100% used disk - Ubuntu 14.04

Hi, I have a droplet, and I was turning crazy looking for disk usage, I tried with:

du -d 5

and many other commands… and I didn´t find anything.

The message:

# df
Filesystem     1K-blocks     Used Available Use% Mounted on
/dev/vda1       20511356 19447420         0 100% /

But only rebooting system:

~$ df
Filesystem     1K-blocks    Used Available Use% Mounted on
/dev/vda1       20511356 2884808  16561592  15% /

Anyone knows what it happens?

I feel is like an issue with digitalocean droplet but I don´t find any explanation.



If this occurs again I would recommend first checking your /tmp folder. If something is writing a large amount of data there it could use up your disk but since /tmp is usually cleared on boot this could account for the used space dropping so dramatically after a reboot.

If you don’t find anything there I would recommend opening a ticket with our support team so they can investigate further.

What all have you or are you running on the Droplet? That’d provide some insight so that we can better help you out :-) (if DigitalOcean hasn’t already via ticket).
