|
------
|
|
|
|
* 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 MDS now supports dropping its cache for the purposes of benchmarking.
|
|
|
|
ceph tell mds.* cache drop <timeout>
|
|
|
|
Note that the MDS cache is cooperatively managed by the clients. It is
|
|
necessary for clients to give up capabilities in order for the MDS to fully
|
|
drop its cache. This is accomplished by asking all clients to trim as many
|
|
caps as possible. The timeout argument to the `cache drop` command controls
|
|
how long the MDS waits for clients to complete trimming caps. Keep in mind
|
|
that clients may still retain caps to open files which will prevent the
|
|
metadata for those files from being dropped by both the client and the MDS.
|
|
(This is an equivalent scenario to dropping the Linux
|
|
page/buffer/inode/dentry caches with some processes pinning some
|
|
inodes/dentries/pages in cache.)
|
|
|
|
* 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 <pgid> list_missing' command has been renamed to
|
|
'ceph pg <pgid> 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.
