Because when you upgrade to 12.2.2 suddenly existing integrations will have deprecation warnings being thrown at them while they haven't upgraded to a new major version. ceph-volume has been present since the very first release of Luminous, the deprecation warning in ceph-disk is the only "new" thing introduced for 12.2.2. > > As ceph-deploy doesn't support ceph-disk either I don't think it's a good idea to deprecate it right now. ceph-deploy work is being done to support ceph-volume exclusively (ceph-disk support is dropped fully), which will mean a change in its API in a non-backwards compatible way. A major version change in ceph-deploy, documentation, and a bunch of documentation is being worked on to allow users to transition to it. > > How do others feel about this? > > Wido > >> We are strongly suggesting using ceph-volume for new (and old) OSD >> deployments.
