Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Clean install of Gutsy Server, set up partitions manually for softwareRAID like so:
Drive 1: auto partitioned into 2 partitions, root and swap
drive 2: same as drive one
changed all 4 partitions to "use as physical volume for RAID"
disks 3 and 4: one partition, use for RAID.
set up RAID as RAID1, 3 different devices: 1 for root, 1 for swap(disks 1 and 2), 1 for home (on disks 3 and 4)
went back to partitioner, set raid device 1, which happened to be the home partition, to mount as /home
set raid device 2 to mount as /
set raid device 3 to mount as swap
wrote changes to disk, finished installation, and got the "GRUB hard disk error"
I know from googling that this means grub can't map the disk geometry, which isn't very suprising.
Booted into knoppix and both RAID devices are there, and root has all the stuff in it it's supposed to have.
Did i do something wrong? possibly RAIDing the swap is wrong? What do i do next?
looks great, thanks. I got ubuntu to load by unplugging the second hd in the array. Now, trying to edit the grub configuration, typing "device (hd0) /dev/sda" as well as sdb gives "Error 15: file not found"
md1 : active raid1 sdb1 sdc1(S)
x blocks [1/1] [U]
md3 : active raid1 sda5
x blocks [1/1] [U]
md2 : active raid1 sda1
x blocks [1/1] [U]
for md2 and md3 the other hard drive is disconnected. Now that i'm looking at that that doesn't look quite right?
anyway, i took a quick glance at your guides last night but wasn't certain what i was looking for. I'll give it another go.
Thanks for your help!
So i went ahead and reinstalled, this time leaving /boot and swap out of the raid. No luck, i get the same error.
As part of the process of cutting out variables i removed that last drive, so now device.map looks like:
I've tried many different things trying to get this to work, maybe it's time to try a completely different approach. What i'm thinking is i could just get a small drive for the OS and back it up manually, then have the rest with all the data on them RAIDed. Are there any packages that just allow you to copy an entire hard drive to another drive?
