Exchange 2010 databases moving from 1 server to another but no logs are being written as to why

I've got a DAG with 2 mailbox servers as members and 10 databases evenly distributed over the 2 ( 5 and 5).  All of a sudden we'll log in and see all 10 on 1 server.  Looks through all the logs(win 2008) shows literally nothing indicating what may have occurred.

Anyone experienced anything like this or can point me to where i could be looking?

The only valid reason for this to happen if a failover occured. This would mean that there was either a disruption in service/communication or whatsoever that would've caused this. On the other hand; that would definitely show up in the logs.

Totally agree with Micheal, DB failover will not happen without a reason, one of the nodes was voted down and evicted momentary from the cluster. Go back in your logs there is surely something there.

Of course another option is that an admin manually moved them

yea i mean i'm a pretty experienced Exchange 03, 07 admin.  Now this is 2010 so a bit different but there is seriously nothing in the logs.  I mean i'm expecting all sorts of things that would be there but it can't honestly think of any reason it could move without anything getting written.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Gleek,

nor can we ;-)
I suggest that you monitor the situation closely and even enable some diagnostic logging on the Exchange Server to catch some details if that would happen again.

even if you move the DBs manually it will be written in the logs....
