Goutham Pacha Ravi bc4712e35e Manila install guide: Fix wrong instructions 
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 Installation Tutorial

get-started-with-shared-file-systems.rst install-controller-node.rst install-share-node.rst verify.rst post-install.rst next-steps.rst

The OpenStack Shared File Systems service (manila) provides coordinated access to shared or distributed file systems. The method in which the share is provisioned and consumed is determined by the Shared File Systems driver, or drivers in the case of a multi-backend configuration. There are a variety of drivers that support NFS, CIFS, HDFS, GlusterFS, CEPHFS and other protocols as well.

The Shared File Systems API and scheduler services typically run on the controller nodes. Depending upon the drivers used, the share service can run on controllers, compute nodes, or storage nodes.

Important

For simplicity, this guide describes configuring the Shared File Systems service to use one of either:

  • the generic back end with the driver_handles_share_servers mode (DHSS) enabled that uses the Compute service (nova), Image service (glance), Networking service (neutron) and Block storage service (cinder); or,
  • the LVM back end with driver_handles_share_servers mode (DHSS) disabled.

The storage protocol used and referenced in this guide is NFS. As stated above, the Shared File System service supports different storage protocols depending on the back end chosen.

For the generic back end, networking service configuration requires the capability of networks being attached to a public router in order to create share networks. If using this back end, ensure that Compute, Networking and Block storage services are properly working before you proceed. For networking service, ensure that option 2 (deploying the networking service with support for self-service networks) is properly configured.

This installation tutorial also assumes that installation and configuration of OpenStack packages, Network Time Protocol, database engine and message queue has been completed as per the instructions in the OpenStack Installation Tutorial.. The Identity Service (keystone) has to be pre-configured with suggested client environment scripts.

For more information on various Shared File Systems storage back ends, see the Shared File Systems Configuration Reference..
