installing slackware on a software RAID1
Hello everyone!
i'm searching for a guide to install slackware 13.1 64bit directly on a couple of disks that will be mirrored at install time. but can't find anything.

1) Is it doable?
if yes:
2) do I need to set some small /boot non-raided partition (as seen here ?
or since its just mirrored I can avoid it? Do I need a ramdisk (and does such a ramdisk exist on the slack DVD) or can I use mdadm to create the raid1 just before I run setup ? as seen here

if not:
3) can I use this ancient guide to create the raid1 after i install slackware on a single disk?

Thank you for your help!

Have you read the README_RAID.TXT which is on the Slackware disks or in the top level directory if you are downloading 13.1?

I did this a few months back. It was pretty easy. I seem to recall that I installed my box using a USB key (using AlienBOB's USB script), and then I saved all the setup scripts for the devices and raid levels. I did it a few times until I was totally happy. One mistake I made was trying to setup root (/) on a raid5 set - you can't do that - but it wasn't obvious at the time. This was why I ended up doing it a few times.

It is definitely possible to have the root partition on raid5. See the README I referred to in my previous post. You do however have to have a /boot partition which isn't raid5 and get the initrd right.

Ah yes - I remember now. Although it was / that gave me the problem because I did not use a separate /boot, rather putting it inside /.
