All, We have built a new oVirt cluster from scratch. We used the 4.4.4 installer released in December 2020. When deploying the engine we had the wizard create a Gluster volume for the engine on three hosts. All went well and the cluster is starting to take shape. When starting the engine we do see the following error each time the engine is started in /var/log/ovirt-engine/engine.log: 2021-02-23 08:06:09,208+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-33) [4293beae] EVENT_ID: SYSTEM_CHANGE_STORAGE_POOL_STATUS_PROBLEMATIC(980), Invalid status on Data Center Default. Setting status to Non Responsive. Also when navigating in the engine web-ui to Compute -> Data Centers -> Default and check the events an event of id 980 is shown with the message: “Invalid status on Data Center Default. Setting status to Non Responsive.”. The date/time matches when the error is shown in the engine log. The datacenter overview does not show any warnings or errors and lists the Default datacenter as status Up. An interesting observation is that the cluster overview does have a status column on the far left, but the status is not mentioned. The field underneath the status heading is empty. Could that be the unknown status that the data center refers to? How could we investigate this further? The storage volumes do not show any issues and the cluster seems to function okay (it has not been used a lot yet as it has been built yesterday/today), but the error message does sound like something we need to get out of the way before we put the actual workload on it.
