# Fase 3: Cluster Formation (Week 7-8)
|
|
|
|
Target: Formar cluster 2-node, HA, cleanup
|
|
|
|
## 3.1 Preparar server.descomplicar.pt como Node A
|
|
|
|
```bash
|
|
# APENAS apos Fase 2 100% validada
|
|
|
|
# Backup final completo
|
|
tar -czf /tmp/final-backup-server.tar.gz /etc /home /var/www
|
|
|
|
# Reformatar com Proxmox (/proxmox-setup)
|
|
# Tornar Node A do cluster
|
|
```
|
|
|
|
## 3.2 Cluster Formation
|
|
|
|
```bash
|
|
/proxmox-cluster create --node-a server.descomplicar.pt --node-b cluster.descomplicar.pt
|
|
```
|
|
|
|
## 3.3 HA Configuration
|
|
|
|
```bash
|
|
/proxmox-ha configure --critical-vms 200,300
|
|
```
|
|
|
|
## 3.4 Cleanup
|
|
|
|
```bash
|
|

## Backup Strategy Durante Migration
|
|
|
|
### Fase 1 (EasyPanel)
|
|
|
|
3 locais:
|
|
1. Containers em easy.descomplicar.pt (original)
|
|
2. PBS Node B backup
|
|
3. easy.descomplicar.pt VPS backup (mantido durante Fase 1)
|
|
|
|
### Fase 2 (CWP)
|
|
|
|
Safety net 7 dias:
|
|
1. Server antigo intacto (rollback rapido)
|
|
2. VM CWP -> PBS backups automaticos
|
|
3. Backups manuais /mnt/migration/
|
|
|
|
RPO: 1h (PBS backups hourly se critical)
|
|
RTO: 2-4h (restore + DNS propagation)
|
|
|
|
### Fase 3 (Cluster)
|
|
|
|
Redundancia completa:
|
|
1. VMs em Node A + Node B
|
|
2. PBS primary (Node B 16TB)
|
|
3. PBS secondary remote sync (Node A 12TB)
|
