      Observed on the MDT during weekend testing with an mixed I/O workload. I agree failure here shouldn't be fatal, however I'm not sure we should even bother telling the administrator. If it's true there's nothing that needs to be (or can be) done, then there's no point is logging this to the console. Changing it to a CDEBUG() would be preferable. If however the administrator needs to do something (which I don't believe is the case) that should be part of the message.
