LXC 110 (moltbot) a picat dupa un OOM local containerului urmat de reboot:
tailscaled a ramas delogat, iar containerul mostenea resolv.conf-ul Tailscale
de la host-ul pve1 (doar MagicDNS 100.100.100.100) -> rezolutie DNS zero desi
L3 era functional -> echo-core in crash-loop pe telegram.error.TimedOut.
Fixuri aplicate:
- pct set 110 --nameserver '10.0.20.1 1.1.1.1' (elimina dependenta de Tailscale)
- zram-tools pe pve1 (8G zstd, prio 100) - `swap: 4096` din config era fictiv,
host-ul nu avea niciun swap; root pe ZFS deci zram, nu swapfile
- MemoryHigh/MemoryMax pe pocket-tts + supertonic-tts - toate serviciile user
rulau cu limite `infinity`, de unde OOM-uri recurente (Apr 25, May 28 x4)
cu victime aleatorii alese dupa oom_score_adj
Documentatie:
- nou post-mortem in cluster/incidents/, adaugat in indexuri
- README lxc110: host corectat pveelite -> pve1 (+ RAM/CPU/storage reale),
comenzile pct redirectionate spre nodul corect
- README lxc171: tabel cu starea swap pe cele 3 noduri (pveelite are zvol,
nu zram - nu necesita acelasi fix)

- Proxmox default-matcher acum trimite doar la mail-to-root (pve1 smtp
eliminat din matcher → fix emailuri duble pentru backup/vzdump)
- Adaugat tabel cron jobs per nod cu motivul redirect-ului > /dev/null
- Regula: scripturi cu propriile notificari trebuie sa aiba redirect in
crontab, altfel cron genereaza email suplimentar de confirmare

Following the 2026-04-20 cluster outage, the cluster README now covers
HA resource limits, corosync token tuning (10s tolerance for USB glitches),
rasdaemon/netconsole/kdump diagnostic stack on pvemini, mail relay via
mail.romfast.ro with SMTP auth, OOM alerting via cron, and swap on pveelite.
VM 109 README now clearly states it was removed from HA and is only
started by the weekly DR test script.
