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 _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
