OK, so I've got three image files in /home/, and they each reside on different physical drives:

image1.img



image2.img



image3.img

Each image is the same size, and I want to put the images themselves into RAID0.

How should I go about RAIDing them?

EDIT: Using mdadm I get this error:

EDIT: Output of cat /proc/mdstat

EDIT: Output of sudo gparted /dev/md0

To install the Linux software RAID you need to install the mdadm package.

sudo apt-get install mdadm

If you want to make a software RAID-0 from the three image files, you need to create loop devices for each image files:

sudo losetup /dev/loop1 image1.img

sudo losetup /dev/loop2 image2.img

sudo losetup /dev/loop3 image3.img

After you can create a RAID-0 array from them:

sudo mdadm --create /dev/md0 --level=0 --raid-devices=3 /dev/loop1 /dev/loop2 /dev/loop3
