Orchestrator CLI
|
||
================
|
||
|
||
This module provides a command line interface (CLI) to orchestrator
|
||
modules (ceph-mgr modules which interface with external orchestation services)
|
||
|
||
As the orchestrator CLI unifies different external orchestrators, a common nomenclature
|
||
for the orchestrator module is needed.
|
||
|
||
+--------------------------------------+---------------------------------------+
|
||
| host | hostname (not DNS name) of the |
|
||
| | physical host. Not the podname, |
|
||
| | container name, or hostname inside |
|
||
| | the container. |
|
||
+--------------------------------------+---------------------------------------+
|
||
| service type | The type of the service. e.g., nfs, |
|
||
| | mds, osd, mon, rgw, mgr, iscsi |
|
||
+--------------------------------------+---------------------------------------+
|
||
| service | A logical service, Typically |
|
||
| | comprised of multiple service |
|
||
| | instances on multiple hosts for HA |
|
||
| | |
|
||
| | * ``fs_name`` for mds type |
|
||
| | * ``rgw_zone`` for rgw type |
|
||
| | * ``ganesha_cluster_id`` for nfs type |
|
||
+--------------------------------------+---------------------------------------+
|
||
| service instance | A single instance of a service. |
|
||
| | Usually a daemon, but maybe not |
|
||
| | (e.g., might be a kernel service |
|
||
| | like LIO or knfsd or whatever) |
|
||
| | |
|
||
| | This identifier should |
|
||
| | uniquely identify the instance |
|
||
+--------------------------------------+---------------------------------------+
|
||
| daemon | A running process on a host; use |
|
||
| | “service instance” instead |
|
||
+--------------------------------------+---------------------------------------+
|
||
|
||
The relation between the names is the following:
|
||
|
||
* a service belongs to a service type
|
||
* a service instance belongs to a service type
|
||
* a service instance belongs to a single service group
|
||
|
||
Configuration
|
||
=============
|
||
|
||
To enable the orchestrator, please select the orchestrator module to use
|
||
with the ``set backend`` command::
|
||
|
||
ceph orchestrator set backend <module>
|
||
|
||
For example, to enable the Rook orchestrator module and use it with the CLI::
|
||
|
||
ceph mgr module enable rook
|
||
ceph orchestrator set backend rook
|
||
|
||
You can then check backend is properly configured::
|
||
|
||
ceph orchestrator status
|
||
|
||
Disable the Orchestrator
|
||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
To disable the orchestrator again, use the empty string ``""``::
|
||
|
||
ceph orchestrator set backend ""``
|
||
ceph mgr module disable rook
|
||
|
||
Usage
|
||
=====
|
||
|
||
.. warning::
|
||
|
||
The orchestrator CLI is unfinished and work in progress. Some commands will not
|
||
exist, or return a different result.
|
||
|
||
.. note::
|
||
|
||
Orchestrator modules may only implement a subset of the commands listed below.
|
||
Also, the implementation of the commands are orchestrator module dependent and will
|
||
differ between implementations.
|
||
|
||
Status
|
||
~~~~~~
|
||
|
||
::
|
||
|
||

|
||
to talk to it)
|
||
|
||
Also show any in-progress actions.
|
||
|
||
Host Management
|
||
~~~~~~~~~~~~~~~
|
||
|
||

List Devices
|
||
^^^^^^^^^^^^
|
||
|
||
Print a list of discovered devices, grouped by node and optionally
|
||
filtered to a particular node:
|
||
|
||
::
|
||
|
||
ceph orchestrator device ls [--host=...] [--refresh]
|
||
|
||
Example::
|
||
|
||

|
||
Create OSDs
|
||
^^^^^^^^^^^
|
||
|
||
Create OSDs on a group of devices on a single host::
|
||
|
||
ceph orchestrator osd create <host>:<drive>
|
||
ceph orchestrator osd create -i <path-to-drive-group.json>
|
||
|
||
|
||
The output of ``osd create`` is not specified and may vary between orchestrator backends.
|
||
|
||
Where ``drive.group.json`` is a JSON file containing the fields defined in
|
||
:class:`ceph.deployment_utils.drive_group.DriveGroupSpec`
|
||
|
||
Example::
|
||
|
||
# ceph orchestrator osd create 192.168.121.206:/dev/sdc
|
||

Decommission an OSD
|
||
^^^^^^^^^^^^^^^^^^^
|
||
::
|
||
|
||
ceph orchestrator osd rm <osd-id> [osd-id...]
|
||
|
||
Removes one or more OSDs from the cluster and the host, if the OSDs are marked as
|
||
``destroyed``.
|
||
|
||
Example::

||
|
||
# ceph orchestrator osd rm 4
|
||
{"status": "OK", "msg": "", "data": {"event": "playbook_on_stats", "uuid": "1a16e631-906d-48e0-9e24-fa7eb593cc0a", "stdout": "\r\nPLAY RECAP *********************************************************************\r\n192.168.121.158 : ok=2 changed=0 unreachable=0 failed=0 \r\n192.168.121.181 : ok=2 changed=0 unreachable=0 failed=0 \r\n192.168.121.206 : ok=2 changed=0 unreachable=0 failed=0 \r\nlocalhost : ok=31 changed=8 unreachable=0 failed=0 \r\n", "counter": 240, "pid": 10948, "created": "2019-05-28T22:26:09.264012", "end_line": 308, "runner_ident": "8c093db0-8197-11e9-b07a-2016b900e38f", "start_line": 301, "event_data": {"ignored": 0, "skipped": {"localhost": 37}, "ok": {"192.168.121.181": 2, "192.168.121.158": 2, "192.168.121.206": 2, "localhost": 31}, "artifact_data": {}, "rescued": 0, "changed": {"localhost": 8}, "pid": 10948, "dark": {}, "playbook_uuid": "a12ec40e-bce9-4bc9-b09e-2d8f76a5be02", "playbook": "shrink-osd.yml", "failures": {}, "processed": {"192.168.121.181": 1, "192.168.121.158": 1, "192.168.121.206": 1, "localhost": 1}}, "parent_uuid": "a12ec40e-bce9-4bc9-b09e-2d8f76a5be02"}}

Blink Device Lights
|
||
^^^^^^^^^^^^^^^^^^^
|
||
::
|
||
|
||
ceph orchestrator device ident-on <host> <devname>
|
||
ceph orchestrator device ident-off <host> <devname>
|
||
ceph orchestrator device fault-on <host> <devname>
|
||
ceph orchestrator device fault-off <host> <devname>
|
||
|
||
ceph orchestrator osd ident-on {primary,journal,db,wal,all} <osd-id>
|
||
ceph orchestrator osd ident-off {primary,journal,db,wal,all} <osd-id>
|
||
ceph orchestrator osd fault-on {primary,journal,db,wal,all} <osd-id>
|
||
ceph orchestrator osd fault-off {primary,journal,db,wal,all} <osd-id>
|
||
|
||
Where ``journal`` is the filestore journal, ``wal`` is the write ahead log of
|
||
bluestore and ``all`` stands for all devices associated with the osd
|
||
|
||
|
||
Monitor and manager management
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
Creates or removes MONs or MGRs from the cluster. Orchestrator may return an
|
||
error if it doesn't know how to do this transition.
|
||
|
||
Update the number of monitor nodes::
|
||
|
||
ceph orchestrator mon update <num> [host, host:network...]
|
||
|
||
Each host can optionally specify a network for the monitor to listen on.
|
||
|
||
Update the number of manager nodes::
|
||
|
||
ceph orchestrator mgr update <num> [host...]
|
||
|
||
..
|
||
.. note::
|
||
|
||
The host lists are the new full list of mon/mgr hosts
|
||
|
||
.. note::
|
||
|
||
specifying hosts is optional for some orchestrator modules
|
||
and mandatory for others (e.g. Ansible).
|
||
|
||
|
||
Service Status
|
||
~~~~~~~~~~~~~~
|
||
|
||
Print a list of services known to the orchestrator. The list can be limited to
|
||
services on a particular host with the optional --host parameter and/or
|
||
services of a particular type via optional --type parameter
|
||
(mon, osd, mgr, mds, rgw):
|
||
|
||
::
|
||
|
||
ceph orchestrator service ls [--host host] [--svc_type type] [--refresh]
|
||
|
||
Discover the status of a particular service::
|
||
|
||
ceph orchestrator service ls --svc_type type --svc_id <name> [--refresh]
|
||
|
||
|
||
Query the status of a particular service instance (mon, osd, mds, rgw). For OSDs
|
||
the id is the numeric OSD ID, for MDS services it is the file system name::
|
||
|
||
ceph orchestrator service-instance status <type> <instance-name> [--refresh]
|
||
|
||
|
||
|
||
Stateless services (MDS/RGW/NFS/rbd-mirror/iSCSI)
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
The orchestrator is not responsible for configuring the services. Please look into the corresponding
|
||
documentation for details.
|
||
|
||
The ``name`` parameter is an identifier of the group of instances:
|
||
|
||
* a CephFS file system for a group of MDS daemons,
|
||
* a zone name for a group of RGWs
|
||
|
||
Sizing: the ``size`` parameter gives the number of daemons in the cluster
|
||
(e.g. the number of MDS daemons for a particular CephFS file system).
|
||
|
||
Creating/growing/shrinking/removing services::
|
||
|
||
ceph orchestrator {mds,rgw} update <name> <size> [host…]
|
||
ceph orchestrator {mds,rgw} add <name>
|
||
ceph orchestrator nfs update <name> <size> [host…]
|
||
ceph orchestrator nfs add <name> <pool> [--namespace=<namespace>]
|
||
ceph orchestrator {mds,rgw,nfs} rm <name>
|
||
|
||
e.g., ``ceph orchestrator mds update myfs 3 host1 host2 host3``
|
||
|
||
Start/stop/reload::
|
||
|
||
ceph orchestrator service {stop,start,reload} <type> <name>
|
||
|
||
ceph orchestrator service-instance {start,stop,reload} <type> <instance-name>
|
