ZFS NAS configuration question

[Dan Naumov]

Is the idea behind leaving 1GB unused on each disk to work around the
problem of potentially being unable to replace a failed device in a
ZFS pool because a 1TB replacement you bought actually has a lower
sector count than your previous 1TB drive (since the replacement
device has to be either of exact same size or bigger than the old
device)?
