Free space in ZFS

I made a three disk zraid ZFS pool yesterday from three new 1 TB
disks, which I'm using for backup. Then I did a backup and made a zfs
volume. The free space numbers don't make sense. This is on 8.3, ZFS
version 15.
# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
backup2 2.72T 310G 2.42T 11% ONLINE -
Given that it's zraid, the total available space should be a little
under 2TB since the third disk is for parity. But zpool gives me a
total of 2.72T, as though the third disk was for data.
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
backup2 206G 1.58T 31.3K /backup2
backup2/20120615 206G 1.58T 206G /backup2/20120615
Well, that makes more sense, total is 1.78Tb.
# df -g
Filesystem 1G-blocks Used Avail Capacity Mounted on
backup2 1618 0 1618 0% /backup2
backup2/20120615 1825 206 1618 11% /backup2/20120615
Now the total is 1.82Tb. Huh? The backup filesystems are compressed,
but surely they're showing me the actual size, not the uncompressed
size. Or are they?
R's,
John
