Hello there!

I don't want to force anybody to make it on behalf of me but trust me: i've looked hundreds of sites and i can't find a good starting point for this.

I have 4x500Gb HDD's which i want to set up in RAID 10. The most promising description is here, but it's a little old and unclear for me, above all i prefer Debian over Ubuntu (i know there are slight or no differences).

Is it possible to build RAID 10 with Debian's installer or i need to build RAID 1 first in the installer then use mdadm later?

What is the best practice for building software RAID 10 under Linux (Debian)?

Thanks for your time, fabrik
