Continue with scenario 1 or 2 as noted above. On windows 2012 servers you must create this registry key if it does not exist and set the value to 0to enable DFSR auto recovery. To resolve this issue, the DFSR database needs to be rebuilt on the affected server. To resume the replication for this volume, use the WMI method ResumeReplication of the DfsrVolumeConfig class. Nothing to lose at this point. Level: Error We need to wait until DFSR finishes replicating all data from the primary member and triggers an event ID 4104 which means initial sync is completed and now both servers can replicate data authoritatively.

Improper staging area affects DFSR replication, After creating a DFSR replicated group, one-way sync is triggered by the primary member to secondary members. If the backlog counter is not going down, I don't think that your DFS infrastructure is actually auto-recovering from the crash. You see DFSR event ID 2213 on the DFSR server due to unexpected shutdown: The DFS Replication service stopped replication on volume D:.

The purged file now needs to be replicated from the source server again. Once you are able to retrieve DFS-R backlog counters, you will be able to verify how fast they are decreasing and estimate how long they will take to reach zero. CN=DFSR-GlobalSettings,CN=System,DC=,DC= msDFSR-Flags = 0. If the AD updates are done successfully to create the sysvol replication group but the registry changes the DFSR service aren't made because of missing user rights, you'll only see events 8010 that the migration is underway.

Resilio Connect delivers improved visibility, reliable replication, predictable (as well as faster) file propagation times, and much more as detailed in the table below. Since DFSR is a multi master replication technology, all members of the replicated folder once converged are considered as primary members and authoritative for any action taken on data and if data is deleted on one member, deletion gets replicated to all members and data loss occurs. Even after a few hours replication (initial sync) had not even started. Take ownership of this folder and grant the built-in administrators group full control on this folder.
