Hi all, I need to restart a service on a few elasticsearch nodes. I'm trying to do it with pssh. I'm getting this error when I try to do that: pssh -h es_list "/bin/sudo -S /bin/systemctl restart elasticsearch" [1] 17:01:50 [FAILURE] bluethundr at es2.example.com Exited with error code 1 [2] 17:01:51 [FAILURE] bluethundr at es3.example.com Exited with error code 1 [3] 17:01:51 [FAILURE] bluethundr at es1.example.com Exited with error code 1 I have to sudo up from my user account as root logins are disallowed. However a simple 'echo hello' command that doesn't require sudo works fine: #pssh -h es_list "/bin/echo hello" [1] 17:00:40 [SUCCESS] bluethundr at es1.example.com [2] 17:00:41 [SUCCESS] bluethundr at es3.example.com [3] 17:00:41 [SUCCESS] bluethundr at es2.example.com What am I doing wrong?
