[jboss-jira] [JBoss JIRA] (WFCORE-5121) Unable to add a new server in a server-group of older EAP 7 host controller that is managed by a newer EAP 7 Domain Controller

Unable to add a new server in a server-group of older EAP 7 host controller that is managed by a newer EAP 7 Domain Controller ------------------------------------------------------------------------------------------------------------------------------ Key: WFCORE-5121 URL: https://issues.redhat.com/browse/WFCORE-5121 Project: WildFly Core Issue Type: Bug Components: Server Reporter: Bartosz Spyrko-Smietanko Assignee: Bartosz Spyrko-Smietanko Priority: Major Labels: customer, support-case-open I followed EAP 7.2 documentation [1]  and have successfully configured a JBoss EAP 7.2.8 Domain Controller to Administer a JBoss EAP 7.1.6 Host Controller. I have followed all the steps listed in there and believe the configuration is OK. Both the master DC and host slave hosts started fine. The remote slave host "SlaveEAP71" registered successfully into the EAP 7.2.8 DC Cf.>>> {code:java} ... [Host Controller] 20:34:54,387 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0025: JBoss EAP 7.2.8.GA (WildFly Core 6.0.27.Final-redhat-00001) (Host Controller) started in 6162ms - Started 81 of 83 services (23 services are lazy, passive or on-demand) ... [Host Controller] 20:35:12,457 INFO [org.jboss.as.domain.controller] (Host Controller Service Threads - 9) WFLYHC0019: Registered remote slave host "SlaveEAP71", JBoss JBoss EAP 7.1.6.GA (WildFly 3.0.21.Final-redhat-00001)  ... {code}   However, when trying to add a new server in a server-group with profile copied from the older EAP 7.1.6 host , I'm not able to have this working. The following error always comes up on CLI started on EAP 7.2.8 Domain Controller {code:java} [domain@10.44.130.73:9990 /] /host=SlaveEAP71/server-config=SlaveJvm-EAP71:add(group=ServerGroup-eap71) { "outcome" => "failed", "result" => {}, "failure-description" => {"host-failure-descriptions" => {"SlaveEAP71" => "WFLYHC0201: Error synchronizing the host model with the domain controller model with failure : WFLYDC0075: Cannot synchronize the model due to missing extensions: [org.wildfly.extension.microprofile.opentracing-smallrye, org.wildfly.extension.microprofile.config-smallrye, org.wildfly.extension.ee-security]."}}, "rolled-back" => true } [domain@10.44.130.73:9990 /] {code}   This is a the server group defined in the Host master domain.xml : {code:java} <server-groups>     <server-group name="ServerGroup-eap71" profile="full-ha-eap71">         <socket-binding-group ref="full-ha-eap71-sockets"/>      </server-group> </server-groups> {code}   The profile="full-ha-eap71" is copied from the EAP 7.1.6 domain.xml and added into EAP 7.2.8 domain.xml, as well as the "full-ha-eap71-sockets" socket-binding-group.   *NOTE: The same issue does also happen with EAP 7.3.1 running as master host DC and EAP 7.1.6 as host slave.*   [1] [https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_ap...]
