<pre wrap="">I actually found an email from a coleague who did a semi-walkthrough
with me on the setup.
I know the HowTos are great, but they are very technical.
I can read them but I find that they are hard to implement as they are
explaining the benefits, and suggest
that You should configure.. etc.. but no real steps and orders of what
to click.
So it feels like you are invited to this great party.. and you are
standing in front of this door,.. and you hear
the party going and everyone excited, but you can't open the door
because it has a combination lock.
We had some other issues with our server and actually returned it back
to the supplier and we are getting
a new server instead.
Since I have the old instructions of how I've done it last time, I'm
going to actually try and build a picture
by picture of screen shots of how I configured the RAID-1 (for the
dummies like me who need someone
to hold their hands).
Here is another thing:
With the LVM option, I never actually had any experience.
It would be great to play with it,. the only problem that I'm having is
that I'm never having the physical hardware
long enough to play with it and experiment with it.
But,. while I'm on that subject, I remember that when I did the RAID-1
option few months ago, I tried to test it
and see what happens if I pull one of the HDs out and try to connect
them one at a time to simulate a
HD's failure.
To my understanding, I was expecting to see both HDs (each in his turn)
boot up and no problem.
However, I found that only one of them was booting up correctly.
Was I missing something? (very likely).
Would I encounter something like that with the LVM?

You still need some means to boot if the failed drive is the one with
the bootsector on it. I have a boot floppy with grub on it, all set up
to boot from the mirror drive just in case. I have several copies, and
leave one part way into the floppy drive.
If you were creative and careful when you updated your boot loader, you
could probably just swap the failed boot drive with the mirror.

run mkbootdisk. It will make a syslinux boot disk with your current
boot kernel and initrd.<br>
Run the command by itself to get the syntax, but it is something like
this;<br>
mkbootdisk --device /dev/fd0 kernelname<br>
You get kernelname from uname -r<br>
