Chris St. Pierre 53af359c65 Improve firewall checks 
The firewall checks can fail for any number of reasons -- e.g., the
ceph cluster hostnames are unresolvable from the ansible host, or the
ports are filtered by some intermediate hop, etc. Make two changes to
make those checks better:

* Set pipefail when running the checks, so if nmap itself fails the
  command will be marked as 'failed'. Specifically, this fixes the
  case where the hostnames cannot be resolved.
* Add a new variable, check_firewall, which can be used to disable
  checks entirely. Specifically, this fixes the case where some
  intermediate firewall filters the ports, so nmap returns "filtered".

Ansible role: Ceph Common

This role does several things prior to bootstrapping your Ceph cluster:

  • Checks the system and validates that Ceph can be installed
  • Tunes the operating system if the node is an OSD server
  • Installs Ceph
  • Generates ceph.conf

Requirements

Move the plugins/actions/config_template.py file to your top level playbook directory. Edit your ansible.cfg like so:

action_plugins = plugins/actions

Depending on how you are managing your playbook, the path might be different so edit the file accordingly if necessary.
