The Longhorn team is thrilled to share the general availability of Longhorn v1.9.0. This update is all about making your storage experience more resilient, more observable, and a lot less stressful. Building Resilience: Offline Replica Rebuilding In distributed systems, failures aren’t a matter of “if,” but “when.” With v1.9.0, Longhorn introduces offline replica rebuilding. This means that if a replica goes down, Longhorn can now recover it even when the volume is detached.
