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

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
