Thank you guys, can do this online or need any outage?
I think it is safe to run these commands while the nova services are up. However if you have a lot of data to move and then delete that can cause extra DB load. Cheers, gibi

Hi,
We have a cluster where the user continuously spawn and delete servers which makes the db even in compressed state 1.1GB. I’m sure it has a huge amount of trash because this is a cicd environment and the prod just uses 75MB. How is it possible to cleanup the db on a safe way, what should be the steps?
From Nova perspective you can get rid of the data of the already deleted instances via the following two commands:
nova-manage db archive_deleted_rows nova-manage db purge
Cheers, gibi
