Hi, I have a Netgate 6100 pfSense appliance with ZFS. Everything is working fine and I know there is nothing wrong here but I am just trying to understand how the space is reported by each of the tools. diskinfo reports 477GB in bytes and the pfSense zpool list is 472GB. Where are the missing 5 GB? If I look gpart then freebsd-zfs is 475GB and freebsd-swap is 2 GB which adds up to 477GB on nvd0 but that's different than zpool list (472GB). Thanks!
