I was looking through the event logs and discovered that Data Deduplication had been disable and it had found 2 corruptions. The file that it mentioned is not important and I can restore that file from backup.
How do I clear the deduplication error so I can re-enable Data Deduplication?
I have already ran a deep scrub full and that did not fix the corruption. I have also run check disk and no errors were found. This is an 8 TB share that has 5 TB of data deduplicated. I do not have the extra storage capacity laying around to copy all of
the data off of the volume to reformat it, I would have to purchase additional hardware.
