OpenEBS Mayastor monthly summary for 2025-08 focusing on business value and technical accomplishments across two repositories (mayastor-control-plane and mayastor-extensions). The month delivered new configurability, improved correctness for creation paths, and stronger platform operability via CRD tooling and CI automation. Highlights include implemented pool cluster size configuration and cloning inheritance, CRD generation tooling with CI validation, storage class parameter fixes, and disk pool tunables with accompanying documentation and charts updates. Test coverage expanded around pool size constraints and CRD validation to reduce regression risk.

July 2025 focused on delivering a core storage scheduling improvement and improving maintainability in the mayastor-control-plane. Implemented Volume Scheduling by Pool Cluster Size to ensure volumes are allocated to pools that meet their cluster size requirements, enhancing storage utilization and planning flexibility. Conducted a naming refactor from pool_bs_cluster_size to pool_cluster_size across control plane components to improve clarity and consistency. The change was implemented under the repository openebs/mayastor-control-plane and codified in the commit de17933b9070af173a63caa1e36eb1a762342380 (feat: handle pool cluster_size in volume scheduling). These changes lay groundwork for more granular scheduling policies and easier operator reasoning about resource placement.

June 2025: Delivered the Blobstore Pool Cluster Size Configuration feature in openebs/mayastor-control-plane. This enables configuring the blobstore cluster size for newly created pools via CLI arguments or pool creation requests, with a safe default of 4 MiB and no changes to existing pools. This capability supports workload-driven tuning to improve performance and storage efficiency, while preserving backward compatibility. Commit 1582fa09edd7299d49f75e57e9bfdb2d73d723d8 (feat(pool): allow changing blobstore cluster size).

Month: 2025-05 — Focused feature delivery in openebs/mayastor-control-plane to improve migration resilience and policy-driven scheduling. Implemented soft scheduling for pool migration when prefer-encrypted-pools is enabled, enabling the use of non-encrypted pools when encrypted ones are not readily available. This required updates to registry and volume policy to support soft scheduling preference. Core change delivered via commit 2259e796a1d7b662b0dc0e896aab8ed9dba0c362 (feat(encryption): relaxed replica scheduling during pool migration).

April 2025 monthly summary for openebs MaYaStor projects focused on delivering encryption capabilities and improving migration readiness across control plane and extensions. Key work spanned two repositories and establishes security-first storage workflows: enabling volume-level encryption configuration on creation, and soft scheduling migrations of volumes to encrypted pools when available. The outcomes position us for stronger compliance with data-at-rest requirements and smoother operational migrations with minimal downtime.

March 2025 monthly summary for openebs/mayastor-control-plane: Focused on security and observability enhancements in the registration flow. Key feature delivered: Disk Pool Encryption Feature Status in Registration, enabling tracking of disk pool encryption by updating RegisterRequest to include the new feature and extending NodeFeatures to include diskpool_encryption. The work is backed by commit 30b93af5e82caa822dc8b26bac682a884f9f4a51 ('chore(registration): get pool encryption feature status'). Major bugs fixed: none documented for this period in this repository. Overall impact: improved security posture and governance with better visibility of encryption readiness during node registration, paving the way for policy enforcement and compliance reporting. Demonstrated skills: API design and extension, feature flag/state tracking, clean commit hygiene, and Go/K8s-ecosystem code changes in the mayastor-control-plane.

February 2025 monthly summary for openebs/mayastor-control-plane focused on API scaffolding to enable encryption. Implemented the Pool API encryption field scaffolding within pool creation and import structures, with minimal translation and RPC changes to accommodate a future encryption feature. No encryption logic was implemented this month; the work is purely preparatory to enable secure feature integration while keeping existing behavior intact. Committed under the scaffold change e8d11ebf03d53b01d83dbeb1e839269bc308b1b2.

January 2025 monthly summary for OpenEBS Mayastor work focusing on reliability and correct transport path validation. Delivered critical bug fixes in both the control plane and extensions, improving ha-node transport handling and NVMe-TCP module detection for built-in modules. These changes reduce runtime error loops, improve failover path validation, and enhance overall cluster stability.

2024-11 Monthly Summary: Focused on delivering a reliability boost for NVMe connectivity and strengthening volume lifecycle correctness across Mayastor components. The team shipped a feature in the extensions module and fixed a critical correctness bug in the control-plane, aligning with business goals of higher availability and safer data operations in heterogeneous cluster environments.
