# ultix-streaming optimization — tracking HUD

One table, updated in place at each checkpoint. States: done ✅ / doing 🔄 / blocked ⛔ / next ⏳

||
| id | lane | state | item |
|
||
|---|---|---|---|
|
||
| OPT-1 | guest | ✅ | recon: system + ukrrs fleet (REPORT §1) |
|
||
| OPT-2 | guest | ✅ | REPORT.md + staged configs + questions-v1.md |
|
||
| OPT-3 | host | ✅ | audit parsed → REPORT §8 (T7500, CPU2 empty, clean IOMMU, Q4000 skip) |
|
||
| OPT-4 | host | ⏳ | Fri 2026-09-04 #601: 2× X5675 + 6× 16GB → 24T/192G (NFS outage for -02 first; USB3 reseat; q35/20c/128G) |
|
||
| OPT-5 | host | ✅ | one-shot landed + verified post-reboot; net multiqueue now in qm config (live at Friday's start) |
|
||
| OPT-6 | guest | ✅ | guest prep applied + verified (bbr, THP, slices, timers, noatime, daemon.json, autologin) |
|
||
| OPT-7 | guest | ⏳ | #603: root growth MANUAL ONLY, GROW-ROOT-RUNBOOK.md, user-executed |
|
||
| OPT-8 | repos | ✅ | PMO backpressure design note in ukrrs/docs/harness; code = ticketed |
|
||
| OPT-9 | integ | ⏳ | #604: node_exporter svc + gateway pressure scrape (Q10) |
|
||
| OPT-10 | integ | ⏳ | #605: k8s join (Q11, blocked by #601) + proxmox-ctl token (Q12); GPUs #606 |

Decisions log (latest wins):
|
||
- 2026-08-31 16:5x: Redmine = record: perf pass + RCA filed as #602 (project 55, tracker Support, left New for human review); open items #601 (Fri window, Urgent, due 09-04) #603 root growth #604 metrics #605 k8s+proxmox (blocked by #601) #606 GPUs (relates #601). mred = docker exec wrapper (~/.local/bin/mred → mopac-cli-mred container).
|
||
- 2026-08-31 16:40: net multiqueue CLOSED: queues=4/2 written to live qm config via crush ssh (user authorized non-disruptive host mods); activates at next VM start; guest oneshot enables channels on that boot. Earlier silent no-op explained: the 15:59 run used a pre-fix script copy.
|
||
- 2026-08-31 16:3x: crush CAN ssh to the host from this workspace (old "hard-banned" note obsolete); still human-gated for disruptive ops.
|
||
- 2026-08-31 (post-reboot validation): prod gateway down at boot ROOT-CAUSED twice over: (a) port bind to tailscale IP lost the dockerd-vs-tailscaled race (docker never retries failed starts), (b) live-restore dropped the container's network endpoint (host resolver → gateway-db unresolvable → crash loop). Recovered via compose --force-recreate (healthy, mode=normal). Permanent fix staged: ukrrs-gateway-ensure unit, BOTH lanes, MUST be enabled before Friday's bounces.
|
||
- 2026-08-31: multiqueue host flags verified live (ROTA=0 + discard 1G on all 3 disks), but guest still runs 1 queue/NIC: ethtool not installed; 3-post-reboot-fixes.sh staged (installs ethtool + oneshot unit, sets 4/2 queues).
|
||
- 2026-08-31: mopac-demo/mcli fake containers left DOWN (restart=no, exited at first bounce); prometheus/harness daemons not deployed on this box (pre-existing; belongs to OPT-9).
|
||
- 2026-08-31: STORAGE OPS MANUAL ONLY: boot-time auto-grow service removed, qm resize removed from the one-shot, grow-root.sh deleted. Runbook = GROW-ROOT-RUNBOOK.md, every command typed by the human.
|
||
- 2026-08-31: KDE autologin into UNLOCKED always-alive session (Relogin=true); autolock OFF (instant Jump/iPad attach outranks lock). XFCE only if Sunshine capture disappoints post-GPU.
|
||
- 2026-08-31: streamlined to 1-guest-prep.sh + 2-host-one-shot.sh (one reboot wave; no post-reboot steps; no storage).
|
||
- 2026-08-31: constraint: host pfv-tsys5 NEVER reboots casually (NFS server for -02); Friday CPU swap needs a planned NFS outage first.
|
||
- 2026-08-31: GPUs are COMPUTE cards; Quadro 4000 skipped (Fermi: no NVENC, no kernel-6 driver, no modern CUDA); clean IOMMU groups verified.
|
||
- 2026-08-31: day/night = runtime-only cgroup flips 22:00/05:00; NO cpufreq driver exists host or guest.
|
||
- 2026-08-31: zram rejected; no docker data-root move; skip tuned (sysctl.d + units).
|
||
- 2026-08-31: second USB3 SDR card missing on host (only one Renesas visible); Friday reseat/check.
