Synchronize OpenStack objects¶
This page only applies for Fleio OpenStack Edition or Fleio Full Edition.
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.
fleio-updated-1 container connects to an OpenStack messaging queue and receives notifications when OpenStack
objects (like instances, volumes or networks) are created, modified or deleted.
fleio-updated-1 container processes these notifications and updates the Fleio database.
The synchronization process is running automatically after saving the initial OpenStack configuration, and it will populate the Fleio database with OpenStack objects.
You can start a sync from the staff web application:
OpenStack and click
Sync button from the
bottom-right corner of the screen.
Or by using the command line:
The manual synchronization is affected by OpenStack sync settings.
During synchronization Fleio will attempt to make a copy of all supported OpenStack objects into Fleio database. However, there are some special cases where objects are treated differently or even ignored.
New in version 2022.05.1.
During various operations (e.g. volume backup) Cinder may create temporary volumes that do not count against quota and for whom no notifications are sent. This volumes will not be added to Fleio database during normal operation however if you trigger a sync during a volume backup for example then the temporary volume may be added to the Fleio database until a future sync will remove it.
To prevent this we check consumes_quota attribute for volumes, if consumes_quota is False the volume will be ignored during sync process.
Note that consumes_quota attribute is only available for Cinder API version 3.65 or greater, if this API version is not available in your OpenStack deployment we provide a workaround for volume backups (see Exclude backup volumes from sync).
