Release Spotlight: Longhorn v1.7.0
Longhorn is a distributed block storage for Kubernetes and a CNCF Incubating project. Its recent v1.7.0 introduced several new V2 Data Engine features, including online replica rebuilding, data plane live upgrade, filesystem trim (efficient unused space reclaiming), and block-type disk support for SPDK AIO, NVMe, and Virtio bdev drivers. Note that V2 Data Engine is still considered a preview feature.
This new Longhorn version also added COS (Container-Optimized OS) support, high availability improvements (HA for backing images, RWX volumes fast failover), periodic and on-demand full backups, and a brand-new CLI tool to manage Longhorn (
longhornctl). You can find more details in this release announcement.Other noticeable updates in the Cloud Native space:
