Native Headlamp integrations: - registerResourceTableColumnsProcessor: add Protocol/Pool/Server columns to native StorageClass table and Protocol/Volume Handle to PV table - registerDetailsViewSection: inject TNS-CSI section into PV detail pages - registerDetailsViewSection: inject driver role/status into tns-csi Pod pages - registerDetailsViewHeaderAction: Benchmark shortcut on StorageClass detail - registerAppBarAction: driver health badge (N/Nc M/Mn, color-coded) - Trim sidebar from 6 → 4 entries (Overview, Snapshots, Metrics, Benchmark) TrueNAS API integration: - src/api/truenas.ts: ConfigStore-backed settings, WebSocket JSON-RPC client for pool.query (auth.login_with_api_key + pool.query) - src/components/TnsCsiSettings.tsx: API key + server override settings UI with connection test button - TnsCsiDataContext: fetch real pool stats (size/allocated/free/status) - OverviewPage: three-tier pool capacity display (real data → error → metrics fallback) Documentation: - README, CHANGELOG, CONTRIBUTING, SECURITY - docs/: architecture, deployment (Helm), getting-started, user-guide, troubleshooting CI: - .github/workflows/ci.yaml: lint + type-check + test on PR/push - .github/workflows/release.yaml: workflow_dispatch versioned release Generated with [Claude Code](https://claude.ai/code) via [Happy](https://happy.engineering) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering>

Troubleshooting
Quick Diagnosis
| Symptom | Likely Cause | Fix |
|---|---|---|
| Plugin not in sidebar | Not installed or browser cache | Hard refresh (Cmd+Shift+R / Ctrl+Shift+F5) |
| "TrueNAS (tns-csi)" missing from sidebar | Plugin not loaded | Check Headlamp plugin manager or restart Headlamp pod |
| No StorageClasses listed | Wrong provisioner or driver not installed | See Driver Detection |
| Driver status "Not installed" | CSIDriver object missing | kubectl get csidriver tns.csi.io |
| Protocol/Pool/Server showing "—" | StorageClass missing parameters | kubectl get sc <name> -o yaml to inspect |
| 403 on any page | Missing RBAC | See RBAC Issues |
| Metrics page empty | Controller pod unreachable or no metrics | See Metrics Issues |
| Snapshots tab: "CRD not available" | Snapshot CRD not installed | Install snapshot.storage.k8s.io CRDs |
| Snapshots tab empty (no message) | No snapshots or wrong snapshot class | Check VolumeSnapshotClass driver field |
| Benchmark fails immediately | Missing RBAC for Jobs/PVCs | See Benchmark Issues |
| Benchmark stuck in "Running" | kbench pod not starting | kubectl get pods -n <ns> -l app.kubernetes.io/managed-by=headlamp-tns-csi-plugin |
| Page loads but data is stale | Watch connection dropped | Click the Refresh button or reload the page |
Driver Detection
The plugin detects the tns-csi driver by querying:
GET /apis/storage.k8s.io/v1/csidrivers/tns.csi.io
If this returns 404, the driver shows as "Not installed".
Check:
kubectl get csidriver tns.csi.io
If missing, verify the tns-csi driver is deployed. The driver registers its CSIDriver object on startup.
StorageClass Parameters Showing "—"
StorageClass Protocol, Pool, and Server come from the StorageClass parameters field.
Check:
kubectl get sc -o yaml | grep -A5 "provisioner: tns.csi.io"
Expected output includes:
parameters:
protocol: nfs
pool: tank/k8s
server: 192.168.1.1
If parameters is absent, the StorageClass was created without them — the CSI driver documentation specifies the required parameters for each protocol.
Controller Pods Not Showing
The Overview page shows controller and node pod counts using label selectors:
- Controller:
app.kubernetes.io/name=tns-csi-driver,app.kubernetes.io/component=controller - Node:
app.kubernetes.io/name=tns-csi-driver,app.kubernetes.io/component=node
Check:
kubectl get pods -n kube-system -l app.kubernetes.io/name=tns-csi-driver
If pods exist but aren't showing, verify the app.kubernetes.io/component label is set correctly.
Infinite Loading Spinner
If a page shows a loading spinner indefinitely:
- Check browser console for errors (F12 → Console)
- Check network tab for failed API requests (look for 403, 404, 500)
- Check Headlamp pod logs:
kubectl logs -n kube-system -l app.kubernetes.io/name=headlamp - Try refreshing — the watch connection may have been interrupted
Common API Errors
| HTTP Status | Meaning | Action |
|---|---|---|
401 Unauthorized |
Token expired or invalid | Re-authenticate in Headlamp |
403 Forbidden |
Missing RBAC permission | See RBAC Issues |
404 Not Found |
Resource doesn't exist | Expected for optional resources (CSIDriver, snapshot CRD) |
503 Service Unavailable |
API server overloaded | Wait and retry |
Getting More Information
Browser console:
F12 → Console tab
Look for errors related to tns-csi, headlamp-plugin, or Kubernetes API paths.
Headlamp pod logs:
kubectl logs -n kube-system -l app.kubernetes.io/name=headlamp --tail=100
tns-csi controller logs:
kubectl logs -n kube-system -l app.kubernetes.io/name=tns-csi-driver,app.kubernetes.io/component=controller --tail=100
