DAG replication issues Exchange 2010
Posted on 2012-09-18
I finished setting up a DAG in exchange 2010 last week with a mapi and replicaiton network. Aside from this, 2 of my active servers also have a SAN network. The 3rd and Passive server in the Dag has the storage locally in the server so no SAN network. I begined creating database copies last week and it worked for some and other just said resyncronizing or failed. I noticed that resyncronizing left a Copy Queue Length number next to the mailbox and it did not decrement at all so it didn't seem to be doing anything. After suspending and reseeding multiple times I decided to copy the database to the other server in DAG which left a re-syncronizing as well, but when this was done I copied that database to the 3rd server and suddenly all the copy queue length numbers begined decrementing leading to a healthy copy. In conclusing, the databases needs to be copied to all 3 servers in the Dag in order for it to work, i know this is not the way it should be but is the only work around I found up to now. I would like to find a solution to this.
