Orchestrator CLI
================
This module provides a command line interface (CLI) to orchestrator
modules (ceph-mgr modules which interface with external orchestration 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
~~~~~~
::
ceph orchestrator status
Show current orchestrator mode and high-level status (whether the module able
to talk to it)
Also show any in-progress actions.
Host Management
~~~~~~~~~~~~~~~
List hosts associated with the cluster::
ceph orchestrator host ls
Add and remove hosts::
ceph orchestrator host add <host>
ceph orchestrator host rm <host>
OSD 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::
# ceph orchestrator device ls
Host 192.168.121.206:
Device Path Type Size Rotates Available Model
/dev/sdb hdd 50.0G True True ATA/QEMU HARDDISK
/dev/sda hdd 50.0G True False ATA/QEMU HARDDISK
Host 192.168.121.181:
Device Path Type Size Rotates Available Model
/dev/sdb hdd 50.0G True True ATA/QEMU HARDDISK
/dev/sda hdd 50.0G True False ATA/QEMU HARDDISK
.. note::
Output form Ansible orchestrator
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
{"status": "OK", "msg": "", "data": {"event": "playbook_on_stats", "uuid": "7082f3ba-f5b7-4b7c-9477-e74ca918afcb", "stdout": "\r\nPLAY RECAP *********************************************************************\r\n192.168.121.206 : ok=96 changed=3 unreachable=0 failed=0 \r\n", "counter": 932, "pid": 10294, "created": "2019-05-28T22:22:58.527821", "end_line": 1170, "runner_ident": "083cad3c-8197-11e9-b07a-2016b900e38f", "start_line": 1166, "event_data": {"ignored": 0, "skipped": {"192.168.121.206": 186}, "ok": {"192.168.121.206": 96}, "artifact_data": {}, "rescued": 0, "changed": {"192.168.121.206": 3}, "pid": 10294, "dark": {}, "playbook_uuid": "409364a6-9d49-4e44-8b7b-c28e5b3adf89", "playbook": "add-osd.yml", "failures": {}, "processed": {"192.168.121.206": 1}}, "parent_uuid": "409364a6-9d49-4e44-8b7b-c28e5b3adf89"}}
.. note::
Output form Ansible orchestrator
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 <dev_id>
ceph orchestrator device ident-on <dev_name> <host>
ceph orchestrator device fault-on <dev_id>
ceph orchestrator device fault-on <dev_name> <host>
ceph orchestrator device ident-off <dev_id> [--force=true]
ceph orchestrator device ident-off <dev_id> <host> [--force=true]
ceph orchestrator device fault-off <dev_id> [--force=true]
ceph orchestrator device fault-off <dev_id> <host> [--force=true]
where ``dev_id`` is the device id as listed in ``osd metadata``,
``dev_name`` is the name of the device on the system and ``host`` is the host as
returned by ``orchestrator host ls``
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>
