Configuring cloud witness in Windows Server 2016 Cluster Azure Files #cloud #azure #winserv   7 comments

Cloud Witness is a new type of Failover Cluster quorum witness being introduced in Windows Server 2016. But you will need an Azure Subscription to use this unless you are using your own private cloud to use a file share witness in a third  DataCenter. As this post is an edited post but still actual

Earlier I create a blog post about creating a file share in Azure.

But now this file share can also be used for your Private Cluster Or Azure Cluster but remember your cluster needs internet access to connect to Microsoft Azure.

So if you want to have a file witness then you will need the fileshare option but the cloud witness is using the BLOB storage and will cost you almost noting with Azure Credits

However the File share is still in preview under Windows Azure Files  http://msdn.microsoft.com/en-us/library/azure/dn167006.aspx

Sign up for a preview http://azure.microsoft.com/en-us/solutions/storage-backup-recovery/

Now that we have created a new storage account We can use this for the cluster.

If you select the storage account you will see something like this.

We are using the blob storage and skip the above but you can use this for other things

At the bottom you can select the Manage Access Keys. This is the information we needed for the cluster.

Keep this save ! You will need this in your cluster.

When opening my windows Cluster Failover manager under more actions you can configure the quorum settings.

As always we do the Advance configuration.

Now we check the Cloud Witness option.

We use the Account name and the Key from the Azure portal that we created earlier.

The screen may differ as you could have a different version!

And we have a Cloud Witness here configured in my Public Cloud.

We don’t need a site to site VPN just connect the Cluster nodes to Internet ( atleast a Azure connection )

image

If we check the Azure Configuration and there you can see the creation of MSFT-Cloud-Witness. With the files in the blob storage.

 

 

You can also configure this in azure.

With the Get-ClusterQuorum we find quickly what witness we have.

and Configuring this is also quickly done put your account name and key in the set-clusterquorum and it will create a Cloud Witness.

Set-ClusterQuorum -AccessKey V7CR1/DijezGyA== -AccountName clusterw10 –CloudWitness

Happy clustering
