Operator reported 4 vCPU / 16 GiB; verify shows guest still 2 / 3.8 GiB after recent reboot. Document check report and keep open thread until nproc/free match the new flavor.

# Capacity upgrade check — railiance01 — 2026-07-16
|
||
|
||
**Engagement:** eng-coulomb-railiance01-ho-001
|
||
**Operator report:** VM upgraded to **4 vCPU / 16 GiB RAM**
|
||
**Agent verify:** observe via `ssh railiance01`
|
||
|
||
## Result: not yet visible in the guest OS
|
||
|
||
| Resource | Operator target | Live guest (`/proc`, `lscpu`) |
|
||
|----------|-----------------|------------------------------|
|
||
| vCPU | 4 | **2** (`nproc` / `lscpu`) |
|
||
| RAM | 16 GiB | **~3.8 GiB** (`MemTotal` ≈ 4009884 kB) |
|
||
| Swap | (our /swapfile) | 4 GiB file, ~300 Mi used |
|
||
| Uptime at check | — | ~12 minutes (recent reboot) |
|
||
| Hypervisor | — | KVM / OpenStack Nova (ConfigDrive) |
|
||
| k3s node | — | **Ready** |
|
||
|
||
## Guest health snapshot (at check)
|
||
|
||
- Load ~2 on 2 cores (much better than Critical era load ~12)
|
||
- MemAvailable ~0.9 GiB; PSI memory full avg60 ~0.2% (comfortable **for current size**)
|
||
- Swap lightly used (~300 Mi)
|
||
|
||
So the **workload is calmer after reboot**, but the **instance size has not expanded** to 4/16 from the kernel’s point of view.
|
||
|
||
## Likely causes
|
||
|
||
1. Resize still pending or applied to a different VM/instance
|
||
2. Provider resize requires a further console action / hard reboot after flavor change
|
||
3. Resize failed partially (boot on old flavor)
|
||
4. Wrong host checked (we used SSH host alias `railiance01` → 92.205.62.239)
|
||
|
||
## Recommended operator steps (provider / OpenStack)
|
||
|
||
1. Confirm in HostEurope / OpenStack console that **this** instance (IP 92.205.62.239) shows flavor **4 vCPU / 16 GiB**
|
||
2. If resize is `VERIFY_RESIZE` / confirm-pending, **confirm** it
|
||
3. Hard reboot if the panel says so after resize
|
||
4. Re-check from shell:
|
||
|
||
```bash
|
||
ssh railiance01 'nproc; free -h; lscpu | grep -E "CPU\\(s\\)|Model"'
|
||
# expect: CPU(s): 4 and Mem ~15–16Gi
|
||
```
|
||
|
||
5. Optional later: reduce reliance on 4 Gi swapfile once 16 Gi is confirmed stable (keep small swap as cushion, or leave as-is)
|
||
|
||
## Agent action
|
||
|
||
- Vault/baseline **not** updated to 4/16 until live numbers match
|
||
- Open thread retained: “confirm capacity upgrade applied to guest”
