Error initializing cluster client: ObjectNotFound('RADOS object not found (error calling conf_read_file)')
I have installed simple ceph system with two nodes (ceph100, ceph101) with cephadm and ceph orch host add command. I put the ssh-copy-id -f -i /etc/ceph/ceph.pub key to the second host (ceph101). I can execute the ceph -s command from the first host(ceph100) but when I execute the command in the second host(ceph101), I get the following error. Error initializing cluster client: ObjectNotFound('RADOS object not found (error calling conf_read_file)') Also, when I execute the 'ceph orch ps' command the output seems suspicious to me. NAME HOST STATUS REFRESHED AGE VERSION IMAGE NAME IMAGE ID CONTAINER ID mon.ceph101 ceph101 starting - - <unknown> <unknown> <unknown> <unknown> Has anyone any idea what could be the problem or anyone give me a fine link for the octopus cephadm installation? Regards.
Hello, When you deploy ceph to other nodes with the orchestrator, they "just" have the containers you deployed to them. This means in your case, you started the monitor container on ceph101 and you must have installed at least the ceph-common package (else the ceph command would not work). If you enter the command ceph -s there is no configuration file, nor is there a key file (ceph does not know, where to connect). Ceph's configuration directory defaults to /etc/ceph/ (should be empty or not exist on ceph101). So in your case, you can either create the configuration files manually (read throug "ceph auth" and how the config and the keyring file should look like), or just copy the ceph.conf and the admin keyring to /etc/ceph/ on ceph101.

Thanks Simon, as you mentioned, I did the missing things and now everything works fine. On Tue, Jun 16, 2020 at 9:30 AM Simon Sutter <ssutter@hosttech.ch> wrote:
