cluster and public network configuration.

[Roman Alekseev <rs.alekseev@gmail.com>]

Hi,

I've configured my ceph cluster to use cluster and public networks, but 
looks like this configuration doesn't work correctly because when rados 
bench returns the following test's result:

  Maintaining 16 concurrent writes of 4194304 bytes for at least 10 seconds.

My question is: How to set up cluster network correctly?

Thanks
