Hmm. Not sure if doing that is efficient though. That's kind of like... Uhm... Patting your head with one hand while rubbing your stomach with the other (for lack of any better analogies). Lots of IO for little data.

With software raid you can use different raid levels for each partition, something that cannot be done with hardware raid. In this real example, the /boot partiition has been assigned to raid 1 and the remaining partitions to raid 0.

It's linux magic!

thats not a raid.
that are just some partitions, packed into a software nightmare.
real raids consists of whole disks.

Wondering if there is any merit in having two /boot partitions (one on each physical drive) and setting it up as raid1 instead of raid0 and all the rest as raid0?

Oky finaly a easy way to install your harddrive(s) via linux

You will need to do a reinstall (i will add screen shots asap)

Oky goto OVH manager, servers, Reinstall / Change OS

When you get to "Choice of the partitions" goto "Other layout of partitions" and pick "RAID software"

You can leave everything till you see "Mountpoint" pick "boot" and say give it 500meg (or wotever you want)

NOW when u see "RAID type :" you pick 0 and thats its you can use both your harddrives.

Wow yay!!!

I will edit this later with screenshots and stuff

Hope it helps some of you
