The latter, an AFS partition contains volumes.

No, volumes are logical units and don't have a size. You can set
a maximum volume size (a quota, which is set on a per-volume
basis), and it's just a number -- it does not
make the volume bigger -- the volume will really occupy only
as much as the data you have in it.

Yes.

An AFS partition contains volumes. Volume's maximal size limit is
the size of the partition it is contained in, as volumes cannot
span accross multiple partitions.
