Kubernetes High Availability for Stateful Workloads
LINBIT® is a company with deep roots in Linux High Availability (HA). Because of this, LINBIT has some opinions on what HA is, and how it can be achieved. Kubernetes’ approach to HA generally involves sprawling many replicas of an application across many cluster nodes, therefore making it less impactful when a single node or application […]
AWS Marketplace Listing for LINSTOR, DRBD, & DRBD Reactor

Deploying LINSTOR by Using a Juju Charm for Production-Ready Kubernetes Storage
This blog is a walk-through tutorial on how to deploy LINSTOR®, by using a LINBIT® authored Juju charm, into a MicroK8s environment. You can use LINSTOR as a full-featured and production-ready replacement for MicroK8s’s “hostpath” storage. Defining Terms LINSTOR is an open source software-defined storage (SDS) management solution developed by LINBIT. LINBIT also develops DRBD®, […]
Creating a Self-healing Cluster Using LINSTOR’s Auto-evict Feature
When it’s time for the satellite to leave the cluster, the controller takes action! LINBIT® introduced LINSTOR®’s auto-evict feature starting with LINSTOR version 1.10. In simple words, the feature evicts one of the satellite nodes from the cluster. But the possibilities that the feature opens up for you, including creating a self-healing cluster, are more […]
NuoDB in EKS with LINSTOR for Persistent Storage
In the summer of 2019 LINBIT® and NuoDB collaborated on some testing to see how well the two performed together in Google Cloud Platform (GCP). The original blog can still be read here if you’re curious what was written. Spoiler: NuoDB and LINSTOR® performed very well together, with LINSTOR’s synchronous replication between zones adding negligible overhead to […]

Kubernetes Operator: LINSTOR’s Little Helper
Before we describe what our LINSTOR® Operator does, it is a good idea to discuss what a Kubernetes Operator actually is. If you are already familiar with Kubernetes Operators, feel free to skip the introduction. Introduction CoreOS describes Operators like this: An Operator is a method of packaging, deploying and managing a Kubernetes application. A […]
Key/Value Store in LINSTOR
Recently we introduced a Key/Value store in LINSTOR® and exposed it in a developer-friendly way in the Python API (python-linstor). The first question is why would one want such a Key/Value store in LINSTOR when there are many high performance implementations such as etcd. The request for a K/V store was mainly driven by LINSTOR […]
