Open Source VMware Alternatives That Can Integrate With LINBIT Storage Solutions
This article contains content contributions from LINBIT® team members: solutions architects Matt Kereczman and Joel Zhou, CEO Philipp Reisner, and developer Moritz Wanzenböck. If the Broadcom VMware acquisition negatively impacts you, you might be looking around for possible VMware alternatives, especially if you have customers who are also affected. Or maybe you have not been […]
Comparing Open Source Virtualization Platforms
More and more, businesses and companies are seeking to repatriate services and infrastructure from the cloud to on-premise or hybrid solutions. This might be for a variety of reasons. Whether repatriating is for cost savings, performance, security, control, or other reasons, it is happening. Increasingly, companies are turning to open source solutions when repatriating services […]
LINSTOR Operator 2.10.6 Released with LINSTOR & DRBD Updates
LINSTOR Operator 2.10.6 is the latest release of our Kubernetes Operator. There are two primary reasons for this patch release: we have updated LINSTOR and DRBD to their latest version, and we have updated LINSTOR CSI. LINSTOR and DRBD have been updated to address an issue affecting thinly allocated volumes that might cause incomplete resyncs […]
Red Hat’s OpenShift 4.22 is Here
First, I want to mention that Red Hat released OpenShift 4.22. This relates to LINBIT because with this release, Red Hat made the Two-Node OpenShift with Fencing (TNF) feature generally available. And this TNF can leverage LINBIT SDS for shared-nothing clustering. This release is of interest to organizations that run such small clusters, in many locations, […]
Getting Started with the LINBIT Deployment Tool
The LINBIT® deployment tool is a graphical tool that steps you through the process of installing and configuring LINSTOR® in a cluster of nodes. LINSTOR is a software-defined storage (SDS) solution that you can use to build high availability (HA) and disaster recovery (DR) solutions for critical applications and data. By using the deployment tool, […]
Securing the LINSTOR REST API with Token Authentication
LINSTOR® 1.34 introduces bearer token authentication, a straightforward way to restrict access to its REST API. Before this release, securing the API required setting up LDAP integration or mutual TLS client certificates, both of which add operational complexity. Token authentication gives you the same access control with far less setup. A single command enables it, […]
Hidden Software Gems
This week, I want to write about hidden software gems. My first example is an NFS server. When you search the internet for NFS server and Linux, inevitably, you will end up reading about the kernel-NFS server integrated with the Linux kernel. But there is a second implementation that gets much less attention: the NFS-Ganesha […]
Launching the Deployment Tool: Effortless Cluster Setup
Last month I discussed how AI enabled me to bring my dream of a simpler way to deploy LINBIT software to a reality. Now after much testing and deliberation, I am pleased to announce our LINBIT deployment tool, or “Nightfury” for those on the inside who remember the project’s first working title. Although the vision of […]
GitLab High Availability With DRBD & Pacemaker
GitLab is a DevOps platform that many organizations and developers rely on around the clock, nearly every day of the year. You can install it as a self-managed, standalone web application, but a single instance is always a single point of failure. This article guides you through installing and configuring a highly available (HA) GitLab […]
Using Volume Group Snapshots with LINSTOR in Kubernetes
Version 2.10.0 of the LINSTOR® Operator for Kubernetes, developed by LINBIT®, introduces support for volume group snapshots, a feature that enables crash-consistent, point-in-time snapshots of multiple persistent volumes simultaneously. Kubernetes 1.36 promoted the VolumeGroupSnapshot API to General Availability (GA) under the groupsnapshot.storage.k8s.io/v1 API group. Before volume group snapshots, a Kubernetes operator could only take snapshots of one persistent […]
