I did a Goggle search and found Linux Journal, Home, RAID-1, Part 1

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 :-)
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 appears I can use the method shown to make a /usr raid 1. I have
/usr backed up on my 9 GB USB device. But the author suggests you put
a copy of /usr on /var/. We will use mkraid which I find I do not
have. Perhaps I can yum it to my system. Perhaps there is a newer tool?
So like all writing it is dated and old just a couple of years
later. Instaed of using #init 1 so that /usr can be un-mounted, I
think using the rescue mode of the f7 dvd will be easier. Then f7 will
be off :-)
Karl,
I posted a message about converting a running Fedora 7 system from a
single disk to a RAID-1 system on June 30th, I listed out the steps I
followed. I did however use 2 identical disks. The subject of the
message was "RAID gotchas!"
