Reseeding of databasecopy keeps failing

Posted on 2014-03-29

Last Modified: 2014-05-13
Ok .. I've honestly run out of suggestions. Any help you guys could offer would be GREATLY appreciated. We have a remote office in China and an office in Dallas. We have a DAG with multiple databases for each of our offices. The database copies for China are housed in Dallas and the database instances are hosted in China. During a reboot of our China server, the databases fell back to Dallas. I have 4 databases. I was successfully able to activate copies 1,2, and 3, but on 4 I got the infamous "Failed and suspended". For days now, I've been trying to update (reseed) this database copy, from the copy in Dallas, but I incessantly get the following message:

Summary: 1 item(s). 0 succeeded, 1 failed.
Elapsed time: 03:37:14


A source-side operation failed. Error An error occurred while performing the seed operation. Error: An error occurred while communicating with server 'DallasExchangeServer.mydomain.com. Error: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.. [Database: SZXDB04, Server: ChinaExchangeServer.mydomain.com]

Exchange Management Shell command attempted:

Again, any help would be MOST appreciated.

Can you create a new database and get that to replicate? If so, just move the mailboxes across to the new database, which will seed the copy. Once complete, just switch the active databases across.

My instinct is that there is some kind of throttling going on, probably not at the Exchange level, but in the network hardware between the two sites somewhere.

I'm not understanding your suggestion. Create a new database in China (on the China server) and move the mailboxes into it, and copy it to DFW? Please advise. Thanks.

Doesn't really matter where you create the database, you want it active where the current database is active. So you could create it in China, add to the DAG and then fail over, or create it in the USA, add to the DAG, move the mailboxes, then failover.

What you do NOT want to do is have the database active in China and move the mailboxes, as then you are moving the data twice (once to China and then back again in the DAG replication).
