Go to /var, /opt and ~ to try the above

When your VM has run out of space 

find / -xdev -type f -size +100M

Decrease Journal Size#

If you run this and see references to the journal

/var/log/journal/8cbcddca1a876f4a6d2ebcc457e51618/system@25b4ea9a10124cd8b35f78511812b1a0-0000000000190463-0005e78573829d9f.journal

Systemd might be using a lot of space.

Check and decrease the size with:

sudo journalctl --disk-usage
sudo journalctl --vacuum-size=128M
sudo journalctl --verify

Decrease Git Repo Size#

From time to timea git repo may gather a lot of garbage

If you have an entry like this in the above:

/var/www/my_site/.git/objects/pack/pack-b6a7cb4684eaeab4006353c0381fb26decc72759.pack

You might want to go garbage collection:

cd /var/www/my_site
git gc
