[Ceph-ansible] Question about logging and debugging

Hello, This might be a more general Ansible question, but I will have other Ceph-Ansible questions, so I thought I'd start here.   If this is a basic Ansible question, I'd be grateful for a link to a useful tutorial. Question:  If I understand Ansible correctly, at the far end of it all ansible-playbook issues commands to hosts via SSH.  I'm looking for how to have those commands dumped to a log file rather than actually issuing them to the target hosts, especially for commands that actually cause a change on the host. In other words, while the standard output during a Ceph ansible-playbook run is interesting and useful, there's a lot of intermediate information.  OTOH, in the end a ceph-volume command is issued for an OSD node.  I'd like to be able to look at it and see if it looks right.  If not, I need to go back to my inventory file or my group-vars and make an adjustment or fix an error. Thanks. -Dave -- Dave Hall Binghamton University
