Release Notes
===============
-v12.1.1 Luminous (RC)
+v12.1.2 Luminous (RC)
=====================
-This is the second release candidate for Luminous, the next long term stable
+This is the third release candidate for Luminous, the next long term stable
release.
Ceph Luminous (v12.2.0) will be the foundation for the next long-term
either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
the new rados_object_list_begin (C) and object_list_begin (C++) API
before updating the client-side librados library to Luminous.
+
Object enumeration (via any API) with the latest librados version
and pre-Hammer OSDs is no longer supported. Note that no in-tree
Ceph services rely on object enumeration via the deprecated APIs, so
* ``ceph config-key put`` has been deprecated in favor of ``ceph config-key set``.
-* RGW: bucket index resharding now uses the reshard namespace in upgrade scenarios as well
- this is a changed behaviour from RC1 where a new pool for reshard was created
+
+Notable Changes since v12.1.1 (RC2)
+-----------------------------------
+
+* New "ceph -w" behavior - the "ceph -w" output no longer contains I/O rates,
+ available space, pg info, etc. because these are no longer logged to the
+ central log (which is what "ceph -w" shows). The same information can be
+ obtained by running "ceph pg stat"; alternatively, I/O rates per pool can
+ be determined using "ceph osd pool stats". Although these commands do not
+ self-update like "ceph -w" did, they do have the ability to return formatted
+ output by providing a "--format=<format>" option.
+
+* Pools are now expected to be associated with the application using them.
+ Upon completing the upgrade to Luminous, the cluster will attempt to associate
+ existing pools to known applications (i.e. CephFS, RBD, and RGW). In-use pools
+ that are not associated to an application will generate a health warning. Any
+ unassociated pools can be manually associated using the new
+ "ceph osd pool application enable" command. For more details see
+ "Associate Pool to Application" in the documentation.
+
+* ceph-mgr now has a Zabbix plugin. Using zabbix_sender it sends trapper
+ events to a Zabbix server containing high-level information of the Ceph
+ cluster. This makes it easy to monitor a Ceph cluster's status and send
+ out notifications in case of a malfunction.
+
+* The 'mon_warn_osd_usage_min_max_delta' config option has been
+ removed and the associated health warning has been disabled because
+ it does not address clusters undergoing recovery or CRUSH rules that do
+ not target all devices in the cluster.
+
+* Specifying user authorization capabilities for RBD clients has been
+ simplified. The general syntax for using RBD capability profiles is
+ "mon 'profile rbd' osd 'profile rbd[-read-only][ pool={pool-name}[, ...]]'".
+ For more details see "User Management" in the documentation.
+
+* RGW: bucket index resharding now uses the reshard namespace in log pool
+ upgrade scenarios as well this is a changed behaviour from RC1 where a
+ new pool for reshard was created
* RGW multisite now supports for enabling or disabling sync at a bucket level.
