I managed by experimenting how to get rid of that wrongly created MDS service, so for those who are looking for that information too, I used the following command: ceph orch rm mds.label:mds ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Thursday, May 27, 2021 9:16 PM, mabi <mabi@protonmail.ch> wrote:

Hello,

I am trying to place the two MDS daemons for CephFS on dedicated nodes. For that purpose I tried out a few different "cephadm orch apply ..." commands with a label but at the end it looks like I messed up with the placement as I now have two mds service_types as you can see below:

ceph orch ls --service-type mds --export

=========================================

service_type: mds service_id: ceph1fs service_name: mds.ceph1fs placement: count: 2 hosts:

- ceph1g - ceph1a

service_type: mds service_id: label:mds service_name: mds.label:mds placement: count: 2

This second entry at the bottom seems totally wrong and I would like to remove it but I haven't found how to remove it totally. Any ideas?

Ideally I just want to place two MDS daemons on node ceph1a and ceph1g.
