Author RAID setup during Debian lenny installation

- My Task -----

Fresh install of Debian lenny (Nov 11) installed on blank (zero'd out)
drives

I'm trying to build a very simple configuration, as follows.

Physical drives: 1x500gig PATA (hda), 2x500gig SATA (sda, sdb), 1x120gig
PATA (hdc)


- Partitions -----

hda1 - Primary, 500meg, swap
hda2 - Primary, 499gig, md1 (RAID5)

hdc1 - Primary, 120gig, /mnt/backup (Used to back up important files to)

sda1 - Primary, 400meg, swap
sda2 - Primary, 100meg, md0 (RAID1)
sda3 - Primary, 499gig, md1 (RAID5)

sdb1 - Primary, 400meg, swap
sdb2 - Primary, 100meg, md0 (RAID1)
sdb3 - Primary, 499gig, md1 (RAID5)


- Raid -----

md0 - formatted ext3, /boot
md1 - Logical volume, 998gig, lv0


- Logical Volume -----

lv0 - formatted xfs, /


- The Problem -----

At the partitioning stage of the installation, I create the three RAID
partitions that will hold md1. I then attempt to create the RAID5 array and
I'm told that I only have TWO RAID partitions available. At this point I
choose to delete a RAID array and I'm given five choice (even though there
hasn't been a RAID created yet). The choices are "md1", ":", "hda2[0]",
md0_raid1 and "Cancel".

You can see photos of my progress at:

One item to note... I have no problems created my RAID1 array, but then when
I try the RAID5 I see the same problems as above.


So...

- Is there a flaw in my partitioning scheme? All three RAID5 arrays are the
same size.
- Why can't I create my RAID5 array? I haven't found any references to bugs
here.
- I'm going to download a LIVE CD for some distro (still deciding) and will
try to partition the drive using that, then keep the partition layout during
the Debian installation. Does this sound reasonable?

Regarding my post below...

I ended up giving up on installing /boot onto a RAID1 array. Things are
flying along now.
