Majid, Check out the install guide for Ubuntu using Cephadm here: https://docs.ceph.com/en/latest/cephadm/install/ Basically install cephadm using apt, then use the Cephadm bootstrap command to get the first mon up and running. For additional hosts, make sure you have them in the hosts file and also make sure you do this step, adding the Ceph ssh keys, before attempting to add new hosts: https://docs.ceph.com/en/latest/cephadm/host-management/#cephadm-adding-hos… Once the first mon/mgr is up (after the bootstrap) you can do most of what you need via the web interface, adding hosts/osd’s etc. You will have fun and games with it, the email list and iirc channels are very active and helpful. Just be aware of the many different deployment methods of Ceph e.g. Cephadm, ansible, juju etc. Also whether native or container based install. The direction of travel appears to be with Cephadm and containers. The documentation you’ll find out on the web may be referring to a different deployment method or tools compared to what you’ve done. Even the official docs can be a bit misleading sometimes. I’m pretty new to Ceph myself and deployed onto Ubuntu 20.04 LTS and Ceph 15.2.8/9 on containers after using Ceph on a Proxmox cluster. It’s in production now and seems to work well. Break it and fix it a few times....you’ll get the hang of it.
