Hi!
Hm, you were root while trying to MAKEDEV, weren't you?
If there still is nothing listed in 'ls /dev/md*', you could create them
by hand, as many as you need:
root@host:/# mknod /dev/md0 b 9 0
root@host:/# mknod /dev/md1 b 9 1
[...]
(creating /dev/md0 as a 'B'lock device with major device number 9
and minor 0)
Oh, and don't forget to assign proper access permissions... I'd suggest
root@host:/# chown root:disk /dev/md*
root@host:/# chmod 0660 /dev/md*
If the problem persists after the devices are present, please report
back - but "no such file or directory" usually indicates that the
device node is missing, not the underlying driver. :-)
