Description koobs 2012-12-29 11:40:00 UTC 
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

    /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.
