Proxmox Cluster | Free Virtualization with HA Feature | Step by Step

    1. Cluster Configuration:
      • Nodes: A Proxmox cluster consists of multiple nodes, which are physical servers running Proxmox VE.
      • Networking: Nodes in a Proxmox cluster should be connected to a common network. A private network for internal communication and a public network for client access are typically configured.
      • Shared Storage: Shared storage is crucial for a Proxmox cluster to enable features like live migration and high availability. This can be achieved through technologies like NFS, iSCSI, or Ceph.
    2. High Availability (HA):
      • Proxmox VE includes a feature called HA, which ensures that critical VMs are automatically restarted on another node in the event of a node failure.
      • HA relies on fencing mechanisms to isolate a failed node from the cluster and prevent split-brain scenarios. This can be achieved through power fencing (e.g., IPMI, iLO, iDRAC) or network fencing (e.g., switch port blocking).
      • When a node fails, the HA manager on the remaining nodes detects the failure and initiates the restart of the affected VMs on healthy nodes.
    3. Corosync and Pacemaker:
      • Proxmox VE uses Corosync as the messaging layer and Pacemaker as the cluster resource manager. These components ensure that cluster nodes can communicate effectively and coordinate resource management.
      • Corosync provides a reliable communication channel between nodes, while Pacemaker manages the resources (VMs, containers, services) in the cluster and ensures they are highly available.
    4. Resource Management:
      • Proxmox clusters allow for dynamic resource allocation, allowing VMs and containers to use resources based on demand.
      • Memory and CPU resources can be allocated and adjusted for each VM or container, and live migration allows these resources to be moved between nodes without downtime.
    5. Backup and Restore:
      • Proxmox includes backup and restore functionality, allowing administrators to create scheduled backups of VMs and containers.
      • Backups can be stored locally or on remote storage, providing flexibility in backup storage options.
    6. Monitoring and Logging:
      • Proxmox provides monitoring and logging capabilities to help administrators track the performance and health of the cluster.
      • The web interface includes dashboards and graphs for monitoring resource usage, as well as logs for tracking cluster events.
    7. Updates and Maintenance:
      • Proxmox clusters can be updated and maintained using the web interface or command-line tools. Updates can be applied to individual nodes or the entire cluster.
