Hello, If you mean 3x replication in total over 2 racks/failure domains. that has of course come up several times in the past, for example: --- https://www.mail-archive.com/ceph-users@xxxxxxxxxxxxxx/msg19140.html http://lists.opennebula.org/pipermail/ceph-users-ceph.com/2014-September/043039.html --- I don't think you can do this via the CLI, the simple in "create-simple" is a clear hint. I you actually mean 3x replication PER RACK, so 6x replication total, that's just a variation of the of the above, using a pool with 6 replicas.
