.. index:: sync

=============================
Synchronize OpenStack objects
=============================


Fleio is storing a copy of the OpenStack objects in its database. This cache allows Fleio to
be faster and puts less load on the OpenStack API.


.. index:: fleio service, updated

fleio service
=============

The ``fleio`` daemon connects to OpenStack queues and gets push notifications when an OpenStack objects (instances, volumes, networks etc.) are created, modified or deleted.

``fleio`` service processes these notifications and updates the Fleio database.

.. index:: automatic sync

Automatic synchronization
=========================

The synchronization process is running automatically after saving the initial OpenStack configuration and it will populate the Fleio database with OpenStack objects.

.. index:: manual sync

Manual synchronization
======================

If you want to do a manual synchronization, this can be done by running the ``fleio sync``.

.. code-block:: bash

    fleio sync

After the synchronization is finished, it's also useful to restart the ``fleio`` service:

.. code-block:: bash

    systemctl restart fleio
