Deploying LINSTOR by Using a Juju Charm for Production-Ready Kubernetes Storage

This blog is a walk-through tutorial on how to deploy LINSTOR®, by using a LINBIT® authored Juju charm, into a MicroK8s environment. You can use LINSTOR as a full-featured and production-ready replacement for MicroK8s’s “hostpath” storage. Defining Terms LINSTOR is an open source software-defined storage (SDS) management solution developed by LINBIT. LINBIT also develops DRBD®, […]

Creating Persistent Storage for Kubernetes by Integrating LINBIT SDS Tech Guide

LINBIT® SDS is the product name for LINBIT’s LINSTOR® software, and the plug-ins and drivers that work with it to give you the tools to create software-defined storage solutions for your high-availability and disaster recovery problems. You can use LINSTOR independently to control DRBD® and other block storage devices native to Linux, without a cloud-based […]

Software-Defined Storage Solves High-Availability & Disaster Recovery Problems

Software-defined storage (SDS) is a technology used in data storage management that intentionally divides storage duties of software and hardware1. Software is responsible for: Provisioning capacity Protecting data Controlling data placement Physical hardware is where the actual data (the 0s and 1s) is2 stored. SDS allows the storage hardware to be replaced, updated, and extended without […]

Implement Fencing Within a Pacemaker-Managed Cluster Using DRBD 9’s Quorum Feature

Implementing fencing properly is a way to ensure the consistency of your replicated data by avoiding “split-brain” scenarios. When communication between cluster nodes breaks, fencing prevents the data from diverging among your replicas. DRBD® and Pacemaker each have their own implementations of fencing. To be clear, this article only talks about how to achieve fencing […]

Using Velero & LINSTOR to Back Up & Restore a Kubernetes Deployment

This article will describe how you can use LINSTOR® and Velero to back up and restore a Kubernetes deployment, including persistent storage volume data, to and from a remote AWS S3 bucket. This post builds on a solution described in an earlier article, Backing Up Your Kubernetes Deployments With Velero & LINSTOR. You may want to […]
