Witness server issue in DAG
Posted on 2014-04-25
I am running into an issue which is don’t know what to do. Here is my situation. I have 4 member. Two DAG + witness server is on one network and 2 dag server in another network.
About 2 months ago I moved the Witness server to a new server:
Old server: ‘mmwitness’
New Witness: “License”
Using the command line I setup the Witness server:
Set-DatabaseAvailabilityGroup dag -WitnessServer licensesrv -WitnessDirectory c:\dag
I also made Exchange Trusted Subsystem member of local admin group.
Today we had a network issue and databases moved from one network to another, it really should not have. The reason it should not have moved because the 2 dag members plus witness resides on the same network. When I looked at the Failover cluster log I saw a surprising error. It said:
File share witness resource ‘File Share Witness (\\mmwitness.xxxxx.com\dag.xxxxxcom)’ failed to arbitrate for the file share ‘\\licensesrv.xxxxxx.com\dag.xxxxx.com’. Please ensure that file share ‘\\licensesrv.xxxxx.com\dag.xxxxx.com’ exists and is accessible by the cluster.
I do not understand why there is something in my dag setup that still pointing to my old which is mmwitness server. Why did I get this error?
Can you assist?
