[ceph-users] How to administer Ceph from any node without bootstrap dependency

Hi all, I am currently deploying a Ceph cluster with cephadm on 3 nodes with MON, MGR, and MDS roles. OSDs will be added later. My goal is for these 3 nodes to be fully interchangeable, with the ability to administer the cluster from any of them without risk if a node fails. I have identified that the solution involves synchronizing /var/lib/ceph/ (excluding the bootstrap file) across all nodes. However: - Is this the right approach to achieve this goal? - Which tool should I use for reliable bidirectional synchronization? - What are the potential risks (conflicts, corruption) and precautions to take? Have you implemented such a configuration in production before? Thank you for your advice. -- Michel
