Do you mean RHCS 5 to 6? The recommended and documented upgrade path is actually RHCS 5 to 7 after upgrading RHCS 5 nodes to RHEL 9. Did you upgrade cephadm and cephadm-ansible packages before running the preflight playbook? Regards, Frédéric. ________________________________ De : Alex <mr.alexey@xxxxxxxxx> Envoyé : mercredi 16 avril 2025 20:03 À : Frédéric Nass Cc: ceph-users Objet : Re: Preflight Playbook I was upgrading from Ceph 5 to 6 on RHEL 9.
