Installing SLES 11.1 on Intel Atom


I'm trying to install SLES 11.1 on an intel atom (intel D510M0 Motherboard).

During the install, SLES automatically configures two md containers, /dev/md127 (intel matrix storage manager container as far as I can tell), and /dev/md126 (6 drive raid 0 array).

I have only a single intel x25M in the system, however, so I'm not sure where its picking up the 6 drive raid 0 array from. Since /dev/sda is a part of md126, I cannot partition or install on /dev/sda, and obviously I can't install on the non fucntional raid array specified in /dev/md126.

I've attempted to remove /dev/md127 and /dev/md126 by using ctrl-alt-F2 to get into a shell and running mdadm --stop /dev/md127 and running mdadm --remove /dev/md127 (same procedure for md126). Unfortunatly as soon as I ctrl-alt-f7 toreturn to the GUI installer, the md devices return. I'm not sure what automated processes is creating the raid arrays, and there is no config file for md for me to edit that I can find on the system.

Any thoughts out there on what to do stop the creation of md126 and md127 or some how shut down the process that is readding them?

Thanks in advance.

Recommended : Prepare the partitions, before the Suse install.
Use e.g. the "Gparted Livecd", which also is the best choice for the
partitioning. You will need one partition " / " and a swap.
( And may be a " /home ".)


A) Installation Settings : Please click "Partitioning"
B) Choose : Custom partitioning.
C) Expert Partitioner :
Highlight the partition, you want to use, and click it.
C-1) Expert Partitioner : Hit the "Edit" button.
D) Tick : "Format Partition" ( And choose filesystem.)
... And tick : 'Mount partition/Mount point' and set " / ".

That's it. And you can hit "Finish", "Accept", etc.


E) Optional : Boot loader changes : Installation Settings > Booting.

Thanks for the reply knudfl.

I have tried using knoppix to boot and then using fdisk and mk2fs to create the partions on the disk. That works great, but when I boot off of the SLES 11.1 DVD, it creates md126 / 127 automatically and does not give me the option to directly access sda1, as sda1 is already a member of the raid set md126. I have also tried the boot option raid=noautodetect, but that has no effect on the creation of md126 / md127 either.

I'll see if I can grab some screen shots, but that can be a bit tricky given the fact that I'm installing the OS.

I'm also exploring using autoyast to just create the partitions via a autoyast xml file. That may allow me to bypass the auto creation of the raid array as well.

Nothing is created automatically, when you choose 'Custom partitioning'.

Please have a look at "image B" ( And all the others too ! )

From the SLES install screens (taken with a digital camera as it was simple).

As you can see, md126 is created automatically. I'm unable to delete md126, but I also cannot install to it as it is created as a 447GB raid set, but there is only one physical disk.

Screen shot with me unsuccessfully trying to delete the array.

Note that I can use ctrl-alt-F2 to switch to a shell to delete the raid set with mdadm, but it is recreated as soon as I use ctrol-alt-F7 to return to the GUI installer.

Yes, you have no partitions.

Create some beforehand, and please use the Gparted livecd for that.

Then you can choose, like shown in my screen shot C.

As I mentioned in post 4, I booted with Knoppix and used fdisk to create 4 partitions on the disk, and then used mk2fs to format the file systems. (See attached Screenshot).

Is gparted functinally different than using fdisk?
