hello, I have a problem with oVirt in my home lab - probably after power outage(all hypervisors + hosted engine appliance went down) Current state: hosted engine appliance is starting from OS perspective, however some jboss related stuff seems to be malfunctioning. /var/log/ovirt-engine: grep ERROR engine.log | tail -n2 2020-03-17 17:35:52,769+01 ERROR [org.ovirt.engine.core.bll.network.macpool.MacPoolPerCluster] (ServerService Thread Pool -- 50) [] Error initializing: Duplicate key VM [***some_vm_name***] 2020-03-17 17:35:52,922+01 ERROR [org.ovirt.engine.core.bll.Backend] (ServerService Thread Pool -- 50) [] Error during initialization: javax.ejb.EJBException: java.lang.IllegalStateException: WFLYEE0042: Failed to construct component instance grep ERROR server.log | tail -n2 2020-03-17 17:36:00,755+01 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "engine.ear")]) - failure description: {"WFLYCTL0080: Failed services" => {"jboss.deployment.subunit.\"engine.ear\".\"bll.jar\".component.Backend.START" => "java.lang.IllegalStateException: WFLYEE0042: Failed to construct component instance 2020-03-17 17:36:01,021+01 ERROR [org.jboss.as] (Controller Boot Thread) WFLYSRV0026: WildFly Full 14.0.1.Final (WildFly Core 6.0.2.Final) started (with errors) in 56493ms - Started 1492 of 1728 services (6 services failed or missing dependencies, 387 services are lazy, passive or on-demand) probably because of that I am receiving 503 while connecting to webgui grep 503 /var/log/httpd/access_log | tail -n1 ***some_intenal_ip*** - - [18/Mar/2020:13:01:26 +0100] "GET /ovirt-engine/services/health HTTP/1.1" 503 299 "-" "Python-urllib/2.7" Ovirt Engine version: ovirt-engine-4.2.8.2-1.el7.noarch if you could help me or at least give some hints/advice then it could be great. I tried to google it however without any luck. thanks in advance. btw - in this case ovirt-engine service status is "fine" when checking via systemctl - not sure if it should reflect state "active (running)" when it is working partially
