About the free space

zpool list shows you the size of all your disks lets say (5 * 250 GB=~1.2 TB) including parity space.

zfs list shows you the space available to filesystems/volumes, after all the parity is accounted for. With 2 parity disks, you get 3 * 250 GB = ~750 GB. Add in ZFS overhead for redundant metadata and other info, and you get what you see.


regards,
Johan Hendriks
