Fixed In Version: ceph-17.2.6-267.el9cp
Doc Type: Enhancement
Doc Text:
”ceph orch set-unmanaged" and "ceph orch set-managed" commands are now available in Ceph 6.1z9 version Previously, moving services between managed and unmanaged states required manual modification of the specification files. With this enhancement, the ceph orch set-unmanaged and ceph orch set-managed commands are introduced. These commands allow services to transition between managed and unmanaged states without modifying the specification files. When a service is in the unmanaged state, cephadm will not automatically add or remove daemons or perform other background tasks. The primary use case for this enhancement is to move OSD services to the unmanaged state, ensuring that no new OSDs are deployed based on the OSD specification.

Comment 1 Adam King 2024-06-06 18:39:27 UTC 
This has already been backported to quincy in the upstream via https://github.com/ceph/ceph/pull/50897 so it should make its way into the downstream on the next rebase we do.

Hi Adam,

    Thanks for the information. The target release I assigned is 6.1z7. Please assign the correct target release if it is not 6.1z7.
