In this blog, I will be giving an overview of the new features in Windows Server Failover Clustering. Some of these will be talked about at the upcoming Windows Server Summit. That is another blog for another time.
Affinity is a rule you would set up that establishes a relationship between two or more roles i,e, virtual machines, resource groups, and so on to keep them together. AntiAffinity is the same but is used to try to keep the specified roles apart from each other.
In previous versions of Windows Server, we only had AntiAffinity capabilities. We took a look at what we were doing and made it better. Now, not only do we have AntiAffinity, but also Affinity. The below doc discusses the feature in more detail including how to configure it. For those that still use AntiAffinityClassNames, we will still honor it. Which means, upgrading to Windows Server AutoSites is basically what is says.
When you configure Failover Clustering, it will first look into Active Directory to see if Sites are configured. For example:. If they are and the nodes are included in a site, we will automatically create site fault domains and put the nodes in the fault domain they are a member of.
For example, if you had two nodes in a Redmond site and two nodes in a Seattle site, it would look like this once the cluster is created. As you can see, we will create the site fault domain name the same as what it is in Active Directory.
If sites are not configured within Active Directory, we will then look at the networks to see if there are differences as well as networks common to each other. For example, say you had the nodes with this network configuration:.
We will see this as multiple nodes in one subnet and multiple nodes in another. Therefore, these nodes are in separate sites and it will configure sites for you automatically. With this configuration, it will create the site fault domains with the names of the networks. This will make things easier when you want to create a stretched Failover Cluster. Since we just mentioned Storage Spaces Direct, one of the talked about features of it is repair.
As a refresher, as data is written to drives, it is spread throughout all drives on all the nodes. When a node goes down for maintenance, crashes, or whatever the case may be, once it comes back up, there is a "repair" job run where data is moved around and onto the drives, if necessary, of the node that came back.
A repair is basically a resync of the data between all the nodes. Cluster and pool quorum. Using guest virtual machine clusters with Storage Spaces Direct. Prestage cluster computer objects in Active Directory Domain Services. Configuring cluster accounts in Active Directory. Manage the quorum and witnesses.
VM load balancing. Cluster sets. Cluster operating system rolling upgrades. Upgrading a failover cluster on the same hardware. November 28, at am Reply. I am not able to understand, from where this IP address comes at the time of myclsuter. This is IP of primary or secondary machine. It is confusing me.

The passive node will be offline until a failover occurs. January 9, at pm Reply. It was throwing this error: Error in Validation. The argument is null or empty string. Parameter name: domainName It took me about 45 mins of digging around to find out that the DNS Suffix for my domain was empty. February 14, at pm Reply. February 27, at pm Reply. Any update on this?
