DRBD stands for Distributed Replicated Block Device, which is a Linux-based software that facilitates data replication between two storage devices over a network. In this tutorial, we will learn how to install DRBD on OpenBSD.
Before installing DRBD, make sure you have the following prerequisites in place:
Follow the below steps to install DRBD on OpenBSD:
The first step is to install the required packages. Open the terminal and run the following command:
$ sudo pkg_add drbd
This command will install the DRBD package on your OpenBSD machine.
The next step is to create a DRBD configuration file. Open the terminal and run the following command:
$ sudo vi /etc/drbd.conf
This command will open the configuration file in vi editor. Add the following lines to the file:
global {
usage-count no;
}
common {
protocol C;
}
resource r0 {
device /dev/drbd0;
disk /dev/sda1;
meta-disk internal;
on node1 {
address 10.0.0.1:7788;
node-id 0;
}
on node2 {
address 10.0.0.2:7788;
node-id 1;
}
}
The next step is to start the DRBD service. Open the terminal and run the following command:
$ sudo /etc/rc.d/drbd start
This command will start the DRBD service on your OpenBSD machine.
The final step is to verify the DRBD installation. Open the terminal on both nodes and run the following command:
$ sudo cat /proc/drbd
This command will display the current status of DRBD installation on both nodes.
Congratulations! You have successfully installed DRBD on OpenBSD. Now, you are ready to replicate data between two storage devices over a network.
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!
