I understand that this would involve a significant effort to fully port over and drop ceph-disk entirely, and I don't think that dropping ceph-disk in Mimic is set in stone (yet). We could treat Luminous as a "soft" deprecation where ceph-disk will still receive bug-fixes, and then in Mimic, it would be frozen - with no updates whatsoever. At some point a migration will have to happen for older clusters, which is why we've added support in ceph-volume for existing OSDs. An upgrade to Luminous doesn't mean ceph-disk will not work, the only thing that has been added to ceph-disk is a deprecation warning. > > -- > Piotr Dałek > piotr.dalek@xxxxxxxxxxxx > https://www.ovh.com/us/ > > -- > To unsubscribe from this list: send the line "unsubscribe ceph-devel" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
