After some hours of searching around in the docs and finaly taking a look at the sourcecode of cephadm, I figured out it has to do with the docker software (podman in my case). So I figured out that podman is not installed on the new node. I never installed podman on any node so I don't know if my installation was not good, or if cephadm just had a problem installing it. Also the message in the error is not very meaningful. For example, if I forget to install python3, the "python3 is not installed" message is very clear.

The node is a fresh installed Centos8 machine. Bevore I did a "ceph orch host add node08" I pasted the wrong command: ceph orch daemon add osd node08:cl_node08/ceph That did not return anything, so I tried to add the node first with the host add command, but now I get an error: Error ENOENT: New host node08 (node08) failed check: ['Traceback (most recent call last):', ' File "<stdin>", line 4580, in <module>', ' File "<stdin>", line 3592, in command_check_host', "UnboundLocalError: local variable 'container_path' referenced before assignment"] I'm not a developer, so I don't know where to look, and how to fix this. I tried to reboot every node, to see if it's just a cached problem, but no luck there. Do any of you know how to fix this?
