The best questions are the ones that one can answer oneself. The great documentation on https://docs.ceph.com/en/latest/dev/ceph-volume/lvm/ gives the right pointers. The right search term is "lvm list tags" and results into something like this: [15:56:04] server20.place6:~# lvs -o lv_tags /dev/sda: open failed: No medium found /dev/sdb: open failed: No medium found LV Tags ceph.block_device=/dev/ceph-26fdb7c4-17af-42af-8353-06d95b0071c7/osd-block-bb63e9b6-b2d7-40d1-83ee-815262ae8b45,... If anyone is interested in upstream ceph-volume support for non-systemd Linux distributions to activate the ceph-osds, let me know. In any case, we'll publish our new style scripts on [0].

Good morning,
is there any documentation available regarding the meta data stored within LVM that ceph-volume manages / creates?
My background is that ceph-volume activate does not work on non-systemd Linux distributions, but if I know how to recreate the tmpfs, we can easily start the osd without systemd.
Any pointers in the right direction are appreciated.
Best regards,
Nico
