Expected results:
host destroyed/deleted
Additional info:
as a workaround you can delete from psql tables
#su postgres
#psql foreman
delete from katello_subscription_facets where host_id=(select id from hosts where name='host.example.test');
delete from katello_content_facets where host_id=(select id from hosts where name='host.example.test');
than
Host.find_by_name("host.example.test").destroy
will pass successfully.
In Satellite 6.2, hosts should not be deleted using the procedure above. One of the features introduced in the release is referred to as "Host Unification". With that feature, a host can include subscription (candlepin) and content (pulp) facets, which means additional objects are stored in the backend services. For this reason, errors like the one above are expected as a means to protect the user.
Is there a reason the host is being destroyed with "Host.find_by_name("host.example.test").destroy" as opposed to being destroyed through the UI/CLI/API? If it is failing there, is there anything in foreman-tasks or logs indicating why it is failing?
Comment 2Patrick C. F. Ernzer

for me, the reason to want manual deletion is:
Katello::Resources::Candlepin::CandlepinResource: 404 Resource Not Found {"displayMessage":"Runtime Error RESTEASY001185: Could not find resource for relative : /consumers//entitlements of full path: https://localhost:8443/candlepin/consumers//entitlements at org.jboss.resteasy.core.registry.PathParamSegment.matchPattern:209","requestUuid":"eccbdfe4-f385-4724-9b5f-1f2a787e5a80"} (GET /candlepin/consumers//entitlements)
The proper way to do this would be:
ForemanTasks.sync_task(::Actions::Katello::Host::Destroy, Host.find_by(:name => "host.example.com"))
If this fails for some reason you could use:
host = Host.find_by(:name => 'host.example.com')
host.subscription_facet.try(:destroy! ) if host
host.content_facet.try(:destroy!) if host
host.destroy if host
however this could leave bad data in the backend. This should be able to be fixed with the clean_backend_objects script as part of https://bugzilla.redhat.com/show_bug.cgi?id=1405500
Closing as WONT_FIX
