3 --level=RAID1 raid.14 raid.24
raid pv.01      --fstype ext3 --device md4 --level=RAID1 raid.15 raid.25

# LVM configuration so that we can resize /var and /usr/local later
volgroup sysvg pv.01    
logvol /var             --vgname=sysvg  --size=8000     --name=var
logvol /var/freespace   --vgname=sysvg  --size=8000     --name=freespacetouse
logvol /usr/local       --vgname=sysvg  --size=1 --grow --name=usrlocal

This advanced example implements LVM over RAID, as well as the ability to resize various directories for future growth.
