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.

Betreff: [ceph-users] Orchestrator: Cannot add node after mistake

Hello,


I did a mistake, while deploying a new node on octopus.
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?


Thanks in advance,

Simon
