High Availability
Ensure critical services survive hardware failures.
Work in Progress
This guide will cover configuring high availability in a Proxmox cluster.
What You'll Learn
- HA concepts: quorum, fencing, failover
- Enabling HA in a Proxmox cluster (minimum 3 nodes)
- Configuring HA groups and resource priorities
- Testing failover scenarios
- Which services to make highly available first
- HA for network services (dual DNS, redundant DHCP)
