Configuring Multipath iSCSI Targets in Pacemaker for Higher Availability
LINBIT® has been building and supporting high-availability (HA) iSCSI clusters using DRBD® and Pacemaker for over a decade. In fact, that was the very first HA cluster I built for a client when I started working at LINBIT as a support engineer back in 2014. Searching the Internet for HA iSCSI Pacemaker clusters will return […]
What the New European Cyber Resilience Act Means for the Open Source Industry
In community news, the European Cyber Resilience Act will have a massive impact on Open Source projects and Open Source businesses. The intention is to impose mandatory security requirements on everyone delivering/supplying the software. That by itself is a noble goal. However, it is slightly in contrast to what Open Source licenses do. Open Source licenses limit […]
Kubernetes at the Edge Using LINBIT SDS for Persistent Storage
Edge computing is a distributed computing paradigm that brings data processing and computation closer to the data source or “edge” of the network. This reduces latency and removes Internet connectivity as a point of failure for users of edge services. Since more hardware is involved in an edge computing environment than there is in a […]
Is the Open Source World Under Financial Pressure?
Two weeks ago, the news that EQT is buying back SUSE shares got some attention in the Linux world, which also happens to be when I realized Dirk-Peter van Leeuwen became the new CEO at SUSE earlier this year. EQT acquired SUSE in 2018 and tried to profit by selling the shares piecemeal on the […]
LINBIT Offers Official DRBD Basics Training
LINBIT® is offering an official training package for Linux system administrators who are interested in getting started using DRBD® to create high-availability and high-performance block storage in their clusters. Whether you need highly available storage to back a database, website, virtual machine image hosting, or other storage use cases that you can imagine, this training […]
DRBD Starter Package
LINBIT® has been dedicated to open source since its inception. All of LINBIT’s code is freely available on GitHub, as well as prepackaged downloads on LINBIT.com. However, being open source and freely available doesn’t always mean it’s easily installed. Most of LINBIT’s software and solutions revolve around the DRBD® kernel module. Being a kernel module means […]
Is “Enterprise Linux” fragmented? Will there be RHEL and Open Enterprise Linux?
Following the recent pattern, the discussion about Red Hat’s move to no longer make the source code for RHEL publicly available continues. The most recent development was the Open Enterprise Linux Association announcing its founding by the initial members CIQ (Rocky Linux), Oracle, and SUSE. It is a place where these three organizations share what they consider the […]
Deploying LINBIT SDS in an Air-Gapped Kubernetes Cluster
Authors: Joel Zhou & Michael Troutman — Deploying LINBIT SDS into an air-gapped Kubernetes cluster can be useful when your Kubernetes deployment requires persistent, highly available storage. If you are a LINBIT® customer, you can use a combination of container images from LINBIT and some publicly available container images, and then import them into a […]
A Brief History of Source Code Distribution Practices
First, I’d like to continue the evolving discussion about RedHat’s move to limit its RHEL source code to its paying customers and cut off clones like Alma-Linux and Rocky. The topic has inspired a recent article by John “maddog” Hall. Reading it took me nearly an hour. I like it. I might have gone with the […]
DRBD Reactor & Pacemaker: A Side-by-Side Comparison
In this blog post, I want to expand a little bit further on my colleague, and DRBD Reactor developer, Roland’s post, High-Availability with DRBD Reactor & Promoter. As Roland covered, DRBD® Reactor and its promoter plugin can be used to build simple high-availability (HA) failover clusters. Roland’s article includes an example with a single DRBD resource […]
