I've got an old box that I don't want to scrap yet because it's got a nice working 5-disk RAID assembly. I want to create 2 arrays: RAID 1 with 2 disks and RAID 5 with the other 3 disks.

The RAID card is Intel SRCU31L. I can create the RAID 1 volume in the console that you access with Ctrl+C at startup. But it only allows for creation of one volume so I can't do anything with the 3 remaining disks.

I installed Debian Lenny on the RAID 1 volume and it worked out nicely. What utilites could I now use to create/manage the RAID volumes in Debian Linux? I installed the raidutils package but get an error when trying to fetch a list: #raidutil -L controller or #raidutil -L physical

# raidutil -L controller
osdOpenEngine  : 11/08/110-18:16:08  Fatal error, no active controller device files found.
Engine connect failed: Open

What could I try to get this thing working? Can you suggest any other tools?

Command #lspci -vv gives me this about the controller:

Forget about the raid card and LVM the disks.. Its much nicer to manage..

Is just my opinion, though find some tools on the intel site?? In my past ive found, Debian is notorious for not supporting RAID cards.. (one of the reasons i moved to Centos actually) :D

It's an old card - I did search Intel's site and the posts there were from 2001 and mentioned Red Hat 7.1 :) But could you please elaborate on LVM? I don't have any experience with it - where to start? What should I install etc –  Siim K Nov 8 '10 at 21:04
    
Well you dont need Redhat or Centos to use LVM.. I suggest you look on howtoforge.com I believe there you will find references on how to setup an LVM.. Debian/Ubuntu is fine Basicaly LVM Logical Volume Manager is a way to easily manage your disks ( you can do lots of things, im sure you want to do ) :D –  Arenstar Nov 8 '10 at 21:42
    
LVM provides some benefits, but not the data security of RAID. –  Drew Stephens Nov 9 '10 at 23:11

Linux has several implementation of how RAID can be done:

  • Pure HW RAID - controller driver required for management, not always for use, this is what you need
  • dmraid - manages software RAID, arrays created by some HW RAID controllers or by non-true, so called BIOS-RAID, maybe this will work for you
  • mdraid - pure Linux native software RAID, very fast, easy, safe, active, not related to HW RAID

I see that Intel has it's own linux utility to manage this RAID controller. Probably you will need some old libraries for compatibility and I hope new kernel has same abilities for these utilities to recognize device.

Good luck

LVM has nothing to do with RAID!!!
