Mandrake 10.1 not creating /dev/md1


Hi, I decided it was time to move up from Mdk9.2 to Mdk10.1(official). But I've hit a few snags with my software raid0 devices.

To get my software raid setup like it was on the old install I added the raidtools package with "urpmi raidtools" and copied my old "/etc/raidtab" to the new system.

But one of my two raid0 devices does not load at boat, saying that "/dev/md1 dosn't exist". While the other (md0) loads ok.

if I manualy create and active the device with:
Code:
mknod /dev/md1 b 9 1
raidstart /dev/md1
it will start fine and I can then mount it, just like md0


I think it is a result of mdk10.1 using "udev" to dynamicly load the device nodes. I read that I should be abel to put a copy of my nod in "/etc/udec/devices/" and that this would be automaticly copied to /dev/ on boot, but this does not seam to happen.

Question: How do I make sure udev adds the correct device node?

And while mentioning "udev":
udev has caused me a lot of headace on my other machines, symbolic link pointing to my mouse device disapearing (making something like "ln -s /dev/input/mice1 /dev/mouse" useless) and making my /dev/nvidia* devices disapear... althou for those two problems I found workarounds (pointing to the correct device instead of the symlink, and adding nvidia to modules.preload)

(Please ask if aditional system information is neaded, I'm not sure what is relevant to know in this case)

Since I nead to get on with life I made a temporary fix.
Added the following commands to the end of rc.local so that the raid is brought into action "manualy".

mknod /dev/md1 b 9 1
startraid /dev/md1
mount /dev/md1 /mnt/Storage1

But I would still be happy to find a proper way of doing this, maybe I nead to change the way the raid0 module is loaded to the kernel, or make it so it's not a module?

I've installed Mdk1 10.1 on 3 of my comps now and I love it Realt the best distribution version I've seen!
