Lates debian installer on Squeeze Iso disk debian-6.0.0-amd64-BD-1.iso used to
install new computer.
I've created on sda and sdb the same partition configuration:
xen:~# fdisk -l /dev/sda /dev/sdb
Disk /dev/sda: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

At the moment the above two hds are available for installation. After migrating
something from the old two existing
hard drives with the same geometry I will add them in the system, too.
So I want to configure all md's with 4 drives where 2 are missing.
This is not configurable in debian installer at the moment so I created the
needed md's manually with mdadm command.
In short the command I used must be
mdadm --bitmap=internal --name=bootmd --level=1 --raid-devices=3 --spare-
devices=1 /dev/md125 /dev/sda1 /dev/sdb1 missing missing
mdadm --bitmap=internal --name=bootmd --level=1 --raid-devices=3 --spare-
devices=1 /dev/md126 /dev/sda2 /dev/sdb2 missing missing
mdadm --bitmap=internam --name=datamd --level=6 --raid-devices=4 /dev/md127
/dev/sda3 /dev/sdb3 missing missing
Here the output of the examine command after starting the old lenny:

All the rest I did with the installer:
The /dev/md125 is configured as /boot with ext3.
Then I created on /dev/md126 and /dev/md127 the crypted devices without
changing the parameters.
After the crypting devices are created (named md126_crypt and md127_crypt ?)
I've set up both for LVM
and created in md126_crypt the xenrootdg. md127_crypt I left alone for the
installation.
On xenrootdg I created an varvol for /var, homevol for /home, rootvol for / all
with ext3. I've used varfs, homefs
and rootfs for logical name of the filesystem. I created swapvol for swap use.
Here the graphical layout:
/boot ext3 bootfs on md125 with sda1|sd
