CHAOS NIGHT round 6: I stopped a LEG, and the box carried on by itself
Correction to my own account, recorded where the wrong version stood. I wrote
"I stopped the backup". What I stopped was its LOCAL leg: the task list shows
that job ending 23:59:45 with status "job errors" - my pkill - while a second
vzdump was already running, streaming encrypted to ep0
(--repository felhom@pbs!tester-1@...:felhom-offsite --ns tester-1).

The arithmetic that forced the intervention still stands: the local leg was
writing a ~29GB source into a filesystem with 3.6GB free, falling at ~16MB/s,
which gave under four minutes before / filled and the nested PVE wedged - the
Phase 0 failure one level up. But the off-site leg needs no local space at all,
so the box's design copes with exactly the problem I thought I was rescuing it
from. It is still counted as an intervention: I reached in and killed a job.

The box then recovered unaided: 22 containers at 22:00:52Z, 26 at 22:01:13Z,
and / went from 2539MB free back to 7573MB once the partial archive was removed.
The older completed backup was left untouched.

Round 6's valuable half stands: during the backup 4 of 26 containers were up,
every app returned 404 through the public route, and NO alarm fired - the
suppression of the backup's own stack stops held.

And the waiting rule for the off-site leg is fixed in advance: round 7 does not
start while it runs, unless it is still running at 00:45, in which case round 7
proceeds and records that it cut an in-flight backup - labelled as that, not as
a clean internet-cut round.

Felhom — Documentation

Felhom is a managed home-server service for Hungarian households, built on a three-component model over Proxmox:

  • Hub — operator backend on k3s (hub.felhom.eu). Repo: felhom.eu/hub/.
  • Host agent — one per Proxmox host; operator-tier; owns all Proxmox interaction. Repo: felhom-agent/.
  • In-guest controller — one per customer LXC; Docker-only; manages the customer's apps. Repo: felhom-controller/.

This directory is the central, code-verified documentation home for all three components plus the platform and the security-audit record.

Sections

Controller (in-guest) — controller/

The Docker-only app-domain controller. Full per-area docs grounded in current source (v0.59.0). → controller/README.md: module map, deploy & stack lifecycle, backup architecture, storage/monitoring/metrics, auth/hub/sync/integrations.

Where we stand — architecture/where-felhom-stands.*

The operator's one-page picture of what is proven, built, partial and missing.

Host agent & platform — architecture/, proxmox-platform.md

The operator-tier agent and the Proxmox platform.

Hub (operator backend) — architecture/05

Security audits & remediation — audits/

Spike & test findings — tests/

Per-slice spike/validation findings (phases 0–5, slices 7–10). See tests/.

Conventions

  • Code-verified, not memory-derived. Architectural claims here are checked against the actual current source; if a claim can't be verified it is omitted and flagged, not guessed.
  • Per-repo operational working files (CLAUDE.md, CONTEXT.md, CHANGELOG.md, BUGHUNT.md, REPORT.md, TASK.md) live in their own repos — they are operational, not published docs.
  • Authoritative versions at last refresh: controller v0.59.0, agent v0.29.1, hub v0.11.0.
