Creating /dev/md* device files

[Steve Witt <sawitt@electra.rsc.raytheon.com>]

I've just installed Debian 3.1 (sarge) on a new machine using the Debian 
Installer rc2. Among other things, it will have a raid5 software raid 
consisting of 5 disks. I'm at the point at which I'm trying to create the 
raid system but am having a problem with the /dev/md0 device file.

When I do the raid create: 'mdadm --create /dev/md0 ...', I get an error 
from mdadm:

mdadm: error opening /dev/md0: No such file or directory

I've got the md and raid5 kernel modules loaded. There weren't any 
/dev/md* files created during the install. I tried to create them using:

cd /dev; MAKEDEV -v md

The md devices were apparently created by MAKEDEV in terms of its output, 
but when I try to examine the /dev directory with 'ls', the files aren't 
there. Any clues as to how to proceed?

Thanks...
