I just can't delete the folder under root (it says that resource/device is busy), but lsof and fuser tell me nothing. The folder is located in the depth of /var/www/... and I tried to delete it after I stop apache2 and nginx.

You can use:
sudo lsof +D /var/www/dir_name
Once you know which processes have files open, you can exit those apps, or kill them with the kill
command.
If you had a partition mounted to that point, you should umount
first.
