Cannot create Cluster – the computer X is joined to a cluster
Recently attempting to install a new three node cluster I ran into a new issue. Once I was able to run a successful “Cluster Validation Check” and chose the option to install a new cluster I received a message “The computer xxx is joined to a cluster”.
My first thought then was to remove clustering and try a fresh install of the feature. That didn’t go to well either, I was informed that the node was an active node of a cluster that it in fact was NOT.
I did a bit of research and found that I could clear this with using PowerShell. To do so I had to open PowerShell as an administrator and load the failoverclusters module. Then I could run the command clear-clusternode to forcefully clean up the cluster node.
Once the node was cleaned up I was able to proceed with the cluster build.

So do you know what triggered the original error. Were you going from a 2 node cluster to a 3 node cluster or something?
I haven’t been able to pinpoint the issue but I am leaning towards a GPO. Even after doing the fix, I didn’t create the cluster until the next day and the issue had come back. I had to run the PowerShell command again, built the cluster and so far so good. It has been a week.
Thank you! I was looking for the solution to this and your blog is the only thing that worked for me. Thanks again, Don
Powershell worked well with me.
Thanks for this. Lots of other sites only give the remove-cluster command where you need to know the cluster name. I am sure there is a simple way round that however this cut to the chase and gave the solution
Thank you, I was looking for a solution to this problem for many hours. Your solution took 5 seconds, much appreciated.
