To force a DFSR server to check with Active Directory (AD) for configuration/replication changes, use the DFSRDIAG command with the POLLAD parameter, as the following example shows: C:\Users\savadmin>dfsrdiag pollad When relying on DFS-R and its algorithms for mission-critical replication, this lack of visibility can be extremely frustrating for administrators tasked with keeping these critical services operational and users happy. To force an immediate retry, execute the command 'dfsrdiag /pollad'. The Backlog can reach up to a few lakhs files. It's not going down since once of the member's database is in auto-recovery followed a crash. ), Log Name: DFS Replication This process will keep repeating until the file gets moved to thereplicated folder and if the staging quota is kept low, in that case, theclean-up process runs more frequently to free up staging space.

Whenever we create a DFS namespace and DFS Replication group, the namespace and replicated group are stored into the active directory domain partition and if AD replication is failing, then the changes are not replicated to the remote domain controller, hence the DFS server in that site could not get those changes and could not initialize initial sync (one way sync). All Windows Server 2019-based domain controllers in the domain have the following event log errors: Log Name: DFS Replication Once we fix AD replication, the remote site DC updates its domain partition and during polling intervals, the DFSR remote member detects changes and start aninitial sync. There are no quotas in place on either server. DFSR Event ID 2213 is triggered after a dirty shutdown which provides commands to resume the specified replicated group manually.
