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 […]
RHEL Compatible Distribution
You may have noticed that the newsletter got one week off from its usual cadence. That is due to my two-week summer vacation. We spent a few days at a nice lake in southern Austria. We enjoyed hiking, some via ferratas, and climbing in the Dolomites in Italy. It was amazing seeing how quickly my […]
Deploy a LINSTOR Cluster Using Ansible
LINSTOR®, the software behind LINBIT®’s software defined storage solutions, can be integrated into many different platforms and many different environments. Most of LINSTOR’s platform integrations require that a LINSTOR cluster be configured before you’re able to install our respective driver and dynamically create replicated DRBD® volumes using said platform. While we at LINBIT are very […]
Making Nagios XI Highly Available on RHEL 9 by Using DRBD & Pacemaker Tech Guide
LINBIT® has an updated and expanded technical guide available with instructions for making a Nagios XI deployment highly available by using DRBD® and Pacemaker on a Red Hat Enterprise Linux (RHEL) 9 two-node cluster. A Meeting of Industry Trusted Solutions Nagios XI is an industry standard for infrastructure monitoring and intelligence gathering. Nagios is installed […]
Thoughts on Red Hat’s Source Repository Changes
Recently, Red Hat’s change in how they distribute the source code of their distro caught my (and the open source world’s) attention. The Register has an excellent historical summary, and there is an article by Bradley M. Kuhn discussing how this move aligns with the GPL. A few days later, a follow-up blog post by Mike McGrath expressed that he sees no […]
The Benefits of Hyperconverged Infrastructure
Hyperconverged infrastructure (HCI) is a computer systems architecture that abstracts the compute, storage, and networking components of the architecture by using their software-defined functional equivalents and is run from a single system, rather than across multiple systems. The LINBIT® software-defined storage (SDS) solution is often used in HCI to provide, as you might guess, the […]
DRBD 9.2 Updates
The eight-week cadence brings the new DRBD releases 9.1.15 and 9.2.2. The two releases contain roughly the same bug fixes. What these bug fixes have in common is that the underlying bugs trigger very seldom. We found one while using drbd-9.2 in our internal virtualization cluster for our lab infrastructure. Via the ‘eat your own dog […]
An Introduction to LINBIT SDS Management
As part of ongoing efforts to make LINBIT® software-defined storage (SDS) solutions better understood and more widely used, the LINSTOR® Users Guide has undergone a major change. The guide now has an introductory chapter that explains how the LINSTOR component of LINBIT SDS works and deploys storage. It also explains important concepts and terms that are used […]
LINBIT SDS is now on Xinnor xiRAID
LINBIT SDS and xiRAID have proven to work exceptionally well together, and with LINBIT SDS now on Xinnor xiRAID, I wanted to cover the subject on our blog. Linux is not short of software RAID options: Xinnor is a company from Israel that has spent a long time researching and optimizing software RAID. Their solution […]
