Selecting disks to be used by Ceph-Ansible

Why do we need a module for selecting disks ?

The legacy approach to select disks on a set of servers is to use their logical names like "/dev/sdx".

Using a logical name to point a device have the following drawbacks:

• the device path is not consistent over time : {add|remov}ing devices change the name
