- 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

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

VM 201 (Windows critical) stays out of HA by design. Added:
- failover-vm201.sh: interactive failover pvemini -> pveelite with ZFS replication state
- recover-vm201-to-pvemini.sh: interactive reverse migration with uptime + split-brain checks
- pvemini-down-alert.sh: cron watchdog on pveelite, emails full runbook after 2min DOWN
Replication RPO tightened: CT 108 + VM 201 to 5min, CT 171 to 15min.
CT 171 added to HA (ha-group-main) for continuous Claude Code access.

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.

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.
