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 Detection and Response (EDR) software.
I speculate that such security software sends fresh processes a STOP and CONT signal to investigate them. Only a tiny part of our user base has such software installed besides DRBD and LINSTOR (for the record, CrowdStrike is also an EDR software).
Secondly, the forget-peer operation takes only milliseconds and is executed when you remove a resource’s replica. When you have a disk failure at the same time, the bug is triggered. The probability of such two events coming together is extremely low.
With the release out of the way since the beginning of the week, we have started preparing for the upcoming Container Days in Hamburg, September 3-4, and the Open Source Summit in Vienna, September 16-18.
I am honored to present at the Container Days and will be with Moritz, our lead developer for all things K8s, at the conference. Meet us there at the LINBIT booth – C16.
We are thrilled that the Linux Foundation is bringing the Open Source Summit to LINBIT’s hometown, Vienna, the capital of Austria. You will also have the chance to meet and talk to us at our booth there – G/S16.
Moving onto the LINBIT blog, ‘Comparing Open Source Cloud & Virtualization Platforms’ written by Documentation Specialist Michael Troutman, examines four platforms that our storage solutions integrate with: Apache CloudStack, OpenNebula, Proxmox VE, and Xen Orchestra.
The blog post provides a neutral perspective on each solution, not aiming to recommend or show favor but to provide an easy-to-follow overview of the highlights and characteristics of each. After all, each platform is unique and offers users slightly different qualities.
Additionally, we recently published, ‘Kubernetes CSI Plugin for LINSTOR.’ Much has changed over the years in how LINSTOR is typically deployed in Kubernetes clusters. However, the CSI plugin remains the bridge between Kubernetes and LINSTOR’s replicated block storage.
Among our recent software updates is WinDRBD 1.1.19. An optimization implemented in 1.1.8, which speeds up initial bitmap read on attachment, was patched out since it caused troubles on certain setups with storage backend throttling.
