Thank you for your reply.
Does that kickstart effectly produces a partitioning that is exactly the same on both disks? Because that is the problem I'm facing: the partitioning produced by the kickstart is different on the two drives.
Yup, both disks are identical layout.
Also, why did you put /boot and swap in raid? Was it for obtaining identical partitioning on both drives? For swap, the kernel already does performance optimization when swap partitions are on different drives, and /boot.. I always tended to keep /boot be as simple as possible, to avoid any problem during boot.. but maybe, these days with initramdisk there's no more need for that..

Keeping the drives identical is a big part of it. Even on my 3+ disk RAID level 5 systems, I make /boot a RAID 1 mirrored across all drives as /boot can not be RAID5.
I mirror /boot and <swap> because if either is lost, the system dies. :) Imagine if something was in swap, then swap vanished, and then the system tried to retrieve what was in swap... Not so good. :P
The biggest concern is that, on /boot, you need to ensure that grub has been setup on all drive's MBR. The grub shell allows you to ensure that.
Thank you for the explanation. Now I have a good reason for swap to be in raid1.
