Ubuntu using 100% disk space but I can only find 9.5GB
I have an Ubuntu x64 9.10 server without a GUI and it's completely out of disk space. I've used all of the conventional methods for locating the problems files/directories and I can only find 9.5GB out of 250GB being used. Running a du -hca / plus some other commands I've found all find the same tiny amount of data usage.
The server is running MySQL / Apache with a heavy MySQL database but the database and logs only uses about 6.5GB of space.
