# There is no clean way to restart hosts in ansible. The general issue is that
|
|
# the shutdown command may close sshd before ansible has time to "return" from
|
|
# the task, even with async & poll. This is due to the fact that asynchronous
|
|
# tasks still require a small synchronous bootstrapping script which takes 1 sec
|
|
# to complete, during which it is vulnerable to erroring out if sshd dies.
|
|
# To mitigate this, we prefix a sleep command before the shutdown so
|
|
# ansible has time to move on. For more info on this issue, see:
