This is a mechanically generated change to replace openstack.org git:// URLs with https:// equivalents. This is in aid of a planned future move of the git hosting infrastructure to a self-hosted instance of gitea (https://gitea.io), which does not support the git wire protocol at this stage. This update should result in no functional change. For more information see the thread at http://lists.openstack.org/pipermail/openstack-discuss/2019-March/003825.html Change-Id: Ic26c3b70e5c08d7b2ba0cfb6a6a9fb99edc92a11

CephFS
|
|
===============================
|
|
|
|
CephFS has recently gone GA and we can now move forward with offering
|
|
this to people as a charm. Up until this point it was considered too
|
|
experimental to store production data on.
|
|
|
|
Problem Description
|
|
===================
|
|
|
|
A new CephFS charm will be created. This charm will leverage the Ceph
|
|
base layer.
|
|
|
|
Proposed Change
|
|
===============
|
|
|
|
A new CephFS charm will be created. This charm will leverage the Ceph
|
|
base layer. The effort required should be small once the Ceph base
|
|
layer is ready to go.
|
|
|
|
Alternatives
|
|
------------
|
|
|
|
GlusterFS is an alternative to CephFS and will probably fit many users
|
|
needs. However there are users who don't want to deploy additional
|
|
hardware to create another cluster so this can be convenient in those
|
|
cases.
|
|
|
|
Implementation

- Create an interface to allow other charms to mount the filesytem.
|
|
|
|
Repositories
|
|
------------
|
|
|
|
A new git repository will be required to host the ceph-fs charm:
|
|
|
|
.. code-block:: bash
|
|
|
|
https://git.openstack.org/openstack/charm-ceph-fs
|
|
|
|
Documentation
|
|
-------------
|
|
|
|
A README.md will be created for the charm as part of the normal development
|
|
workflow.
|
|
|
|
Security
|
|
--------
|
|
|
|
No additional security concerns.
|
|
|
|
Testing
|
|
-------
|
|
|
|
A mojo spec will be developed to exercise this charm along with amulet tests
|
|
if needed:
|
|
|
|
* Deploy ceph-mon
|
|
* Deploy ceph-osd
|
|
* Deploy cephfs
|
|
* Relate the three
