Using Robot (RAID1)

The simplest and quickest way is to reinstall the operating system in the "Linux" section of the Robot control panel.
You need to navigate to this section, review the information, and then select the appropriate OS from the available images. Check the box agreeing that all your data on the dedicated server's storage will be erased.

After clicking the "Activate Linux installation" button, you'll receive a message similar to this one:

Don't forget to copy the password generated for you, which will be assigned to the root user upon completion of the OS installation.

Next, to start the reboot process of your server, use the "reboot" command if you have an active SSH connection or use the "Execute an automatic hardware reset" button in the "Reset" section of the Robot control panel.
Wait a few minutes, then try connecting to the server.

You will see the selected OS installed on the clean storage. By default, you will have the system set up with RAID1.

Using installimage (RAID 1/0/10, etc.)

The installimage utility is a special tool for semi-automatic OS installation, providing basic settings such as RAID type, network configuration, disk partitioning, etc.
To begin, you need to switch your dedicated server to SystemRescue mode. You can find instructions on how to do this in the corresponding guide.

Make sure to save the password for accessing the created Rescue session since this password will be assigned to the user of your system after the installation.
After activating the Rescue utility, connect to your server.

Great. Now enter the following command:

installimage

You'll almost instantly get the software prepared.

In the list that opens, choose the Linux distribution or a custom installation image you want to install. Let's take Ubuntu as an example.
Navigation in this window can be done with the arrow keys on your keyboard or by double-clicking with the left mouse button (LMB).
Next, select the desired version of this distribution from the available options. For example, let's choose the latest available image — Ubuntu 22.04.

Review the information and press Enter.

A window with the system configuration opens before you.

First, pay attention to the SWRAID and SWRAIDLEVEL parameters.

SWRAID enables or disables Software RAID operation (leave the value as 1 for active).
SWRAIDLEVEL determines the level of RAID to be installed. By default, it is set to 1, which means RAID1 will be installed. If you want to install a different RAID level available for your hardware, specify the number according to the RAID type. For example, for RAID0, this parameter should look like this:

SWRAIDLEVEL 0

After configuring all the necessary parameters, press the F10 key on your keyboard to save the modified configuration.

Confirm the information that all existing data will be deleted from your storage.

The OS installation process starts according to the specified parameters. Wait for it to complete.

Once the installation is finished, you will see a message like this:

Reboot the server using the "reboot" command or the Robot control panel.

After a few minutes, connect and observe the OS you selected has been reinstalled. Since we specified RAID0 in the example configuration, your storage is now set up accordingly.
