I have encountered an issue post SP1; when I try and add a 3rd mbx server into an existing DAG I get the following;
There was a problem changing the quorum model for database availability group DagName. Error: An Active Manager operation failed. Error: An error occurred while attempting a cluster operation. Error: Cluster API '"DeleteClusterResource() failed with 0x1389. Error: The operation cannot be completed because other resources are dependent on this resource"' failed..

I have logged a call with MS and they believe it relates to the cluster IP having a dependency on the File Share Witness; i.e. the cluster IP should have NO dependencies (the cluster name has no dependencies either.)
Do any of you have a 3 node DAG? And if so can you confirm / deny if you have a dependency listed under the DAG IP address?
Any help would be appreciated.
Once MS confirm there findings I will update the post.
Thanks in advance
