IMO on a server setup service specific data should be stored in a 
separate filesystem mounted on /srv, not in the / filesystem.

You can resize a logical volume online, but AFAIK you cannot resize a 
swap area online (while in use) ; you must disable it (i.e. reload its 
contents back into memory), re-create it with the new size and re-enable 
it. Not an option when the swap space is filling up and you quickly need 
to add some more. Fortunately LVM allows to easily create a new volume 
for extra swap.

And please, folks, don't :
- give meaningless names such as vg1, vg2, lv1, lv2... to your VGs and LVs ;
- add affixes such as "vg" or "lv" to your VG and LV names. This 
produces ugly device names and is really not needed. You already know 
they are VG or LV names.
