Thank you Eugen, it worked.
For the record this is what I have done to remove the services completely. My CephFS had
the name "testfs".
* `ceph orch ls mds mds.testfs --export yaml >change.yaml`
* removed the placement-spec from `change.yaml`.
* reapplied using `cephadm shell -m change.yaml -- ceph orch apply -I /mnt/change.yaml`
* removed daemons with `ceph orch daemon rm mds.testfs.<daemon-id>` for each daemon
listed in `ceph orch ps | grep mds.testfs`
* removed mds-set with `ceph orch rm mds.testfs`
* remove auth using `ceph auth rm mds.testfs.<daemon-id>` for each daemon listed in
`ceph auth ls | grep mds.testfs`
Regards,
Michael

Betreff: [ceph-users] Re: Removing an applied service set
Do you have a spec file for the mds services or how did you deploy the
services? If you have a yml file with the mds placement just remove
the entries from that file and run 'ceph orch apply -i mds.yml'.
You can export your current config with this command and then modify
the file to your need:
cephadm:~ # ceph orch ls mds mds.cephfs --export yaml
service_type: mds
service_id: cephfs
service_name: mds.cephfs
placement:
hosts:
- host5
- host6
Then if you apply the changes cephadm should not redeploy those
deleted services. It's possible that you have to clean-up `ceph auth
ls` and remove deleted mds keyrings. Also check `cephadm ls` on the
mds nodes if the containers have been removed.

Eugen
Zitat von Michael Wodniok <wodniok(a)wor.net>et>:
Hi,
we created multiple CephFS, this invloved deploying mutliple
mds-services using `ceph orch apply mds [...]`. Worked like a charm.
Now the filesystem has been removed and the leftovers of the
filesystem should also be removed, but I can't delete the services
as cephadm/orchestration module is recreating them. What is the
"official" way to delete this applied service set? Setting placement
size to 0 is not possible in Ceph 15.
Kind regards,
Michael
