The authentication messages described here are specific to the cephx
auth implementation. The messages are transferred by the Messenger
protocol or by MAuth messages, depending on the version of the

+Protocol
+--------
+For a detailed description of the v2 wire protocol, see :ref:`msgr2-protocol`.
* The number of placement groups (PGs) per pool can now be decreased
at any time, and the cluster can automatically tune the PG count
based on cluster utilization or administrator hints.
- * The new *v2* wire protocol brings support for encryption on the wire.
+ * The new :ref:`v2 wire protocol <msgr2>` brings support for encryption on the wire.
* Physical storage devices consumed by OSD and Monitor daemons are
now tracked by the cluster along with health metrics (i.e.,
SMART), and the cluster can apply a pre-trained prediction model
#. Verify the cluster is healthy with ``ceph health``.
