Hi all,

I've set up a ceph cluster using this playbook:
https://github.com/ceph/ceph-ansible

I've configured in my hosts list
[mdss]
hostname1
hostname2
....

I now need to remove this MDS from the cluster.
The only document I found is this:
http://www.sebastien-han.fr/blog/2012/07/04/remove-a-mds-server-from-a-ceph-cluster/

# service ceph -a stop mds
=== mds.z-srv-m-cph02 ===
Stopping Ceph mds.z-srv-m-cph02 on z-srv-m-cph02...done
=== mds.r-srv-m-cph02 ===
Stopping Ceph mds.r-srv-m-cph02 on r-srv-m-cph02...done
=== mds.r-srv-m-cph01 ===
Stopping Ceph mds.r-srv-m-cph01 on r-srv-m-cph01...done
=== mds.0 ===
Stopping Ceph mds.0 on zrh-srv-m-cph01...done
=== mds.192.168.0.1 ===
Stopping Ceph mds.192.168.0.1 on z-srv-m-cph01...done
=== mds.z-srv-m-cph01 ===
Stopping Ceph mds.z-srv-m-cph01 on z-srv-m-cph01...done

[root@z-srv-m-cph01 ceph]# ceph mds stat
e1: 0/0/0 up

1. question: why the MDS are not stopped?
2. When I try to remove them:

# ceph mds rm mds.z-srv-m-cph01 z-srv-m-cph01
Invalid command: mds.z-srv-m-cph01 doesn't represent an int
mds rm <int[0-]> <name (type.id)> : remove nonactive mds
Error EINVAL: invalid command

The ansible playbook created me a conf like this in ceph.conf:
[mds]

[mds.z-srv-m-cph01]
host = z-srv-m-cph01

Can someone please help on this or at least give some hints?

Thank you very much
Gian
