This is the third development checkpoint release of Luminous, the next long term stable release. 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 It is superseded by "ceph tell mds.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 KMS specification & using a key management service (openstack barbician) For a more detailed changelog, refer to http://ceph.com/releases/ceph-v12-0-2-luminous-dev-released/ Getting Ceph ------------ * Git at git://github.com/ceph/ceph.git * Tarball at http://download.ceph.com/tarballs/ceph-12.0.2.tar.gz * For packages, see http://docs.ceph.com/docs/master/install/get-packages/ * For ceph-deploy, see http://docs.ceph.com/docs/master/install/install-ceph-deploy * Release sha1: 5a1b6b3269da99a18984c138c23935e5eb96f73e -- Abhishek Lekshmanan SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
