Thank you all very much. I appreciate the help.

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).

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:

Incorrect metadata area header checksum on /dev/sda1 at
offset 4096

The problem appears to be the "Free PE 0" from some
research that I did online. I want to know how I can fix
this issue so that I can then use lvextend to increase the
size of the root directory. What is a recommended value for
the size of this directory? I used the defaults suggested by
the partition manager during installation, but it is clearly
insufficient as seen above. Any help would be appreciated.
Thanks,
Sumant
