[SOLVED] Ceph, systemd and Killmode=none

[Urbaman]

Hi,

I am receiving the following message when restarting a node (so restarting ceph and osds on the node):

systemd[1]: /lib/systemd/system/ceph-volume@.service:8: Unit configured to use KillMode=none. This is unsafe, as it disables systemd's process lifecycle management for the service. Please update your service to use a safer KillMode=, such as 'mixed' or 'control-group'. Support for KillMode=none is deprecated and will eventually be removed.

I'm on the latest non-enterprise update.

Is there a way to solve/silence it?

Thank you.

it's just a deprecation warning, it will go away once the Ceph units are updated to no longer trigger it, but it's of no concern at the moment.

Ok thank you, I'll wait for next updates then.

I'm still seeing this in the syslogs (Nov 2023) so for what it's worth you can silence the error with

sudo nano /lib/systemd/system/ceph-volume@.service

Locate the line KillMode=none and change it to mixedor control-group. Make this change on all your CEPH nodes. When you're done, don't forget to run the command sudo systemctl daemon-reload.

Just checking what the recommendation is in Jan '24 .. do nothing or update ceph-volume@.service? If its update I am assuming its

killMode=mixed
