That error is a sudo error, not an SSH error. Making root login possible without password doesn't affect this at all. ceph-deploy is successfully logging in as sds to node01, but is failing to be able to execute sudo commands without a password. To fix that you need to use `visudo` to give the sds user the ability to run sudo commands with nopasswd.
