My server's disk space is full but I can't see where it comes from

today my server crashed and I realized that it was because there was no more space available on my disk

When I enter df -H I've got this :

udev            997M     0  997M   0% /dev
tmpfs           203M  1.1M  202M   1% /run
/dev/sda1        21G   21G   76M 100% /

So the files that takes a lot of space is in /

but when I type ls -a -Ssl --block-size=k / I've got this :

16K drwx------   2 root root 16K Sep 30 21:59 lost+found

 0K dr-xr-xr-x  13 root root  0K Feb 17 15:00 sys

So It's like empty... I really don't understand from where these 21go comes from

Any ideas ?

Thank you and I wish you a great day :)

Does this answer your question? [disk is full, but cannot find big files or folders](https://askubuntu.com/questions/413358/disk-is-full-but-cannot-find-big-files-or-folders)

You do not say what version of Ubuntu this is If sda1 is when the OS is installed it is less then the min recommended for Ubuntu 20.04

ls doesn't calculate size of folder contents

you can use du to calculate folder content sizes

e.g sudo du / -d 1 -h -c

starting at root "/" one directory level "-d 1" human readable "-h" give total "-c"

can then repeat for large folders

you may get some "cannot access" for various reasons

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.
