Description of problem: https://github.com/ceph/ceph-ansible/pull/1558
This won't be landing in 3.1
This sounds like a great module for Gluster as well. I wonder if it should be in some other layer (system roles?).
The filtering mechanism was written for Ceph specifically and the device list comes from Ansible, but I suspect the skeleton could be shared and re-used more widely by other projects.
