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.
Regards,
Tim
