# Changelog All notable changes to the Madagascar cluster will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [Unreleased] ### Fixed - Invalid `ExecStop` syntax in `tb-enlist@.service` caused failed unit teardown on Thunderbolt device removal [ISSUE-2026-001] - Tapia-Baobab Thunderbolt recovery path hardened after reboot-time disconnect/reconnect events [ISSUE-2026-001] - `tb-enlist@.service` now stays active until `network.target` stops, so NFS storages routed over `thunderbridge` can unmount cleanly before Thunderbolt ports are detached; this is the Thunderbolt-side fix for the cluster-wide maintenance shutdown incident [ISSUE-2026-002] ### Added - Automatic Thunderbolt recovery worker (`tb-recover.service`) and periodic timer (`tb-recover.timer`) for flap resilience [ISSUE-2026-001] ### Changed - `tb-recover.sh` now escalates recovery by restarting `bolt.service` when rescan alone does not recreate thunderbolt net devices [ISSUE-2026-001] - `tb-recover.sh` now includes cooldowned Thunderbolt NHI PCI `remove+rescan` fallback (soft replug path) for reboot cases where netdev is missing [ISSUE-2026-001] - `tb-recover.sh` now retries the Thunderbolt NHI reset within the same recovery run when a peer xdomain host reappears without its `*.0` network service [ISSUE-2026-001] - `tb-recover.sh` now probes the expected peer behind each Thunderbolt port and cycles the affected interface with `ifdown/ifup` when a port stays attached but logically detached [ISSUE-2026-001] - Added standardized shared-runtime install/uninstall flow that manages scripts, unit files, and udev rules without rewriting host network configuration ## [2025-10-30] ### Fixed - Thunderbolt interfaces not in bridge after MTU fix deployment [ISSUE-2025-002] - MTU reset to 1500 after systemctl restart networking [ISSUE-2025-001] ### Added - Issue tracking system with structured templates - Defense-in-depth for thunderbolt network configuration (udev + ifupdown2 hooks) ### Changed - Enhanced udev rules for thunderbolt device handling - Updated network interfaces.d with post-up hooks for MTU and bridge membership ## [2025-10-29] ### Added - Initial issue tracking setup - COPILOT_BACKUPS_INSTRUCTIONS.md for backup procedures - CHANGELOG.md for change documentation
