Kubernetes Roundup – Software News & Resource Updates
LINSTOR Operator 2.10.4 updates the LINSTOR CSI image to 1.10.5 to be compatible with LINSTOR 1.33. We have intentionally not updated the LINSTOR version itself to the latest 1.33.1, as that is left for the next feature release of our Operator. See the full changelog here – https://forums.linbit.com/t/linstor-operator-2-10-4/1135 As you may know, the release of […]
Agentic Coding
As this is my first newsletter of 2026, I would like to wish you all a Happy New Year! For me, this year will be the Year of AI. For the first time in my 25-year career in the IT industry, I feel this year I will change the way I write software. Over the past […]
Using the LINSTOR Python API to Interface with LINSTOR Clusters in Kubernetes
Introduction to the LINSTOR APIs One of the most notable but easily overlooked features in LINSTOR® is its REST API. Typically, LINSTOR users interact with their LINSTOR clusters by using the LINSTOR command line client utility (also known as the linstor-client) to perform administrative tasks. These tasks include operations such as adding LINSTOR satellite nodes to a cluster […]
Software Roadmap News
This week, I want to share an update on LINBIT’s GUI for LINSTOR clusters. Since the recently released version 2.0, it nicely embeds Grapha graphs of Prometheus metrics in two places: in the node view and at the resource details. Prometheus/Graphana has become very popular in open-source metrics monitoring, so it makes sense to integrate […]
Exploring Homelabbing & Open Source Innovations
With a decent covering of snow on the ground here finally, and the end-of-year holiday season approaching, I’ve been thinking about some homelab maintenance tasks I want to try to knock out. Being thoughtful about maintaining systems is a critically important part of high availability, as I have written about before on the LINBIT blog. This […]
Reducing DRBD Memory Requirements
Over its more than 20 years of existence, DRBD® has earned some renown as data replication software with high performance. Put to the test on some potent hardware, the LINBIT® team has shown impressive benchmarking numbers1. Independent testing has also shown strong results on more conventional hardware2. Performance is one reason DRBD is often used […]
DRBD is a Great Fit for Hyperscalers
As we designed DRBD for applications with demanding I/O requirements, it is a perfect fit for databases. So it is not surprising that a global hyperscaler combined WinDRBD and Microsoft’s SQL Server Web edition to create one of its managed database offerings. Of course, we at LINBIT are proud of being a building block of […]
Dynamically Creating HA Persistent Volumes in Kubernetes by Using LINSTOR
If you need to run stateful applications and workloads in Kubernetes, you will need to make use of Kubernetes persistent volumes. Although Kubernetes might be more well known for and first associated with running stateless applications, infrastructure for persisting data in Kubernetes has been in its code from its early stages. When persisting data in […]
Exciting New DRBD Features
DRBD 9.2.16 and 9.3 are released. While 9.2.16 is the boring bugfix release, drbd-9.3 brings exciting new features. The newest DRBD update now supports the out-of-sync bitmap at different granularities. For the last 25 years, it has been fixed that one bit in that bitmap represents 4096 bytes of storage. That bitmap exists in the […]
Kubernetes Roundup – LINSTOR Updates, RWX, & Events
This edition of the LINBIT Kubernetes newsletter begins with some big software news. We recently released LINSTOR Operator 2.10.0 (and a follow-up bug fix: LINSTOR Operator 2.10.1). Version v2.10.0 brought long awaited support for ReadWriteMany (RWX) volumes, along with Volume Group Snapshot support, integrations for Cluster API, and more. To use RWX after upgrading to […]
