Re: [CentOS] Installing from a custom kernel

I believe anaconda only supports installation on raid0 and raid1.

What you can do in your setup, since it is only a 4 disk setup is:

create 4 128MB raid partitions at the start of each drive for a /dev/md0 raid1 with 2 spares, create an ext3 fs for /boot on it

create 4 raid partitions of the remaining spaces, create a /dev/md1 with 2 drives, and a /dev/md2 with 2 drives.

make /dev/md1 and /dev/md2 lvm volumes

create a volume group of /dev/md1 and /dev/md2, say called CentOS,

create a 'root' logical volume of say 16G with an interleave of 2, create a 'swap' logical volume of say 4G with an interleave of 2

One problem. /boot must be on its own unless grub in RHEL5/Centos 5 has lvm support. /boot needs to be on its own raid1 array.
