Hi all, I’m new to ceph. I recently deployed a ceph cluster with cephadm. Now I want to add a single new OSD daemon with a db device on SSD. But I can’t find any documentation about this. I have tried: 1. Using web dashboard. This requires at least one filter to proceed (type, vendor, model or size). But I just want to select the block device manually. 2. Using ‘ceph orch apply osd -i spec.yml’. This is also filter based. 3. Using ‘ceph orch daemon add osd host:device’. Seems I cannot specify my SSD db device in this way. 4. On the target host, run ‘cephadm shell’ then ceph-volume prepare and activate. But ceph-volume seems can’t create systemd service outside the container like ‘ceph orch’ does. 5. On the target host, run ‘cephadm ceph-volume’, but it requires a json config file, I can’t figure out what is that. Any help is appreciated. Thanks. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
