Graphite SQLite3 DatabaseError: попытка записи базы данных только для чтения

Запуск графита под apache httpd, с базой данных slqite, у меня есть правильные разрешения для папки

[root@liaan55 httpd]# ls -ltr /var/lib | grep graphite
drwxr-xr-x. 2 apache        apache        4096 Aug 23 19:36 graphite-web

и

[root@liaan55 httpd]# ls -ltr /var/lib/graphite-web/
total 68
-rw-r--r--. 1 apache apache 65536 Aug 23 19:46 graphite.db

syncdb, похоже, тоже все прошло нормально

[root@liaan55 httpd]# sudo -su apache
bash-4.1$ whoami

You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no): yes
Username (leave blank to use 'apache'): root
E-mail address: a.b@c.com
Password: 
Password (again): 
Superuser created successfully.

а файл local-settings.py выглядит следующим образом

STORAGE_DIR = '/var/lib/graphite-web'

INDEX_FILE = '/var/lib/graphite-web/index' 

DATABASES = {
    'default': {
        'NAME': '/var/lib/graphite-web/graphite.db',
        'ENGINE': 'django.db.backends.sqlite3',
        'USER': '',
        'PASSWORD': '',
        'HOST': '',
        'PORT': ''
    }
}

Я все еще получаю эту ошибку

не уверен, чего не хватает в этой конфигурации
