Lorin Hochstein 92c0445989 Use Vagrant's Ansible provisioner 
Use Vagrant's built-in support for Ansible provisioner. This eliminates the need
for a hosts file, and simplifies the ansible config file.

Renames config from .ansible.cfg to ansible.cfg since Ansible expects the file
to be called ansible.cfg and be adjacent to Vagrantfile when using the Vagrant
provisioner.

Ansible playbook for Ceph!

What does it do?

General support for:

  • Monitors
  • OSDs
  • MDSs
  • RGW

More details:

  • Authentication (cephx), this can be disabled.
  • Supports cluster public and private network.
  • Monitors deployment. You can easily start with one monitor and then progressively add new nodes. So can deploy one monitor for testing purpose. For production, I recommend to a
  • Object Storage Daemons. Like the monitors you can start with a certain amount of nodes and then grow this number. The playbook either supports a dedicated device for storing th
  • Metadata daemons.
  • Collocation. The playbook supports collocating Monitors, OSDs and MDSs on the same machine.
  • The playbook was validated on Debian Wheezy, Ubuntu 12.04 LTS and CentOS 6.4.
  • Tested on Ceph Dumpling and Emperor.
  • A rolling upgrade playbook was written, an upgrade from Dumpling to Emperor was performed and worked.

To re-run the Ansible provisioning scripts:

$ vagrant provision

Specifying fsid and secret key in production

The Vagrantfile specifies an fsid for the cluster and a secret key for the monitor. If using these playbooks in production, you must generate your own fsid in group_vars/all and monitor_secret in group_vars/mons. Those files contain information about how to generate appropriate values for these variables.
