Is it possible to create single node failover windows cluster

Hello,

I tried to create a single node windows 2109 failover cluster. The cluster creation was fine, however the disks were not listed to create fileserver role or to create any SMB share. Does it mean we have no way to create a single node cluster and work on it. This is just for testing environment. Any pointers would be of great help.

Thanks in advance for your help.

Thanks!

Hi @Priya-9505,

It is possible to create a Failover Cluster with only one (1) cluster node, however a failover cluster would typically have at least two (2) nodes in the cluster to allow resources to actually fail over between nodes in a planned or unplanned scenario.

It is also possible to add disks (you need to make sure they are shared disks), or cluster resources such as the File Server role and SMB shares.


If the reply was helpful please don't forget to upvote and/or accept as answer, thank you!


Best regards,
Leon

Thank you. It is good to know that in a single node cluster, things will work. However I don't see the disks show up to add to the cluster.

I do have the disks added to this node.

I am not sure what i am missing here.

In a single node, how can i make a disk shared.

The disks should come from a shared storage, for example a storage system or for example iSCSI.
Once the disks are shown in the Disk Management, you'll need to add the disks manually via the Failover Cluster Manager:

  1. Storage

  2. Right-click Disks

  3. Add Disk


Here's how to easily create a iSCSI Target server:

Hey,

As mentioned, you need shared storage to see it in Failover Cluster and configure it as CSV. As an example, you can use StarWind VSAN to create an iSCSI LUN and add it to your cluster. The following guide will help you with the configuration:
