We have two files servers, FS1 and FS2, running on two different boxes in the same server room (protection against a server failure). Both are running Server 2012R2, running DFS with deduplication and replication.
We had a power failure and FS1 didn't acknowledge the UPS power down command and subsequently shut down hard. FS1 came back up dirty, needing to run the wmic command. After several hours of running, it seemed to just stop. This got alot of files back in sync, but still most of it is not. At this point we've changed DFS so that clients don't connect to FS1, at least this way files people create can be found again when they logon. My question is what can we do to restore synchronization? I see some things about robocopy but I wasn't very comfortable implementing it in our situation. While we have backups, a full restore because something went wrong would be best avoided, as due to the amount of data it would take a very long time to restore. I wouldn't mind even decommissioning FS1 as it's outlived it's usefulness (an old HP G5 upgraded to server 2012R2). What can I do to sync it though seeing as I know files have been modified and are in use on FS2. I want the files that were "abandoned" on FS1 back over on FS2.
