Replication Speed and CPU Efficiency Improvements in DRBD 9.3.1

The release of DRBD® 9.3.1 brings with it a “streaming I/O” feature. This feature means that DRBD can allocate compound pages from the kernel as I/O buffers. When applications make large I/O requests or streaming accesses, using compound pages can improve performance because DRBD will use CPU resources more efficiently. Background on DRBD memory allocation […]
Four Claude-Assisted LINBIT Projects & drbd-9.3.1

In the last few weeks, four LINBITers approached me to show me something. In all four cases, it was people not working in development. Two solution architects, one manager, and my contact for security and compliance. And all four presented LINBIT-relevant tools they created using Claude code. I therefore can’t help but notice the trend […]
Cybersecurity & What LINBIT Does

For a long time, when I told people that LINBIT® helps secure data, I would occasionally hear the reply, “You secure data from bad actors, so you are providing something like a firewall.” Then, of course, I replied with an explanation that LINBIT is about data replication and that users mainly want it to protect […]
Backing up or Migrating a Kubernetes Deployment by Using Velero & LINSTOR

Authors: Joel Zhou & Michael Troutman — In a Kubernetes cluster that has persistent storage managed by LINSTOR®, you bring high availability (HA) and data locality features to the persistent data that your applications and services rely on. To complement a running-in-production or enterprise Kubernetes deployment involving persistent data, you will likely want an off-site […]
PostmarketOS’s Stance Has Some Parallels with Luddism

We continue to adopt Claude Code for our software work. Since I switched from Opus 4.5 to the 4.6 model, it feels even better. It is an awesome tool that fundamentally changes the world of software development. Recently, the PostmarketOS open-source project published a statement on contributing and AI. It discourages the use of AI tools, […]
Production-ready High Availability for Proxmox VE with LINSTOR

Proxmox VE is an open source platform for running and managing KVM virtual machines (VMs) and LXC containers. For an overview of the Proxmox VE platform and how it compares to other open source virtualization management platforms, you can read “Comparing Open Source Virtualization Platforms” on the LINBIT® blog. A cornerstone of Proxmox VE design is simplicity […]
Highly Available NFS for Proxmox With LINSTOR Gateway

Attaching an NFS share to your Proxmox cluster is a convenient way to add reliable storage for backups, ISO images, container templates, and more. If LINSTOR® is already an integral part of your Proxmox cluster, LINSTOR Gateway makes it easy to create highly available NFS exports for Proxmox. In a recent video, we covered 10 Things […]
Create a Highly Available iSCSI Target Using a LINSTOR Gateway Cluster

This tutorial will teach you how to set up a highly available iSCSI target by using LINSTOR® Gateway. Here is the ideal starting point to help you get off the ground as a new LINSTOR Gateway user. The basic principles from this tutorial also apply to using LINSTOR Gateway to set up NVMe-oF or NFS […]
Disaster Recovery With RustFS & LINSTOR in Kubernetes

Introduction RustFS is an open source S3-compatible storage system written in Rust. Version 1.0.0 was released through GitHub in July 2025. The software is still tagged as in an alpha state but with changes in the open source S3 object storage landscape, the project has been building interest and attraction. Because LINSTOR® can ship and […]
Using minikube to Get Started With LINSTOR in Kubernetes

This article gives you step-by-step instructions for setting up a minikube virtual machine (VM) environment for testing and exploring LINSTOR® in Kubernetes. minikube is a local Kubernetes environment on a single host machine that people often use to get up and running quickly, usually for testing or proof-of-concept purposes. Because installing and setting up minikube […]
