So that's a bug ;) https://github.com/ceph/ceph/blob/master/src/ceph-volume/ceph_volume/devices... This doesn't honor the --no-systemd flag. But this should work when you're not using the --all option. Dimitri On Mon, Apr 19, 2021 at 10:41 AM Nico Schottelius < nico.schottelius@ungleich.ch> wrote:
Hey Dimitir,
because --no-systemd still requires systemd:
[19:03:00] server20.place6:~# ceph-volume lvm activate --all --no-systemd --> Executable systemctl not in PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin --> FileNotFoundError: [Errno 2] No such file or directory: 'systemctl': 'systemctl'
Best regards,
Nico

Hi,
My background is that ceph-volume activate does not work on non-systemd Linux distributions
Why not using the --no-systemd option during the ceph-volume activate command?
The systemd part is only enabling and starting the service but the tmpfs part should work if you're not using systemd

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].
Best regards,

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
