FreeBSD freebsd-91-amd64 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243872: Wed Dec 5 16:49:35 EST 2012 root@freebsd-9-amd64:/usr/obj/usr/src/sys/GENERIC amd64
>Description:
zfs 'list' and 'iostat' commands only display disk/file sizes when they are configured as top level vdevs:
[root@freebsd-91-amd64:/usr/home/user/zfstest] zpool list -v
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT

/home/user/zfstest/zfs14 - - - -
Similarly, per-vdev information for 'alloc and 'free' values are not displayed in zfs iostat output:
Expected output:
NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT
test-raidz 178M 177K 178M 0% 1.00x ONLINE -
raidz1 178M 177K 178M -
/home/user/zfstest/zfs1 59.5M value value -
/home/user/zfstest/zfs2 59.5M value value -
/home/user/zfstest/zfs3 59.5M value value -
If it is non-trivial to determine or calculate ALLOC and FREE values, SIZE only would suffice.
