Hi, Any of you used cephadm bootstrap command without root user? On Wed, Aug 19, 2020 at 11:30 AM Amudhan P <amudhan83@gmail.com> wrote:

Hi,

I am trying to install ceph 'octopus' using cephadm. In bootstrap command, I have specified a non-root user account as ssh-user. cephadm bootstrap --mon-ip xx.xxx.xx.xx --ssh-user non-rootuser

when bootstrap about to complete it threw an error stating.

"""" INFO:cephadm:Non-zero exit code 2 from /usr/bin/podman run --rm --net=host --ipc=host -e CONTAINER_IMAGE=docker.io/ceph/ceph:v15 -e NODE_NAME=node1 - v /var/log/ceph/ae4ed114-e145-11ea-9c1f-0025900a8ebe:/var/log/ceph:z -v /tmp/ceph-tmpm22k9j9w:/etc/ceph/ceph.client.admin.keyring:z -v /tmp/ceph-tmpe 1ltigk8:/etc/ceph/ceph.conf:z --entrypoint /usr/bin/ceph docker.io/ceph/ceph:v15 orch host add node1 INFO:cephadm:/usr/bin/ceph:stderr Error ENOENT: Failed to connect to node1 (node1).

To confirm if I have used the right command been used during bootstrap. I have tried the below command.

" ceph config-key dump mgr/cephadm/ssh_user" { "mgr/cephadm/ssh_user": "non-rootuser" }

and the output shows the user I have used during bootstrap "non-rootuser"

but at the same time when I run cmd " ceph cephadm get-user " the output still shows 'root' as the user.

Why the change is not affecting? do anyone faced a similar issue in bootstrap?

Is there any way to avoid using container with cephadm?
