Hi, Yesterday I had to replace a couple of failed/failing OSDs using Ceph Orchestrator (on Ceph 18.2.1), but I've made a mistake and I removed them without the "--replace" option. I wasn't able to find the correct option (if any) to specify an id for newly created OSD. The closest one was "osd_id_claims", but if I understood correctly is used to claim an OSD id which is still in the crush map (as destroyed). Am I missing something obvious or with Ceph orchestrator there are non way to specify an id during the OSD creation? Cheers Iztok P.S. At the end I (re)added the OSD in the correct order, starting with the lowest id device. -- Iztok Gregori ICT Systems and Services Elettra - Sincrotrone Trieste S.C.p.A. http://www.elettra.eu
