I haven't tried to downgrade, but perhaps the following steps might help. ceph orch daemon redeploy <daemon_name> --image quay.io/ceph/ceph:v20.2.0
-or- ceph config set global container_image quay.io/ceph/ceph:v20.2.0 Then do each daemon individually ceph orch apply mgr --image quay.io/ceph/ceph:v20.2.0 Get Outlook for Android<https://aka.ms/AAb9ysg> ________________________________ From: Marek Szuba via ceph-users <[email protected]> Sent: Wednesday, December 3, 2025 8:50:43 AM To: [email protected] <[email protected]> Subject: [ceph-users] Re: Updating cephadm-managed Tentacle cluster from RC to production This is an external email.

Same as without the restriction - with "--ceph-version 20.2.0" the upgrade fails immediately with "ceph cannot downgrade to a dev release", with "--image quay.io/ceph/ceph:v20.2.0" the "cannot downgrade" appears in the upgrade status. -- MS _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected] This message and its attachments are from Data Dimensions and are intended only for the use of the individual or entity to which it is addressed, and may contain information that is privileged, confidential, and exempt from disclosure under applicable law.
