6 This plug-in allows to enable or disable some features from the Ceph Dashboard
7 on-demand. When a feature becomes disabled:
8
9 - Its front-end elements (web pages, menu entries, charts, etc.) will become hidden.
10 - Its associated REST API endpoints will reject any further requests (404, Not Found Error).
11
12 The main purpose of this plug-in is to allow ad-hoc customizations of the workflows exposed
13 by the dashboard. Additionally, it could allow for dynamically enabling experimental
14 features with minimal configuration burden and no service impact.
15
16 The list of features that can be enabled/disabled is:
17
18 - **Block (RBD)**:
19 - Image Management: ``rbd``
20 - Mirroring: ``mirroring``
21 - iSCSI: ``iscsi``
22 - **Filesystem (Cephfs)**: ``cephfs``
23 - **Objects (RGW)**: ``rgw`` (including daemon, user and bucket management).
24
25 By default all features come enabled.
26
27 To retrieve a list of features and their current statuses::
28
29 $ ceph dashboard feature status
30 Feature 'cephfs': 'enabled'
31 Feature 'iscsi': 'enabled'
32 Feature 'mirroring': 'enabled'
33 Feature 'rbd': 'enabled'
34 Feature 'rgw': 'enabled'
35
36 To enable or disable the status of a single or multiple features::
37
38 $ ceph dashboard feature disable iscsi mirroring
39 Feature 'iscsi': disabled
40 Feature 'mirroring': disabled
41
42 After a feature status has changed, the API REST endpoints immediately respond to
43 that change, while for the front-end UI elements, it may take up to 20 seconds to
44 reflect it.
