Incorrect available space output of df after deleting huge file

  • 772

I've ran out of space and decided to free memory by deleting virtual machine files holding 3.8G. After that I see strange df output:

$ df -h | grep 'sda2\|Use'
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2       110G  107G     0 100% /

Where are these available gigabytes that I've freed? System is unusable but it should be at least few gigabytes of space.

Tried to reboot, checked free inodes, tried to look at sudo lsof +L1 output - nothing.

Could anybody help?

UPD for @Katu:

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            3.9G     0  3.9G   0% /dev

  1. If you haven't delete your virtual machine from command line, you have to empty the trash to see change in df -h.

    You could also check the biggest files in your system to delete or backup.

    find . -type f -size +100M

    Or whatever size you want.
