ZFS is showing that the root pool is almost full but du(1) is unable to find where all of the space is being used.

$ zfs list
NAME                        USED  AVAIL  REFER  MOUNTPOINT
rpool                       268G  5.65G    97K  /rpool
rpool/ROOT                  227G  5.65G    21K  legacy
rpool/ROOT/s10s_u9wos_14a 227G 5.65G 227G /
rpool/dump                 2.00G  5.65G  2.00G  -
rpool/export               4.22G  5.65G  4.22G  /export
rpool/export/home          24.5K  5.65G  24.5K  /export/home
rpool/swap                 2.06G  5.69G  2.02G  -
rpool/testswap             33.0G  6.30G  32.3G  -

So the space is being taken up under the filesystem currently mounted as root, but running a du -shd /.[a-zA-Z]* /* does not find the space.
