You can look to see what files have been created or altered in the last
day by using "find" (as root):

# find / -xdev -type f -ctime -1 -ls

For the last 2 days, change the -1 to -2

You can read "man find" to understand the options.

This will only show you files that still exist in the filesystem. If a large
file has been created and is still held open although deleted (unlinked),
it will not show up. But in that case, you can either search for it with
"lsof", or just reboot the system to reclaim the space.
