I am fairly certain that there is some (big) problem with my disk space on my RHEL 7 computer.My root filesystem currently says it is 41G/49G used (with df -h). I already know that there is 3-5% of the disk space used for the system. However when I run du -csh /, I get 9.5G total, and when I unmount my /home directory (holding the most disk space), I get 5.6G total. There is absolutely no way that there is a 20-30G disparity between df and du.I have checked that there are no large files that are waiting to be deleted (lsof | grep deleted), and killed any and all processes that showed up. Despite this, I still end up with the same 41G/49G used.I have looked for any files in the entire root directory greater than 1G (find / -size +1G) and the only one that shows up is /proc/kcore, which apparently has a size of 128TB, so I'm pretty much just ignoring that.I have rebooted multiple times. I have put the forcefsck file into the root directory before reboot. There is absolutely nothing that seems to work.I got this problem when I was pulling a couple of large docker containers and didn't realize that my disk space was hitting maximum before it crashed. I rebooted, removed the docker rpm, removed the /var/lib/docker directory, removed the /etc/docker directory, and even removed my local private registry. As far as I know, there should be nothing left from the crash, especially after all these steps that I've run. However, it would make sense if they were somehow still behind despite these efforts because they both totaled about 26-27G in space.Is there anywhere else I can go from here to get back this seemingly lost disk space, or is it pretty much a lost cause? Thanks!
Free Disk Space not Correct?
