[ovirt-users] Webadmin and API down with error 500 after updating from 4.4 to 4.5

Hello, today i updated from 4.4 to 4.5 and i am no longer able to access my oVirt Cluster. Accessing oVirt Web Interface fails with "500 - Internal Server Error". The API is also dead, My Backup Software and Foreman is no longer able to talk to oVirt. I rebooted the host an ran engine-setup again, it completed without issues but Engine ist still dead. If i ran it again, it tells me now that my cluster is not in global maintanance mode, but "hosted-engine --vm-status" tells me it is still in maintanance mode. one suspect thing i found in server.log is this: at org.springframework@5.0.4.RELEASE//org.springframework.jdbc.support.JdbcUtils.extractDatabaseMetaData(JdbcUtils.java:324) at org.springframework@5.0.4.RELEASE//org.springframework.jdbc.core.metadata.CallMetaDataProviderFactory.createMetaDataProvider(CallMetaDataProviderFactory.java:70) at org.springframework@5.0.4.RELEASE//org.springframework.jdbc.core.metadata.CallMetaDataContext.initializeMetaData(CallMetaDataContext.java:252) at org.springframework@5.0.4.RELEASE//org.springframework.jdbc.core.simple.AbstractJdbcCall.compileInternal(AbstractJdbcCall.java:313) at org.ovirt.engine.core.dal//org.ovirt.engine.core.dal.dbbroker.PostgresDbEngineDialect$PostgresSimpleJdbcCall.compileInternal(PostgresDbEngineDialect.java:106) at org.springframework@5.0.4.RELEASE//org.springframework.jdbc.core.simple.AbstractJdbcCall.compile(AbstractJdbcCall.java:296) at org.ovirt.engine.core.dal//org.ovirt.engine.core.dal.dbbroker.SimpleJdbcCallsHandler.getCall(SimpleJdbcCallsHandler.java:157) at org.ovirt.engine.core.dal//org.ovirt.engine.core.dal.dbbroker.SimpleJdbcCallsHandler.executeImpl(SimpleJdbcCallsHandler.java:134) at org.ovirt.engine.core.dal//org.ovirt.engine.core.dal.dbbroker.SimpleJdbcCallsHandler.executeReadList(SimpleJdbcCallsHandler.java:105) at org.ovirt.engine.core.dal//org.ovirt.engine.core.dao.TagDaoImpl.getAllForParent(TagDaoImpl.java:82) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.TagsDirector.addChildren(TagsDirector.java:116) at deployment.engine.ear.bll.jar//org.ovirt.engine.core.bll.TagsDirector.init(TagsDirector.java:75) ... 64 more 2022-04-26 12:32:32,129+02 INFO [org.wildfly.extension.undertow] (ServerService Thread Pool -- 60) WFLYUT0021: Registered web context: '/ovirt-engine/sso' for server 'default-server' 2022-04-26 12:32:32,137+02 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 Caused by: java.lang.IllegalStateException: WFLYEE0042: Failed to construct component instance Caused by: javax.ejb.EJBException: org.jboss.weld.exceptions.WeldException: WELD-000049: Unable to invoke protected void org.ovirt.engine.core.bll.TagsDirector.init() on org.ovirt.engine.core.bll.TagsDirector@21c5d21d Caused by: org.jboss.weld.exceptions.WeldException: WELD-000049: Unable to invoke protected void org.ovirt.engine.core.bll.TagsDirector.init() on org.ovirt.engine.core.bll.TagsDirector@21c5d21d Caused by: java.lang.reflect.InvocationTargetException Caused by: org.springframework.dao.InvalidDataAccessApiUsageException: Unable to determine the correct call signature - no procedure/function/signature for 'gettagsbyparent_id'"}} 2022-04-26 12:32:32,158+02 INFO [org.jboss.as.server] (ServerService Thread Pool -- 27) WFLYSRV0010: Deployed "ovirt-web-ui.war" (runtime-name : "ovirt-web-ui.war") 2022-04-26 12:32:32,159+02 INFO [org.jboss.as.server] (ServerService Thread Pool -- 27) WFLYSRV0010: Deployed "apidoc.war" (runtime-name : "apidoc.war") 2022-04-26 12:32:32,159+02 INFO [org.jboss.as.server] (ServerService Thread Pool -- 27) WFLYSRV0010: Deployed "restapi.war" (runtime-name : "restapi.war") 2022-04-26 12:32:32,159+02 INFO [org.jboss.as.server] (ServerService Thread Pool -- 27) WFLYSRV0010: Deployed "engine.ear" (runtime-name : "engine.ear") 2022-04-26 12:32:32,167+02 INFO [org.jboss.as.controller] (Controller Boot Thread) WFLYCTL0183: Service status report WFLYCTL0186: Services which failed to start: service jboss.deployment.subunit."engine.ear"."bll.jar".component.Backend.START: java.lang.IllegalStateException: WFLYEE0042: Failed to construct component instance WFLYCTL0448: 2 additional services are down due to their dependencies being missing or failed 2022-04-26 12:32:32,211+02 INFO [org.jboss.as.server] (Controller Boot Thread) WFLYSRV0212: Resuming server 2022-04-26 12:32:32,226+02 ERROR [org.jboss.as] (Controller Boot Thread) WFLYSRV0026: WildFly Full 24.0.1.Final (WildFly Core 16.0.1.Final) started (with errors) in 18363ms - Started 1670 of 1890 services (6 services failed or missing dependencies, 393 services are lazy, passive or on-demand) 2022-04-26 12:32:32,230+02 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0060: Http management interface listening on http://127.0.0.1:8706/management 2022-04-26 12:32:32,231+02 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0051: Admin console listening on http://127.0.0.1:8706 Anyone got an idea whats may be the reason? i am a bit lost here.
