[ceph-users] change user root to non-root after deploy cluster by cephadm

Hi guys I deployed the ceph cluster with cephadm and root user, but I need to change the user to a non-root user And I did these steps: 1- Created a non-root user on all hosts with access without password and sudo `$USER_NAME ALL = (root) NOPASSWD:ALL` 2- Generated a SSH key pair and use ssh-copy-it to add all hosts ` ssh-keygen (accept the default file name and leave the passphrase empty) ssh-copy-id USER_NAME@HOST_NAME ` 3 - ceph cephadm set-user <user>But I get "Error EINVAL: ssh connection to root@hostname failed" error How to deal with this issue? What should be done to change the user to non-root?
