I have been asked this question in two consecutive interviews, but after some research and checking with various systems administrators I haven't received a good answer. I am wondering if somebody can help me out here.
A server is out of disk space. You notice a very large log file and determine it is safe to remove. You delete the file but the disk still shows that it is full. What would cause this and how would you remedy it? And how would you find which process is writing this huge log file?
