DFSR Replication Group (FileHash Tables)

I have an DFS environment that has three servers.  ServerA is at head office, ServerB and ServerC are at two seperate remote sites. The Namespace that has been configured has 7 target folders, in which in has their own replication group configured for replication in a mesh topology.

ServerA and ServerB are in synch with each other, but discovered that ServerC is not.  further investigation has determined that the robocopy command that was used wasn't correct so it's having to copy all the data.   Most of the 5 out of the 7 folder targets are fully synched up, but the last two have large amounts of data.  We've preseeded the data again from ServerA and have verified that the filehash on the USB drive and ServerA are good.

If I delete the replication groups, should that delete the filehash table that is created in the filehash database?  So, that the intial synch will be a clean start?

DFS is running in domain-based 2008 mode, with all servers running Windows 2008 R2.

Thanks

Hi,

No if you delete the replication groups, it will not delete the file hash table on downstream server if the file is similar.

Refer the below mentioned article

 you can compare the fileshash on different server after initial sync.

So it's currently in Initial replication phase right now.  If I do the following:

1) disable DFSR replication
2) Remove DfsrPrivate
2) Remove Member from Replication Group
3) Copy the new files over top of the existing ones (keeping the proper hash codes)
4)Add Member to the Replication Group
5) enable DFSR replication.

Will DFSR redo the filehashes from the new server?
