Run outputs moved to logs/ (incl. sda partition-table backup). New from the 15:57-16:03 parallel session: 16-grow-root-online.sh (RAN: / = 431G online, swap removed by design — GROW-ROOT-RUNBOOK superseded) and 15-docker-to-data2.sh (staged, not run). README/NEXT/RUNBOOK/REBUILD reflect current reality. Moot rdp-testprep timer removed from the VM. Details: https://projects.knownelement.com/issues/615

# Runbook 2026-08-31 — COMPLETE (amended after the Oct replan)
|
||
|
||
Steps 1-3 below all landed and were verified read-only the same day (see
|
||
REPORT.md status banner + §8, and NEXT.md). Kept for the record. Paths
|
||
updated: repo moved ~/optimize → ~/projects/ultix.
|
||
|
||
**Remaining perf actions (as of 2026-09-01):**
|
||
1. Net multiqueue — DONE + verified 2026-09-01 morning (bounce
|
||
22:51->22:53; `ethtool -l` ens18 4/4, ens19 2/2).
|
||
2. ~~Root growth~~ DONE ONLINE 2026-09-01 16:03 by a parallel crush
|
||
session: `16-grow-root-online.sh` — / is 431G, swap removed by design,
|
||
no reboot needed (sfdisk backup in logs/ + /root/). #603 satisfied.
|
||
3. Rebuild-from-scratch path documented: REBUILD.md + docs/state
|
||
snapshots (regen: 14-capture-state.sh) — #615.
|
||
|
||
**Friday 2026-09-04 (#609) is TROUBLESHOOTING-ONLY**: USB SDR reseat +
|
||
zero-cost socket/PSU/BIOS checks. NO CPU/RAM swap, NO upgrades. All hardware
|
||
moved to the ~Oct 2026 window (#601: 2× X5675 + 6× 16GB → 192G; NFS outage
|
||
for -02 planned first; then q35 + 20 vCPU/128G + GPUs #606). Until then the
|
||
interim fences (accounts 3G/4.5G) and daynight interim values ARE the
|
||
operating config.
|
||
|
||
Original steps, for the record:
|
||
1. `sudo ~/projects/ultix/1-guest-prep.sh` — kernel tunables, BBR, THP,
|
||
cgroup slices, PSI collector, day/night timers, docker daemon.json, sddm
|
||
autologin. DONE + verified.
|
||
2. `ssh root@pfv-tsys5.knel.net 'bash -s -- --go' <
|
||
~/projects/ultix/2-host-one-shot.sh` — graceful stop of 5111,
|
||
ssd/discard/multiqueue-config/onboot flags, cpuunits 9000 over the
|
||
sectestbed fleet, start 5111. DONE + verified (16:01 bounce).
|
||
3. Verification — DONE (16:04-16:15 pass). Follow-up root cause: gateway
|
||
prod was DOWN at boot (bind race + live-restore endpoint loss);
|
||
permanently fixed same day by the ukrrs-gateway-ensure unit, both lanes.
|
||
|
||
Rollback notes unchanged: apply-guest backs up every file it touches; qm
|
||
flags are individually reversible.
