Full System Recovery: Recovering a Cluster on Windows Server 2008 and Later

You can recover a cluster on Windows Server 2008 clients in one of the following ways:

  • Restoring Cluster Services
  • Authoritative Restores
  • Non-Authoritative Restores

Restoring Cluster Services

On a Windows computers, the cluster services will be restored automatically in any of the following scenarios:

Situation

Corrective Action

Cluster files on witness disk/Quorum Disk) are corrupt
  • Files in the \Cluster directory will be re-created.
  • Cluster configuration will be ‘pushed’ to the Witness Disk

Cluster database (ClusDB) on a single node is missing or corrupt

Healthy nodes will be contacted and an updated ClusDB will be downloaded.

Complete loss of Witness Disk/LUN occurs
  • If using Disk Only quorum model you need to use /ForceQuorum recovery switch.
  • Use Cluster Quorum Wizard to change quorum disk designation.

Authoritative Restores

Perform the Authoritative Restore of cluster on Windows 2008 or later if you alter the cluster configuration or delete a large number of resources. You can perform the authoritative restore only if all cluster nodes and services are running.

Non-Authoritative Restores

A non-authoritative restore is performed in the following scenarios:

  • Single node in a cluster fails completely (no boot) and the shared disks are still functional
  • Complete loss of all nodes and storage

To restore the original cluster configuration, perform the following tasks:

  1. Rebuilding the Operating System
  2. Recovering Windows File System Data
