From what I understand, umask is the bitwise inverse of permissions and a nonzero umask blocks you from setting certain permissions. In other words, umask=000 allows you to set any permissions up to 777. I'd set it at least umask=033 so root could have total access (as long as permissions are also set properly, eg. 7xx).
This permissions stuff can easily reach out and bite you.
