Primary DFS-R member (Win 2012) deletes files on initial sync

Hi there,

Yesterday we set up a new DFS-R server (Windows 2012 R2, windows updated) and configured the various replication groups we needed. After a bit of time we saw that the DFS-R wasn't replicating on some RG, because of the event 4004, (error 9098, a tombstone content....)

We followed this post 2K8 DFSR Replication not working set the IsPrimary on all the RGs. Everything went ok and the smaller RG began to show as fully replicated in a few minutes (event 4104)

At 0:37:23 the biggest one (Clients) had the 4104 posted on the new server.

This morning the users had lost most of their files and after looking for them we found that on the RG Clients, DFS-R was detecting conflicts and moved the files to ConflictsAndDeleted, as the quota for ConflictsAndDeleted was smaller than the sum of the files moved, we lost some files and had to restore from backup

On the primary and production server we found many log entries that show that although it was the primary (no typo setting primary), it though that was a good idea to move the files because the secondary had a better version of the file. As the file isn't on the secondary server we think that was only referenced on the DFS-R database

I attach what we see about one of the file moved:

As you could see, the fence is "Initial Primary" (MSDN - Fence) so although the remote has a newer version, should be overwriting it as it is a primary one, isn't it?

We currently solved the crisis, but we will need to enable again DFS-R and we can't have the same problem again

Thanks in advance

Sergi
