groups in your Ceph configuration file, as the default is NOT ideal.
For details on placement group numbers refer to `setting the number of placement groups`_
+.. note:: Starting with Luminous, all pools need to be associated to the
+ application using the pool. See `Associate Pool to Application`_ below for
+ more information.
+
For example::
osd pool default pg num = 100
:Required: No.
:Default: 0, no splitting at the pool creation time.
+Associate Pool to Application
+=============================
+
+Pools need to be associated with an application before use. Pools that will be
+used with CephFS or pools that are automatically created by RGW are
+automatically associated. Pools that are intended for use with RBD should be
+initialized using the ``rbd`` tool (see `Block Device Commands`_ for more
+information).
+
+For other cases, you can manually associate a free-form application name to
+a pool.::
+
+ ceph osd pool application enable {pool-name} {application-name}
+
+.. note:: CephFS uses the application name ``cephfs``, RBD uses the
+ application name ``rbd``, and RGW uses the application name ``rgw``.
+
Set Pool Quotas
===============
If you created users with permissions strictly for a pool that no longer
exists, you should consider deleting those users too::
- ceph auth list | grep -C 5 {pool-name}
+ ceph auth ls | grep -C 5 {pool-name}
ceph auth del {user}
