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 with it.
Another update I have this week is the votable Software Roadmap. An added feature – only visible to LINBIT customers with a login at my.linbit.com – is the ability to view the roadmap in the navigation bar and even vote on the order of the planned roadmap items. I believe this is a good addition to its functionality, ensuring we continue to deliver the features that matter the most to our users.
Moving on to other news, our friends at OpenSVC have published a HOWTO on using OpenSVC to manage a QEMU/KVM guest on top of DRBD, which also demonstrates live migration of that guest between the host machines. OpenSVC is a workload orchestrator that manages plain services, containers, and VMs. It has built-in storage orchestration capabilities and recently gained support for managing DRBD9.
Regarding the latest LINBIT content, the team has released a range of new Kubernetes posts in recent weeks, and that continues with ‘Dynamically Creating HA Persistent Volumes in Kubernetes by Using LINSTOR.’ The blog explains how using LINSTOR helps you abstract and manage persistent block storage resources in Kubernetes, enabling the operation of stateful applications at scale. A low-resource-consuming, high-performing solution designed for enterprise environments!
Additionally, ‘Resolving Version Mismatch Issues in LINSTOR’ is a new Knowledge Base post that explores some of the common causes of a version mismatch message in LINSTOR. Of course, the post goes on to provide the solutions for anyone experiencing any issues.
Regarding software updates, we have released LINSTOR Operator 2.10.3, LINSTOR GUI v2.2.0, python-linstor/linstor-client 1.27.1, and linstor-server 1.33.0.
