Hi,
I just tired that in my test cluster, removed the ceph.conf and admin
keyring from /etc/ceph and then added the _admin label to the host via
'ceph orch' and both were created immediately.
# no label for quincy-2
quincy-1:~ # ceph orch host ls
HOST ADDR LABELS STATUS
quincy-1 172.17.2.252 _admin
quincy-2 172.17.2.13
2 hosts in cluster
# moved existing files
quincy-2:~ # mv /etc/ceph/ceph.client.admin.keyring
/etc/ceph/xxxadminxxx.keyring
quincy-2:~ # mv /etc/ceph/ceph.conf /etc/ceph/conf
# added label
quincy-1:~ # ceph orch host label add quincy-2 _admin
Added label _admin to host quincy-2
# mgr deploys files

}
}
Zitat von Robert Sander <r.sander@xxxxxxxxxxxxxxxxxxx>:
Hi,
According to the documentation¹ the special host label _admin
instructs the cephadm orchestrator to place a valid ceph.conf and
the ceph.client.admin.keyring into /etc/ceph of the host.
I noticed that (at least) on 17.2.7 only the keyring file is placed
in /etc/ceph, but not ceph.conf.
Both files are placed into the /var/lib/ceph/<fsid>/config directory.
Has something changed?
