Fuel Manila plugin
|
||||
==========================================
|
||||
|
||||
https://blueprints.launchpad.net/fuel-plugin-manila/+spec/initial-9.0
|
||||
|
||||
There is the Fuel plugin that installs and configures the Manila [0]_.
|
||||
|
||||
--------------------
|
||||
Problem description
|
||||
--------------------
|
||||
|
||||
There is the Manila project that provides a shared file system service for
|
||||
OpenStack. It's the new OpenStack project that provides coordinated access
|
||||
to shared or distributed file systems. The Manila has multiple storage
|
||||
backends (to support vendor or file system specific nuances/capabilities) that
|
||||
could work simultaneously on one environment.
|
||||
|
||||
The Fuel Manila plugin adds utilization the corresponding OpenStack service
|
||||
in an Fuel environment.
|
||||
|
||||
----------------
|
||||
Proposed changes
|
||||
----------------
|
||||
|
||||
Install the Manila inside an MOS environment. The python-manilaclient,
|
||||
manila-api and manila scheduler should works on controller. Manila-share and
|
||||
manila-data processes should works on nodes with new roles --- manila-share
|
||||
and manila-date accordingly. Upload the service image into glance (if generic
|
||||
driver is enabled in that environment).
