Hi All

I hope you can help.

I have a 3 node setup of Exchange 2010

Prod site = 1 x HUB, 1 x CAS,Mailbox

DR Site = 1 x Hub, CAS, Mailbox

Today my Prod Mailbox server was restarted and afterwards wouldnt mount its one database.  Initially after running ESEUTIL, it had a state of Dirty Shutdown.  I ran through a procedure detailed in msexchangeguru.com which allowed me to check the logs, check the health of the logs and then perform a Soft Recovery, after that point I was able to show a Clean Shutdown, but still wasnt able to Mount the Database.

I then proceeded to move the log files from the Transaction folder in the hope that now having a Clean Shutdown this would resolve the issue, but it hasnt.  here is the current error I am receiving when I right click and try to mount:-

--------------------------------------------------------
Microsoft Exchange Error
--------------------------------------------------------
Failed to mount database 'Mailbox Database 0505228569'.

Mailbox Database 0505228569
Failed
Error:
Database 'Mailbox Database 0505228569' can't be mounted on server 'SERVERNAME' due to a previous error: Failed to determine the mount status of the active database copy. Verify that the underlying cause of the error has been corrected before attempting to mount the database. The error can be ignored and the mount allowed if Mount-Database is reissued with the -Force switch.




--------------------------------------------------------
OK
--------------------------------------------------------

In EMS I get this:-

Couldn't mount the database that you specified. Specified database: Mailbox Database 0505228569; Error code: An Active
Manager operation failed. Error An Active Manager operation encountered an error. To perform this operation, the server
 must be a member of a database availability group, and the database availability group must have quorum. Error: Automo
unt consensus not reached..

I had a DAG previously, but now it only contains the CAS, Mailbox server on the Prod site so in effect its a single node DAG.  Running test-replication shows:-

Server          Check                      Result     Error
------          -----                      ------     -----
SERVERNAME         ClusterService             Passed
SERVERNAME         ReplayService              Passed
SERVERNAME         ActiveManager              *FAILED*   Active Manager is in an unknown state on server 'SERVERNAME'. Bas...
SERVERNAME         TasksRpcListener           Passed
SERVERNAME         TcpListener                Passed
SERVERNAME         DagMembersUp               Passed

Can anyone shed some light on what I can try please?

Thanks
