It will be a raid5 on 5 IDE disks using mdadm. I'm trying to create the array with 'mdadm --create /dev/md0 ...' and am getting an error: 'mdadm: error opening /dev/md0: No such file or directory'. There are no /dev/md* devices in /dev at the present time. I do have the md and raid5 kernel modules loaded. My question is: how do the /dev/md* files get created? Are they normal device file that are created with MAKEDEV?
It's odd that they aren't there - they are with Debian 3.0, and have remained there when I've upgraded a few test servers to testing/Sarge.
# cd /dev # ./MAKEDEV md
should do the business.
A useful trick I discovered yesterday: Add --auto to your mdadm commandline and it will create the device for you if it is missing :)
Well, it seems that this machine is using the udev scheme for managing device files. I didn't realize this as udev is new to me, but I probably should have mentioned the kernel version (2.6.8) I was using. So I need to research udev and how one causes devices to be created, etc.
Thanks for the help!!
