Hello everyone, Environment is 4.15.0 ACS on Centos 7 in HA setup on 3 node galera cluster managing XCP-NG hosts. Today I performed upgrade of ACS from to 4.15.2 as per this guide http://docs.cloudstack.apache.org/en/latest/upgrading/upgrade/upgrade-4.15.html
After upgrade the management service is running but GUI gives this error: HTTP ERROR 503 Service Unavailable URI: /client/ STATUS: 503 MESSAGE: Service Unavailable SERVLET: - In management-server.log I see this error pops after starting the service: 2021-10-18 11:04:55,142 ERROR [c.c.u.DatabaseUpgradeChecker] (main:null) (logid:) Unable to upgrade the database com.cloud.utils.exception.CloudRuntimeException: 4.15.1.0XenServer SystemVm template not found. Cannot upgrade system Vms I do registered the template upload as per the guide steps. Any advice? Best regards, Jordan
