Hi Murilo, This is briefly referred to by https://docs.ceph.com/en/octopus/rados/deployment/ceph-deploy-mon/, but in order to avoid split brain issues it's common that distributed consensus algorithms require a strict majority in order to maintain quorum. This is why production deployments of mons should usually be an odd number: Adding one more mon to an odd number (to end up with an even number) doesn't provide materially better availability.
