The ceph module is intended to leverage all Ceph has to offer and allow for a wide range of use case. Although hosted on the OpenStack infrastructure, it does not require to sign a CLA nor is it restricted to OpenStack users. It benefits from a structured development process that helps federate the development effort. Each feature is tested with integration tests involving virtual machines to show that it performs as expected when used with a realistic scenario.

The ceph module deploys a Ceph cluster ( MON, OSD ), the Cephfs file system and the RadosGW object store. It provides integration with various environments ( OpenStack ... ) and components to be used by third party puppet modules that depend on a Ceph cluster.

A blueprint contains an inventory of what is desirable. It was decided to start from scratch and implement one module at a time.

We follow the OS compatibility of Ceph. With the release of infernalis this is currently:

• CentOS 7 or later
• Debian Jessie 8.x or later
• Ubuntu Trusty 14.04 or later
• Fedora 22 or later

• I want to try this module, heard of ceph, want to see it in action
• I want to operate a production cluster
• I want to run benchmarks on three new machines

Relies on rspec-beaker and tests are in spec/acceptance. It also requires Vagrant and Virtualbox .

bundle install
bundle exec rspec spec/acceptance

The BEAKER_set environment variable contains the resource set of linux distribution configurations for which integration tests are going to be run. Available values are

• two-centos-70-x64
• centos-70-x64
• two-ubuntu-server-1404-x64
• ubuntu-server-1404-x64

The default is
