Further to this, I have found: http://people.redhat.com/~heinzm/sw/dmraid/

I'm installed the RPM, and re-compiled the kernel after the patches
required (giving me 2.6.7-mm4) compiled dm-mod as a module. I've modprobed
dm-mod so I have:

[root@zeus md]# lsmod
Module                  Size  Used by
dm_mod                 59260  0
<trimmed rest of list>

when looking at dmraid however, I get:
[root@zeus md]# dmraid -r
Failed to find sysfs mount point
Carrying on with /dev/
No Software RAID disks

now, what /dev entries does this actually look for? I have a RAID0 set up
in the BIOS of the 'raid' card. Ideally, I'd like to rescue this so I
don't lose the data on the array.

Is this not supported yet? or have I missed something?

I am root. If you see me laughing, you'd better have a backup.
