Telegraf is a agent for collecting and reporting metrics. It has multiple inputs and can send data to various outputs like for example InfluxDB or ElasticSearch. This module works by using the socket_listener of Telegraf and can send data over UDP, TCP and a local Unix Socket. Signed-off-by: Wido den Hollander <wido@42on.com>

13.0.1
|
|
------
|
|
|
|
* *RGW, MON*:
|
|
Commands variously marked as "del", "delete", "remove" etc. should now all be
|
|
normalized as "rm". Commands already supporting alternatives to "rm" remain
|
|
backward-compatible.
|
|
|
|
* *CephFS*:
|
|
|
|
* Upgrading an MDS cluster to 12.2.3+ will result in all active MDS
|
|
exiting due to feature incompatibilities once an upgraded MDS comes online
|
|
(even as standby). Operators may ignore the error messages and continue
|
|
upgrading/restarting or follow this upgrade sequence:
|
|
|
|
Reduce the number of ranks to 1 (`ceph fs set <fs_name> max_mds 1`), wait
|
|
for all other MDS to deactivate, leaving the one active MDS, upgrade the
|
|
single active MDS, then upgrade/start standbys. Finally, restore the
|
|
previous max_mds.
|
|
|
|
See also: https://tracker.ceph.com/issues/23172
|
|
|
|
* Several "ceph mds" commands have been obsoleted and replaced
|
|
by equivalent "ceph fs" commands:
|
|
- mds dump -> fs dump
|
|
- mds getmap -> fs dump
|
|
- mds stop -> mds deactivate
|
|
- mds set_max_mds -> fs set max_mds
|
|
- mds set -> fs set
|
|
- mds cluster_down -> fs set joinable false
|
|
- mds cluster_up -> fs set joinable true
|
|
- mds add_data_pool -> fs add_data_pool
|
|
- mds remove_data_pool -> fs rm_data_pool
|
|
- mds rm_data_pool -> fs rm_data_pool
|
|
|
|
* As the multiple MDS feature is now standard, it is now enabled by
|
|
default. ceph fs set allow_multimds is now deprecated and will be
|
|
removed in a future release.
|
|
|
|
* As the directory fragmentation feature is now standard, it is now
|
|
enabled by default. ceph fs set allow_dirfrags is now deprecated and
|
|
will be removed in a future release.
|
|
|
|
* MDS daemons now activate and deactivate based on the value of
|
|
max_mds. Accordingly, ceph mds deactivate has been deprecated as it
|
|
is now redundant.
|
|
|
|
* Taking a CephFS cluster down is now done by setting the down flag which
|
|
deactivates all MDS. For example: `ceph fs set cephfs down true`.
|
|
|
|
* Preventing standbys from joining as new actives (formerly the now
|
|
deprecated cluster_down flag) on a file system is now accomplished by
|
|
setting the joinable flag. This is useful mostly for testing so that a
|
|
file system may be quickly brought down and deleted.
|
|
|
|
* New CephFS file system attributes session_timeout and session_autoclose
|
|
are configurable via `ceph fs set`. The MDS config options
|
|
mds_session_timeout, mds_session_autoclose, and mds_max_file_size are now
|
|
obsolete.
|
|
|
|
* Each mds rank now maintains a table that tracks open files and their
|
|
ancestor directories. Recovering MDS can quickly get open files' pathes,
|
|
significantly reducing the time of loading inodes for open files. MDS
|
|
creates the table automatically if it does not exist.
|
|
|
|
* CephFS snapshot is now stable and enabled by default on new filesystems.
|
|
To enable snapshot on existing filesystems, use command:
|
|
- ceph fs set <fs_name> allow_new_snaps
|
|
|
|
The on-disk format of snapshot metadata has changed. The old format
|
|
metadata can not be properly handled in multiple active MDS configuration.
|
|
To guarantee all snapshot metadata on existing filesystems get updated,
|
|
perform the sequence of upgrading the MDS cluster strictly.
|
|
|
|
See http://docs.ceph.com/docs/master/cephfs/upgrading/
|
|
|
|
For filesystems that have ever enabled snapshot, the multiple-active MDS
|
|
feature is disabled by the new version MON. This will cause the "restore
|
|
previous max_mds" step in above URL to fail. To re-enable the feature,
|
|
either delete all old snapshots or scrub the whole filesystem:
|
|
|
|
- ceph daemon <mds of rank 0> scrub_path / force recursive repair
|
|
- ceph daemon <mds of rank 0> scrub_path '~mdsdir' force recursive repair
|
|
|
|
* *RBD*
|
|
|
|
* The RBD C API's rbd_discard method now enforces a maximum length of
|
|
2GB to match the C++ API's Image::discard method. This restriction
|
|
prevents overflow of the result code.
|
|
|
|
* The rbd CLI's "lock list" JSON and XML output has changed.
|
|
|
|
* The rbd CLI's "showmapped" JSON and XML output has changed.
|
|
|
|
* RBD now optionally supports simplified image clone semantics where
|
|
non-protected snapshots can be cloned; and snapshots with linked clones
|
|
can be removed and the space automatically reclaimed once all remaining
|
|
linked clones are detached. This feature is enabled by default if
|
|
the OSD "require-min-compat-client" flag is set to mimic or later; or can be
|
|
overridden via the "rbd_default_clone_format" configuration option.
|
|
|
|
* The sample ``crush-location-hook`` script has been removed. Its output is
|
|
equivalent to the built-in default behavior, so it has been replaced with an
|
|
example in the CRUSH documentation.
|
|
|
|
* The "rcceph" script (systemd/ceph in the source code tree, shipped as
|
|
/usr/sbin/rcceph in the ceph-base package for CentOS and SUSE) has been
|
|
dropped. This script was used to perform admin operations (start, stop,
|
|
restart, etc.) on all OSD and/or MON daemons running on a given machine.
|
|
This functionality is provided by the systemd target units (ceph-osd.target,
|
|
ceph-mon.target, etc.).
|
|
|
|
* The python-ceph-compat package is declared deprecated, and will be dropped
|
|
when all supported distros have completed the move to Python 3. It has
|
|
already been dropped from those supported distros where Python 3 is standard
|
|
and Python 2 is optional (currently only SUSE).
|
|
|
|
* The -f option of the rados tool now means "--format" instead of "--force",
|
|
for consistency with the ceph tool.
|
|
|
|
|
|
>= 13.0.2
|
|
---------
|
|
|
|
The ceph-rest-api command-line tool (obsoleted by the MGR "restful" module and
|
|
deprecated since v12.2.5) has been dropped.
|
|
|
|
There is a MGR module called "restful" which provides similar functionality
|
|
via a "pass through" method. See http://docs.ceph.com/docs/master/mgr/restful
|
|
for details.
|
|
|
|
|
|
13.0.2
|
|
------
|
|
|
|
* The format of the 'config diff' output via the admin socket has changed. It
|
|
now reflects the source of each config option (e.g., default, config file,
|
|
command line) as well as the final (active) value.
|
|
|
|
* The `pg force-recovery` command will not work for erasure-coded
|
|
PGs when a Luminous monitor is running along with a Mimic OSD.
|
|
Please use the recommended upgrade order of monitors before OSDs to
|
|
avoid this issue.
|
|
|
|
* It is no longer possible to adjust ``pg_num`` on a pool that is
|
|
still being created.
|
|
|
|
13.0.3
|
|
------
|
|
|
|
* The ``osd_mon_report_interval_min`` option has been renamed to
|
|
``osd_mon_report_interval``, and the ``osd_mon_report_interval_max``
|
|
(unused) has been eliminated. If this value has been customized on
|
|
your cluster then your configuration should be adjusted in order to
|
|
avoid reverting to the default value.
|
|
|
|
* *rados list-inconsistent-obj format changes:*
|
|
|
|
* Various error strings have been improved. For example, the "oi" or "oi_attr"
|
|
in errors which stands for object info is now "info" (e.g. oi_attr_missing is
|
|
now info_missing).
|
|
|
|
* The object's "selected_object_info" is now in json format instead of string.
|
|
|
|
* The attribute errors (attr_value_mismatch, attr_name_mismatch) only apply to user
|
|
attributes. Only user attributes are output and have the internal leading underscore
|
|
stripped.
|
|
|
|
* If there are hash information errors (hinfo_missing, hinfo_corrupted,
|
|
hinfo_inconsistency) then "hashinfo" is added with the json format of the
|
|
information. If the information is corrupt then "hashinfo" is a string
|
|
containing the value.
|
|
|
|
* If there are snapset errors (snapset_missing, snapset_corrupted,
|
|
snapset_inconsistency) then "snapset" is added with the json format of the
|
|
information. If the information is corrupt then "snapset" is a string containing
|
|
the value.
|
|
|
|
* If there are object information errors (info_missing, info_corrupted,
|
|
obj_size_info_mismatch, object_info_inconsistency) then "object_info" is added
|
|
with the json format of the information instead of a string. If the information
|
|
is corrupt then "object_info" is a string containing the value.
|
|
|
|
* *rados list-inconsistent-snapset format changes:*
|
|
|
|
* Various error strings have been improved. For example, the "ss_attr" in
|
|
errors which stands for snapset info is now "snapset" (e.g. ss_attr_missing is
|
|
now snapset_missing). The error snapset_mismatch has been renamed to snapset_error
|
|
to better reflect what it means.
|
|
|
|
* The head snapset information is output in json format as "snapset." This means that
|
|
even when there are no head errors, the head object will be output when any shard
|
|
has an error. This head object is there to show the snapset that was used in
|
|
determining errors.
|
|
|
|
|
|
* The config-key interface can store arbitrary binary blobs but JSON
|
|
can only express printable strings. If binary blobs are present,
|
|
the 'ceph config-key dump' command will show them as something like
|
|
``<<< binary blob of length N >>>``.
|
|
|
|
* The Ceph LZ4 compression plugin is now enabled by default, and introduces
|
|
a new build dependency.
|
|
|
|
* Monitors will now prune on-disk full maps if the number of maps grows above
|
|
a certain number (mon_osdmap_full_prune_min, default: 10000), thus
|
|
preventing unbounded growth of the monitor data store. This feature is
|
|
enabled by default, and can be disabled by setting
|
|
`mon_osdmap_full_prune_enabled` to false.
|
|
|
|
* Bootstrap auth keys will now be generated automatically on a fresh
|
|
deployment; these keys will also be generated, if missing, during upgrade.
|
|
|
|
* The (read-only) Ceph manager dashboard introduced in Ceph Luminous has been
|
|
replaced with a new implementation, providing a drop-in replacement offering
|
|
a number of additional management features. To access the new dashboard, you
|
|
first need to define a username and password. See the documentation for a
|
|
feature overview and installation instructions:
|
|
http://docs.ceph.com/docs/master/mgr/dashboard/
|
|
|
|
* The 'osd force-create-pg' command now requires a force option to
|
|
proceed because the command is dangerous: it declares that data loss
|
|
is permanent and instructs the cluster to proceed with an empty PG
|
|
in its place, without making any further efforts to find the missing
|
|
data.
|
|
|
|
* 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.
