I am trying to understand the disk usage. I have 4 10tb pool drives (in Raid, which formats out as 26 TB), with truenas scale on an m.2 drive. I noticed that the my web interface is reporting 17.3 TB used. But when I enter the truenas shell, and do a full DU on the pool, it reports 14.4 TB used. I have looked at the backups, and the are just 0.5 TB of the 14.4 for example. Any clues where the other 3 TBs are. The only app I am running is jellyfin, with 9TB of media.

Snapshots could be one item. This may help you track down what you are seeing
Thank you for the help. I think this might be the answer, but it remains to be seen until the backups catch up. I started looking at this, but of a warning, saying that I am approaching 80% full. I deleted some 4TB give or take because of it. I had expected usage to keep up. If I understand things correctly, that does not happen until the previous backups are replaced/deleted.
Thanks again. Ed
