Dear list, we are new to ceph and we are planning to install a ceph cluster over two datacenters. The situation is: DC1: 2 racks DC2: 1 racks We want to have one replica per rack and more generally two replicas in the first DC and one in the other one. So now we are stuck on the crushmap: how to force the cluster to put two replicas in the first dc? Is that related to th bucket's weight? These are the buckets we are using: 1) DC 2) Rack 3) Server Do you think is enough? Any kind of help is really appreciated.
