Yes, that's it. One PV+VG for each drive, with one LV. I've done that. I don't have my conf at hand, but it's sort of : On 2 SSD, one VG + one LV for WAL/DB for each HDD. One VG + one LV on each HDD. I provisionned them with an ansilble playbook using standard LVM modules. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
