RAID controller: what a mess.

First of all I have to mention that I’m a newbie either in open SUSE than in Linux.

My problem is the following:

In the expert partitioner a lot of devices “appear” . Yast, I think, sees the two disk in mirroring i have and mount the previous installed windows XP either on the first than than on the second.
Summarizing:
Device | Size | F | Type | Mount


/dev/mapper/isw_cefgacbjhg_ARRAY_part2 | | DM RAID |windows/C


dev/sda1 | | sata1| |windows/D

dev/sdb1 | | sata2| |windows/E

I really don’t know because it seems to see two storage devices though they are in mirroring.

It can be usefull: i have a Intel RAID controller, and two disk in SATA of 500 Gb.

Finally I think there would be a mess with the raid controller. Do you have some suggestion?

Hi & Welcome!

Your observation is correct… As far as I know your SATA raid controller is not supported in the Linux kernel in Raid mode… This is due to the fact that the controller does not support a full hardware raid solution & the Linux kernel does not support this kind of BIOS/chipset emulated raid (also called ’ fake Raid’ ).
For more info check this page: Linux SATA RAID FAQ

If you have set up a raid1/mirror on your disks that’s currently holding your Windows setup, I’d advise to NOT install openSUSE (or other Linux distro). The Linux kernel does not see you raid (as the driver does not support this), so it will be discarded and break your raid (and your Windows install).

If you want to install openSUSE / Linux on that system you could use a separate disk, or first make a backup of the relevant Windows/data files and break the mirror. You could then choose to create a software raid.

It’s probably not the answer you where looking for… but I don’t know of a supported way around this (e.g. get the Intel sata raid working in mirror).

Hope that helps,
Wj

Hi Magic31

thanks for your suggestions. So for you it is better to break the mirror and install open SUSE with a software raid.
I have thwo other question:
1.I found in Novell site
Novell Adapter Lists
that the SUSE OS is compatible with my firmware chipset ICH8-ICH9 there are some patches for the kernel. It is possible for openSUSE?
2. If i do the installation breaking the mirror, the raid software of openSUSE would permit to mirror also the Win XP partion?
