- node1 : MON + 6 OSD - node2 : 6 OSD Ceph monitors number need to be an odd number in order to satisfy the quorum needs, thus if you don't want to have a SPOF with only one mon (although its fine for testing purpose), you should add a third server (could be less powerfull if it only act as a mon). As of my comprehension, the best way to start a Ceph cluster is to have at least 3 nodes. Cheers > > > The machines have: 6 x 1TB HDDs, 2 x 8-core processors, and 128GB > Memory.
