Nginx + php5-fpm + Symfony2 = "File not found."

SUMMARY: My issue was wrong file permissions. The official symfony2 config for nginx is OK. I moved my files to an NTFS Storage drive, and it seems during the move file permissions were changed.

• chown loostro:www-data -R /media/Storage/project - change owner to loostro and group to www-data (loostro is my user under which I develop the app, php5-fpm runs as www-data), recursively
• chmod 755 -R /media/Storage/project - change file permissions for project to rwx (owner) rx (group, other), recursively
• cd /media/Storage/project enter my project directory
• chmod 775 -R app/cache app/logs web/uploads private/uploads - change file permissions for uploadable directories rwx (owner,group) and rx (other), recursively
• chmod g+s -R /media/Storage/project - keep user and group & file permissions for newly created files in directories, recursively
