create cluster fails Win2016.

  • I'm installing a cluster prior to my 2019 SQL build.


    Failover Cluster tools are installed on all nodes, validation succeeds, hosts are found, cluster create begins.  I can see that the procedure creates my cluster object in AD, the cluster service starts up and then.  It all fails & rolls back.


    Nothing in event view.  c:\windows\cluster\reports\createCluster.htm.

    Waiting for notification that the clsuter service on node XX has started ...

    Forming cluster 'XYZ'

    Operation failed, attempting cleanup.

    An error occurred while creating the clsuter and the nodes will be cleaned up.


    There was an error cleaning up the cluster nodes.  Use Clear-ClusterNode to manually clean up the nodes.


    Not sure where else to look for clues / what the issue might be.  Pointers are gratefully received.




  • My best guess is permissions or firewall. I imagine there is another log somewhere (windows event log for example) that contains more information about why it failed.

    Looks like something is also busted with the cluster cleanup, so may not hurt to run that process manually as indicated in the log.

    As a weird thought, are ANY of the nodes in the cluster already part of another failover group?

    The above is all just my opinion on what you should do. 
    As with all advice you find on a random internet forum - you shouldn't blindly follow it.  Always test on a test server to see if there is negative side effects before making changes to live!
    I recommend you NEVER run "random code" you found online on any system you care about UNLESS you understand and can verify the code OR you don't care if the code trashes your system.
