Maybe any live CD/USB with gparted can help? If you do not have any space on sda1 I think you should either remove something or buy another disk...

Sorry if this is a fool suggestion.

As with other logical volumes you cannot the extend / volume easily.

df output shows only 16 GB is used, check the list of all the open files via lsof command so that you can get an idea which is causing high disk space consumption by looking at the output.

Something does not make any sense here.

First of all the OP states that he is using LVM but that is not what df output shows.
Second, the df output for / is suspicious.

In case you created a new 10 GB logical volume (besides your non-LVM root disk), you cannot attach a logical volume to a disk that is not managed by LVM.

Please post the output of:

fdisk -l
