We are trying to add new nodes to an existing Windows Failover Cluster (WFCS). When we run the Add Node wizard in Failover Cluster Manager, or run the Add-ClusterNode in PowerShell, we get the same cryptic error "The parameter is incorrect". No further information is provided in the cluster logs or any of the event logs.
The server 'servername' could not be added to the cluster. An error occurred while adding node 'servername' to cluster 'clustername'.
The parameter is incorrect
These are Windows 2012r2 servers.
