Understanding DFSR debug logging (Part 4: A Very Small File Added to Replicated Folder on Windows Server 2008)

Article
03/25/2009

In this scenario we will see a small file copied into the replicated folder and how it is replicated between two servers. This is useful to understand in order to troubleshoot issues where problems within the USN journal, the DFSR JET database, the staging folder structure, and the network (including RPC) are preventing replication from working correctly. If you haven't read Part 3, this isn't going to make as much sense, so make sure you review that.

(tinyfiledownstream - Dfsr00005 - 2008.log and tinyfiledownstream - Dfsr00005 - 2008.log)

These are two Windows Server 2008 servers called 2008MEM01 and 2008MEM02 in the fabrikam.com domain. The logs are from 2008MEM01 where the file is created (upstream) and from 2008MEM02 where it is replicated (downstream). Both servers are participating in the TESTRG replication group for the TESTRF replicated folder. The file is called "tinyfile.txt". It is smaller than 64KB so it will not need to be staged for RDC usage nor will it be XPRESS compressed.
