I have installed a 3-node SQL Server 2012 failover cluster on Windows Server 2012 few days ago, and it has been running very well. Until today, I found that I could not manually failover the SQL cluster service from node 3 to node 1, and failed with the following information:
The operation has failed
The action 'Move' did not complete
The operation failed because either the specified cluster node is not the owner of the group, or the node is not a possible owner of the group
Here is a screenshot:
The error is a bit strange to me as I can see the Node 1 was listed there when I performed the Move operation, and the cluster installation was successfully on all 3 nodes. At this point, I did some research, and found someone mentioned that the Node 1 might be not a possible owner for one or more of SQL Server failover cluster dependencies. After several clicks, I found that the failed Node 1 was not a possible owner of IP address of SQL Server virtual server name like below, once I selected it back, the failover succeeded.
Hope this helps 🙂
