[chef] Re: Berks Debugging Tools

Soheil-

This is a known issue currently. We are waiting for the latest tagged
release from the ceph cookbook upstream. You can follow this issue at
https://github.com/ceph/ceph-cookbook/issues/188. Also I believe that
you can workaround this for now by pulling from the git master in the
Berksfile. For an example take a look at the statsd line
https://github.com/jjasghar/chef-openstack-testing-stack/blob/master/Berksfile#L20.
