Default / directory is 100% full

Hello,

I am new to Debian. I have Wheezy installed on my Thinkpad x230 laptop. My kernel is 3.2.0-4-amd64.
The problem I am getting is that my "/" directory is 100% full. Because of this, I am unable to update my kernel as I get an insufficient space error. However, my hard disk has almost 300 GiB free.

When I tried to run lvxtend to expand the / directory, I get an "Insufficient free space: 256 extents needed, but only 0 available" error. The filesystem is ext4 and I am using an encrypted LVM.
Some more detail can be found in these outputs:

The problem:

root@debian:/# lvextend -L +1G /dev/mapper/debian-root
* Incorrect metadata area header checksum on /dev/sda1 at offset 4096
* Extending logical volume root to 1.32 GiB
* Insufficient free space: 256 extents needed, but only 0 available

Some tests:

Default / directory is 100% full

You made a mistake when you try to extend your LV, first of all you
have to check what PV you have (pvs will show you that), then you'll
have to check if there is some free space available on your vg (vgs
will tell you that)



Then you will be able to add space (regarding how much you have
available from vgs).
