How to create persistent entries in /dev?

'evening all!

How does one create persistent (i.e. stay after reboots) entries in /dev? I need to manually make /dev/md1 and md2 using mknod in order to assemble two RAID arrays, but I'd like this to be automated.

I'm using Mandriva 2006.

Cheers!

Are you using devfs or udev? If using udev you can create a rule for them in /etc/udev/rules.d to be created when udev is started on boot, or when issuing /sbin/udevstart.

I'm using udev. There is a line in /etc/udev/rules.d/50-mdk.rules that goes:

KERNEL=="md[0-9]*", SYMLINK+="md/%n", GROUP="disk"

I'm assuming this means something on the lines of "create md0 to md9 in /dev"? But then why does it only create md0?

Do I need a NAME assignment in that line? I'm a n00b to all this stuff.

Cheers!

It would appear that the /dev/md? entries are created automatically if they are defined in /etc/mdadm.conf Or rather, it works now and that is the only difference that I made before rebooting.
