DRBD, or Distributed Replicated Block Device, is a tool for creating high-availability clusters by synchronizing storage devices between servers. It is an open-source project that maintains its code at http://drbd.linbit.com/.
This tutorial will guide you through the process of installing DRBD on MXLinux Latest. The steps are straightforward, and the whole process only takes a few minutes.
Before starting the installation of DRBD, ensure the following prerequisites are met:
The first step is to add the DRBD repository to your computer. To do so, follow these steps:
Launch the terminal by pressing CTRL + ALT + T on your keyboard.
Type the following command in the terminal:
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
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.
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.
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.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
