I've got one physical host in a 3 host CentOS7.5 cluster that reports the following error several times a day

VDSM node3.example.com command Get Host Statistics failed: Internal JSON-RPC error: {'reason': '<Fault 1: "<type \'exceptions.AttributeError\'>:\'NoneType\' object has no attribute \'statistics\'">'}

Any ideas what the problem might be?

Hi,

I can make a wild guess[1], but let's try educated guesses first: could you please share the Vdsm logs around the time on which you see this error?

Thanks,

[1] It seems to me that a NIC card was removed from a VM during a statistic reporting cycle, or somehow failed to report stats. But really, is a wild guess.Let's look at the logs first.
