14.0.1 ------ * The 'ceph osd rm' command has been deprecated. Users should use 'ceph osd destroy' or 'ceph osd purge' (but after first confirming it is safe to do so via the 'ceph osd safe-to-destroy' command). * The mon_health_preluminous_compat and mon_health_preluminous_compat_warning config options are removed, as the related functionality is more than two versions old. Any legacy monitoring system expecting Jewel-style health output will need to be updated to work with Nautilus. * Nautilus is not supported on any distros still running upstart so upstart specific files and references have been removed. * The 'ceph pg list_missing' command has been renamed to 'ceph pg list_unfound' to better match its behaviour. * The 'rbd-mirror' daemon can now retrieve remote peer cluster configuration secrets from the monitor. To use this feature, the 'rbd-mirror' daemon CephX user for the local cluster must use the 'profile rbd-mirror' mon cap. The secrets can be set using the 'rbd mirror pool peer add' and 'rbd mirror pool peer set' actions. * The `ceph mds deactivate` is fully obsolete and references to it in the docs have been removed or clarified. * The libcephfs bindings added the ceph_select_filesystem function for use with multiple filesystems. * The cephfs python bindings now include mount_root and filesystem_name options in the mount() function. >=13.1.0 -------- * The Telegraf module for the Manager allows for sending statistics to an Telegraf Agent over TCP, UDP or a UNIX Socket. Telegraf can then send the statistics to databases like InfluxDB, ElasticSearch, Graphite and many more. * The graylog fields naming the originator of a log event have changed: the string-form name is now included (e.g., ``"name": "mgr.foo"``), and the rank-form name is now in a nested section (e.g., ``"rank": {"type": "mgr", "num": 43243}``). * If the cluster log is directed at syslog, the entries are now prefixed by both the string-form name and the rank-form name (e.g., ``mgr.x mgr.12345 ...`` instead of just ``mgr.12345 ...``). * The JSON output of the ``osd find`` command has replaced the ``ip`` field with an ``addrs`` section to reflect that OSDs may bind to multiple addresses. * CephFS clients without the 's' flag in their authentication capability string will no longer be able to create/delete snapshots. To allow ``client.foo`` to create/delete snapshots in the ``bar`` directory of filesystem ``cephfs_a``, use command: - ``ceph auth caps client.foo mon 'allow r' osd 'allow rw tag cephfs data=cephfs_a' mds 'allow rw, allow rws path=/bar'`` * The ``osd_heartbeat_addr`` option has been removed as it served no (good) purpose: the OSD should always check heartbeats on both the public and cluster networks. * The ``rados`` tool's ``mkpool`` and ``rmpool`` commands have been removed because they are redundant; please use the ``ceph osd pool create`` and ``ceph osd pool rm`` commands instead. * The ``auid`` property for cephx users and RADOS pools has been removed. This was an undocumented and partially implemented capability that allowed cephx users to map capabilities to RADOS pools that they "owned". Because there are no users we have removed this support. If any cephx capabilities exist in the cluster that restrict based on auid then they will no longer parse, and the cluster will report a health warning like:: AUTH_BAD_CAPS 1 auth entities have invalid capabilities client.bad osd capability parse failed, stopped at 'allow rwx auid 123' of 'allow rwx auid 123' The capability can be adjusted with the ``ceph auth caps`` command. For example,:: ceph auth caps client.bad osd 'allow rwx pool foo' Upgrading from Luminous ----------------------- * During the upgrade from luminous to nautilus, it will not be possible to create a new OSD using a luminous ceph-osd daemon after the monitors have been upgraded to nautilus.
