Missing free space from new raidz2 zpool

Hi,
I got redirected here from serverfault. Original post:
https://serverfault.com/questions/724542/missing-free-space-in-new-zfs-raidz2-zpool
So let's start from the beginning.
I'm running Nas4Free 10.2.0.2 - Prester (revision 1814) which is based on
FreeBSD 10.2-RELEASE-p2 #0 r287260M: Fri Aug 28 18:38:18 CEST 2015
System has 24 GB ECC memory.
I bought 6 new 8 TB drives and created new raidz2 pool with these drives.
Drives were only seen as 2.x TB. So I deleted the pool and moved the drives
to plain SATA ports from SAS controller & SAS expander. Now drives are seen
correctly by MB.
My question is why zfs list and df is only showing 14.5T free? Shouldn't it
be more close to 30T? Or is that old zfs metadata somehow lurking around
and zfs is reading that? Bug?
Thanks for help.
