As part of my development environment, I import a dump from our existing 1.9 deployment and upgrade through to 1.11. However, the hundreds of hosts cluttering up the Dev environment is problematic and makes my testing plan more complex than needed.

This dev Foreman does not have all of the providers present in the production environment, and those providers are neither needed nor desired.

When I attempt to disassociate the unwanted production hosts from my dev foreman that would be tied to the vsphere provider in the Production environment, the disassociation fails with a 302 but the Foreman Web UI reports success. Following this, the hosts are not removed from the host list as one might expect. The only change I can confirm is being made is that the fqdn value is being populated with the host's fqdn in the 'value_lookup_matcher' in the hosts table.

When I attempt to delete the host after the supposedly-successful disassociation, I get the following error and the host is still not removed from the host list.
