I guess I'm not the only one who is trying to be an a**hole :) Ask md-raid developer [1] because he states about the bug there (and also somewhere else) Go find bug number yourself. If you have any counter-information, share it here, correct me and let us all learn. For all others, %60-70 of raid10 configurations may fail one drive with current raid10 module shipped with CentOS5 because of being somehow old. Thanks...
