I've just installed SUSE 10.2, using RAID 5, on an IBM Netfinity x232 server. I created one small partition for /boot, a RAID array over 4 disks for / and a 2nd RAID for swap. I assume I could replicate the /boot partition across all 4 drives and add them to GRUB. I think you should. Not only /boot, but also the MBR part of grub, so that you can boot from any of the four disks. I'm not sure exactly of the best manner to do this; IMHO, the best and easiest way is through the grub command line, i.e grub
grub> root (hd0,1) grub> setup (hd0) grub> root (hd1,1) grub> setup (hd1) ...etc, then grub> quit hd0,1 corresponds to first hd, second partition (assuming swap is the first partition, adjust as needed. Then add corresponding entries in menu.lst, and add a fallback #, with #= the menu entry of the second disk, etc. Do a search for RAID+GRUB for a step by step set of instructions. HTH.
I asked my boss if it would be worth adding a few hundred Euros in cost to get hot-plug and hardware raid where the only action neccessary for a disk replacement would be to stand in front of the server and simply plug in the replacement for the broken server. That way my stand-in would only need to know that the disk is broken and how to push the button to pop out the disk and then plug in the new disk. He immediately saw the light and signed the order for the server with hardware raid and hot-plug disks. I have little experience with software raid, but these steps don't entice me very much to start playing around with it. Compared to the costs of a standing server and the risk of a mistyped command on the command line when your blood pressure is already elevated due to the alert situation I am not convinced it is worth the hassle. It might be different for a server or workstation at home where cost is the most important factor. -- Sandy List replies only please!
