Hi all, I had a question, I'm in the middle of a new ceph deploy cluster and I've 6 OSD servers between two racks, so rack1 would have osdserver1,3 and 5, and rack2 osdserver2,4 and 6. I've edited the following crush map and I want to know if it's ok and also if the objects would be stored one on each rack-host. So, if I lost one rack, I had one copy on the other rack/server:
