# Fencing Configuration - Proxmox HA
|
|
|
|
Configuracao detalhada de fencing devices (STONITH) para High Availability.
|
|
|
|
---
|
|
|
|
## Opcao A: Watchdog (Software Fencing)
|
|
|
|
Mais simples, menos confiavel:
|
|
|
|
```bash
|
|
# Instalar watchdog em ambos nodes
|
|
apt install watchdog
|
|
|
|
# Load kernel module
|
|
modprobe softdog
|
|
|
|
# Auto-load on boot
|
|
echo "softdog" >> /etc/modules
|
|
|
|
# Configurar HA Manager para usar watchdog
|
|
# (automatico quando HA activado)
|
|
```
|
|
|
|
## Opcao B: IPMI/iLO (Hardware Fencing)
|
|
|
|
Mais confiavel, requer IPMI:
|
|
|
|
```bash
|
|
# Verificar IPMI disponivel
|
|
ipmitool lan print
|
|
|
|
# Configurar IPMI credentials (via BIOS ou ipmitool)
|
|
|
|
# Configurar em Proxmox (Web UI):
|
|
# Datacenter -> Fencing -> Add
|
|
# Type: IPMI
|
|
# IP: <node-ipmi-ip>
|
|
# Username: admin
|
|
# Password: <ipmi-pass>
|
|
|
|
# Test
|
|
fence_ipmilan -a <node-ipmi-ip> -l admin -p <pass> -o status
|
|
```
|
|
|
|
## Opcao C: Network Fencing (Menos Confiavel)
|
|
|
|
Usar apenas se IPMI nao disponivel:
|
|
|
|
```bash
|
|
# SSH-based fencing (perigoso)
|
|
# Depende de network estar up
|
|
# Nao recomendado para production
|
|
```
|
|
|
|
## Recomendacao Cluster Descomplicar
|
|
|
|
- **Inicio:** Watchdog (simple, funcional)
|
|
- **Producao:** IPMI se hardware suporta
|
|
- **Evitar:** Network fencing
