Okay I will look into it, So far as I saw, i cant find the "mirror core" one..what kind of mirror cores are supported and what they will do? I googled for it but no docs for this.. I want to build a mirrorset on my nforce3 250GB raid ..so far when i use nosync the two disks get different when i copy something to the dm-mirror set..any cloues..should I use sync?
