sudo apt-get install software-properties-common
```
This command installs the Software Properties Common package, which provides additional tools needed for adding third-party repositories.
Type the following command in the terminal:
```
sudo add-apt-repository ppa:linbit/linbit-drbd9-stack
```
This command adds the DRBD repository to your computer.
Update the package list by typing the following command in the terminal:
```
sudo apt-get update
```

Step 2 - Install DRBD Software

Once the DRBD repository is added to your computer, you can proceed to install the DRBD software. Follow these steps:

Type the following command in the terminal:
```
sudo apt-get install drbd-utils -y
```
This command installs the drbd-utils package, which contains the DRBD management utilities.
Type the following command in the terminal:
```
sudo apt-get install drbd-modules-dkms -y
```
This command installs the DKMS package required for building DRBD kernel modules.
Type the following command in the terminal:
```
sudo apt-get install drbd-dkms -y
```
This command installs the DRBD DKMS module, which is used to manage DRBD kernel modules.

Step 3 - Configure DRBD

Now that DRBD is installed on your computer, it's time to configure it. Follow these steps:

Create a new configuration file by typing the following command in the terminal:
```
sudo nano /etc/drbd.conf
```
This command opens a blank configuration file in the Nano text editor.

Add the following lines to the file:

global {
    usage-count no;
}

common {
    net {
        protocol C;
        max-buffers 2048;
        max-epoch-size 16384;
        sndbuf-size 0;
        timeout 30;
        connect-int 10;
        ping-int 10;
        ping-timeout 5;
        allow-two-primaries;
        after-sb-0pri discard-least-changes;
        after-sb-1pri consensus;
        after-sb-2pri call-pri-lost-after-sb;
    }
}

These lines configure the DRBD network settings.

Save and close the file by pressing CTRL + X on your keyboard, followed by Y and Enter.

Step 4 - Activate DRBD

The final step is to activate DRBD. Follow these steps:

Type the following command in the terminal:
```
sudo modprobe drbd
```
This command loads the DRBD kernel module.
Type the following command in the terminal:
```
sudo drbdadm create-md all
```
This command creates metadata on all DRBD devices.
Type the following command in the terminal:
```
sudo drbdadm up all
```
This command activates all DRBD devices.
Type the following command in the terminal to check the status of DRBD:
```
sudo drbdadm status
```
This command displays the status of DRBD.

Congratulations! You have successfully installed DRBD on MXLinux Latest. You can now use this powerful tool to create high-availability clusters and ensure the availability of your critical data.
