# Health & load review — railiance01 — 2026-07-16
|
||||
|
||||
**Engagement:** eng-coulomb-railiance01-ho-001
|
||||
**Phase:** ramp_up (first live observe)
|
||||
**Access class:** host_observe
|
||||
**Protocols:** load-workload-review + sys-medic subset
|
||||
|
||||
---
|
||||
|
||||
## 1. Executive Summary
|
||||
|
||||
railiance01 is a **2-core / 3.8 GiB** Ubuntu 24.04 single-node k3s host under **severe memory pressure and sustained CPU/load overload**. Root disk capacity is acceptable (~54%). The k3s API was **ServiceUnavailable** during assessment (control plane struggling). No privileged remediation was performed.
|
||||
|
||||
**Overall health: Critical** (confidence: High for host-level memory/load; Medium for full pod inventory due to API unavailability)
|
||||
|
||||
## 2. Health Status
|
||||
|
||||
| Dimension | Status |
|
||||
|-----------|--------|
|
||||
| Aggregate | **Critical** |
|
||||
| Memory | Critical (no swap, PSI elevated, ~hundreds of MiB available) |
|
||||
| CPU / load | Degraded–Critical (load ≫ 2 cores) |
|
||||
| Disk capacity | Healthy (~54% root) |
|
||||
| Disk / logs | Watch (`/var/log` ~5.7G, journal ~4.1G) |
|
||||
| k3s API | Critical / unavailable at sample time |
|
||||
| Network listeners | Watch (expected k3s + SSH; review exposure of 6443) |
|
||||
|
||||
## 3. Findings
|
||||
|
||||
### F1 — Memory exhaustion / no swap
|
||||
- **Severity:** Critical
|
||||
- **Evidence:** MemTotal ~3.8Gi; MemAvailable often <500Mi; SwapTotal 0; PSI memory `full avg60≈24% avg300≈29%`; `kswapd0` long-running
|
||||
- **Why it matters:** OOM risk; thrashing; control-plane instability
|
||||
- **Likely cause:** Workload density (k3s + Forgejo + Temporal + activity-core + state-hub edge + platform pods) on undersized RAM
|
||||
- **Next step:** Human-approved capacity plan (add RAM and/or swap emergency cushion; reduce concurrent workloads). **Do not** kill workloads without owner approval
|
||||
|
||||
### F2 — Load far above CPU capacity
|
||||
- **Severity:** High
|
||||
- **Evidence:** load average ~12/11/16 with `nproc=2`; vmstat shows high `sy` and `wa`, heavy block-in
|
||||
- **Why it matters:** Latency for all services; scheduler saturation
|
||||
- **Likely cause:** Memory reclaim + I/O + k3s restart recovery
|
||||
- **Next step:** Correlate with k3s restart time (~10:39 UTC); re-sample after memory relief
|
||||
|
||||
### F3 — k3s API ServiceUnavailable
|
||||
- **Severity:** Critical
|
||||
- **Evidence:** `sudo k3s kubectl get node` → server unable to handle request; `k3s server` process high CPU shortly after start
|
||||
- **Why it matters:** Cluster ops and many apps depend on API
|
||||
- **Likely cause:** Memory pressure / control-plane restart under load
|
||||
- **Next step:** Re-check API when MemAvailable improves; avoid concurrent heavy kubectl
|
||||
|
||||
### F4 — Large journald footprint
|
||||
- **Severity:** Medium
|
||||
- **Evidence:** `/var/log/journal` ~4.1G of ~5.7G under `/var/log`
|
||||
- **Why it matters:** Disk growth; I/O; eventual fill
|
||||
- **Next step:** Propose `journalctl --vacuum-size=` **with approval** (privileged / system change)
|
||||
|
||||
### F5 — Pending OS package updates (incl. security)
|
||||
- **Severity:** Medium
|
||||
- **Evidence:** `apt list --upgradable` shows many packages (bind9-*, curl, ca-certificates, dpkg, …)
|
||||
- **needrestart:** kernel current (KSTA 1); `unattended-upgrades.service` flagged
|
||||
- **Next step:** Scheduled OS security pass with human approval for upgrades
|
||||
|
||||
### F6 — Reverse tunnel port contention (18765)
|
||||
- **Severity:** Low–Medium
|
||||
- **Evidence:** repeated sshd errors binding 127.0.0.1:18765 address already in use
|
||||
- **Why it matters:** ops-bridge / reverse-forward fragility
|
||||
- **Next step:** Operator cleanup of stale forwards; bridge config audit
|
||||
|
||||
### F7 — Public exposure of k3s API port in UFW
|
||||
- **Severity:** Medium (policy)
|
||||
- **Evidence:** UFW allows 6443/tcp and 8472/udp from Anywhere
|
||||
- **Next step:** Confirm intended threat model; prefer restricted sources if possible (**firewall_change** gated)
|
||||
|
||||
## 4. Immediate Safe Actions (no approval needed)
|
||||
|
||||
1. Continue observe-only monitoring; re-sample load/memory in 15–30 minutes
|
||||
2. Prefer not running heavy builds / additional agents on this host until memory recovers
|
||||
3. Document findings in engagement vault (this report + memory sections)
|
||||
4. Escalate capacity concern to human operator
|
||||
|
||||
## 5. Escalation
|
||||
|
||||
- **Human operator (Bernd / railiance ops):** capacity (RAM/swap), whether k3s restart was intentional, approval for journal vacuum and package upgrades
|
||||
- **App owners:** Forgejo, activity-core, Temporal — if service degradation reported
|
||||
|
||||
## 6. Suggested inspect commands
|
||||
|
||||
```bash
|
||||
ssh railiance01 'free -h; uptime; cat /proc/pressure/memory'
|
||||
ssh railiance01 'sudo k3s kubectl get node; sudo k3s kubectl get pods -A | head'
|
||||
ssh railiance01 'sudo du -sh /var/log/journal'
|
||||
```
|
||||
|
||||

## Known quirks
|

|

- Single-node production: no HA; memory headroom is the binding constraint
|

- DinD / Actions runner privilege model (railiance-hosts ADR-004)
|
||||
- ops-bridge reverse tunnels to localhost ports (state-hub 18000/18001, etc.)
|
||||
- sshd journal noise: reverse-forward port 18765 already in use (tunnel contention)
|
||||
- Inventory hostname vs DNS: reverse DNS is HostEurope generic name

## OS & Patch State
|
||||
|
||||
_Pending first OS security pass (RU-05 / weekly protocol)._
|
||||
- Ubuntu 24.04.3 LTS (noble); kernel 6.8.0-87-generic (needrestart KSTA=1 — kernel current)
|
||||
- Many packages upgradable (security-relevant: bind9-*, curl, ca-certificates, dpkg, …)
|
||||
- `unattended-upgrades.service` flagged by needrestart for restart
|
||||
- **No package upgrades applied** this session (gated)
|
||||
|
||||
## Security Posture
|
||||
|
||||
_Pending first security snapshot (RU-05)._
|
||||
- UFW **active**: default deny in; allow OpenSSH 22, k3s API **6443/tcp Anywhere**, flannel **8472/udp Anywhere**
|
||||
- Listeners include SSH, k3s components, localhost bridge ports (18000/18001), gitea stack processes
|
||||
- Journal noise: reverse-forward port 18765 already in use (tunnel contention)
|
||||
- Public 6443 exposure: policy review recommended (firewall_change gated)
|
||||
- First snapshot: 2026-07-16 (see health report)
|
||||
|
||||
## Load & Workload Envelope

||||
| Field | Value (2026-07-16 sample) |
|
||||
|-------|---------------------------|
|
||||
| Cores | 2 |
|
||||
| Load 1/5/15 | ~12 / 11 / 16 (**saturated**) |
|
||||
| RAM | 3.8 GiB; no swap; MemAvailable often <0.5 GiB |
|
||||
| PSI memory full | avg60 ~24%, avg300 ~29% |
|
||||
| Disk / | 54% of 96G |
|

| /var/log | ~5.7G (journal ~4.1G) |
|
||||
| Heavy workloads | k3s server, gitea, temporal-server, activity-core worker/API, state-hub edge uvicorn, traefik, coredns |
|
||||
| Saturation incident | 2026-07-16 — memory+load critical; k3s API ServiceUnavailable |
|
||||
|
||||
**Envelope intent:** treat load > 4 sustained or MemAvailable < 300Mi as **Watch/Critical**; escalate capacity.
|
||||
|
||||
## Accumulated Findings
|
||||
|
||||
_None yet._
|
||||
- Undersized RAM for workload density is the dominant risk
|
||||
- k3s API instability under memory pressure
|
||||
- Large journald footprint
|
||||
- Pending OS security updates
|
||||
|
||||
## What Worked
|
||||
|
||||
_None yet._
|
||||
- Observe path via `ssh railiance01` (tegwick + id_custodian_agent)
|
||||
- passwordless `sudo -n` for read-only needrestart/ufw/k3s inspect
|
||||
- Engagement vault + close-session for durable evidence
|
||||
|
||||
## Watch Points
|
||||
|
||||
- Single-node production: privileged mistakes have full blast radius
|
||||
- DinD / Actions runner privilege model on railiance01 (see railiance-hosts ADRs)
|
||||
- DinD / Actions runner privilege model (railiance-hosts ADR-004)
|
||||
- Disk growth from images, logs, and backups
|
||||
- Do not schedule heavy CI/agents until memory recovers
|
||||
- Bridge reverse-forward port collisions (18765)
|
||||
|
||||
## Recurring Findings
|
||||
|
||||
_None yet._
|
||||
- Memory pressure / no swap · first seen 2026-07-16 · frequency 1
|
||||
- Load ≫ cores · first seen 2026-07-16 · frequency 1

## Cleared Issues

_None yet._
|
||||
_None yet (no remediation applied)._
|
||||
|
||||
## Open Threads
|
||||
|
||||
- Complete RU-01 access verification
|
||||
- Capture baseline `vault/baselines/railiance01.md`
|
||||
- First health + load review report
|
||||
- Human decision: add RAM and/or temporary swap
|
||||
- Human approval: journal vacuum; security package upgrades; UFW source restriction for 6443
|
||||
- Re-check k3s API health after memory improves
|
||||
- Align inventory hostname with kernel hostname / DNS naming

# RU-08 — Privileged action proposal (DRY RUN — not executed)
|
||||
|
||||
**Engagement:** eng-coulomb-railiance01-ho-001
|
||||
**Date:** 2026-07-16
|
||||
**Author:** host-operator (grok session)
|
||||
**Status:** proposal only — **no human approval recorded; no changes applied**
|
||||
|
||||
## Purpose
|
||||
|
||||
Prove the privilege gate path: agent may **propose** privileged work; execution requires recorded human approval.
|
||||
|
||||
## Proposed actions (optional, priority order)
|
||||
|
||||
### P1 — Emergency swap file (if OOM imminent)
|
||||
|
||||
| Field | Value |
|
||||
|-------|--------|
|
||||
| Class | `privileged_ops` |
|
||||
| Blast radius | Host-wide; disk for swapfile; may pause I/O briefly |
|
||||
| Rollback | `swapoff` + remove swapfile |
|
||||
| Command sketch | create 2–4G swapfile on root FS (exact steps only after approval) |
|
||||
| Risk | Disk wear; masks capacity problem |
|
||||
|
||||
### P2 — journald vacuum
|
||||
|
||||
| Field | Value |
|
||||
|-------|--------|
|
||||
| Class | `privileged_ops` |
|
||||
| Blast radius | Historical logs discarded |
|
||||
| Rollback | none (logs gone) |
|
||||
| Command sketch | `journalctl --vacuum-size=500M` |
|
||||
| Risk | Loss of forensic depth |
|
||||
|
||||
### P3 — Package security upgrades
|
||||
|
||||
| Field | Value |
|
||||
|-------|--------|
|
||||
| Class | `package_upgrade` |
|
||||
| Blast radius | Service restarts; possible brief downtime |
|
||||
| Rollback | package-specific; may need restore |
|
||||
| Command sketch | `apt-get update && apt-get upgrade` (or unattended security only) |
|
||||
| Risk | Regression on production single-node |
|
||||
|
||||
### P4 — Restrict UFW sources for 6443/8472
|
||||
|
||||
| Field | Value |
|
||||
|-------|--------|
|
||||
| Class | `firewall_change` |
|
||||
| Blast radius | May lock out nodes/agents if mis-scoped |
|
||||
| Rollback | re-add rules |
|
||||
| Risk | High on single-node misconfiguration |
|
||||
|
||||
