fake-raid-1 не зеркалирует

В общем. Поставил рейд-контроллер за 20 баксов. Включил в его биосе RAID1. Поставил dmraid. Создаю партишн на /dev/mapper/sil_aibgdccdcffh. Все создается как /dev/mapper/sil_aibgdccdcffh1. Гляжу на /dev/sda - есть партишн, а на /dev/sdb - ничего нет, хотя он включен в массив. Причем сам dmraid запускается с ошибкой. Выходит, что в рейде учавствует только один диск. А куда же мог деться второй?
