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?
