Tim,
>From what I remember it's best to set it up when you installing the
system, then you can install the bootloader to /boot in RAID 1.

is what I followed.
Thanks,

I've used Debian Linux for a number of years but up until now always with a
single hard drive.
I want to build a new system that will have a pair of 1TB drives configured
as a RAID-1 mirror. In reading the mdadm Wiki the discussion begins with
installing mdadm.
My goal is to have a system where if either drive fails things will a)
continue to run from a single drive, and b) be able to replace the failed
drive with a new one of the same size and have the system rebuild into a
mirrored array again.
It is not clear to me how I need to begin the installation sequence.
My question: Do I install Debian to a single drive and will installing mdadm
then allow me to add the second disk and setup RAID? Do I need to configure
each drive in some way before installing Debian and then mdadm?
If there is an up-to-date "how to" that describes this please just point me
there. I have not found anything that seems to start at the point where I
just have bare metal.
