I have a Ubuntu machine running 12.04 LTS on it. I had a very small "/" partition at the beginning, say of 16 GB. Now i added a 50 GB to it which i split from another partition and added to the "/". All the process has been done through gparted. Even after extending the partition, it still doesn't show that 50GB in as free space. Te 50 GB i added is shown as used, the free space still remains close to 1GB which was the same before extending the partition. Any Suggestions?
