    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!

    Blargh. You'd think imgur would be acceptable. Thank you for letting me know.

    And actually… here's from tonight:

    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:

    Code:
    df -i
    If the inode usage is high, here's a command to verify where the inode usage is coming from:

    Code:
    find / -xdev -printf '%h\n' | sort | uniq -c | sort -k 1 -n
    Thank you.
