Hi Michael, Thank you for the detailed explanation. I was in the worst scenario where the database entries were purged and I had to manually re-create the DB entries and the ports. I successfully managed to insert the lines in the database and the amphoras were created.
Thanks a lot for the hints. I also increased the DB cleanup interval to 1 week.

This caused the load balancer amphora to be detected as failed and started the failover process which rebuilds the amphora, however this process also failed due to the wider infrastructure issues (Note, this is what I remember from the conversation. Correct the background if I am wrong). At this point the load balancers would be in a provisioning status of "ERROR", the amphora instances were likely deleted (depending on where the infrastructure issue impacted the failover process), and the amphora db records would be in the "DELETED" state. To make their situation worse, the DB cleanup cycle of the housekeeping process was set low (default is a week) and the amphora records were purged. This meant the customer data for the VIP address/ports was also purged. Recovery: If the database records were not purged, after the infrastructure issues are resolved, you can simply go into the octavia database and issue: update load_balancer set provisioning_status="ACTIVE" where provisioning_status = "ERROR"; This will restart the health manager expecting the amphora to report health heartbeats and the failover process with start again rebuilding the amphora. We have also recently added an admin API to trigger a failover manually (https://developer.openstack.org/api-ref/load-balancer/v2/index.html#failover-a-load-balancer). If your amphora records have been purged, you are in some pain (don't do this). This means that the VIP address and neutron port information for that VIP address are not available for the failover process to rebuild. In this case, before you start the above process you will need to recreate the amphora records from your logs, either adding the port information if the ports are still live in neutron, or creating replacement ports.
