rus,
This is critical
turn off the raid functions of your bios. You must do this or the fakeraid of the bios WILL interfere with md's ability to perform. Then try building the md raid.
William,
This might be a bit of a problem. The computer is quite old, and I had to get a raid card just to be able to connect sata drives to it. The bios boot order only lists the cdrom (I can't even get it to boot from floppy). The only way I can get it to boot off these hard drives is if I have them in some sort of raid set up through the card's bios (even concatenation works). Unfortunatelly, with concatenation, if 1 drive dies, I am forced to recreate the array, which kills things. I think I need to use the fakeraid driver. It keeps popping up anyway with weird error messages. For example, when there is no raid set up, I keep getting something like this:
Error adding sda to set silxxxxxxx: Raid type 234 is not supported. (This is from memory, so probably not exactly correct). I tried updating the bios, but I can't even seem to do that. It won't boot off the floppy, and when I boot of any dos based cdrom, I can't see the floppy. (I have external usb floppy. The internal one doesn't seem to work). Russ
Can you add each drive as a separate stripe? IE.. 4 drives, 4 arrays, 1 drive per array. I had to do that with an old promise card I used as a controller.
William,
Thanks for the suggestion. I actually though of the same thing this morning, and added the first drive to it's own (concatenated) array. That seemed to work and allow it to boot. I still can't get raid10 to work, but I'll start a new thread on that.

I don't think you will get raid 10 out of the anaconda installer. I don't think it is supported yet. So even if the raid 10 driver is in the installer's initrd, you probably will not get a raid 10 from anaconda.
