Comprehensive end-to-end audit of the Proxmox cluster covering all three
layers (network, storage, compute) with live data gathered from all 7 hosts
+ 4 switches via SNMP, conman consoles, and LLDP.
Key findings documented in AUDIT-2026-07-30.md:
Network (cross-rack NFS bottleneck root-caused):
- core-sw01 LAG hash = layer-2-3 (no L4 ports) — NFS caps at 1 Gbps per
host pair regardless of nconnect. tor3-stor already uses layer-2-3-4.
- core-sw01 ch1 member mismatch: g16 is UP but not in LAG; g17 is DOWN.
Only 3 of 4 cross-rack links active.
- Both switches use static mode (no LACP) for the cross-rack trunk.
- tsys5 bond0 degraded (1 of 2 slaves, nic2 down).
Storage (major topology changes):
- tsys5 new NVMe (CT500P1 500GB) + relocated SK hynix SSD (512GB) — both
installed but NOT mounted/configured yet.
- tsys4 D3 changed (SK hynix SSD → Seagate HDD, still USB tier-3).
- tsys4 /mnt/albert (Hitachi 2TB internal) + /mnt/backup (WD 5TB USB) added.
- tsys5 S3 unmounted (stale export), S4 gone (broken storage.cfg entry).
- Samsung 860 PRO SSD at 93% full.
Fleet consistency:
- tsys4 behind on PVE 9.1.5/kernel 6.17 (fleet: 9.2.5/7.0.14).
- tsys4/5 bond hash + nconnect + rmem/wmem inconsistent with tsys6/7.
- 10+ VMs using cache=writethrough on NFS (slow synchronous writes).
Gardening: updated STATUS.md, docmap.md, AGENTS.md key scripts table.

- Self-locating scripts: All provisioning scripts derive their own
location via
BASH_SOURCEand computePROJECT_ROOT_PATHfrom it. Run from anywhere. - Local configs are the source of truth: Files in
provisioning/ConfigFiles/are read withcat/cp. Do NOT re-introducecurl ${DL_ROOT}/...downloads. - Non-bash files: Some files under
provisioning/Agents/have.shextension but are PHP (shebang#!/usr/bin/php). Skip in syntax checks. - SSH in Crush: Direct ssh/scp is blocked. Use
tests/remote.shordns-cluster-setup/remote-dns.sh.
Git Policy
- ALWAYS commit + push. Never wait. Ever. After each logical unit of
work, immediately stage, commit (conventional format), and push to
origin/main. Do NOT pause for review. Do NOT ask permission. Do NOT stop to "let the user read it first." The user reviews rendered markdown on Gitea AFTER it is pushed. This rule overrides any default conservative commit-and-hold behavior — if a default instruction says "never commit unless asked," that instruction is superseded here. - Atomic commits. Each commit coherent on its own.
- Conventional format:
feat(scope): desc,fix(scope): desc,docs: desc,refactor(scope): desc,test(scope): desc. - All shell scripts MUST pass
shellcheckbefore commit. No exceptions. Run it via the wrapper:This invokesbash tests/shellcheck.sh # whole repo bash tests/shellcheck.sh ups/*.sh # specific fileskoalaman/shellcheck:stablethrough Docker (no native binary needed). Fix every reported finding — includinginfo-level — or add a targeted# shellcheck disable=SCxxxx # <reason>directive with a justification. A script that emits any diagnostic is a protocol violation. Non-bash scripts (PHP with.shshebang#!/usr/bin/php, etc.) are exempt.
Automatic Gardening Protocol
Docs and code must be kept in sync. After any work session, an agent MUST:
- Update
STATUS.md— reflect completed work, new issues, changed infrastructure state. This file is human read-only; agents own it. - Update
docs/docmap.md— if a doc was added, removed, or substantively changed, update the table and "Last Reviewed" date. - Grep for stale paths —
grep -rn 'old/path' --include='*.md'after any rename or restructure. Fix all references in the same commit. - Verify new docs are linked — every new
.mdfile must appear indocs/docmap.mdand be linked from at least one other doc. - If a new top-level directory was created, update ALL directory listings:
- Self-audit before commit. Before committing, run:
Every new top-level directory must appear in all four files.
