Hi Rajesh, here's the error. It happens when we try to add a template. We need to find a way to replace this with a dummy implementation.
[java] WARN [storage.download.DownloadMonitorImpl] (http-8080-5:) There is no secondary storage VM for secondary storage host nfs://10.73.76.36/export/secondary The fake secondary storage VM exists and is shown as in "Running" state in the admin panel. Thanks!
