I have an entry level doplet (20GB) and have some files and an unfinished project. Today I tried to install VCN But the installation stopped halfway because there was not enough space. here is my usage,

root@aaa:/# du -s * | sort -nr | head
du: cannot access ‘proc/19923/task/19923/fd/4’: No such file or directory
du: cannot access ‘proc/19923/task/19923/fdinfo/4’: No such file or directory
du: cannot access ‘proc/19923/fd/4’: No such file or directory
du: cannot access ‘proc/19923/fdinfo/4’: No such file or directory
5496816 var
1330076 usr
1048580 swapfile
394848 lib
63980 boot
41200 root
11312 sbin
9328 bin
6688 etc
740 1.sql

And the df is,
root@aaa:/# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 20G 20G 0 100% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
udev 239M 4.0K 239M 1% /dev
tmpfs 50M 352K 50M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 248M 0 248M 0% /run/shm
none 100M 0 100M 0% /run/user
I want to know where is my disk space. and what is this proc folder?
Sorry for bad English.

  • Have you tried running the command inside the var and usr directories?

    As you have 5GB Var and 1.3GB usr folder

    You can see you have a 1GB Swapfile

    The proc folder contains information about processes and system information. You don’t really need to worry about it.

In some cases, it could be coming from Jenkins or Docker (or like that). To solve that, you should clean logs and set it’s size.
