We prefer to break things out into more individual partitions and make the
partition size the same across all AFS servers even if the total space is
different, mostly so that we can easily evacuate partition by partition
onto other servers.  I'm not sure it really makes any significant
difference except for concerns like that.

We try to keep volume size under 5GB because moving single large volumes
takes a long time and therefore there's more opportunity for something to
go wrong in the middle of a volume move, but AFS can handle volumes much
larger than that.
