Kubernetes is an open source container orchestration system. It allows you to create, update, and scale containers without worrying about downtime. In this tutorial, you will deploy a PHP 7 application on a Kubernetes...

Linux's mdadm utility can be used to turn a group of underlying storage devices into different types of RAID arrays. This provides various advantages depending on which RAID level is used. This guide will cover how ...

Whether you’re adding more space for data or evaluating ways to optimize database performance, this tutorial will guide you through relocating MySQL’s data directory.

Whether you’re adding more space, evaluating ways to optimize performance, or looking to take advantage of other storage features, this tutorial will guide you through relocating PostgreSQL’s data directory.

Flexible and scalable data storage is a baseline requirement for most applications and services being developed today. With today's complex deployments, containers, and ephemeral infrastructure, the days of simply sav...

In this guide, we’ll show you how to move an Apache document root to a new location which allows you to independently scale storage for different sites.

In this guide, we discuss how to use Linux's mdadm utility to manage RAID arrays and perform day-to-day administrative tasks. We cover how to start, stop, or remove RAID arrays, how to find information about both the...

The mdadm utility can be used to create and manage storage arrays using Linux's software RAID capabilities. Administrators have great flexibility in coordinating their individual storage devices and creating logical s...

A Linux container is a grouping of processes that is isolated from the rest of the system through the use of Linux kernel security features, such as namespaces and control groups. LXD lets you create and manage these ...

Databases grow over time, sometimes outgrowing the space on the file system. You can also run into I/O contention when they’re located on the same partition as the rest of the operating system. RAID, network block sto...

Velero is a convenient backup tool for Kubernetes clusters that compresses and backs up Kubernetes objects to object storage. It also takes snapshots of your cluster’s Persistent Volumes using your cloud provider’s bl...

On Ubuntu, by default, the Nginx web server stores its documents in /var/www/html, which is typically located on the root filesystem with rest of the operating system. Sometimes, though, it’s helpful to move the docum...
