Cozystack

🚀The Cozystack team has open-sourced Blockstor, a control plane for block storage in Kubernetes: LVM and ZFS as backends, replication over DRBD, and a LINSTOR-compatible REST API. The project lives in the cozystack organization and is developed as part of Cozystack, a platform accepted into the CNCF Sandbox. The license is Apache 2.0. 🔥The main thing that makes it worth a look: it is not a fork, and it is not a wrapper. Blockstor is written from scratch in Go, but it speaks the same REST API as LINSTOR — so all the client tooling you already run keeps working without a single change: the linstor CLI, linstor-csi, piraeus-operator, and the golinstor library.
