Some motherboards claim to have RAID built-in but really it is software RAID in the BIOS.
OK, now I understand. I call it "pseudo-hw-raid". It still depends on software driver and cpu.
Linux's software RAID is usually better though.
I agree. And that is what I'm trying to use, linux software-raid built in kernel...
Firstly, is RAID support built-in to your kernel? Also did you set the partition types to "Linux raid autodetect" when running fdisk?
Yes, of course. All partitions are marked as "auto-detect" (fd), and raid support is in my kernel (not as module). As I wrote previously, all md's are autodetected without any problem: -------------------------------------------------------- md: Autodetecting RAID arrays. md: autorun... ... md: adding hdg1 md: adding hde1 md: created md0 md: bind<hde1> md: bind<hdg1> md: running: <hde1> <hdg1> raid1: raid set md0 active running 2 out of 2 mirrors md: ... autorun DONE <similar for all md's> --------------------------------------------------------- Richard Fish wrote: > Just an FYI, the md driver does not create sysfs entries and thus udev > does not create device nodes if autodetection is not performed by the > driver.

(md-support is in kernel, and partitions are marked as type "fd - Linux raid autodetect"). Concerning 2, I'm not sure if I understand correctly: Do you mean turning off initramfs support in kernel-configuration? Jarry -- [email protected] mailing list
