How to create a Failover Cluster in Windows Server 2019

This article gives a short overview of how to create a Microsoft Windows Failover Cluster ( WFC ) with Windows Server 2019 or 2016. The resultant role will be a two-node bunch with one shared harrow and a bunch calculate resource ( computer object in Active Directory ) .


It does not matter whether you use forcible or virtual machines, barely make sure your technology is desirable for Windows clusters. Before you start, make sure you meet the watch prerequisites :
Two windows 2019 machines with the latest updates installed. The machines have at least two network interfaces : one for production traffic, one for cluster traffic. In my exercise, there are three network interfaces ( one extra for iSCSI traffic ). I prefer static IP addresses, but you can besides use DHCP.

Join both servers to your Microsoft Active Directory domain and make sure that both servers see the shared memory device available in disk management. Don ’ t bring the disk on-line so far .
The future dance step before we can truly start is to add the Failover clustering feature ( Server Manager > add roles and features ) .

Reboot your server if required. As an option, you can besides use the following PowerShell command :

Install-WindowsFeature -Name Failover-Clustering –IncludeManagementTools

After a successful facility, the Failover Cluster Manager appears in the start menu in the Windows Administrative Tools .
After you installed the Failover-Clustering feature of speech, you can bring the divided harrow on-line and format it on one of the servers. Don ’ metric ton deepen anything on the second server. On the second server, the magnetic disk stays offline .
After a refresh of the magnetic disk management, you can see something alike to this :
server 1 Disk Management ( harrow condition online )

server 2 Disk Management ( disk condition offline )

Failover Cluster facility see

Before we create the bunch, we need to make certain that everything is set up by rights. Start the Failover Cluster Manager from the begin menu and scroll down to the management department and chatter Validate Configuration .

Select the two servers for validation .

Run all tests. There is besides a description of which solutions Microsoft supports .

After you made certain that every applicable test passed with the condition “ successful, ” you can create the bunch by using the checkbox Create the cluster now using the validated nodes, or you can do that by and by. If you have errors or warnings, you can use the detail report by clicking on View Report .

Create the failover bunch

If you choose to create the bunch by clicking on Create Cluster in the Failover Cluster Manager, you will be prompted again to select the cluster nodes. If you use the Create the cluster now using the validated nodes checkbox from the bunch establishment charming, then you will skip that step. The adjacent relevant step is to create the Access Point for Administering the Cluster. This will be the virtual object that clients will communicate with late. It is a calculator object in Active Directory .
The ace asks for the Cluster Name and IP address configuration.

As a last measure, confirm everything and wait for the bunch to be created .

The charming will add the share disk mechanically to the bunch per nonpayment. If you did not configure it however, then it is besides potential afterwards .
As a resultant role, you can see a new Active Directory calculator object named WFC2019 .

You can ping the new calculator to check whether it is on-line ( if you allow ping on the Windows firewall ) .

As an option, you can create the bunch besides with PowerShell. The follow command will besides add all eligible storage automatically :

New-Cluster -Name WFC2019 -Node SRV2019-WFC1, SRV2019-WFC2 -StaticAddress

You can see the result in the Failover Cluster Manager in the Nodes and Storage > Disks sections .

The word picture shows that the harrow is presently used as a quorum. As we want to use that disk for data, we need to configure the quorum manually. From the cluster context menu, choose More Actions > Configure Cluster Quorum Settings .

here, we want to select the quorum witness manually .

presently, the bunch is using the disk configured early as a disk witness. alternative options are the file parcel witness or an azure storehouse report as witness. We will use the file share witness in this exemplar. There is a bit-by-bit how-to on the Microsoft web site for the cloud witness. I always recommend configuring a quorum witness for proper operations. then, the stopping point option is not truly an option for production .

good point to the path and finish the charming .

After that, the shared disk is available for use for data .

Congratulations, you have set up a Microsoft failover bunch with one shared disk .

future steps and backup

One of the following steps would be to add a character to the cluster, which is out of oscilloscope of this article. deoxyadenosine monophosphate soon as the bunch contains data, it is besides clock time to think about backing up the bunch. Veeam Agent for Microsoft Windows can back up Windows failover clusters with partake disks. We besides recommend doing backups of the “ entire system ” of the bunch. This besides backs up the operational systems of the bunch members. This helps to speed up repair of a fail bunch node, as you don ’ t need to search for drivers, etc. in case of a regenerate .
