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.
Superseded AUDIT-2026-07-29 as the authoritative audit.

# Agent Guidelines
|
|
|
|
**Top-level files:** [`README.md`](README.md) (project overview),
|
|
[`STATUS.md`](STATUS.md) (living status, agent-maintained),
|
|
[`docs/docmap.md`](docs/docmap.md) (documentation index). Everything else
|
|
lives in subdirectories.
|
|
|
|
## Repository Layout

|
|
```
|
|
|
|
- **Self-locating scripts**: All provisioning scripts derive their own
|
|
location via `BASH_SOURCE` and compute `PROJECT_ROOT_PATH` from it. Run
|
|
from anywhere.
|
|
- **Local configs are the source of truth**: Files in
|
|
[`provisioning/ConfigFiles/`](provisioning/ConfigFiles/) are read with
|
|
`cat`/`cp`. Do NOT re-introduce `curl ${DL_ROOT}/...` downloads.
|
|
- **Non-bash files**: Some files under `provisioning/Agents/` have `.sh`
|
|
extension but are PHP (shebang `#!/usr/bin/php`). Skip in syntax checks.
|
|
- **SSH in Crush**: Direct ssh/scp is blocked. Use
|
|
[`tests/remote.sh`](tests/remote.sh) or
|
|
[`dns-cluster-setup/remote-dns.sh`](dns-cluster-setup/remote-dns.sh).
|
|
|
|
## Git Policy
|
|
|
|
1. **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.
|
|
2. **Atomic commits.** Each commit coherent on its own.
|
|
3. **Conventional format**: `feat(scope): desc`, `fix(scope): desc`,
|
|
`docs: desc`, `refactor(scope): desc`, `test(scope): desc`.
|
|
4. **All shell scripts MUST pass `shellcheck` before commit.** No exceptions.
|
|
Run it via the wrapper:
|
|
```bash
|
|
bash tests/shellcheck.sh # whole repo
|
|
bash tests/shellcheck.sh ups/*.sh # specific files
|
|
```
|
|
This invokes `koalaman/shellcheck:stable` through Docker (no native binary
|
|
needed). Fix every reported finding — including `info`-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 `.sh` shebang `#!/usr/bin/php`, etc.) are exempt.
|
|
|
|
## Automatic Gardening Protocol
|
|
|
|
**Docs and code must be kept in sync.** After any work session, an agent MUST:
|
|
|
|
1. **Update [`STATUS.md`](STATUS.md)** — reflect completed work, new issues,
|
|
changed infrastructure state. This file is human read-only; agents own it.
|
|
2. **Update [`docs/docmap.md`](docs/docmap.md)** — if a doc was added,
|
|
removed, or substantively changed, update the table and "Last Reviewed"
|
|
date.
|
|
3. **Grep for stale paths** — `grep -rn 'old/path' --include='*.md'` after
|
|
any rename or restructure. Fix all references in the same commit.
|
|
4. **Verify new docs are linked** — every new `.md` file must appear in
|
|
[`docs/docmap.md`](docs/docmap.md) and be linked from at least one other
|
|
doc.
|
|
5. **If a new top-level directory was created, update ALL directory listings:**
|
|
- [`README.md`](README.md) → "Directory Structure" table
|
|
- [`AGENTS.md`](AGENTS.md) → "Repository Layout" code block
|
|
- [`AGENTS.md`](AGENTS.md) → "Key Scripts" table (if the directory has
|
|
an entrypoint script)
|
|
Missing any one of these is a protocol violation.
|
|
6. **Self-audit before commit.** Before committing, run:
|
|
```
|
|
grep -lE 'new_dir_name' README.md AGENTS.md docs/docmap.md STATUS.md
|
|
```
|
|
Every new top-level directory must appear in all four files.
|
|
|
|
