system thinks it is maxed out on storage

I seem to have run into a strange issue that is causing many problems.
for context, I am sshing into a 22.04.01 server VM constructed on a truNAS network with 18.1G storage and 12G RAM. I am using this to run game servers for me and my friends to play on using docker compose. I ssh into my VM I'm told

Usage of /:                       97.4% of 18.10GB

and this is causing many programs to crash due to insufficient space to write to. The strange part of this is that when I run sudo du -h -c I'm told that I have 7.0G total
df tells me

801M is being used in /var/log/journal/944d63898a804cb69cf9b59f62532cb0 but I cant read the files in there.
output for sudo du -hcxs / is just

18G     /
18G     total

Please do ask for more information as needed as im not sure what to provide!

What does `df` tell you, also can you install and run `tune2fs -l /dev/whatever` to see reserved blocks

Do any of the programs that are writing to disk use sparse files? That could account for the discrepancy. Note that about 2GB of your storage is going to be dedicated to the `root` account to ensure logs can be written when the main user space has run out of storage.

@matigo what are sparse files? I'm pretty new to all of this stuff and just started high school this year so I have not been able to focus on it as much

@thomasrutter I'm not seeing ```tune2fs``` in apt, how do I install that?

That `100%` for `ubuntu--vg-ubuntu--lv` is certainly an issue. Check your log directory (`/var/log`) for large files as that's often the first place to check. Be sure to *read* some of the logs before deleting them so that you can find out what problem is being reported (aside from a lack of space) as log files should not consume more than a few hundred MB in normal circumstances.

What is the output of `sudo du -hcxs /`? Also, if you can, try to install `ncdu` and run `ncdu -x /` to show where all your space is being used.

@Terrance i can not install that due to the root of the issue

@Thewolfhearted tune2fs is in e2fsprogs. Looks like your root is full though. I don't know why du only showed 7GB

@Thewolfhearted You may have only ran the `du` command originally within another directory which will return the amount of space used in just that directory and none other, unless specified after the switches which you didn't show us if you did. `df` on the other hand will return available and used for all mounts. I had you run that `du` command in my other comment to show that the entire mount is full. Have you removed downloaded files? Maybe check the `/var/logs` directory for big log files as you may be experiencing an issue with your OS?

Also, 18GB can fill up really fast in an environment like that. I have VMs that are clean installs that are already at 13GB. I also have a Xubuntu 22.04 VM I just spun up at 18GB. Consider a larger mount.

Turns out I ran sudo du -h -c in the wrong directory and I am actually out of storage, simple mistake on my part!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
