Re: how to restart daemons on 15.2 on Debian 10

[Sean Johnson <sean@xxxxxxxxx>]

I have OSD’s on the brain … that line should have read:

systemctl restart ceph-{fsid}@mon.{host}.service

In case that doesn’t work, there’s also a systemd service that contains the fsid of the cluster. 

So, in the case of a mon service you can also run: 

systemctl restart ceph-{fsid}@osd.{host}.service

Logs are correspondingly available via journalctl:

journalctl -u ceph-{fsid}@mon.{host}.service

Hello Michael,


I had the same problems. It's very unfamiliar, if you never worked with the cephadm tool.

The Way I'm doing it is to go into the cephadm container:
# cephadm shell

Here you can list all containers (for each service, one container) with the orchestration tool:

# ceph orch ps

and then restart it with the orchestration tool:

# ceph orch restart {name from ceph orch ps}


Hope it helps.


Ceers,

Simon

Hello List,

how do you restart daemons (mgr, mon, osd) on 15.2.1?

It used to be something like:
 systemctl stop ceph-osd@10

Or:
 systemctl start ceph-mon@ceph03

however, those command do nothing on my setup.

Is this because i use cephadm and that docker stuff?

The Logs also seem to be missing.
/var/log/ceph/5436dd5d-83d4-4dc8-a93b-60ab5db145df is pretty empty.

I feel like i am missing a lot of documentation here? Can anyone point
me to my missing parts?

Thanks a lot.

Cheers,
Michael
