The Cozystack team has open-sourced Blockstor: LVM and ZFS backends, DRBD replication, and a LINSTOR-compatible REST API, so existing client tooling keeps working unchanged.
Cozystack v1.6.0 moves tenant Kubernetes workers to Talos Linux, adds tenant-controlled OIDC, a SecurityGroup firewall API, hierarchical quotas, and in-place etcd-operator adoption.
How Cozystack uses LINSTOR and DRBD for synchronous block-level replication on bare metal: setting up storage pools, the replicated StorageClass, and what happens when a node fails.
Cozystack 1.3 brings storage-aware pod scheduling, a managed LINSTOR GUI, a curated VM image catalog, application-level observability, and cross-namespace VM backup restore.
Cozystack v0.40 introduces the LINSTOR scheduler for optimal pod placement near storage replicas, SeaweedFS traffic locality, a new ValuesFrom configuration mechanism, and major platform architecture refactoring.
Cozystack v0.37 replaces the old UI with a new OpenAPI-based Dashboard, introduces the Lineage Webhook for resource tracking, enables PVC expansion in tenant clusters, and makes SeaweedFS S3 buckets discoverable.
Cozystack v0.12 introduces storageClass configuration for all applications, updates Cilium to v1.16.1, adds tenant Kubernetes value overrides, and provides an E2E testing sandbox.
Cozystack v0.6 adds serial console access for virtual machines, ephemeral storage volumes for containerd and kubelet, and automatic etcd quota configuration.
The first feature release of Cozystack introduces ZFS storage support, leader election for the controller, and moves documentation to cozystack.io.
