#601 moves to version october-2026-window (due Oct 31; Redmine API refuses start_date on update, recorded in the note), #608 = cgroup_parent wiring (the gateway starvation fix on 8 vCPU), #609 = Fri 2026-09-04 troubleshooting-only outage with the physical checklist. 💘 Generated with Crush Assisted-by: Crush:glm-5.2 [#602]

# NEXT — perf-opt closeout COMPLETE (2026-08-31 16:4x)
|
||
|
||
## Final state — nothing owed
|
||
- All guest tuning live and verified (see 16:04-16:15 pass below).
|
||
- Host flags live: ssd=1/discard (ROTA=0), iothread, onboot=1, startup
|
||
order=10, cpuunits 9000/50, ide2 gone.
|
||
- Net multiqueue: queues=4/2 now IN live qm config (staged 16:40 by crush
|
||
via ssh); activates at the next VM start — ONE reboot still owed, human-
|
||
timed: run ~/optimize/5-activate-multiqueue.sh whenever convenient
|
||
(kills crush sessions, ~4 min). Guest oneshot ukrrs-net-multiqueue
|
||
auto-runs ethtool -L on that boot.
|
||
- Gateway boot-race + live-restore endpoint loss: permanently fixed by
|
||
ukrrs-gateway-ensure unit (enabled, both lanes).
|
||
- Root cause of the 15:59 no-op: the script copy executed then predates the
|
||
queues= fix (silent same-value rewrite); current config verified correct.
|
||
|
||
## Verified live after the 16:01 bounce (all read-only from the guest)
|
||
- Disks: ROTA=0, discard 4K/1G on sda+sdb+sdc → ssd=1/discard=on ACTIVE ✅
|
||
- Kernel: bbr+fq, 16M socket buffers, dirty_bytes 1G/256M, min_free 384M,
|
||
aio 1M, inotify 512/1M, port range 10240-65535, slow_start_after_idle=0,
|
||
tcp_tw_reuse=1, THP=madvise, DefaultLimitNOFILE 65536 ✅
|
||
- Mounts /,/data1,/data2 = noatime; swap sda5 prio -2 unused ✅
|
||
- Units: all ukrrs slices + day/night + psi + builder-prune + thp units
|
||
installed and enabled; PSI textfile writing (16:06) ✅
|
||
- Docker: daemon.json fully live (live-restore, log caps 20m×3, 172.16/12
|
||
pools, metrics :9323); 21 containers up ✅
|
||
- Desktop: sddm autologin worked (Relogin=true), session alive on seat0/tty2,
|
||
greeter burn GONE ✅
|
||
- Gateway prod was DOWN at boot (bind race + live-restore endpoint loss) →
|
||
recovered via compose --force-recreate; /status = mode normal, serving ✅
|
||
|
||
## Nothing owed. Optional sanity check any time (crush can ssh now):
|
||
~/optimize/4-host-netcheck.sh
|
||
|
||
## Noted, no action taken
|
||
- mopac-demo/mcli fake containers: restart=no, exited at the first bounce,
|
||
left down (test stubs; your call).
|
||
- Prometheus/harness daemons not deployed here yet (that is OPT-9's wiring).
|
||
|
||
## HARDWARE SLIPPED TO ~OCT 2026 (ruling 2026-08-31)
|
||
- PRESUME 8 vCPU / 48G on this VM until the #601 window: interim fences
|
||
(accounts 3G/4.5G) and the daynight interim values ARE the operating
|
||
config; the commented post-upgrade block stays dormant.
|
||
- Gateway cpuset hard reservation (16-17) waits for the window → the
|
||
compose cgroup_parent wiring is THE starvation fix meanwhile (ticketed).
|
||
- q35 / 20 vCPU / 128G / GPUs / USB3 reseat / NFS-outage-for--02 all move
|
||
to the same October window (#601 → version october-2026-window, due
|
||
10-31; #606).
|
||
- Fri 2026-09-04 = #609: troubleshooting-only outage (USB SDR reseat +
|
||
zero-cost socket/PSU/BIOS checks). Host down ⇒ this VM down, auto-starts
|
||
via onboot=1; gateway auto-recovers (validated 2026-08-31).
