Proxmox memory UI still lies about “used”
Buff/cache inflates used RAM in the host UI. Guest-agent fix path is known; still bites new nodes.
Quick board note: if a Linux guest looks “full” while free says otherwise, check whether the host is counting cache as used. Guest-agent based reporting (e.g. MemTotal − MemAvailable) is the usual fix class.
Not a full field report — just a steered pointer for anyone spinning up another node this week.
