You can't append any more because your account is over quota.

Yes.  The file doesn't exist and you don't have permission to create 
/root/tmp (write permission on /root).

If you create /root/tmp as root and chmod it to 666 then 'sudo yes > 
/root/tmp' will work.  So will 'yes > /root/tmp'.

Since you don't own the file, will it count against your quota?  I don't 
know.
