Using LINSTOR with Storj S3 Storage for Disaster Recovery
Besides being able to ship storage snapshots internally to the same LINSTOR® cluster, or to a different “remote” LINSTOR cluster, LINSTOR administrators can also ship storage snapshots to S3 compatible storage. MinIO and Amazon S3 are examples of this that articles on this blog have explored before. Storj is an intriguing open source S3 compatible storage offering […]
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 […]
LINBIT SDS & SUSE Virtualization
A few newsletter editions ago, I wrote about the trend of using Kubernetes clusters for managing VMs and its original purpose of orchestrating containers. The commercial players’ products are OpenShift virtualization, SUSE Virtualization (formerly Harvester), alauda.io, Ænix’s Cozystack, and potentially more I am unaware of. I can now share that LINBIT SDS has become a formally […]
Open Source VMware Alternatives That Can Integrate With LINBIT Storage Solutions
This article contains content contributions from LINBIT® team members: solutions architects Matt Kereczman and Joel Zhou, CEO Philipp Reisner, and developer Moritz Wanzenböck. If the Broadcom VMware acquisition negatively impacts you, you might be looking around for possible VMware alternatives, especially if you have customers who are also affected. Or maybe you have not been […]
LVM, LVM-thin, or ZFS
Since LINSTOR supports LVM, LVM-thin, and ZFS, we often get questions about which of the above lower-level storage virtualization technologies we recommend. The answer is, as usual, it depends on your requirements. If you only look for performance, no matter which features are available, the answer is LVM (traditional). If you want to have snapshots […]
Discover Our Approach to Events & Conferences
I led a few discussions last year based on how valuable events and conferences were to us. While I have always appreciated the opportunity to connect with our clients and present our software at events, you have to balance that with the outcomes. I am a big fan of “in person”. While deals don’t normally […]
DRBD Client (Diskless Mode) Performance
Introduction This blog post will examine the performance of DRBD® in diskless mode. DRBD version 9.0 introduced a feature that is now used in nearly all LINSTOR® integrated clusters: DRBD diskless attachment, otherwise known as DRBD clients. With this feature, you can have a DRBD node which has no local replica itself. Essentially, the client node […]
Bringing a LINSTOR Driver to Incus
In my last newsletter, I mentioned the growing burden of maintaining all the integrations for LINSTOR with various workload orchestrators. When the open-source community creates an integration driver, that not only takes that burden off my team but also implies that the community perceives LINSTOR as an accepted open-source storage solution. Incus is a workload […]
Exploring LINBIT Software Relationships for Building Resilient, Scalable, & Integrated Data Storage Solutions

At the heart of the LINBIT software ecosystem are DRBD® and LINSTOR®, two technologies that provide a foundation for building resilient, scalable, and integrated storage solutions. What makes LINBIT storage software truly powerful and unique is flexibility. I […]
Documenting a LINSTOR Automatic Resource Placement Feature: Ensuring a Number of Resources on Nodes of a Different Type
In this article, I will explore the LINSTOR® –x-replicas-on-different feature, and my efforts to document the feature for the LINSTOR User Guide. This was an incredible journey. An alternative title to this article might have been “Documentation Adventures in LINSTOR-land”. The –x-replicas-on-different feature, introduced with LINSTOR server version 1.28.0 and LINSTOR client version 1.23.0, expands on the automatic resource placement […]
