I want to setup a RAID 5. I have 4 250GB drivers. One currently has SUSE 10.2 / Xen installed. I tried installing the RAID right off the bat, but it didn't work. The install always died. So I installed everything without the RAID configuration and it went great. Now I am ready to create the RAID 5 and would like some advise. I plan on using the RAID to store the VM files for Xen. I tried it with an LVM and without, both failed. Could it be that I need an updated NVIDIA driver?

I presume you mean software raid 5? First, although it is possible to get the root on raid, its a whole lot easier not to. That leave you with 3 drives. With raid 5 you will get n-1 worth of space, so you will get 2x250meg of raid 5 space. Now how are they cabled? You don't want any two of them on the same header. Performance will be degraded if you do. How much? Hard to say. Like every thing else in linux there is a great deal of hand wringing over this issue. But assuming you have at least 3 controllers on the machin you should be good to go. Lots of good howto articles on the web, many quite old.

mdadm, is it already installed on Suse. If not why not? It is sponsored by Novell and Suse :-) Assuming it isn't, is there way to add it to the package manager so I can use Yast to download and install it? Thanks for be patient with this windows guy trying to convert a Linux guy. John Andersen wrote:

mdadm, is it already installed on Suse. If not why not?
Well, which is it, installed or not? It is your system and not viewable from here, afaik.
It is sponsored by Novell and Suse :-)
You know this how? My rpm indicates: http://www.cse.unsw.edu.au/~neilb/source/mdadm/
Assuming it isn't, is there way to add it to the package manager so I can use Yast to download and install it?
Assuming it isn't, add the source to Yast and Yast will be able to download and install it.
Thanks for be patient with this windows guy trying to convert a Linux guy.
Would the windoz-guy please make an effor to post only relevant data in his posts, ie: not top posting above full quotes? (as per previous requests). -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org HOG # US1244711 Photo Album: http://wahoo.no-ip.org/gallery2 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Go into Yast, Software management, search button key in mdadm select, install and bob's your uncle.

Could it be that I need an updated NVIDIA driver? No, your nvidia graphics has nothing to do with it, and the chipset drivers (I assume you are talking about) are a part of the kernel. You can find out some info about them by modinfo <module name>, i.e. joe@jmorris:~> lsmod | grep nv sata_nv 30084 0
