Here is the result of a "df" on my system - this is of course a snapshot of 
what it does.  Already come and gone is a LV for a subversion repository and 
an LV for /var/www (I used to hold a debian mirror there created with 
apt-move - but now I just use apt-proxy so I released the space). Of special 
interest is the last entry which is a special LV I created in order to build 
kde debs.  You need an "unstable" system and this machine is running sarge, 
so this partition contains a chrooted unstable system.  I had no idea how 
much space would be needed, and initially allocated 2Gb - I subsequently 
increased it twice (to 3Gb and then to 4Gb) as I started to run out of space.

You will also notice this flexibility encourages small little partitions for 
specific purposes.  All the separate partitions in /bak are various other 
machines backups and since I don't know how much space each might need at 
anyone time its easier to create separate LVs

The last thing to say is that the Volume Group vg covers three disks (a second 
partition on /dev/hda, most of /dev/hdb - a small swap partiion is also 
allocated - and all of /dev/hdc - although I followed recommendations and 
made a single partition /dev/hdc1).  The /bak/roo LV is all allocated on 
/dev/hdb2 and the other non /bak LVs (apart from the last - which I don't 
backup and therefore did not bother to worry about where it is) NOT on 
/dev/hdb, so I can do genuinely do a disk to disk backup of my system (this 
was why I agonised over whether I needed one or two volume groups in the 
original setup - see earlier post).
