Hello All,

Core 13.0-U5, 32GB Memory, Xeon E3-1200 4-core, 128K SSD boot, 12 8TB spinners pool.

Used Space is currently 94%. It was 58% prior.
I discovered late last Tuesday that my "video" dataset (/mnt/pool/eds/video) was empty. Everything had been erased.
Snapshot retention is for seven days .
Monday's snapshot REFERENCED 23.9TB. Tuesday's snapshot REFERENCED 0.0TB
I deleted Tuesday's snapshot.
I hit the ROLLBACK button on Monday's snapshot (several times) and nothing happened.
The "video" dataset forever remained empty.
After much failed research into how the ROLLBACK button is supposed to respond, I moved on to the CLONE TO NEW DATASET button.
CLONE TO NEW DATASET worked. I cloned /mnt/pool/eds/video to /mnt/pool/eds/video-clone.
Used Space went from 58% to 94%.
In an SSH shell with su -, I moved (mv instruction) all of the data from the "video-clone" dataset to the "video" dataset.
The "video-clone" dataset was then empty and the "video" dataset was returned to normal.
Used Space remained at 94%.
In Storage-Pools I deleted the /mnt/pool/eds/video-clone dataset.
Used Space remained at 94%.
I have now waited 8 days. All snapshots prior to doing the cloning have been automatically deleted.
Used Space remains at 94%.
The video-clone dataset (/mnt/pool/eds/video-clone) contents were moved and then the empty dataset was deleted last Thursday, 8 days ago.
There is no "pool/eds/video-clone" snapshot on the system.
Used Space remains at 94%. It should now be back to 58%.
Somehow, after deletion of the "video-clone" dataset, the 24TBs of space used by the "video-clone" dataset during the recovery operation, has never been released.
ZFS shows below that pool/eds has 62.6TB USED but, if you add up the children of pool/eds from 'backup" to "video"you get slightly less than 40.1TB USED.

I pray someone knows what this issue is about and is kind enough to reply with a solution.
Thank you in advance.

Here is the "zfs list -o space -r pool" output.
