In this post we're going to explore using LVM to reduce the space needed by a dual rootfs setup. In a typical dual rootfs setup, the device needs to have two times the space needed by the rootfs partition, in order to have an inactive partition to stream a new update into. But in a typical patch update, not that much will have changed from what's already on the active partition. Perhaps a few libr...

All of you know about Kubernetes, the open-source container-orchestration system for automating application deployment, scaling, and management. Over time, it is becoming the de-facto standard to automate the deployment, scaling, and operations of container-based workloads in the cloud. The Cloud-Native Computing Foundation (CNCF) is responsible for the certification of the Kubernetes distribution...

Have you ever wanted to robustly update a bunch of devices, but you can't because they're already in the field, and they are not configured for a robust dual root filesystem layout? Today, we are exploring converting live devices from stock single partition devices into robust dual partition devices.

There has been a thread Mender Hub about live migration of devices to the dual partition devic...
