No! 'zpool list' will show what is used on disk. zfs list is totally transparent to zpool layout. Have a look at 'zpool get all' for the ashift setting. Example for raidz1 (4x 960GB SSDs): root@foobar:~# zpool list NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT zpool 3.41T 102G 3.31T - 8% 2% 1.00x ONLINE - root@foobar:~# zfs list NAME USED AVAIL REFER MOUNTPOINT zpool 237G 2.17T 140K /zpool zpool ALLOC is smaller than zfs USED in this example. Why? Try to unserstand the difference between 'referenced' and 'used'. My volumes aren't sparse but discard is used.
