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)

Documenteaza incidentul Kingston SNV3S2000G hang la 2026-04-30 (Sensor 2
74°C → emergency mode + restart loop) si masurile aplicate: distantare
temporala backup-uri par/impar, mutare CT 101+110 pe pve1 backup-ssd,
nofail in fstab, hardware watchdog iTCO_wdt, monitoring CSV la 30 min.
Adauga scripturile /opt/scripts/kingston-thermal-{monitor,report}.sh
pentru tracking trend si alertare la depasirea pragurilor termale.

The DR test script used set -euo pipefail, so a failing SSH
shutdown command caused the script to exit before qm stop.
On 2026-04-20 this left VM 109 running for 2.5 days and
triggered an OOM cascade when pvemini HA-failed over to
pveelite.
Adds EXIT trap that force-stops VM 109 regardless of exit
path, and makes the Step 7 SSH shutdown tolerant of failure.
