Hi hw
You might want to *start* with using the expert install - found under the
advanced menu option. That will give you more control, including advanced
partitioning.

I'd suggest that you partition one disk with "all files in one partition"
as a test run to see the sizes you'll need and then rerun the partitioner.

a root partition of (the rest - 1G) and then a 1G swap.
If you partition both disks to have an EFI partition at the beginning, then
a RAID partition, then 2 x 1G swap at the end.
Then use the RAID manager to set up RAID1 and LVM over the top. I'm unsure how
you would install GRUB to the second disk of the RAID - it might be that you'd
need to restart once the install is complete, use the rescue option and
specifically install GRUB on the second disk of the RAID.

Then you have wider problems than just installation, perhaps?

You do know that this is a general purpose installer that covers 12 or so
filesystem types and allows for flexibility?
