It seems we lost the PDNS database content with the recent reimages of cloudservices2004-dev/2005-dev nodes into Debian 12 Bookworm.
There should be at least two procedures to restore the data:
- have designate force-recreate it. The data is originally stored in the openstack BD (galera), but designate wont inject it into PDNS unless there is an update in the records. How to force-do-it is unknown at the moment
- restore a pdns database backup. Given the hosts were reimaged, restoration might a be a bit trickier.
