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 infrastructure
|
|
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 throughout the Shared File
|
|
Systems service. It supports the OpenStack APIs.
|
|
|
|
manila-data
|
|
A standalone service whose purpose is to receive requests, process data
|
|
operations such as copying, share migration or backup, and send back a
|
|
response after an operation has been completed.
|
|
|
|
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 things like Capacity,
|
|
Availability Zone, Share Types, and Capabilities as well as custom filters.
|
|
|
|
manila-share
|
|
Manages back-end devices that provide shared file systems. A manila-share
|
|
process can run 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 used, the networking requirements are handled outside of
|
|
Manila.
