Incorrect RAIDz2 "Free" space reading in the dashboard

[TimmyDingler]

What's shown in the dashboard for "Free" space (3.99TB):


How much space is actually "Free" (1.70T):


How can i get the dashboard to show this statistic accurately?

The Webgui (at that location) shows a Pool while "zfs list" shows information regarding a Dataset. There must be some websites explaining the difference...

There is no one-sentence explanation for this. To enhance confusion you may compare the output of zpool get all tub and zfs get all tub...

I understand now; there was a misunderstanding of ZFS originally.
I appreciate the explanation, as I thought ChatGPT did not explain this "problem" as well as you did.
