Stage 7: SSH architecture, SMART attribute monitoring, drive reset, and polish
SSH (app/ssh_client.py — new):
- asyncssh-based client: start_smart_test, poll_smart_progress, abort_smart_test,
get_smart_attributes, run_badblocks with streaming progress callbacks
- SMART attribute table: monitors attrs 5/10/188/197/198/199 for warn/fail thresholds
- Falls back to REST API / mock simulation when ssh_host is not configured
Burn-in stages updated (burnin.py):
- _stage_smart_test: SSH path polls smartctl -a, stores raw output + parsed attributes
- _stage_surface_validate: SSH path streams badblocks, counts bad blocks vs configurable threshold
- _stage_final_check: SSH path checks smartctl attributes; DB fallback for mock mode
- New DB helpers: _append_stage_log, _update_stage_bad_blocks, _store_smart_attrs,
_store_smart_raw_output
Database (database.py):
- Migrations: burnin_stages.log_text, burnin_stages.bad_blocks,
drives.smart_attrs (JSON), smart_tests.raw_output
Settings (config.py + settings_store.py):
- ssh_host, ssh_port, ssh_user, ssh_password, ssh_key — all runtime-editable
- SSH section in Settings UI with Test SSH Connection button
Webhook (notifier.py):
- Added bad_blocks and timestamp fields to payload per SPEC
Drive reset (routes.py + drives_table.html):
- POST /api/v1/drives/{id}/reset — clears SMART state, smart_attrs; audit logged
- Reset button visible on drives with completed test state (no active burn-in)
Log drawer (app.js):
- Burn-In tab: shows raw stage log_text (SSH output) with bad block highlighting
- SMART tab: shows SMART attribute table with warn/fail colouring + raw smartctl output
Polish:
- Version badge (v1.0.0-6d) in header via Jinja2 global
- Parallel burn-in warning when max_parallel_burnins > 8 in Settings
- Stats page: avg duration by drive size + failure breakdown by stage
- settings.html: SSH section with key textarea, parallel warn div
