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 detailsID: 505Time: Jun 10, 2019, 10:00:00 AMMessage: Host myshost2.virt.iad3p installation failed. Host myhost2.mydomain.com reports unique id which already registered for myhost1.mydomain.comI 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.comSo 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

Server having gluster volume.Note: the server was already reinstalled so gluster will never see the volumes or bricks for this server.I will rename the server to myhost2.mydomain.com and try to replace the bricks hopefully that might work, however it would be good to know that you can re-install from scratch an existing cluster server and put it back to the cluster.Still doing research hopefully we can find a way.thanks againAdrianOn Fri, Jun 7, 2019 at 2:39 AM Leo David <leoalex@gmail.com> wrote:You will need to remove the storage role from that server first ( not being part of gluster cluster ).I cannot test this right now on production, but maybe putting host although its already died under "mantainance" while checking to ignore guster warning will let you remove it.Maybe I am wrong about the procedure, can anybody input an advice helping with this situation ?Cheers,LeoOn Thu, Jun 6, 2019 at 9:45 PM Adrian Quintero <adrianquintero@gmail.com> wrote:I tried removing the bad host but running into the following issue , any idea?Operation Canceled

One of my hosts is completely dead, I need to do a fresh install using ovirt node iso, can anybody point me to the proper steps?
thanks,
