  ``activate``
  ============
  
- Once :ref:`ceph-volume-lvm-prepare` is completed, and all the various steps
- that entails are done, the volume is ready to get "activated".
+ After :ref:`ceph-volume-lvm-prepare` has completed its run, the volume can be
+ activated. 
  
- This activation process enables a systemd unit that persists the OSD ID and its
- UUID (also called ``fsid`` in Ceph CLI tools), so that at boot time it can
- understand what OSD is enabled and needs to be mounted.
+ Activating the volume involves enabling a ``systemd`` unit that persists the
+ ``OSD ID`` and its ``UUID`` (which is also called the ``fsid`` in the Ceph CLI
+ tools). After this information has been persisted, the cluster can determine
+ which OSD is enabled and must be mounted.

 +.. note:: The execution of this call is fully idempotent. This means that the
