We have to implement the alembic db migration

cd /usr/lib/python2.7/dist-packages/neutron_lbaas/db/migration/alembic_migrations/$

we need a alembic.ini configuration file. What I did is to copy this file from the neutron package:

cp /usr/lib/python2.7/dist-packages/neutron/db/migration/alembic.ini .

At this point we can start a new alembic migration

Replication Notes

Assumption: You have two clusters, access to both, and a pool that exists in both clustsers and you wish to replicate some or all images in that pool to the other cluster.

Mirroring in both directions is required for Cinder to properly implement failover and failback.

Make sure you have the rbd-mirror package installed.

    Check if namespace exists before exec commands
    
    If a neutron router has no ports defined, its namespace is deleted.
    It is required to check if the namespace exists before calling
    exec commands against the namespace.
    It is not enough for the string of the namespace uuid to be defined,
