DFS replication problems after changing Harddisk

$

Hi there,

Here is my environment: 

We are using 2 Microsoft Server 2008 R2 and DFS to replicate data between two sites. My company does project development for wind farms so on both sites are important files. Our DFS storage is mounted from a QNAP via iSCSI to our virtualized DC which is not the optimal setup..

So yesterday I added a new virtual HD to the DC and copied all the data on it using the program Allwaysync. I made sure that all folders (each one has its on replication group) are synchronized between the to mounted HDs. After that I stopped the DFS-R service and switched the letter of the HDs. 

So here's my problem:

Since that point only a few replication groups work again. We have some smaller folders (up to 5GB) where the replication is working fine again. But our most important folder, the folder where all the project data is stored, doesn't replicate again (~250GB). I already run some Diagnoses reports. There is a warning which kind of says: Waiting for initial replication.

Now I'm a little scared, because my coworkers are modifying data on both sites in that folder and a initial replication is a one way replication from the primary host right? So what will happen with the data on secondary site that are modified today?

I already run a few dfsdiags backlog in cmd and there is a huge queue on the hosts (200000+ files).

Here is the result from yesterday evening 11:30 PM

Dateianzahl des Rückstandsprotokolls für Mitglied <srv-dc2>: 278424

and here from this morning 11:16 AM

Dateianzahl des Rückstandsprotokolls für Mitglied <srv-dc2>: 262153

 

I'm sorry that it is in German and I'm sorry for my bad English skills too. I hope you guys get the problem though.

 

What am I supposed to do now? I think I'm pretty much screwed when we have different data on both sites right? There is no 'master data' which i could simply copy again. And if I take a look at the overnight progress of replication it could take forever, if it will work at all again.

 

Please, I need help!
