Solution In Progress - Updated -

Issue

  • When I run oc adm diagnostics, I always get following Warning.
WARN: [DClu3004 from diagnostic MasterNode@openshift/origin/pkg/diagnostics/cluster/master_node.go:175]
Unable to find a node matching the cluster server IP.
This may indicate the master is not also running a node, and is unable
to proxy to pods over the Open vSwitch SDN.
  • Why this diagnostic produces this Warning message?
