## [Unreleased] |
|
| 9 | ||
| 10 |
### Fixed |
|
| 11 |
- Invalid `ExecStop` syntax in `tb-enlist@.service` caused failed unit teardown on Thunderbolt device removal [ISSUE-2026-001] |
|
| 12 |
- Tapia-Baobab Thunderbolt recovery path hardened after reboot-time disconnect/reconnect events [ISSUE-2026-001] |
|
| 13 |
- `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] |
|
| 14 | ||
| 15 |
### Added |
|
| 16 |
- Automatic Thunderbolt recovery worker (`tb-recover.service`) and periodic timer (`tb-recover.timer`) for flap resilience [ISSUE-2026-001] |
|
| 17 | ||
| 18 |
### Changed |
|
| 19 |
- `tb-recover.sh` now escalates recovery by restarting `bolt.service` when rescan alone does not recreate thunderbolt net devices [ISSUE-2026-001] |
|
| 20 |
- `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] |
|
| 21 |
- `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] |
|
| 22 |
- `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] |
|
| 23 |
- Added standardized shared-runtime install/uninstall flow that manages scripts, unit files, and udev rules without rewriting host network configuration |
|
