Re: [PROBLEM] Fail in deploy do ceph on RHEL

[David Turner <drakonstein@xxxxxxxxx>]

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.

I tried create new cluster ceph, but on the my first command, received this erro in blue.

Searched on the gogle about this erro, but believe that is error of the ssh, and dont of the ceph.

I tried:

alias ssh="ssh -t" on the admin node

I Modifyed the file 

Host node01

   Hostname node01.domain.local

   User sds

   PreferredAuthentications publickey

   IdentityFile /home/sds/.ssh/id_rsa

also try,

- start the command wtih sudo

-  Add PermitRootLogin whitout-password on /etc/ssh/sshd_config on the host node01

But, erro hold
