Hi ataraid and md raid cannot mixed because in case of unsynchronized data, ataraid (and also promise raid) will fail. However, if you take great care, you can use ataraid for some partitions and md raid for other partitions. Make sure that any programs running on md raid partition DO NOT call /dev/hdeN but instead /dev/ataraid/d0pN I recommend using atleast /boot and / for ataraid if you choose to Mix ataraid and md raid. It is important not to access disk partitions by their direct names (eg /dev/hdeN) ALSO not access by the disk labels when the partition participates in ataraid Because /boot (/ if you dont have /boot) must be either non-raid partition or raid 1, if you decide to use software raid, you can use ataraid for /boot or /. I didnt test it but ataraid (raid 0 or raid 1) on boot partition will work On Sat, 18 Jan 2003, Marcin wrote: > Hi, > I've got Gigabyte GA-7ZXR motherboard with Promise 20265 FastTrack Lite raid > controller.
