+ Removed the hard coding of osd_pool_default_min_size. Setting this value
+ to 1 can result in data loss in operating production deployments. Not
+ setting this value (or setting it to 0) will allow ceph to calculate the
+ value based on the current setting of osd_pool_default_size. If the
+ replication count is 3, then the calculated min_size is 2. If the
+ replication count is 1, then the calcualted min_size is 1. For a POC
+ deployments using a single OSD, set osd_pool_default_size = 1. See
+ description at http://docs.ceph.com/docs/master/rados/configuration/pool-pg-config-ref/
+ Added CephPoolDefaultSize to set default replication size. Default value is 3.
