I did a Goggle search and found Linux Journal, Home, RAID-1,
Part 1 and 2 by Joe Malmin and Ron Shaker, 2002-08-13 and I have
read it like a book once. It talks to the raid-1 being a superior
way to back up your computer. I learned that raid mirrors
partitions not hard drives. You can use any two hard drives or even
the same hard drive! I plan to make a raid 1 using the two hard
drives I have in this computer right now :-)
But note that RAID is not a substitute for backup. It does not let you
recover an older version of a modified file, nor a file deleted by
accident. You need backups even if you setup RAID 1.
One is a 30 GB and this is a 160 GB but f7 is in a partition of
12 GB. So I can make a 12 GB partition on the 30 GB HD and make a
raid 1 system between /dev/hda2 and /dev/hdb5.
The book says if /proc/mdstat exists, you have raid support in
your kernel. I do :-)
The book set up raid 1 on Red Hat 7 and Debian Potato with the
early kernels 8-)
It seems the tools you've read about are a bit outdated. Research a
bit about LVM before you setup RAID in your machine.

Well it appears LVM is about as obscure as raid-1 :-) I am not
sure all this will work out for me. The whole thing is odd. I can see
how to make the partitions fd type with fdisk but it is very mushy about
what this might do.
