Probably the LILO RPM missing on the CD. If you rebuild CD image with LILO RPM included, it might work.
if you can verify this, could you file this as an issue at http://bugs.centos.org/ - I'll make sure the situation is rectified in time for ServerCD 4.3
Has anyone looked at what SMEserver v7 (the Centos4 based one) does? It not only installs on raid by default, it creates a 'broken' RAID1 if you only have one drive so you can add a mirror painlessly later. I don't have a running system right now to see if they put /boot on raid1 or if they use lilo or grub.
Firstly, the primary aim of the CentOS distro is to stay in sync with upstream. So nothing on that is going to change.
Secondly, Feel free to evaluate what SMEserver are doing w.r.t installer and submit patches for the ServerCD.
Also, moving this conversation to the CentOS Developers mailing list, if anyone is interested in following this - subscribe there.

I have :-)

Yep - I've done Solaris installs like that for years and it really is nice to be able to add the mirror disk without backup/restore.

We use grub and have submitted some patches to RedHat for grub RAID install:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=160563
We've recently redone those patches inside anaconda et. al. and will push them up to RedHat soon.
As to disk layout:
/boot is RAID1 in all configurations / is RAID1 for one or two disks, RAID5 for 3-5 disks and RAID6 for 6+ disks

We submitted a patch for our "degraded RAID" install. Unfortunately, it was rejected by RedHat:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=189316
I might fight that battle again another day, maybe with a "Yes, I know what I am doing" flag.

Feel free to take whatever you need. It's all under mezzanine in SourceForge anonymous CVS (smeserver project) and patches are pushed upstream when we can.
Thanks,

And apologies for the confusion of reviving a very old thread - it sorted oddly in my mailbox and caught my attention. Anyway, I hope the information was useful.

FC5 grub does raid installation properly and therefore so will RHEL5 and Centos 5.

But can it do the 'install on raid with a missing mirror' so you can add it any time later? It would be a nice trick to match what you can do with windows server and this vmware appliance: http://www.vmware.com/vmtn/appliances/directory/316 which is raid-mirror a running physical machine to matching partitons under vmware via iscsi, then shut down the physical machine and boot up the vmware copy with minimal downtime.
