# 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

=== 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
|
||||||
|

||||||
|
|
||||||
|
=== MANUAL SCRIPT EXECUTION ===
|
||||||
|
|
||||||
|
To run this HA status check manually:
|
||||||
|
|
||||||
|
Basic check:
|
||||||
|
/opt/scripts/ha-monitor.sh
|
||||||
|
|
||||||
|
Verbose output (shows details on console):
|
||||||
|
/opt/scripts/ha-monitor.sh -v
|
||||||
|
|
||||||
|
Recreate email templates:
|
||||||
|
/opt/scripts/ha-monitor.sh --create-templates
|
||||||
|
|
||||||
|
Script location: /opt/scripts/ha-monitor.sh
|
||||||
|
Log file: /var/log/pve-ha-monitor.log
