Ansible playbooks to deploy Ceph, the distributed filesystem
.... The default location for an inventory file is /etc/ansible/hosts but this file can be placed anywhere and used with the -i flag of ansible-playbook. You must have a playbook to pass to the ansible-playbook command when deploying your cluster. There is a sample playbook at the root of the ceph-ansible project called site.yml.sample. This playbook should work fine for most usages, but it does include by default every daemon group which might not be appropriate for your cluster setup.
