* ceph-osd-replication-count | int

  Default: 3

  This value dictates the number of replicas ceph must make of any
  object it stores withing the cinder rbd pool. Of course, this only
  applies if using Ceph as a backend store. Note that once the cinder
  rbd pool has been created, changing this value will not have any
  effect (although it can be changed in ceph by manually configuring
  your ceph cluster).
