Yesterday my teammates found a way to disable cephx authentication cluster wide (2 server cluster) in order to bypass issues that were preventing us from joining a 3rd server. Unfortunately they were uncertain which of the steps taken let to the successful addition. I request assistance getting my ceph operational again. Yesterday we left off after editing /etc/ceph/ceph.conf, turning authentication back on here, then copying the file to /var/lib/ceph///config and ensuring permissions were set to 644.

This got one command to work that had previously not been -- my ceph osd df correctly shows all 24 OSDs again, but I cannot run a ceph osd status nor a ceph orch status.

  • A copy of the ceph.conf is not required in `/var/lib/ceph/`. You need to make sure that the respective client keyring is in place (e.g. `/etc/ceph/ceph.client.admin.keyring`) and has the right key in it. Do you have a backup of the cluster conf like the output of `ceph auth ls`? It's strongly advised to do that before making any changes to the cluster, especially to the authentication. – eblock Oct 12 '20 at 15:09
