[ovirt-users] Re: Replace bad Host from a 9 Node hyperconverged setup 4.3.3

Ok I have tried reinstalling the server from scratch with a different name and IP address and when trying to add it to cluster I get the following error: Event details ID: 505 Time: Jun 10, 2019, 10:00:00 AM Message: Host myshost2.virt.iad3p installation failed. Host myhost2.mydomain.com reports unique id which already registered for myhost1.mydomain.com I am at a loss here, I don't have a brand new server to do this and in need to re-use what I have. *From the oVirt engine log (/var/log/ovirt-engine/engine.log): * 2019-06-10 10:57:59,950-04 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-37744) [9b88055] EVENT_ID: VDS_INSTALL_FAILED(505), Host myhost2.mydomain.com installation failed. Host myhost2.mydomain.com reports unique id which already registered for myhost1.mydomain.com So in the /var/log/ovirt-engine/host-deploy/ovirt-host-deploy-20190610105759-myhost2.mydomain.com-9b88055.log of the ovirt engine I see that the host deploy is running the following command to identify the system, if this is the case then it will never work :( because it identifies each host using the system uuid. *dmidecode -s system-uuid* b64d566e-055d-44d4-83a2-d3b83f25412e Any suggestions?
