ZFS filesystem not showing total size?

Hello.

I've got the following hardware setup:

ad10: 76319MB <WDC WD800AAJS-00WAA0 58.01D58> at ata5-master SATA300
ad11: 953869MB <WDC WD1001FALS-00J7B1 05.00K05> at ata5-slave SATA300
ad12: 953869MB <WDC WD10EADS-00L5B1 01.01A01> at ata6-master SATA300
ad14: 476940MB <WDC WD5001AALS-00L3B2 01.03B01> at ata7-master SATA300
ad16: 476940MB <WDC WD5001AALS-00L3B2 01.03B01> at ata8-master SATA300

ad12 is used as a single-disk pool. ad10 is formatted UFS2 for the OS.

I'm attempting to create a RAIDZ pool (with parity) over ad11, ad14
and ad16.

I've performed the following steps:

# zpool create storage raidz ad11 ad14 ad16
# zpool list
NAME                    SIZE    USED   AVAIL    CAP  HEALTH     ALTROOT
backup                  928G    166K    928G     0%  ONLINE     -
storage                1.36T    292K   1.36T     0%  ONLINE     -

# zfs create storage/home
# zfs create storage/home/xw
# zfs set compression=gzip storage/home
# zfs set compression=gzip storage/home/xw

# zfs list
NAME              USED  AVAIL  REFER  MOUNTPOINT
storage           188K   913G  25.3K  /storage
storage/home     49.3K   913G  25.3K  /storage/home
storage/home/xw  24.0K   913G  24.0K  /storage/home/xw

I seem to have less storage than I'd expect. Is there something wrong
with this setup?
