June 2026 monthly summary for deckhouse/sds-node-configurator focused on stabilizing LVM-based device discovery and preventing duplicate Volume Group names. Delivered a targeted bug fix that restores default device-discovery behavior by removing an overly permissive blanket accept rule in LVMGlobalFilter, addressing issues when PVs are visible through multiple aliases and preventing VG name duplication. Implemented a guard test to prevent regression and ensured no unintended side effects on LVM’s device filtering. This work reduces operational risk in environments with non-standard device paths and improves reliability of LVM-based configurations.

Concise monthly summary for 2026-05 highlighting delivered features, key fixes, impact, and skills demonstrated for the deckhouse/sds-replicated-volume project.

April 2026 performance summary for deckhouse/sds-node-configurator focused on delivering a unified scheduling experience for SDS volumes, improving reliability, and reducing operational delays. The month featured a major feature delivery, stability fixes, and foundational reliability improvements that directly increase scheduling efficiency, error visibility, and maintainability across the SDS stack.

February 2026, deckhouse/sds-local-volume: Streamlined local storage configuration by removing the enableThinProvisioning parameter, simplifying local storage class setup and validation. This change reduces configuration steps, eliminates an extra code path in the LSC validation webhook, and updates QUICK_START and CONFIGURATION docs accordingly. Committed as 188b62c1de5da784ce3c2601db817f74bfa1d392.

Monthly summary for 2025-11 focused on deckhouse/sds-local-volume: delivered targeted features to improve certificate management and deployment reliability, plus comprehensive documentation improvements to enable safer production usage. Highlights include changes to deployment configurations for certificate handling and expanded module documentation covering thin provisioning, csi-node naming, and snapshot support.

Month: 2025-10 — Concise monthly summary focused on delivering storage reliability, automation, and cross-OS robustness for Deckhouse. Highlights include documentation-driven configuration clarity, automated recovery on mount failures, and hardened cleanup workflows across operating systems. These efforts reduce manual intervention, improve security posture, and enable more predictable storage behavior in production.

July 2025 monthly summary: Key security and reliability improvements across two Deckhouse repositories. SDS Node Configurator implemented security hardening by removing unused PodMonitor configuration, binding readiness and liveness probes to localhost, and introducing environment variables for probes and metrics port, reducing attack surface. CSI-NFS introduced a wrapper to intercept and modify mount/umount commands to always include -n for mounting operations and integrated the wrapper into the build; added mountPermissions support for volume snapshots to ensure consistent file permissions during creation and snapshot operations. These changes improve security posture, reliability of CSI operations, and maintainability.

June 2025 monthly summary: Delivered stability improvements and feature consolidation across SDS repositories. Key items include a bug fix enabling proper Linstor node access to LVM backup and runtime directories, and the deprecation/removal of the sds-drbd module with migration guidance to sds-replicated-volume. These efforts reduce maintenance complexity, improve deployment reliability, and align with current platform capabilities, delivering measurable business value through more stable deployments and clearer module governance.

April 2025: Delivered security and reliability improvements across CSI storage: implemented least-privilege ServiceAccount for the CSI node and updated controller deployment; fixed image build issues by adding Git to the linstor-csi image to enable Werf workflows; strengthened NFS readiness with RPC-with-TLS support and TLShd service fixes, plus comprehensive bilingual documentation and FAQs. These changes improve security posture, reduce build friction, and enhance deployment reliability for production users.

February 2025 focused on security, reliability, and security-hardening across core storage components, delivering concrete features and stabilizations with clear business value. Key features include TLS-secured RPC for CSI-NFS with configuration validation and alerting, DRBD build stabilization and version alignment, ALT Linux build-environment standardization, and security hardening for CSI node service accounts. These efforts reduce misconfiguration risk, improve cross-component compatibility, and streamline CI/CD and deployment workflows.

January 2025 (deckhouse/csi-nfs) focused on stabilizing webhook-driven storage interactions and standardizing patch deployment. Delivered a critical RBAC fix allowing webhooks to access storage.deckhouse.io API resources (nfsstorageclasses) with GET/LIST/UPDATE/PATCH, improving automation and reliability of storage-related webhooks. Centralized patch management for csi-driver-nfs by relocating patching logic to werf.inc.yaml, adding git tooling and switching to git apply for .patch files, which standardizes patch application and enhances reproducibility across environments. These changes contribute to more predictable deployments, reduced manual intervention in patching, and stronger security through explicit access controls.

In December 2024, delivered a focused set of CSI-NFS enhancements in deckhouse/lib-helm to improve storage reliability and deployment stability for Kubernetes workloads. Implemented conditional hostNetwork handling, pod-reloader annotations for the csi-nfs chart, and liveness probe adjustments to gracefully handle the absence of HOST_IP when hostNetwork is disabled. These changes reduce deployment flakiness, improve runtime stability, and simplify operations across clusters with varying network configurations.
