Highly Available NFS Exports with DRBD & Pacemaker

Highly available NFS

This blog post explains how to configure an NFS server instance in a 3-node high availability (HA) active/passive Linux cluster using DRBD® and Pacemaker. You can implement this solution easily with enterprise Linux distributions such as Ubuntu LTS, or Red Hat Enterprise Linux (RHEL). The instructions in this article have been validated on both RHEL […]

AI at This Year’s Red Hat Summit

I am writing this week’s newsletter from Boston, MA, at Red Hat Summit. AI was central to this year’s keynote, with Red Hat announcing various infrastructure components for AI inference, which did not come as a surprise. Red Hat set the de facto standard for Linux in the enterprise environments. Their goal is to also set […]

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 […]

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 […]
