Large Used/Free Space Discrepancy
Hi, I'm trying to work out why our backup NAS system is reporting such a huge discrepancy between our consumed space and our free space. As per the screenshot below, the consumed space adds up to...
I've discontinued the use of these NAS boxes and moved to custom fileservers. We were using about 20.5TB. No doubt recreating the volumes would have helped recover the missing 1-2TB.
There's definitely no space freed up, but based on the backup I'm doing to the impending replacement system, even a fresh volume would probably just make it mostly report higher usage on each share.
That said, it will probably be worth trying that route anyway once I'm satisfied I have safe copies of the data. It will take around a week over a gigabit connection though, so this thread will be idle until then.

Space is freed up in the background, so you might look again (now that the system has been up for a while).
Another approach is that you can make a backup of the shares, and then delete/recreate/restore them one at a time. Or of course start fresh - delete the volume, create a new one, and restore the data.
