How To Install vdo on CentOS 8

vdo is Management tools for Virtual Data Optimizer

Introduction

In this tutorial we learn how to install vdo on CentOS 8.

What is `vdo`

Virtual Data Optimizer (VDO) is a device mapper target that delivers block-level deduplication, compression, and thin provisioning. This package provides the user-space management tools for VDO.

We can use yum or dnf to install vdo on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install vdo.

Install vdo on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:
