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.
I am trying to do the same thing (except add a 2016 server in) and get the same message. Haven't been able to find any logging of use that would show what the problem is. According to everything I can see it should be fine.
