Error

type 1 :

"This server is an active node in a failover cluster. Uninstalling the Failover CVlustering feature on those node may impact the availability of clustered service and applications. It is recommended that you first evict the server from cluster membership. This can be done through the Failover Cluster Management snap-in by expanding the console tree under Nodes, selecting the node, clicking More Actions, and then clicking Evict.

Note: But in actual you don’t see any cluster node in the fail over console

 

Type-2

when you are active node, and when you try to add the second node in the cluster , it will not add and it will state that “ the other node is already a cluster “

 

Resolutions

Deletion of node (which are hung or hidden) with PowerShell

PS :

(Type 1st command )   PS :Import-Module FailoverClusters

when you click enter  you will see nothing

then give this command “clear-clusternode”

it will ask you to choose yes or no > choose “Yes”  PRESS “Enter”

 

Note : Make sure you run the PowerShell in admin mode.
