Discover System76: A Partner in Open Source
In the past I’ve written about how LINBIT uses open source software throughout our infrastructure. Our commitment to open source extends further than our code and our business applications. We also support the hardware vendors that contribute back to the open source community. One such vendor is System76. We’ve used their hardware for servers, laptops, […]
Kubernetes Roundup – LINSTOR Operator 2.12.0 Release & Updates
I’ll begin this Kubernetes roundup by sharing details about the new LINSTOR Operator 2.12.0 release. The new standout feature is support for shared storage. The Operator can now register LVM storage pools backed by storage shared between nodes, such as a SAN. LINSTOR CSI builds on this: RWX block volumes no longer need a DRBD […]
Insight into the latest DRBD Release
Just a couple of days ago, I released drbd-9.2.20 and drbd-9.3.4, which was an unusual release. As I explained in the release notes, we fixed more issues than in any previous development cycle. This is because the team has used ClaudeCode since the start of the year. From our first experiments, it took around six […]
Ansible Inventory Groups for LINSTOR
A well-structured Ansible inventory is fundamental to an automated LINSTOR® cluster deployment. This blog post shows how to structure inventory groups for Day 1 installation and Day 2 operations. It assumes familiarity with Ansible and previous experience setting up a LINSTOR cluster. Inventory group overview Core LINSTOR inventory groups: linstor_controllers: LINSTOR controller nodes linstor_satellites: LINSTOR […]
Meet LINBIT at KubeCon North America 2026 & a LINSTOR in Kubernetes Development Roundup
LINBIT® will exhibit at the KubeCon and CloudNativeCon North America 2026 conference, booth 301. The conference takes place November 9-12, at the Salt Palace Convention Center, Salt Lake City, Utah. As Kubernetes continues to evolve, so does the LINBIT team’s development of LINSTOR® in Kubernetes and the upstream CNCF Piraeus Datastore project. 2026 has brought […]
Meeting Your HA, DR, & SDS Goals with LINBIT Software
LINBIT® software covers DRBD® and LINSTOR®, together with DRBD Reactor and its promoter plugin, LINSTOR Gateway, WinDRBD, and LINBIT SDS for Windows. Teams evaluating high availability (HA), disaster recovery (DR), and software-defined storage (SDS) can use these tools to replicate block storage reliably across Linux and Windows nodes, automate failover with or without specialized fencing […]
Highly Available NFS Exports with DRBD & Pacemaker
This blog post explains how to configure an NFS server instance in a 3-node high availability (HA) active/passive Linux cluster by using DRBD® and Pacemaker. You can implement this solution with enterprise Linux distributions such as Ubuntu LTS, or Red Hat Enterprise Linux (RHEL). The instructions in this article have been validated on both RHEL […]
Applying Per-Volume I/O Quality of Service Limits with LINSTOR in Kubernetes
Since the release of the LINSTOR Operator version 2.11.0 and the LINSTOR CSI driver version 1.11.3, both developed by LINBIT®, users can attach I/O Quality of Service (QoS) limits to the persistent volumes that LINSTOR® provisions. Users can specify read and write bandwidth and IOPS limits as StorageClass parameters, and every volume created from that […]
LINSTOR is Red Hat Certified for OpenShift Virtualization
LINSTOR® now lists OpenShift Virtualization under Infrastructure features in its Red Hat Ecosystem Catalog listing, next to Container Storage Interface (CSI). It is a single line, only two words on a catalog spec sheet. In this article, I elaborate on what the certification actually means. Red Hat’s own certification conformance suites were run against the LINSTOR […]
Digital Sovereignty’s Impact on Open Source Companies
‘Sovereignty’ is a word we borrowed from statecraft: a sovereign country is independent in its decisions. The term ‘Digital Sovereignty’ is a more recent invention that applies to organizations and even individuals. The European Commission published the EU Cloud Sovereignty Framework (CSF), which breaks sovereignty down into eight objectives: SOV-1: Strategic: ownership and governance are […]
