A question about the wording of that paragraph.  The second
sentence states:

"Because GPT partition schemes also store metadata at the end of
the disk, mirroring full GPT disks with gmirror(8) is not
recommended."


The word "full" is ambiguous.  Is it to mean, "full" as in 'full
of data', or "full" as in 'the entire disk'?


Thanks.
