I have a ZFS Pool that shows in the GUI as having a total of 10.9 TB and windows only shows only a total of 7 TB.

The pool originally consisted of 3 - 2 TB drives and I did replace each one with a 4 TB drive using the expand ZFS directions.

Each one did resilver completely.

Is there that much overhead?

Any ideas?

Thanks

Looking further I noticed that in Diagnostics|Information|Space Used is shows 7 TB Total space.

assuming that you have a raidz1 setup that sounds about right.

that 10.9 tb includes the parity information the 7tb does not.

Yes I do have a raidz1.

Thanks for the clarification.

The GUI can be miss leading.
