How to make Raid0 on your dedicated server

Step 1

You install gdisk and mdamd packages using the command

apt-get yum etc install gdisk mdadm

Step 2

You copy the partition table using the tool gdisk:

sgdisk -R=/dev/sdX /dev/sdY
where the first disk X is the disk you copy onto and Y is the one you copy the partition from. So if you want to copy from sda disk onto sdb disk the command should look like this:
sgdisk -R=/dev/sdb /dev/sda

Step 3

You create raid using the following command (X is an appropriate disk partition)

mdadm --create /dev/md0 --verbose --level=0 --raid-devices=2 /dev/sdaX /dev/sdbX

Checking your partition layout you look for home partition, only here you can make raid0 or raid1.It's impossible to make raid from system partition.

Step 4

You format the newly made partition with mkfs, an example for ext4

mkfs.ext4 -m1 /dev/md0

Step 5

Now you have to mount partition raid0 in an appropriate place, so you check the ID of the newly made partition using the command:

Blkid

Next you copy the ID of your disk to /etc/fstab (in your case the place is /home)|

Step 6

You mount your disk.

If everything was done properly, after you restart your machine the disks should work as raid0
