MINI-HOWTO: Installing OpenBSD 3.3 on a Soft-RAID Array

As this is a MINI-HOWTO, explanations are not given and I make a lot of assumptions about your knowledge of the different software used herein and where you can receive more and more accurate information of what I’m showing here. I won’t take any responsibility on what can go wrong on using the information given here. It’s for sure not foolproof, but seems to work fine for me. You’ve been warned in any case.

[Edited, as it was cluttering the space here. You’ll find the document here ]

This howto is quite good! Though, I found a little bug :)

In raid0.conf.new it shouldn't be
=============
START disks
/dev/sd0a
/dev/sd1a
=============
but
=============
START disks
/dev/sd0d
/dev/sd1d
=============

And what's the point of creating a second swap partition?

The first swap partition one is used by the minimal installation and primarily to get rid of an error message which I didn't like (that's also why I made it just 32MB).

The second swap partition is on the RAID and is the "real" one. That is, if one harddisk fails it should swap to the other. If we didn't put the swap onto the RAID, there would be a good chance that things would really break in case of a failure.
