Pool Used Space Showing Wrong Size

[NAS0_DATA1]

Got a RAIDz1 pool with 4-1.6TB SSDs. I recently moved about 1TB from this pool to another pool. In the TrueNAS dashboard, the pool shows the wrong available size. But in Windows, the share shows the correct size. See attached pictures. What can I do so that the dashboard shows the correct available size?

They both show ~2.47 TiB free?

They both show ~2.47 TiB free?

On the dashboard it shows 1.6TB used yet on Windows the share shows only 16.3GB used.

Used isn't the same as free (available).

. Windows is basically only statfs output for the particular dataset underlying the share. Available / free is always correct, but used is more nuanced than windows can properly display. Space accounting in ZFS is complicated. If you want full breakdown of stats run command zfs list -o space.

My bad. You’re right. I mean to say used, and not free space. I’ll try that command. Thanks.

@anodos Ran the command and this is what it showed:
Available 2.47TB
Used 1.62TB
UsedSnap 1.61TB

Looks like snapshots is using up all that space.
