Failover Clustering Windows 2016/2019 – Installation and Configuration

Configuration and administration of the failover cluster

Contents

Cluster and role (service) administration is done using the MMC: Failover Cluster Manager.

In this part, I will present you in a general way this console.

1. Click on the chevron before the cluster name 1 to scroll through the available sections.

Roles

This part groups together all the services that are distributed by the cluster. Role administration is done here.

In the example below, we find all the virtual machines running on the Hyper-V cluster. The configuration is VM is made from this page by the Actions menu available to the left of the console.

Nodes

In this section, we see the server members of the cluster, with the ability to act on how to pause them for maintenance. It is also possible to add nodes to the cluster from this page.

Storages / Disks

This is where you manage the available storage for the cluster. We find the Quorum disk 1 that we configured at the beginning of the tutorial. In an S2D cluster it is here that we will also manage the physical disks.

Add a disk to the cluster

A regular operation on a Hyper-V cluster is adding disk.

1. Present a SAN LUN to all nodes in the cluster.

2. On one of the cluster nodes, open the disk manager, bring online, initialize, and format the disk.

3. From the disk section in the cluster console, click Add Disk 1 in the Actions section.

Ajout disque au cluster

4. If your disk is properly presented to the nodes and formatted, it should be displayed. Select 1 and click OK 2 .

Sélection du disque

5. The disk is now added to cluster 1 , for the moment it is available only for the owning node.

Disque ajouté

6. Right-click on the disk and click Add to shared volumes in cluster 1 .

Ajout du disque au volume partagé

7. Disk 1 is now shared for all nodes in the cluster. In the details of the disc, we find the mount point (C: ClusterStorageVolumeX) 2 . If we look at all the nodes we can access the disk via the explorer. Note also the disk format is now CSVFS (Cluster Storage Volume Files System).

Networks

The network management allows parameter communication between the clients and the cluster and the inter-node communication part. This is also where this setting the Live Migration as part of a Hyper-V cluster.

Réseaux du cluster de basculement

The properties of the network allow you to configure which communications pass over it.

Setting up dynamic migration

1. Click Dynamic Migration Parameter 1 accessible from the Actions menu.

Configuration live migration

2. Check the networks that can be used for the migration, if several networks are activated, configure the priority of use with the Up and Down buttons.

Configuration live migration

For networks to appear in this section, each node in the cluster must have an IP address in the configured network.

Load balancing for virtual machines

Since Windows 2016, it is possible to enable load balancing for virtual machines.

1. Right click on the cluster name 1 and click Properties 2 .

Configuration de load balacing

2. Go to the Balancer tab 1 and set the option according to your needs.

Config Load Balancing Hyper-V

The load-balancing is to be used with caution, because in an “overloaded” environment this can cause a large displacement of vm and impact the overall performance. It is also advisable not to enable this feature in a cluster of 2 nodes.

Change the IP address of the cluster

1. From the cluster main page in the Cluster 1 Main Resources section, scroll down the Name 2 part, right-click on the IP address 3 and click Properties < <4 .

IP du cluster

2. On the General tab, it is possible to change the network settings of the cluster.

Configuration IP du cluster

If you change the IP address of the cluster after it goes into production, consider reconfiguring the services that use it and the DNS records.
