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.

Thanks,

Gordon

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