live cd can not see raid array
Posts: 959
I am trying to get mepis to install on a system with 2 x 320Gb hard disks set up in a raid0 (striping) array, but mepis can't seem to see any hard drives at all. I was using the 6.5 beta5 cd at the time
Has anybody else had any success with this or is there any way to get mepis to install onto a system with any type of raid array?

I'll give it a go.
for the time being, the machine has a raid0 striped array that was built using the bios and a fresh install of XP media centre, (it's not my machine, I would never subject a system to such abuse as installing windows) but I took a snapshot of it using my acronis 10 boot cd, which I believe is capable of dropping the data onto any type of disk layout and dynamically resize the image to fit the disk or partition, provided windows really unbelievably stupid and painful hal, sid (nothing to do with Debian) and wga don't think I'm trying to pirate it.
I am having 2nd thoughts about using raid0 because the overall reliability is exactly half that of independent drives or JBOD. I have also had a brief look at LVM, but I don't understand it enough yet.
When I went to install mepis, it couldn't find a hard disk at all. It's on an Asus M2NPV-MX with a dual core Athlon 4200, 2Gb RAM and 256Mb Nvidia GT7600 in a full alloy Lian Li case, a really nice system apart from the ugly OS, which we only allowed to use 32Gb of the available 640Gb.

What kind of array? if it is

What kind of array? if it is a fake array, the live CD cannot see it since you need to load some drivers with initRD. Hardware array ought to be transparent to the OS.
I wrote a wiki entry a while ago (for MEPIS 3.4.3, but probably most of it is still valid). See here: http://www.mepis.org/docs/en/index.php/Fakeraid_mirror
Basically, you need to install and then mount the raid... Good luck...
