We've turned on data deduplication on Server 2012 about two weeks ago. Since then, users are coming across corrupt files that cannot be accessed. At this time I was able to look in Event Viewer at exactly which files were corrupted. About 4 days ago, I found some instructions on "Unoptimization" using powershell command: start-dedupjob -Volume <VolumeLetter> -Type Unoptimization. I waited until after-hours and ran the unoptimization process overnight. When the unoptimization finished, I rebooted the server. I could see the volume size grow but Server Manager still lists the Deduplication Rate at 21% and lists the Deduplication Savings. Today, Monday, users are still reporting corrupt files again.
What do I need to do to get the volume unoptimized? Do I need to completely uninstall the role? Deduplication is disabled. If I attempt to run the optimization command again, it fails immediately. I cannot find any new info in Event Viewer, nothing relating to specifics of the unoptimization or why it fails if I attempt to run it now.
Any help would be appreciated.
Thanks.
