Interviewer: Lets say there is a partition of 100GB. When i tried to create a file using touch command, under any directory, it was unable to create the file- '100% full disk space'. I calculated the size of each and every directory on that partition mannually by adding each file size & in came out to be total size 50GB. Then where is the remaining 50GB ? why it is showing disk space 100% full in 'df -h' command?
