DRBD is a distributed replicated block device that allows you to build high availability clusters. In this tutorial, we will be learning how to install DRBD on POP! OS Latest.
Before we begin, here are the prerequisites for this tutorial:
First, we need to install some packages required for DRBD. Open the terminal and run the following command:
sudo apt-get install drbd-utils kmod
Next, we need to download the DRBD source code. Go to the official DRBD website at http://drbd.linbit.com/ and download the source code for your version of Linux. After downloading, navigate to the folder where the source code is located and extract it.
tar -xzf drbd-<version>.tar.gz
cd drbd-<version>
Now, we need to compile and build DRBD. Run the following commands in the terminal:
./configure
make
sudo make install
Next, we need to configure DRBD. Create a configuration file at /etc/drbd.conf and add the following lines of code:
global {
usage-count no;
}
common {
protocol C;
}
resource <resource_name> {
device /dev/drbd0;
disk /dev/<partition>;
meta-disk internal;
syncer {
rate 1000M;
}
}
Replace <resource_name> with the name of your DRBD resource, and <partition> with the partition that you want to replicate. For more information about configuring DRBD, refer to the official documentation on the DRBD website.
Finally, we can start DRBD by running the following command in the terminal:
sudo modprobe drbd
At this point, you should be able to start DRBD with the drbdadm command. For example, to start the DRBD resource configured in Step 4, run the following command:
sudo drbdadm create-md <resource_name>
sudo drbdadm up <resource_name>
Congratulations, you have successfully installed DRBD on POP! OS Latest! You can now use DRBD to build high availability clusters.
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!
