You create the partitions in the installer, setting the partition use to
'raid'. You then select configure raid, and setup all your raid devices.
Then when you return to the partition tool you will see the new raid
md devices, which you then set to 'use as LVM volume', then you go to
configure logical volume management, and setup your lvm volumes there
for your actual file systems, then when you come back to the partition
tool again you will see the lvm volumes listed and you can select them
and pick the filesystem type and mountpoint for each LVM volume.
