Hi Massimo, Regarding bluestore bugs in 18.2.5 and 18.2.6, if you did not encounter them during the upgrade I think you should be relatively safe for now but can't tell for sure. You should upgrade to 18.2.7 as soon as you can.
Regarding AlmaLinux, you could try to build openssl-libs v3.4 or download and install openssl-libs v3.5 on the new servers and see if you can install and run Ceph v18.2.7 on them. OR (better) Unless you have strong operational concerns about using containers (e.g. you operate tens of clusters with your own automation tools and don't want to change your operational methods) you could switch to containers with cephadm adopt [1] or cephadm-adopt.yml playbook [2] if you're using ceph-ansible. Containers have been around for a long time now and it's the only supported method for deploying and operating downstream Ceph since Red Hat Ceph Storage 5 (Pacific). It's mature, stable, eases and accelerates a lot of operations (e.g. upgrades, adding/removing OSDs, MONs, etc.) and offers new possibilities (e.g running multiple RGWs on the same host).
