DFSR stops replication after a dirty shutdown in Windows 7 or Windows Server 2008 R2

Applies to: Windows 7 EnterpriseWindows 7 ProfessionalWindows 7 Ultimate More

Symptoms


Consider the following scenario:
  • On a domain server in a Windows 7 or Windows Server 2008 R2 environment, you have a Distributed File System Replication (DFSR) service folder.
  • Many replication activities appear in the folder.
  • The domain server performs a dirty (unexpected) shutdown.
  • NTFS journal wrap occurs after the dirty shutdown.

In this scenario, the DFSR replication of folders stops working after the DFSR garbage collection task is performed.

Cause


When there is a dirty shutdown, DFSR updates records by restamping and marking records as GC VersionVectorTombstone. Journal wrap also marks the record as not present. The garbage collection task goes into effect, and the database GUID is added as tombstoned GUID. DFSR then marks the database GUID as stale. When a new file is created, it is stamped with the stale database GUID. This causes the record to be filtered out from the version vector because it is a stale database. Therefore, replication does not occur.
