Setting up software RAID

Hello, All.

I've been working with RAID controllers for a few years (the PCI/SCSI
kind mainly), and that's been fun.

But now I want to try out software RAID. I know that Linux has some
built in RAID functionality, and that Windows 2000 server has some
sort of RAID 0 support. But I'm not sure at all about SW RAID in
general, so I could use some help getting started.


So, I'd like to ask your help and recommendations for me:

1) is there any RAID level that is best for SW RAID? What I mean is,
are there some levels that have efficiency problems?

2) I've only got a few drives to play around with really. So if I
build some software RAID setup, can I boot off of it?


Thank you very much.


Joe.

With current Linux: No.

With current Linux and RAID support statically in the kernel,
you can. If the boot partition is RAID-1, LILO is also able to boot
a Kernel with RAID in modules.

However my approach is a small boot partition (100MB) that contains
kernel image and lilo.conf and is mounted under /boot. I still
have RAID support statically in the kernel.
