Does anyone know how ataraid actually works? If you are using ataraid and you can see you fs that are mounted using df -k /dev/ataraid/d0p6 /dev/ataraid/d0p1 /dev/ataraid/d0p2 /dev/ataraid/d0p3 /dev/ataraid/d0p4 Then I would assume that ataraid is working correctly with my Promise Fastrak 100 lite controller. What happens suppose to happen if one of your disks fails in your mirrored array? Does ataraid automatically rebuild the failed drive? Does ataraid make sure that the drives are in sync? Any help clarifying how ataraid actually works and what it suppose to do would be a great help Thanks. Gary
