Doc Text:	Cause: The device name provided by Cinder was being used for volume mounting into a pod, however, the device name provided by Cinder is unreliable for the actual mounting. Consequence: Some Cinder volumes are not mounted into a pod. A message like the one below shows up in logs: I1220 10:46:05.596012 1960 operation_executor.go:649] Entering MountVolume.WaitForAttach for volume \"kubernetes.io/cinder/c1c7b12e-bcfb-4dcb-9a39-c585d7ede52e\" (spec.Name: \"@kibana-highlighted-field@quay@/kibana-highlighted-field@-pv\") pod \"19abf22b-c6bd-11e6-9e19-fa163e7ff93a\" (UID: \"19abf22b-c6bd-11e6-9e19-fa163e7ff93a\") DevicePath: \"/dev/sdd\" Fix: Detection is performed. The detection uses Cinder ID. Result: Cinder volumes are being reliably mounted into appropriate pods.
