CentOS getting full - where it's hogging stuff?

My VPS' CentOS getting full, I am not at 90%, and I don't have anything big there.

I wonder where it's hogging stuff and what can I clean safely? Who can help me with a hint?

    Well, you know, the usual places:
    In the cellar, in the Garage, under the sink, in the lower drawers of cupboards and ... above all: kids rooms. Look at the kids rooms first.

    That assumes you are even talking about „full“ as in „storage“ and not as in „gets drunk and slows down“ or „needs brainwash aka swap“.

    Apart from this generic advice it would obviously help to understand if there’s specific stuff like backup routines running / buffering somewhere, to check if some logging runs amok in /bar/logs ... or just to generally follow the path of „who had the fattest butt“ in ‚du -h —max-depth=1‘
    Or something like that.

    Is your VPS openvz ?

  • Thanks, I am a bit unclear what it means though.

    I use Webmin. VPS is on KVM if that matter and I just have 3 domains on it, all three use email, two of those heavily.

    du / --max-depth 1 -h

  • Ok, lets try...

     du / --max-depth 1 -h
    1.7G    /var
    4.0K    /selinux
    4.0K    /media
    487M    /lib
    43M     /opt
    5.7M    /bin
    4.0K    /mnt
    4.0K    /srv
    16K     /lost+found
    7.9G    /home
    160K    /dev
    0       /sys
    323M    /etc
    114M    /boot
    4.4G    /backup
    1.1G    /usr
    du: cannot access `/proc/15284/task/15284/fd/4': No such file or directory
    du: cannot access `/proc/15284/task/15284/fdinfo/4': No such file or directory
    du: cannot access `/proc/15284/fd/4': No such file or directory
    du: cannot access `/proc/15284/fdinfo/4': No such file or directory
    0       /proc
    29M     /tmp
    18M     /root
    15M     /sbin
    16G     /
    

    Found one black hole in:

    5.6G /home/domain1/app

    It's used by bolt.cm CMS as cache - which I didn't clear in a few years. I am down from 6.4G to 0.8G in that folder.

    I think I am good for now.

    rm -rf /home. Clearly it is taking up all the space.

    I am careful with any rm etc., du is good to display stuff. For the cash cleaning I used the delete cash function in bolt.cm . Strangely, I have two bolt CMS on my VPS but only one is hogging cache data.

    All backup files I deleted. They were from 2016. That is one thing really bad about RamNode, you never think about failure.

    I think I will look into external backups onto my NAS. Backup on the same VPS is maybe not that useful anyway.

    Yeah, rm can be accidentally really bad. Never know who reads these comments. That's why I don't like rm jokes without warnings, because it can be really harmful.

    So they say, backups on the same vps or even on the same node are mostly useless. :smiley:
    Hopefully you'll find a solution.

    But what does even rm mean? remember? Executing commands from random strangers on the internet, instead of reading the manual page first, is a sign of safety happening, practically.

    But aren't things you read on the internet mostly true?

    Not only true, most things on the internet are a fact.

    Well, if you execute random commands or scripts from the net without checking what they are doing first, you deserve no better in case they are harmful imho.

    It is sad that people who on purpose try to make harm do not take responsibility for their actions. If someone spreads fake and harmful instructions, it's not victims fault when they harm themselfes. The responsibility lies with the one who deliberately misleads. The civilized world has laws to protect people who are weaker. It's just cruel to make fun of them by making them do stupid things. Every decent forum should ban everyone who try to cause harm to anyone by misleading or somehow else. IMHO

    The purpose was just fun, of course it is your own fault if you blindly follow instructions.
    You would point a loaded gun to your head and pull the trigger without thinking, if someone told you so? And then blame others for your own stupid actions?
    No one makes doing anyone anything.
    No one is trying to cause harm.
    If you don't have a clue about the rm command you should probably stay away from *nix/linux machines anyway.
    Calm down and find something else to rant about.

  • Never thought anybody can think it's ok to make people kill themselves. I'm speechless.

  • @eol I'm still curious.

    Just think, if possible; should 80% of the population do this, then the gene pool would improve drastically, many crises would be avoided, other creatures would benefit and the planet may survive a few more millennia. Oh, and there'd be fewer Summer Hosts

    Check for inodes usage. Your disk space can be 60% full but applications will complain about lack of space. df -i and see if inodes are all used up (especially on ext4 with Docker).

    You could always ask for a support from your provider. They will provide you the right commands just like this one.
