Previously only the DHSS=True mode was documented in post install steps. The assumption that the generic driver was being configured existed in other places as well. * add DHSS=False documentation as necessary with the LVM driver. * correct assumptions in other places to clarify usage of appropriate share driver modes.

Shared File Systems service overview
|
|
====================================
|
|
|
|
The OpenStack Shared File Systems service (manila) provides file storage to a
|
|
virtual machine. The Shared File Systems service provides an abstraction
|
|
for managing and provisioning of file shares. The service also enables
|
|
management of share types as well as share snapshots if a driver supports
|
|
them.
|
|
|
|
The Shared File Systems service consists of the following components:
|
|
|
|
manila-api
|
|
A WSGI app that authenticates and routes requests to the Shared File
|
|
Systems service.
|
|
|
|
manila-data
|
|
A standalone service whose purpose is to process data operations such as
|
|
copying, share migration or backup.
|
|
|
|
manila-scheduler
|
|
Schedules and routes requests to the appropriate share service. The
|
|
scheduler uses configurable filters and weighers to route requests. The
|
|
Filter Scheduler is the default and enables filters on various attributes
|
|
of back ends, such as, Capacity, Availability Zone and other capabilities.
|
|
|
|
manila-share
|
|
Manages back-end devices that provide shared file systems. A manila-share
|
|
service talks to back-end devices by using share back-end drivers as
|
|
interfaces. A share driver may operate in one of two modes, with or
|
|
without handling of share servers. Share servers export file shares
|
|
via share networks. When share servers are not managed by a driver
|
|
within the shared file systems service, networking requirements should
|
|
be handled out of band of the shared file systems service.
|
|
|
|
Messaging queue
|
|
Routes information between the Shared File Systems processes.
