🚧 QuorumBD

Distributed Storage for Small Clusters — Without Enterprise Assumptions

QuorumBD is an upcoming free and open source distributed block storage system, currently in active development.

Its goal is simple and deliberately narrow:

To provide reliable, predictable distributed storage for small clusters, SMBs, and HomeLabs — without requiring enterprise hardware, high-bandwidth networks, or excessive operational complexity.

🧠 What QuorumBD Is Designed to Do

QuorumBD is being built for environments where existing solutions are either too heavy or too limited.

It is designed to:

  • run efficiently on 3–9 node clusters
  • work reliably on 1 GbE and 2.5 GbE networks
  • support consumer and mixed hardware
  • provide strong consistency via quorum-based decisions
  • minimize background traffic and hidden state
  • behave deterministically and transparently
  • integrate cleanly into virtualization environments (e.g. Proxmox)
  • designed to support classic mirrored replication as well as erasure-coded data layouts, enabling different trade-offs between redundancy, storage efficiency, and network usage.

The focus is is operational sanity, predictability, and clarity and a high performance even under heavy load.

⚙️ Design Principles

QuorumBD follows a few strict principles:

  • quorum over silent replication
  • explicit failure handling instead of implicit magic
  • simple, documented wire formats
  • deterministic state machines
  • debuggability as a first-class feature
  • no assumption of datacenter-grade infrastructure

In short:
a system designed for real-world constraints, not ideal lab conditions.

🔬 Current Status

QuorumBD is under active development.

At this stage:

  • the architecture is being designed and validated
  • core protocols and state models are defined
  • early implementations and prototypes are in progress

The project is intentionally developed carefully and conservatively, with long-term maintainability in mind.

🗓️ Planned Availability

The first stable release of QuorumBD is currently planned for:

late 2026 or early 2027

QuorumBD will be released as a Free and Open Source product, with open specifications and transparent development.
