I have a zpool called data, and I have some inconsistencies with sizes.

$ zpool iostat
               capacity     operations    bandwidth
pool        alloc   free   read  write   read  write
----------  -----  -----  -----  -----  -----  -----
data        3.32T   761G    516     50  56.1M  1.13M

$ zfs list -t all
NAME                            USED  AVAIL  REFER  MOUNTPOINT
data                           2.21T   463G  9.06G  /data

Can anyone throw any light on this?
Is not free the same as AVAIL?

I do not have any zfs snapshots, but some filesystems are compressed.
