I have started using a machine that has both Debian and Windows 7 installed. However, after installing some programs I started getting a message that there is not enough space. I knew that the system had more than 1TB of hard disk space in total and did some research. It seems that the root partition is only 5GB.
Is there any way to allocate more disk space to the specific partition without reinstalling Linux?
Below you can find the results of a couple of commands that I executed:

As a sidenote, I would also appreciate any suggestions for good books that explain these subjects in depth (file systems, how the various operating systems understand the file systems etc).

? (Post the output ofmount
or the contents of/etc/fstab
if you don't know.) Also the output ofpvdisplay
(as root) would be interesting since you seem to be using LVM. – Mat Jan 01 '12 at 16:03/usr
