"As part of an upgrade we have reinstalled it."
What does "reinstalled" here means?
From the attached error it seems that during the reinstall you purged some of the db like nova but did not purge some other db like placement. So nova-compute re-creates the compute node and then the compute resource provider (RP) in placement. The new compute node uuid will be the uuid of the RP and the hypervisor hostname will be the name of the RP. As the compute node is re-created it gets a new uuid but the hostname remains the same. So placement rejects the RP creation as both the uuid and the name should be unique.
