Re: zfs: df and zpool list report different size

According to Alexandre Biancalana:
# zpool create backup raidz ad9 ad11

Note, raidz with two disks is almost the same as a mirror so the real,
usable space is half. In raidz, if you have N disks, the total usable
capacity is N-1.

# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/ad8s1a 72G 2.2G 64G 3% /
devfs 1.0K 1.0K 0B 100% /dev
backup 293G 0B 293G 0% /backup

# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
backup 596G 222K 596G 0% ONLINE -

My doubt is why zpool list and df -h report different size ? Which of then
is correct and should I trust ?

Both :)
