@Tom-Elliott I’m seeing this message on Storage Nodes at work - I can assure you I run everything as root. Here’s my thread where this error shows up, if it helps at all:
https://forums.fogproject.org/topic/8376/storage-nodes-stop-reporting-after-a-while/24
Also - an earlier picture posted by the OP makes me think if this isn’t EXACTLY the same issue I had in that above thread. Because some of his nodes were not reporting their version or interface names - exactly as my issue is.
