I am creating a fail over cluster, but doing so i get the error "An error occurred while creating the cluster. An error occurred creating cluster 'testCluster'.

This operation returned because the timeout period expired " Moreover following is my setup: Node 1: SQLA Node 2: SQLP

I have created two Server with server 2012 OS. SQLA machine is the domain and has 3 iSCSI Targets configured in it. SQLP and SQLA is the initiators (Client). Moreover I ran the validation and tried creating cluster on SQLA machine.

I have attached the screen shots of Validations and Cluster Creation failure. Kindly suggest if i am missing anything in doing this activity.


  • "SQLA machine is the domain" - can you explain what you mean by that? Do you mean SQLA is a domain controller? – Todd Wilcox May 18 '16 at 13:35
  • yes Exactly SQLA machine is a domain controller – Sabih Ahmed Khan May 19 '16 at 9:12

Running Domain Services on a cluster node was always a bad thing to do, but it was possible in certain configurations.

Unfortunately this has changed with Windows 2012, and Windows 2012-R2.

Running a domain controller on a node, or trying to add a node running domain services to a cluster will no longer work.

This is documented here: KB 2795523

Your solution is to run Domain services on a separate host, not on a cluster node.
