DRBD (Distributed Replicated Block Device) is an open-source software that allows two or more servers to share a block device over a network. In this tutorial, we will explain how to install DRBD on FreeBSD latest version.
Before proceeding with this tutorial, make sure you have a FreeBSD server up and running with root access.
First, we need to install the required packages for DRBD. Run the following command to install them:
pkg install kmod-drbd-latest
Once the installation is completed, we need to configure DRBD. Edit the /boot/loader.conf file and add the following line at the end of the file:
drbd_load="YES"
Next, create a new DRBD configuration file at /usr/local/etc/drbd.conf with the following content:
global {
usage-count no;
# other global options here
}
common {
protocol C;
# other common options here
}
resource example {
# set the devices you want to use here, and any options for them.
# for example:
device /dev/drbd0;
disk /dev/ada0s1;
meta-disk internal;
on server1 {
address 192.168.0.1:7788;
node-id 0;
}
on server2 {
address 192.168.0.2:7788;
node-id 1;
}
}
Make sure to replace "example" with the desired resource name, "/dev/drbd0" with the desired block device, and "/dev/ada0s1" with the desired device to mirror.
Now, start DRBD service with the following command:
service drbd onestart
This will start the DRBD service and setup the block device for mirroring.
Use the following command to verify the DRBD status:
drbdadm status
This will show you the status of the DRBD service for each node.
In this tutorial, we explained how to install and configure DRBD on FreeBSD latest version. DRBD is a powerful tool that can help you share and replicate data between servers, improving data availability and reliability.
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!
