Managing Software-Defined Storage with the LINBIT GUI
A Visual Approach to LINBIT SDS Here at LINBIT®, we live at the shell prompt, but on occasion, getting a graphical view of things can provide benefits. This is why we developed the LINBIT GUI, a graphical user interface (GUI), for the LINBIT SDS stack (LINSTOR®, DRBD®, and related software). Open source code for the […]
Perspectives on Retaining Customers of Free Software
In this first edition of what I intend to be a quarterly newsletter, I want to talk about a topic that I think about every day, as someone who helps run a profitable company based on open source software. That topic is how LINBIT® attracts and retains customers when its software is open source and […]
DRBD Release & Upcoming Events
The newsletter this week coincides with a DRBD release. The changelog of the most recent DRBD releases – 9.1.22 and 9.2.11 – shows that each fix addresses bugs triggered only in rare corner cases. First, the described non-fatal signal during an auto-promote triggered at a customer with security scanning software installed, such as virus scanners or Endpoint […]
Where to Find LINBIT Documentation
This blog post aims to point to the various resources that document LINBIT open source software. Because some people might find this post after having an in-the-moment need and then searching for a specific type of documentation resource, LINBIT documentation resources are listed here and linked to the sections in this post that describe them: […]
NFS High Availability on RHEL 9 with DRBD Reactor: A How-To Technical Guide
The Deploying an HA NFS Cluster with DRBD and DRBD Reactor on RHEL 9 or AlmaLinux 9 how-to technical guide gives instructions for setting up and configuring a high-availability (HA) NFS 3-node cluster, by using DRBD® and DRBD Reactor. This popular guide walks you through how to set up this HA cluster by using open source software […]
Configuring Tiered Storage in CloudStack Using LINSTOR
One of the benefits of integrating LINSTOR®, the LINBIT® developed software-defined storage utility, with Apache CloudStack is that you can use it to compliment CloudStack’s disk offerings to provide tiered storage within CloudStack. Tiered storage just means different types of storage, for example, faster or slower storage. Having tiered storage within a system or platform […]
Distributing Volume Replicas for High Availability & Disaster Recovery Using LINSTOR
LINSTOR® has supported using auxiliary node properties to fine tune LINSTOR’s logic for where in the cluster LINSTOR should place DRBD® volume replicas when you don’t explicitly name nodes. The auxiliary properties, also known as “AuxProps”, are key value pairs placed on nodes in a LINSTOR cluster. When you combine auxiliary node properties with LINSTOR options such […]
A Proactive Approach Towards Ransomware ProtectionÂ
Every year, the research firms’ analysts send questionnaires and conduct interviews. The new trend I have noticed in the analysts’ questions is a proactive approach towards ransomware protection. It seems that the National Institute of Standards and Technology (NIST), a part of the US Department of Commerce, wrote in a publication on Ransomware Risk Management that ransomware […]
Security Best Practices For LINSTOR Software-Defined Storage Clusters
LINSTOR®, developed by LINBIT®, is a robust open source software-defined storage system designed for managing block storage devices in large-scale clusters. It simplifies the creation, management, and replication of storage resources across diverse environments, enhancing both performance and reliability. Securing LINSTOR is crucial to protect sensitive data, ensure system integrity, and maintain high availability, particularly […]
DRBD-reactor over Pacemaker
DRBD-reactor is one of our younger projects, but did you realize it’s already three years old? For some projects, three years is not a lot, but drbd-reactor does what it should and has reached a state of stability — both from the point of view of feature completeness and that it has been a while […]
