But this means imbalanced IO. An inbalanced IO, from my application perspective is a disaster. I am wondering whether zone number greater than 1 may be an option in mdadm. I will most thankful for your opinion on this matter. PS I managed to expand raid0 ( very very experimental , and only with zone nr == 1). I still have to learn how to write the superblocks though because I cannot re-assemble the raid, and behave according to md rules.
