Expanding cluster from two nodes to three-node+ cluster

Expanding cluster from two nodes to three-node+ cluster

  • Azure Stack HCI version 22H2 supports inline fault domain and resiliency changes for scaling-out Azure Stack HCI cluster from two nodes to three-node+ cluster.

    • The new node must be installed with an operating system same as the cluster. In this case, it should have Azure Stack HCI version 22H2 operating system.
    • Only two-way to three-way mirror volume resiliency is supported for cluster expansion.
    1. Create an Azure Stack HCI cluster with two nodes. Check the resiliency for volumes using the following command:Get-VirtualDisk | Select NumberOfDataCopies, FriendlyName
      To view the volume resiliency on the Windows Admin Center, select the cluster name and click Volumes > Inventory. All volumes must have a two-way mirror resiliency.


    2. Expand the cluster (add one (or more) new nodes) using the following command:Add-ClusterNode -Name <nodename>
    3. Convert the volume resiliency from two-way to three-way mirror using the following command:Set-VirtualDisk -FriendlyName <name> -NumberOfDataCopies 3
      After running this command, check the cluster name and click Volumes > Inventory. The volume status will show as Needs repair. You can also monitor the status by using the Get-StorageJob command on the nodes.


      After converting all the volumes:
