Many thanks for creating the issue, and also thanks for the extensive and clear reply! In case somebody finds it useful, I am right now using the following incantation: lvs -o lv_tags | awk -vFS=, /ceph.osd_fsid/'{ OSD_ID=gensub(".*ceph.osd_id=([0-9]+),.*", "\\1", ""); OSD_FSID=gensub(".*ceph.osd_fsid=([a-z0-9-]+),.*", "\\1", ""); print OSD_ID,OSD_FSID }' | sort -n | uniq which runs very fast and directly returns the parameters to be consumed by "ceph-volume lvm activate" (i.e. OSD-ID and OSD-FSID). Or course, use that at your own risk until a good implementation in ceph-volume is available. Cheers, Oliver
