+# HA Monitor cu PVE::Notify - versiune finală
+# Folosește sistemul nativ Proxmox cu template-uri personalizate
+#
+# TEMPLATE SYSTEM:
+# ================
+# Acest script folosește template-uri Handlebars pentru formatarea emailurilor,
+# exact ca sistemul de backup Proxmox. Template-urile trebuie create în:
+#
+# /etc/pve/notification-templates/default/
+# ├── ha-status-subject.txt.hbs    (subject-ul emailului)
+# ├── ha-status-body.txt.hbs       (conținutul text al emailului)
+# └── ha-status-body.html.hbs      (opțional, versiunea HTML)
+#
+# Template-urile folosesc sintaxa Handlebars cu variabilele:
+# - {{ hostname }}  : FQDN-ul serverului
+# - {{ status }}    : "SUCCESSFUL" sau "FAILED" 
+# - {{ runtime }}   : timpul de execuție în secunde
+# - {{ details }}   : detaliile verificării HA
+#
+# Pentru alte scripturi care vor să folosească sistemul de notificări Proxmox:
+# 1. Creați template-urile în /etc/pve/notification-templates/default/
+# 2. Folosiți PVE::Notify::notify($severity, $template_name, $template_data, $fields)
+# 3. $template_name trebuie să corespundă cu numele fișierelor template
+#
+# PREREQUISITE:
+# =============
+# Template-urile sunt create automat de script la prima rulare
+
+HOSTNAME=$(hostname)
+FQDN=$(hostname -f)
+DATE=$(date '+%Y-%m-%d %H:%M:%S')
+START_TIME=$(date +%s)
+
+# Funcție pentru crearea template-urilor de notificare
+create_templates() {
+    local template_dir="/etc/pve/notification-templates/default"
+    
+    # Creează directorul dacă nu există

+=== HOW TO READ pvecm status OUTPUT ===
+
+Your current problematic output shows:
+- Total votes: 2 (WRONG - should be 3)
+- Qdevice (votes 0) (WRONG - should be votes 1)
+
+After fix should show:
+- Total votes: 3 (CORRECT)
+- Qdevice (votes 1) (CORRECT)
+
+=== STEP-BY-STEP FIX ===
+
+Step 1 - Fix Qdevice (PRIORITY):
+   systemctl restart corosync-qdevice
+   sleep 5
+   corosync-qdevice-tool -s
+
+Step 2 - Verify cluster status:
+   pvecm status
+   LOOK FOR: Total votes: 3 (not 2!) and Qdevice (votes 1)
+
+Step 3 - Test HA functionality:
+   ha-manager status
+
+=== WHAT THIS MEANS ===
+QDEVICE DISCONNECTED: No tie-breaker vote
+- If one node fails, cluster may lose quorum
+- VMs won't automatically migrate
+
+The cluster works now but has no tie-breaker vote.
+One node failure = no quorum = VMs can't migrate.
+{{else}}
+All HA components are functioning normally.
+- Cluster has proper quorum with qdevice participation
+- Automatic VM migration is available
+- System is fully redundant
+{{/if}}
+
+=== MANUAL SCRIPT EXECUTION ===

+
+# Locația default: ~/.ssh/id_rsa
+# Apasă Enter pentru locația default
+# Setează parolă opțională pentru cheie
+```
+
+### 2. Copierea Cheii pe Proxmox
+```bash
+# Metoda automată
+ssh-copy-id root@10.0.20.201
+
+# Metoda manuală
+cat ~/.ssh/id_rsa.pub | ssh root@10.0.20.201 "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

+# Conectare cu debug
+ssh -v root@10.0.20.201
+
+# Test conectivitate
+ping 10.0.20.201
+```
+
+### Probleme VM Windows 11
+```bash
+# Bypass cerințe TPM/Secure Boot în setup
+reg add "HKLM\SYSTEM\Setup\LabConfig" /v "BypassTPMCheck" /t REG_DWORD /d 1 /f
+reg add "HKLM\SYSTEM\Setup\LabConfig" /v "BypassSecureBootCheck" /t REG_DWORD /d 1 /f
+reg add "HKLM\SYSTEM\Setup\LabConfig" /v "BypassRAMCheck" /t REG_DWORD /d 1 /f
+
+# Forțare cont local în OOBE
+oobe\BypassNRO.cmd
+```
+
+### Verificare Status Servicii
+```bash
+# Status servicii Proxmox
+systemctl status pveproxy
+systemctl status pvedaemon
+systemctl status pvestatd
+
+# Restart servicii dacă e nevoie
+systemctl restart pveproxy
+```

+- **Port:** 8006 (HTTPS)
+
+## Note Importante
+1. **Întotdeauna fă backup** înainte de modificări majore
+2. **Folosește storage local-zfs** pentru performanță optimă
+3. **Pentru Windows 11** folosește placa de rețea e1000 în loc de VirtIO pentru compatibilitate
+4. **CPU type 'host'** oferă performanțe maxime cu KVM=1
+5. **Testează conexiunea SSH** înainte de automatizări
