v12.0.3 Luminous (dev)
======================
Major changes from v12.0.2
--------------------------
-* The "journaler allow split entries" config setting has been removed.
Notable Changes
---------------
Major changes from v12.0.1
--------------------------
-* The original librados rados_objects_list_open (C) and objects_begin
- (C++) object listing API, deprecated in Hammer, has finally been
- removed. Users of this interface must update their software to use
- 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
- only external librados users might be affected.
-
- The newest (and recommended) rados_object_list_begin (C) and
- object_list_begin (C++) API is only usable on clusters with the
- SORTBITWISE flag enabled (Jewel and later). (Note that this flag is
- required to be set before upgrading beyond Jewel.)
-* CephFS clients without the 'p' flag in their authentication capability
- string will no longer be able to set quotas or any layout fields. This
- flag previously only restricted modification of the pool and namespace
- fields in layouts.
-* CephFS directory fragmentation (large directory support) is enabled
- by default on new filesystems. To enable it on existing filesystems
- use "ceph fs set <fs_name> allow_dirfrags".
-* CephFS will generate a health warning if you have fewer standby daemons
- than it thinks you wanted. By default this will be 1 if you ever had
- a standby, and 0 if you did not. You can customize this using
- ``ceph fs set <fs> standby_count_wanted <number>``. Setting it
- to zero will effectively disable the health check.
-* The "ceph mds tell ..." command has been removed. It is superceded
- by "ceph tell mds.<id> ..."
-* RGW introduces server side encryption of uploaded objects with 3 options for
- the management of encryption keys, automatic encryption (only recommended for
- test setups), customer provided keys similar to Amazon SSE-C specification and
- using a key management service (Openstack Barbician) similar to Amazon SSE-KMS
- specification.
Notable Changes
---------------
long term release. We're off to a good start to release Luminous in the spring
of '17.
-Major changes from Kraken
--------------------------
- * When assigning a network to the public network and not to
- the cluster network the network specification of the public
- network will be used for the cluster network as well.
- In older versions this would lead to cluster services
- being bound to 0.0.0.0:<port>, thus making the
- cluster service even more publicly available than the
- public services. When only specifying a cluster network it
- will still result in the public services binding to 0.0.0.0.
-
-* Some variants of the omap_get_keys and omap_get_vals librados
- functions have been deprecated in favor of omap_get_vals2 and
- omap_get_keys2. The new methods include an output argument
- indicating whether there are additional keys left to fetch.
- Previously this had to be inferred from the requested key count vs
- the number of keys returned, but this breaks with new OSD-side
- limits on the number of keys or bytes that can be returned by a
- single omap request. These limits were introduced by kraken but
- are effectively disabled by default (by setting a very large limit
- of 1 GB) because users of the newly deprecated interface cannot
- tell whether they should fetch more keys or not. In the case of
- the standalone calls in the C++ interface
- (IoCtx::get_omap_{keys,vals}), librados has been updated to loop on
- the client side to provide a correct result via multiple calls to
- the OSD. In the case of the methods used for building
- multi-operation transactions, however, client-side looping is not
- practical, and the methods have been deprecated. Note that use of
- either the IoCtx methods on older librados versions or the
- deprecated methods on any version of librados will lead to
- incomplete results if/when the new OSD limits are enabled.
-
-* In previous versions, if a client sent an op to the wrong OSD, the OSD
- would reply with ENXIO. The rationale here is that the client or OSD is
- clearly buggy and we want to surface the error as clearly as possible.
- We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
- is enabled (it's off by default). This means that a VM using librbd that
- previously would have gotten an EIO and gone read-only will now see a
- blocked/hung IO instead.
-
-* When configuring ceph-fuse mounts in /etc/fstab, a new syntax is
- available that uses "ceph.<arg>=<val>" in the options column, instead
- of putting configuration in the device column. The old style syntax
- still works. See the documentation page "Mount CephFS in your
- file systems table" for details.
