Combining SATA drives

Hi there,

I'm currently trying to add two (empty) SATA drive together so I have 1 big drive. I thought that doing this with a software RAID-0 / linear configuration would be the easiest way. wong!(?)

I found several tutorials but with all I get stuck.

I did so far:

mdadm --create --verbose /dev/md0 --level=linear --raid-devices=2 /dev/sda1 /dev/sdb1

> mdadm: error opening /dev/md0: No such file or irectory

Then I tried:

mknod /dev/md0 b 9 0
mkraid /dev/md0
> cannot determine md version: 6.

And now I'm out of idea's

Does anyone have any suggestions?

Thanks in advance!!

Both of those things happened to me. The problem is that your BIOS is fiddling with your choice of brand names of your SATA drives.

When I performed the little procedure that was originally written, I couldn't keep superblocks present in my SATA partitions.

But let me ask this first: If you follow the RAID install on Slackware 10.2 instructions (not my follow on instructions), can you get a RAID partition to EXIST, even if it goes away the next time you reboot?

After a lot of googling I finally discovered that I left out some features during the kernel compilation... sigh!

Anyway I finally got it working! Your instructions were very helpfull with that, thanks!

Also thanks for finding time to help me out! I'm quite new and help is therefore very much appreciated!

Now i'm onto the next mission, getting my SATA RAID config to sleep (with hdparm). But I think I'll start a new topic for that. I haven't found any topics with a simular problem yet.
