Hi,

While I have not tried this myself, I know that parted can be used to resize partitions without data 
loss.  I would backup the data on the server prior to trying resizing, then try to resize. You may 
use some of the ideas from this howto (even though you are trying to go the opposite way):

http://www.hermann-uwe.de/blog/resizing-ext3-partitions-with-parted

The ideal situation is to have the following:

/dev/hda1 for /boot
/dev/hda2 for /
/dev/hda3 fo /var
extended partition
/dev/hda5 swap
/dev/hda6 for /deb/drbd0
/dev/hda7 drbd metadata

However your system configuration may not allow for that or you may not want to have a separate var, 
etc...

HTH,

Diego
