limit disk usage

So, in the past there was an issue with disk space being overrun by a log file. It used up everything on that server and was a pain to deal with. Before my time, so I don't know how it happened.

Anyways, on a rhel8 system, what's the best way to limit the amount of disk space used, over all. I know there is by user/group/project, but I have no way of knowing what user/group would be the cause. I could set it for each, but it would be easier to just have a hard limit.
