Sync EFA with Neutron

The OpenStack integration enables you to sync all entries from Neutron to EFA.

About this task

When EFA goes out of sync with Neutron configuration, run efa-sync to sync all entries from Neutron to EFA. For example, if there is a network and associated ports that are present on Neutron but are not present on EFA, running efa-sync creates the entities on EFA. Similarly, if there are stale entries on EFA, they are cleaned up.

You can display summary or detailed information about entities that are out of sync between Neutron and EFA configurations.

  2. Display summary information about entities that are out of sync between Neutron and EFA configurations.

    Journal entries that are in a failed state are cleared from the journal list if efa-sync is successful. If the efa-sync run fails (complete failure or partial failure), the failed journal entries are not cleared.

  3. Display summary or detailed information about those entities that are out of sync between Neutron and EFA configurations. 
    $ efa-sync check-summary
