I've been following some of this thread and everyone is asking for options to 
increase space (at
least the posts I've payed attention to).

I've sort of done the exact opposite.   After I had my order laid down, I used 
ISPF 3.4 
to free space on the largest data sets in order to get my IBM sysres set down 
to 
2 3390-9 volumes.  This includes IBM program products ordered with ServerPac.
One of the 2 volumes is (was) zFS only, and I had to put SYS1.SFONDLIB on that 
volume.
I have about 550 CYL free on my primary sysres volume and 700 free on the
zFS (+ SYS1.SFONDLIB) volume.

Adding an extra volume to my sysres set would have really meant 20+ extra
3390-9 volumes due to the number of sysres sets / sysplexes in my environment.  
 So 
I really wanted to avoid it one more OS upgrade and plan for it in 2 years for 
z/OS 2.2
because we are in the process of adding DASD now and planning for the next 
year or two of projected growth.   Even though we have a lot of the old
FONT libs / products, we didn't have SYS1.SFONDLIB, so at least that was new
and I could catalog it to &SYSR2 to start.  :-)

Adding an extra volume and moving things also means having to play games
on my current environment with some temporary symbol to catalog data sets
to I want to move,  having them live in 2 places, then changing the symbol
to the new volume to facilitate rolling IPLs across a large number of systems
in a given sysplex (at least some sysplexes), then when completed recataloging
the data sets to &SYSR3 (for example) and deleting the original one from
&SYSR1.   I've been through this sort of thing before when 3390-3's started
being inadequate and then had to do the opposite to get back down to a
single 3390-9 (for all but zFS).   

Yes, I will run into some space issues during SMP/E mass maintenance (we do
quarterly RSU), but SMP/E will compress and debatch updates when it can.  Also, 
not
every component gets touched at ones even when doing mass maintenance - or at
least not touched with a large amount of fixes.   For example, the huge font 
libs 
aren't going to have updates on any regular basis if at all.   

OTOH, I think I saw someone mention SERBLINK and SISFLOAD.  I seem to
always have to increase those, but they are very small in comparison some
of the big libraries.
