Running Out of Space on Root Partition

So for the past couple of days I have received emails from cPanel warning that `/` and `/var/tmp` are running out of space. Here's a screenshot of the email alert, which shows the same numbers for the two locations:- Removed - - note I have redacted the ip and servername, of course. But here's a screenshot of the `df` command: - Removed - Note that I am using CloudLinux+CageFS. Also, while I'm comfortable in the commandline, I'm not a Linux expert. I'm still learning. Not totally lost, but not an expert. Am I truly running out of space in a.... partition/mount/whatever? How can I tell for sure?

  Hello, It looks like the links were removed due to the use of a third-party image hosting URL. Can you attach the image directly to this thread, or post the output in CODE tags? Thanks!

  And actually" here's from tonight: 51503 51507 I don't know if there's an error, or a lack of Linux knowledge - it seems the weirdest thing to me is that I don't thing `/` is only 47GB in size. Also, for the message from WHM - I got four emails - Two at 3:15am with DISKWARN for `/` and `/var/tmp`, and two for the same with DISKCRITICAL. Each pair showed similar but different "Used" - the other pair had ~41GB used; all four show same "Total". If it helps, I host with SoYouStart, one of the OVH companies, although unlike Kimsufi, at least I could install CloudLinux+CageFS. Thank you again :)

  Didn't mean to sound that complain-y. It's a good point and good policy. :)

  Hello, The first step is to determine what's taking up the disk space on the system. We offer a document on how to do this at: How to Manage your Hard Drive Space - cPanel Knowledge Base - cPanel Documentation Also, ensure to review your available disk inodes as well. EX: df -i
  If the inode usage is high, here's a command to verify where the inode usage is coming from: find / -xdev -printf '%h\n' | sort | uniq -c | sort -k 1 -n
  Thank you.
