Reset unreachable hosts - Ansible

Question

How do I reset unreachable hosts in Ansible?

Suppose I have a flagged host and I want to reuse it, how do I do that?

Answer 1

If you try using the host that is not reachable. it'll throw a warning saying host unreachable and hence remove the host from the list of active hosts. To recover from this, you can use 

meta: clear_host_errors. 

This will reactivate all flagged hosts and you'll be able to use them again. 

Hope this helps:)
